You can provide your own flouride (live in a house with well water).

jedberg11• 1 year ago

Assuming you're wealthy enough and well informed enough to know that you should.

kstrauser• 1 year ago

You can provide lots of stuff yourself if the state abandons the whole idea of public health. Of course, be prepared for your taxes and/or insurance going up to cover your neighbors who don't pay for the same preventative care.

Pretty much-was told by an insurance broker one of the biggest factors past history of weather and the obvious things (flooding possibility, dry trees) is my neighbors. Didn't get into specifics but I suspect drugs and gangs.

This is so dumb, and based on psudoscience at best, and straight up falsities at worst.

In 10 years we're going to hear about how cavities are so much higher in Utah than anywhere else.

jedberg11• 1 year ago

Those are based on countries with much higher levels of fluoride than the USA adds.

Follow up studies have found the levels in the USA to be perfectly safe and in fact beneficial since poor people don't get dental care like they do in other countries.

cosmotic• 1 year ago

I didnt look too closely, but the concentration recommended by the FDA is much lower than many of the sample sets in that linked study. Some 10 times as much. One is a hundred times as much.

Not sure if that first link was to the Harvard summary intentionally but heres the actual study: https://ehp.niehs.nih.gov/doi/10.1289/ehp.1104912

jcranmer2• 1 year ago

Fluoride is known to be problematic at high concentrations (hell, everything is). The problems of fluoride really start to come into play at concentrations of around 10-20mg/L, and some of the areas being studied are running well in excess of 100mg/L of fluoride.

The EPA limit for fluoride is 4mg/L. There's an argument to be made that it should be lowered to 2mg/L. When fluoride is added to drinking water, the target is around 0.9mg/L--no one's coming close to the EPA limit, and that exists because groundwater sources can end up being naturally high in fluoride. (I'm not sure what the typical natural occurrence of fluoride is in Utah, but I strongly suspect that they're not making any moves to actually remove fluoride from existing systems.)

I don't know whether water fluoridation is worthwhile. But I do know that various European countries have discontinued it. <https://web.archive.org/web/20160303202219/http://www.appgaf...> Are they also working off of pseudoscience and falsities?

stop502• 1 year ago

Don't they sell toothpaste with flourid in Utah?

jedberg11• 1 year ago

Generally kids don't use toothpaste with fluoride because of the risk of swollowing it. Yes, we know it's bad in high doses, which is why kids toothpaste often doesn't have it. You have to wait until they are old enough to spit when brushing.

In reality what will happen is that rich kids will be just fine because they will get their fluoride treatments at the dentist every six months.

It's the poor kids who will suffer because they don't see the dentist regularly because it's expensive, so they won't get their treatments.

dataflow11• 1 year ago

What is the best evidence in favor of this?

jsbisviewtiful• 1 year ago

There isn’t any. The very little research showing any effects on cognitive abilities are experiments using very high fluoride levels - nowhere near the levels in water. Like most conservative “stances”, it’s a farce.

dataflow11• 1 year ago

Thanks. I guess then my next question is, why are they doing this? Whom is it benefiting? Big Water?

rayiner9• 1 year ago

Why did many European countries discontinue fluoridation? https://www.euronews.com/health/2024/11/23/trump-could-push-...

However, in 1973, the Dutch Supreme Court ruled that there was no legal basis for fluoridation…. The debate hasn’t been meaningfully revived since then, Hofman told Euronews Health. "People started to say, ‘Well, the government should not give us some medicine [when] we cannot choose where to buy our drinking water from," she said.

That’s the “little c” conservative viewpoint. You don’t need to prove it’s harmful. The default should be not putting chemicals in everyone’s drinking water.

pfannkuchen3• 1 year ago

How do you prove no effect on any bodily system long term? People don’t like to talk about it, or they pretend otherwise, but this is basically impossible.

If the benefit is great enough then the risk makes sense. That is the case in a lot of areas. Is it worth taking a risk of an unknown effect somewhere in the body in exchange for… a marked but not even drastic reduction in cavities…? Not sure…

chneu• 1 year ago

I'd like to point out that fluoride was previously very much a liberal stance until the rise in MAGA/Qanon conservatives.

I grew up in the PNW of the USA and lots of small hippie towns have been removing fluoride for decades. It comes up on city ballots every year in Oregon.

concordDance5• 1 year ago

This stance is a bit confusing...

When it comes to things like radioactivity we assume a linear no threshhold model (e.g. that lower concentrations still have effects, just our measuring tools aren't good enough to detect it) and spend billions as a result. Why wouldn't we do the same for flouride?

How did you compile this list? Asking some LLM service?

From the first link:

It is important to note that there were insufficient data to determine if the low fluoride level of 0.7 mg/L currently recommended for U.S. community water supplies has a negative effect on children’s IQ

It doesn't seem in favor of this?

culi3• 1 year ago

Actual reseachers don't really talk about links to IQ. The main concern is actually around dental fluorosis. Too much flouride can replace minerals in your teeth causing them to become brittle over time

There's a subset of researchers that argue that now that fluoride toothpaste is widespread, the benefit of fluoridating water is much much smaller than it first was and the (small) risk of fluorosis is now comparatively more significant

stefan_2• 1 year ago

Where "main concern" means not a practical concern at all. You are adopting the talking points of cranks when what is of actual concern is things like drinking sugar, negligent parents or basic access to dental healthcare or even just dental education.

The CDC tracks some key indicators like mean decayed, missing or filled teeth (DMFT) and in critical age groups like 12-15 there has been no progress made in the past 20 years and the US continue lagging behind European countries: https://www.cdc.gov/oral-health/media/pdfs/Oral-Health-Surve...

And none of that has anything to do with fluoride in the water or not.

kilimounjaro2• 1 year ago

“ Actual reseachers don't really talk about links to IQ.”

Sorry but this reddit consensus is out of step with actual researchers. The #1 paediatric journal has published quite a bit on this recently. Basically the evidence isn’t of high quality but what we have doesn’t look great.

https://jamanetwork.com/journals/jamapediatrics/fullarticle/...

TeaBrain2• 1 year ago

Another question is whether there's still evidence for continuing to fluoridate water with how common toothpaste use is now. If nothing else, if it isn't providing benefits over toothpaste use, then fluoridating water could just be a waste of public funds.

2012: https://fluoridealert.org/content/50-reasons/

Highly recommend visiting the link for details about each point an references (it is not that long), here is a summary, don't comment if you haven't visited the link:

1) Fluoride is the only chemical added to water for the purpose of medical treatment. 2) Fluoridation is unethical. 3) The dose cannot be controlled. 4) The fluoride goes to everyone regardless of age, health or vulnerability. 5) People now receive fluoride from many other sources besides water. 6) Fluoride is not an essential nutrient. 7) The level in mothers’ milk is very low. 9) No health agency in fluoridated countries is monitoring fluoride exposure or side effects. 10) There has never been a single randomized controlled trial to demonstrate fluoridation’s effectiveness or safety. 11) Benefit is topical not systemic. 12) Fluoridation is not necessary. 13) Fluoridation’s role in the decline of tooth decay is in serious doubt. 14) NIH-funded study on individual fluoride ingestion and tooth decay found no significant correlation. 15) Tooth decay is high in low-income communities that have been fluoridated for years. 16) Tooth decay does not go up when fluoridation is stopped. 17) Tooth decay was coming down before fluoridation started. 18) The studies that launched fluoridation were methodologically flawed. 19) Children are being over-exposed to fluoride. 20) The highest doses of fluoride are going to bottle-fed babies. 21) Dental fluorosis may be an indicator of wider systemic damage. 22) Fluoride may damage the brain. 23) Fluoride may lower IQ. 24) Fluoride may cause non-IQ neurotoxic effects. 25) Fluoride affects the pineal gland. 26) Fluoride affects thyroid function. 27) Fluoride causes arthritic symptoms. 28) Fluoride damages bone. 29) Fluoride may increase hip fractures in the elderly. 30) People with impaired kidney function are particularly vulnerable to bone damage. 31) Fluoride may cause bone cancer (osteosarcoma). 32) Proponents have failed to refute the Bassin-Osteosarcoma study. 33) Fluoride may cause reproductive problems. 34) Some individuals are highly sensitive to low levels of fluoride as shown by case studies and double blind studies. 35) Other subsets of population are more vulnerable to fluoride’s toxicity. 36) There is no margin of safety for several health effects. 37) Low-income families penalized by fluoridation. 38) Black and Hispanic children are more vulnerable to fluoride’s toxicity. 39) Minorities are not being warned about their vulnerabilities to fluoride. 40) Tooth decay reflects low-income not low-fluoride intake. 41) The chemicals used to fluoridate water are not pharmaceutical grade. 42) The silicon fluorides have not been tested comprehensively. 43) The silicon fluorides may increase lead uptake into children’s blood. 44) Fluoride may leach lead from pipes, brass fittings and soldered joints. 45) Key health studies have not been done. 46) Endorsements do not represent scientific evidence. 47) Review panels hand-picked to deliver a pro-fluoridation result. 48) Many scientists oppose fluoridation. 49) Proponents usually refuse to defend fluoridation in open debate. 50) Proponents use very dubious tactics to promote fluoridation.

kelipso9• 1 year ago

Way past time. The link between fluoride ingestion by children and pregnant women to lower IQ in children has been known for years. It's incredible how the scientific community in the US is so ignorant of this fact.

Also, dentists have no neuroscience background! So let's take recommendations by dentists to ingest a neurotoxin with deep deep skepticism, shall we?

jcranmer2• 1 year ago

As the saying goes, it's the dose that makes the poison.

Vitamin D is also quite toxic, would you celebrate banning that as well?

kelipso9• 1 year ago

Yes, there is no need to add vitamin D into the water supply.

jedberg11• 1 year ago

The link between fluoride ingestion by children and pregnant women to lower IQ in children has been known for years

Not at the levels it is found in water in the USA. Those studies were done in countries with much higher levels of fluoride.

stop502• 1 year ago

Or where the people drink much more water

kelipso9• 1 year ago

A low dose of this neurotoxin can still have smaller adverse effects on IQ, and in all likelihood do, especially for fetuses and small children. Lots of countries have banned fluoridation of the water supply. The US has one of the highest fluoride levels in the water supply. The default should be to not add neurotoxins into the water supply (I cannot believe I have to actually say this).

jiggawatts2• 1 year ago

The relationship appears to be linear down to zero, but it’s very hard to study near those levels. From what I’ve seen, the best current science is that the fluoridation levels in typical western countries are reducing average IQ by about 0.5-1.5 points.

For reference, adding lead to fuel was far, far worse.

tayo424• 1 year ago

Republican state lawmaker Stephanie Gricius - who introduced the bill in the state legislature - has argued that there is research suggesting fluoride could have possible cognitive effects in children.

It's kind of amazing to say something like that then be so inconsistent on things that will have real outcomes that make life better for kids. They're all for cutting school support and social services.

Utah and Massachusetts are basically the steel-man versions of their respective ideologies. But Utah doesn’t have the benefit of Harvard and MIT, major Pharma companies, etc. It’s surrounded by desert and has no natural resources to speak of.

croes• 1 year ago

Doesn’t that contradict the negative outcome of fluoride in the water?

jedberg11• 1 year ago

A lot of that is due to the Mormons. While they tend to vote Republican, they are some of the biggest socialists out there. They believe in giving 10% of their income to the church (and enforce it!).

Then they redistribute to their poorest members in the form of free private education at all pre-college levels and highly subsidized college as well. And with food banks, free or subsidized medical services, and whole bunch of other things the government doesn't provide.

They've essentially traded one government for another, but theirs requires belief in their religion and only applies to their believers (who happen to concentrate in Utah).

BJones12• 1 year ago

Note that while this may be first state to ban fluoride, it's not the first state to not have fluoride in the water. That would be Hawaii (effectively).

Hawaii does not add fluoride to their water. Utah may be the first to out-right ban it, but there are quite a few local communities and cities that opt-out of adding it to their drinking water.

lolinder5• 1 year ago

Yeah, this is one of those places where because RFK Jr took the anti- stand there's an understandable assumption that it's more nutty anti-science stuff, but it's much less clear cut when it comes to fluoridation. Europe has much lower rates than the US, which is an outlier on these stats only approached by Australia, and before Utah the major high profile anti-fluoride stance was made by Portland:

To the extent this is a polarized left-right issue, it's only recently and only because everything is polarized right now.

jemmyw2• 1 year ago

I was surprised to learn this. "Worldwide, the Irish Republic, Singapore and New Zealand are the only countries which implement mandatory water fluoridation."

I live in New Zealand and my town doesn't put fluoride in the water but it seems like they'll be made to do so fairly soon. I don't really care one way or the other from the point of view of ingesting the stuff, but I do consider it a bit of a waste of money. People who brush with toothpaste don't need this and people who don't are probably drinking too much soda. A more useful thing to do might be to subsidize toothpaste for people who can't / won't buy it for their kids.

elif2• 1 year ago

Fluoridation, imperial measurement, 20% tips, taxes added at the register, and circumcision are the weirdest things Americans think everyone does.

habosa3• 1 year ago

Many other places fluoridate salt. There’s many ways to get flourish (toothpaste being the best if you can get people to use it correctly) but the evidence that mass fluoridation of some kind is good for dental health is enormous.

EasyMark8• 1 year ago

It seems like they could compare states/countries/cities while controlling for other factors (age, income level, etc) to see how well fluoridation works. I'm pretty sure you'll find that fluoridation helps lower the number of cavities, but it's not going to be a slam dunk.

jiggawatts2• 1 year ago

I initially dismissed it as the same category of stupid as anti-vax beliefs, but it turns out that there are a decent amount of good studies showing a link between fluoride in water and (slightly) lower IQ when pregnant mothers ingest the fluoride. Note that there is no significant effect after birth.

The idea is to remove fluoride from water and advise pregnant women to use fluoride-free toothpaste.

Everyone else can get enough fluoride from modern toothpastes, or regular dentist treatments.

The logic is that fluoride in tap water made sense in the era before toothpaste had it, but now it is “overmedicating” a vulnerable fraction of the population.

culi3• 1 year ago

The IQ link is very heavily lacking in evidence.

In the actual research the main "risk" posed by flouridated water is actually fluorosis. This causes minerals in your enamel to be replaced with flouride which can cause them to be brittle in the long term. It's pretty uncommon but the thought is that now that flouride toothpaste are commonplace, the benefit of flouridated water is also way less. Which changes the calculus.

A not insignificant number of researchers are advocating for the view that flouridating water just isn't worth it anymore and the (slight) risk of flourosis is more significant than the (slight) benefit of decreased dental caries.

userbinator• 1 year ago

Which changes the calculus

Was that intentional? (https://en.wiktionary.org/wiki/dental_calculus for those who didn't get the reference.)

kjkjadksj• 1 year ago

Fluorosis is very common afaik. My dentist told me I have it: slightly whiter patches on my teeth. Then he showed me his own fluorosis. It actually is stronger than the old enamel.

hedora3• 1 year ago

Children are the main group that benefits from fluoride in water because the fluoride helps strengthen teeth as they form. Lack of fluoride increases childhood cavities, leading to decreased academic performance.

This was a real problem in the San Jose school district until recently. They started fluoridation of water in the last ten years, and were the biggest US city that didn’t fluoridate. The evidence of the above is clear according to SJ dentists I have talked to.

somenameforme13• 1 year ago

The National Toxicology Program recently completed a fairly substantial meta study and concluded that "for every 1 mg/L increase in urinary fluoride, there is a decrease of 1.63 IQ points in children.". [1] This is also relevant to OP since it's not just pregnant women at risk from excessive fluoridation but also children. For now it seems that adults are, somewhat oddly, unaffected.

[1] https://ntp.niehs.nih.gov/whatwestudy/assessments/noncancer/...

Speedy2182• 1 year ago

but now it is “overmedicating” a vulnerable fraction of the population.

Makes sense, but the intention also is that many people do not brush their teeth, or at least do not brush them as often as they should, and so fluoride is added to drinking water to compensate so people's teeth don't start to fall out at an alarming rate.

apothegm2• 1 year ago

Sadly, an alarming percentage of Americans don't drink water. I’ve spoken to way too many people who think water tastes wrong because it’s not sweet enough.

kelnos17• 1 year ago

I'm pretty sure that no amount of fluoridated water is going to save you if you do not brush your teeth.

Even if the fluoride somehow manages to overcome all that and prevent you from getting cavities, the gum disease will eventually cause all your teeth to fall out.

mountainriver• 1 year ago

Agree, my biggest issue is often where they source the fluoride and whether they test it. We found out in my (liberal) hometown that they were actually sourcing some derivative which has no human studies.

Given that everyone gets enough in toothpaste I just don’t see the reason to keep doing it, too much can go wrong. It’s kind of a strange mass medication that I’m not sure the government needs to be involved in.

someperson• 1 year ago

What was the derivative?

thayne3• 1 year ago

The advantage of putting it in water is that it ensures all children get it, not just the children whose parents can and do make sure they brush their teeth and go to the dentist.

Whether this is true or not, it's absolutely not why they banned it.

They banned it as part of the culture war. That's 100% of the reason. "The libs" want it, so it must be banned.

robbiep2• 1 year ago

The levels of fluoridation in order to cause difference in IQ as I understand it, from the Chinese studies, suggest that basically the effect if true occurs at around 2x+ the concentration found in supplemented water supplies.

My understanding also is that if you’re a dentist wanting to get rich, move somewhere that has unfluoridated water.

bigmadshoe2• 1 year ago

2x is honestly pretty small. I would expect the amount required to drop IQ to be larger by an order of magnitude or more to conclude that fluoridating water is totally safe.

cortic• 1 year ago

So if your training and double your water intake your basically lowering you IQ? (according to the Chinese studies) I wonder the method this uses.. has anyone looked at dementia rates in high fluoride areas.. Particularly in people with high water intake?

There is also a host of things we use water for from cooking to preserving, distilling and cooling.. i wonder if any of these things could concentrate the fluoride.

Also since fluoride has a lower boiling point any studies tracked what breathing in fluoride gas over long periods cause?

raincole3• 1 year ago

2x is basically no safe margin for something like water. Of course you can question the quality of the study, but if it's actually 2x, fluoride in tap water should be treated like lead pipes.

windexh8er• 1 year ago

The idea is to remove fluoride from water and advise pregnant women to use fluoride-free toothpaste.

What most people don't understand here are the levels of fluoride being ingested. You can very easily remove all fluoride from your water with a relatively cheap RO system. But the recommendation to use "fluoride-free toothpaste" is just plain misinformation.

The reason is that you don't eat toothpaste. And even when adults ingest small amounts of toothpaste, again, the amount of fluoride is basically beyond negligible. Fluoride can both be applied to teeth as a varnish and/or consumed in drinking water. Using a flouride-free toothpaste can oftentimes do more damage than good because of SLS in those alternatives and because those alternatives often have abrasives that do far more harm than good. It's amazing people will recommend a product that may likely be worse because they have no domain expertise. So, yes, people should talk to their Dentist about these things and ask questions of them vs the Internet.

Really the downside to removing fluoride from city water is that low income families will be worse off with respect to dental related issues compared to more well off families that spend time instilling dental hygiene and preventative care for their kids. As you mentioned most people who have decent oral hygiene get enough flouride.

Where we live we have well water. Fluoride in the water isn't a concern, and if it was in our drinking water it generally wouldn't be consumed because of the water filtration anyway.

Dismissing things out of hand like this is a category of stupid in itself.

Look at the current research, listen to people who devoted their careers to studying this, make up your own mind. If you're on HN, then you're qualified enough to at least figure out who the genuine experts are and read what they recommend.

Putting any science-based debate into a "category" to dismiss is turning yourself into one of the stupid people.

edanm• 1 year ago

This is bad advice that no one could possibly follow.

Look at the current research, listen to people who devoted their careers to studying this, make up your own mind.

Do you honestly do this with every single belief you have? Even every single controversial belief? Have you looked, yourself, into whether the world is flat? Whether the 9/11 conspiracy theories are true? Whether crop circles were created by aliens? These are all absurd conspiracy theories, but I assume most people don't know the "up to date" research on any of them, or what people who have "devote their careers" to research them say.

And those are incredibly common and well known to be false theories.

You have to take some things on faith to at least some degree - though to be clear, by "on faith" I mean "on faith of people you trust", which should really start with professional scientists etc. Also, it's totally fine to just say "I have no actual idea" about most things, and just go with what your current understanding of the status-quo position is.

habosa3• 1 year ago

I’m disappointed in the news media fails to mention the cascading effects of dental health. Yes, the primary and direct benefit of fluoride is to have a healthier mouth.

But having a healthy mouth is far from the end goal, imo. If your mouth is full of cavities you’re more likely to build up bacteria that cause downstream effects as serious as heart disease. Also if your mouth is routinely uncomfortable you may gravitate towards soft processed foods and away from healthy whole foods like fresh fruits and vegetables.

I know water is not the only way to get fluoride into people. But these politicians who are trying to take it out of the water are just saying basically “it’s fine, let’s do nothing”. They’re not going to fluoridate the salt. They’re not going to run public health campaigns stressing the importance of regular brushing. They’re just willing to let people’s teeth rot to score points.

It’s disgusting, and no matter how you feel about the water you should be able to see that these people are not on your side.

I would want to see that in anti fluoride campaigns and laws as well, but have not see that happen in the laws and campaigns I have followed.

I think there are lots of kids who don’t know how bad their teeth can get and how that can impact their life in the future (and I mean kids like teens, not like four year olds).

I think there are lots of adults who don’t realize that poor dental health can cause heart failure and worsen basically every chronic condition.

I think there are lots of goobers who don’t realize that there’s no reason that United and Elevance and the rest couldn’t be forced to cover dental care via regulation.

I get your point, but big picture there are a lot of impactful education campaigns that should be possible.

If your mouth is full of cavities you’re more likely to build up bacteria that cause downstream effects as serious as heart disease.

If I went to the store to grab a bottle of water, and they were selling fluoridated water and fluoridated water, I would choose the non-fluoridated water.

I drink tap water now with fluoride so its not like I care strongly, but its a bit weird that many people buy only non-fluoridated water themselves and are confused when other people show a preference for non-fluoridated water in their own taps.

What they're referring to is the fact that very few countries in the rest of the world even consider the possibility of adding fluoride to the water supply. It's basically just the US, Australia, and to a much lesser extent Canada.

It's not a debate everywhere else because adding fluoride to the water is objectively an unusual thing to do that they just... don't. Presumably they get fluoride other ways.

slibhb• 1 year ago

How has the debate been solved by the rest of the world? My understanding is that many countries in Europe don't fluoridate the water supply.

I'm skeptical of results showing IQ loss but I also think fluoridation should be phased out as fluoride toothpaste and mouthwash are now widely available. Banning it seems like the wrong move to me...states should simply decide to continue adding it or not.

lolinder5• 1 year ago

freehorse7• 1 year ago

How has the debate been solved by the rest of the world?

By having official country-level guidelines by the health ministries or similar for people to brush their teeth with toothpaste containing fluoride, and specific guidelines around it for kids, as trivial as it may sound. Along with experts' reviews providing more details on these decisions, and explaining tradeoffs properly.

Fluoride containing toothpaste is the main recommendation, even in places that fluoridate the water (which are the minority). There is not much to add to this apart from refining these guidelines. Eg in the EU where some countries fluoridate water, most don't, there is no huge debate about it overall. Most eu countries that fluoridated the water stopped doing it some point mostly because it was no longer needed in preventing cavities, and prob largely due to logistics/costs than possible risks.

Your second paragraph reflects my personal views on it, too. The "banning" is weird, esp since, according to the article, it comes from people that seem to advocate against use of fluoride in general in toothpastes etc. The discussion should be around best policies to prevent cavities etc, but it does not seem to be around that. I see nothing wrong with local communities deciding if they want to put fluoride or not in their water, based on their own opinions but also general situation. Maybe in some much poorer areas fluoridation of water could be beneficial until some other measures take place, for example.

By not adding fluoride into the tap water and let people choose whether to buy toothpaste with fluoride themselves. a.k.a. the European way.

Adding fluoride into tap water always sounds borderline insane to me. The only benefit is to protect your teeth, which, to me, strongly suggests that the correct approach is to put it into toothpaste or other oral hygiene products instead of water.

Banning its addition is a step beyond — but in Queensland, Australia for example, the state government no longer mandates its inclusion, and thus the local councils are able to set their own policy.

While more than 90 per cent of Australians have access to fluoridated water, that figure is significantly lagging in the sunshine state, where local councils have ultimate authority over whether it is adopted.
A decade after the Newman government handed responsibility for fluoridated drinking water to local governments, 51 out of 77 have opted out. That means about 28 per cent of Queenslanders do not have fluoridated drinking water

How has it been “solved?” There’s just tradeoffs.

There’s evidence that despite widespread availability of fluoride toothpaste and mouthwash, fluoridated drinking water improves dental outcomes at the population level.

There’s also evidence that at high levels (not the normal levels it is added at, but at higher levels which can happen on accident) fluoride may reduce IQ.

I’m ok with either trade off but the “solved” phrasing makes it sound like there is an obviously superior choice.

Meanwhile, back here on Earth-1, there's no right thing, and countries all over the world have "by and large solved" the issue by doing completely different things: https://en.wikipedia.org/wiki/Water_fluoridation_by_country

Water fluoridation is considered very common in the United States, Canada, Ireland, Chile and Australia where over 50% of the population drinks fluoridated water.
Most European countries including Italy, France, Finland, Germany, Sweden, Netherlands, Austria, Poland, Hungary and Switzerland do not fluoridate water.

The missing context here is that the science and established benefits of fluoride aren’t a culture war political football in those countries.

These countries largely publicly recognise the benefits of fluoride, but don’t add it because:

- Some countries opt for intake via supplementation.

- Some have a naturally sufficient supply in drinking water via natural processes.

- Some even need to reduce the abundance of fluoride in their water due to over supply.

While I acknowledge it is not a "solved" issue, I find it bizarre nonetheless, simply because it is so disproportionately low-stakes compared to the amount of controversy around it.

827a• 1 year ago

Once you start trying to cross-reference a public health campaign with something related to peoples' diets, it becomes difficult to make super broad and conclusive statements.

Here's some interesting data (2003 I believe, so pretty old) [1]: It reports that most of Europe, Canada, Australia, and South America experiences cavities at rates higher than the United States. However: Many of these countries have public health care; the US does not. Is the US under-reporting? (I didn't dig much deeper into the underlying data; may not be a relevant concern).

Three things I think are likely to be true: (1) Fluoridated toothpaste is widely available and cheap. (2) Cavity rates are significant even in countries with high rates of fluoridation. (3) Fluoridating the water supply carries with it a non-zero monetary cost. I tend to believe that these three realities, at the very least, justify the conversation as being one we should have. It could be the case that water fluoridation made a ton of sense in a world where people didn't have as much access to fluoridated toothpaste, but nowadays the typical person has hit the limit on what it can do for them, and ingesting more is, at best, doing nothing.

Here's another way I like to think about it: Put the science aside for a second (I know, hard, not ideal, but bear with me). You've got two people who are low income. Person A believes, for their own health and in the expression of their own personal liberties, they want access to fluoride; but the Government is not fluoridating their water. They can spend $5 a month to buy fluoridated toothpaste; possibly not even more expensive than the toothpaste they were already buying. Person B is living in the opposite world: They believe that they do not want to ingest fluoride, but the government is fluoridating their water. They would have to spend many dozens to hundreds of dollars a month buying water bottled somewhere more natural. From a personal liberty and economics perspective: Its pretty clear-cut.

Generally speaking I see fluoridation as a ridiciulous idea, on the grounds that the vast majority of tap water ends up being used for things other than brushing your teeth. It is wasteful and damaging to the environment, that excess flouride that has no business being there ends up in the drain, or the water you use for your plants.

Flouride should be put in the toothpaste. Then people can make a choice on whether they want it, but most importantly, its in the only product that is actually used for brushing teeth

Tade0• 1 year ago

Germany and France don't fluoridate water, but they add fluorine compounds to table salt.

Meanwhile growing up in Poland in the 90s as kids we had these fluoridation sessions in school, for which everyone had to bring their toothbrush and brush their teeth with some kind of sour tasting fluid that contained fluorine.

freehorse7• 1 year ago

Regardless of whether the water is fluoridated or not, the main guideline is "brush your teeth with fluoridated toothpaste". No policy maker elsewhere is pushing narratives against fluoride at large like in the US. These narratives there are even dangerous. One can easily look at dental associations reviews, or official state guidelines and see that more or less they say very similar things. It is very easy to find these policy-informing reviews online.

And regardless of whether the water is fluoridated or not, there is no big debate elsewhere about it, nobody cares that much about it, because all the evidence is that in smaller amounts prob it is does not matter much either way, in the presence of people brushing their teeth. A lot of countries stopped it due to logistic purposes. In netherlands they tried fluoride in the water, a court said they should actually pass a law in order to be able to do it, and they did not even bother with that and dropped it. The fact that some countries may not use fluoride in the water is not due to some deeply-held conviction about how destructive fluoride is for the iq of the kids. In terms of risks of fluoride, fluorosis is what is mostly discussed anyway, and to a degree, unless it is too serious, this may just be an aesthetic issue.

From the perspective of one that watches this craziness from outside, the whole debate is non-sense, and whether some european countries use water fluoridation or not is not very important, it does not cause any heated debate in the EU. The debate in the US is not because the US considers some things that others do not consider. There is no actual truthseeking mentality from the current administration or anybody on this to actually find for sure if fluoride decreases iq, or if fluoride in the water is absolutely essential for dental health even if people are brushing their teeth.

ineedasername• 1 year ago

It's irrational to complain about 'both sides' when only one side is insisting on making it into an issue. I generally just try to disegnage from people as soon as they start freaking out about fluoride/ chemtrails/ vaccinations etc, but people like this frequently treat skepticism as a personal attack. Increasingly they occupy positions of political power (see eg RFK) having acquired them by public displays of conviction rather than any objective criteria.

kelnos17• 1 year ago

No no, in the US we figure out the worst way to do something, and then do that, and invent reasons why the US is unique such that the reasonable solutions that other countries employ just couldn't possibly work here.

(To be fair, though, many [most?] Western countries do not fluoridate their water. The US is actually not doing the common thing here.)

It's honestly not clear if water fluoridation in the US is necessary or all that useful here anymore, as we started doing it when fluoride toothpaste wasn't really a thing. Now pretty much all(?) toothpaste in the US has fluoride in it. If someone can't afford toothpaste, then they probably can't afford regular dental care either, and fluoridated water isn't going to make much of an impact anyway.

Does filtering your water with a whole house filter take the fluoride out?

Because I live in a small township that delivers well water to you tap. It tastes horrible, shortens the life of pipes and appliances, and smells like sulfur.

Every year they mail a flyer that explains how the lead levels are dangerously above the national standard and you should run the tap before you drink from it.

Like, sorry there's nothing we can do about it. =(

ein0p2• 1 year ago

If it's reverse osmosis based, yes. If it's some other kind of filter, likely no, and you should buy a TDS meter and use it, because in all likelihood it's not really filtering anything. I did exactly this. It turned out that my carbon based filter had more TDS than completely unfiltered water from a tap in the garden. RO water, even re-mineralized, had 1/15th the TDS IIRC.

mortos• 1 year ago

TDS is just Total Dissolved Solids. What solids though you don't know and you could be adding carbon while removing others which is likely the case.

Also those dinky little TDS meters don't even measure TDS. They measure electrical conductivity and with a little math they use the EC as a proxy for TDS. It's typically only calibrated to one specific ion, others will be off by some factor. Also keep in mind TDS is expressed in PPM as CaCO3.

alabastervlog2• 1 year ago

Oh man, I used to live in a place like this. You could smell if a restaurant served filtered water (lots filter for the soda machine, to keep mineralization in it down I assume, and use the same water to serve) or straight from the tap, without taking a drink. Like with your nose six inches above the cup, you could smell it. Luckily, almost all served filtered.

Quarrel2• 1 year ago

I looked in to this recently.

Turns out that carbon filters do filter fluoride, but only on the first few X litres of water, where X is in the first 0.01% or so of their expected lifespan. So, they do, but not really usefully in any sense.

My filter that I wanted to know about (so that my kid is getting fluoride) is a 2-stage filter, with the other stage being a particle filter, but fluoride is very small and unaffected.

Your filter might be different of course.

FWIW, in my city, the water has essentially zero fluoride if it isn't added, and it has been a great intervention.

starfezzy• 1 year ago

The people leading the health system are highly credentialed. Moreover, highly credentialed people, in medicine as in all fields, frequently disagree on what studies show, how valid a study is, what it's flaws and limits are, how conclusive it is, and so forth. And the consensus has a long, time honored tradition of being wrong from time to time.

Ultimately, the woo woo people are the ones who rely on someone in a labcoat to tell them whether ingesting government approved (there's your first red flag) synthetic fluoride from industrial byproducts is "necessary".

If it's useful, brushing it onto your teeth and into your gums 56,000 times in your life is probably sufficient, particularly given that we don't know with absolute certainty beyond any shadow of a doubt that the industrial waste options are totally without health consequences. I'll literally just take care of my teeth and cross my fingers over listening to modern medical consensus on a range of topics where I simply trust intuition and common sense more.

efitz4• 1 year ago

It is trivial today to get whatever level of fluoride is recommended for dental health, via toothpaste. So there is no compelling need to fluoridate as there exist viable alternatives to achieve the same that fluoridation is for any other purpose than dental health.

In the USA, dental care is not covered by public insurance, and is an optional add-on to insurance through one’s employer.

So without addressing at all whether fluoridation is effective or safe, there doesn’t seem to be any compelling need to fluoridate public water, and there’s no economic down side for the public if governments choose not to do so.

Given this, why not just leave people alone to make their own choices? If the citizens in a city or state want to fluoridate the public water supply, then do so; if they choose not to, then leave them alone. It’s a free country and voters are grownups; let them choose for themselves.

If you live in a place that chooses the choice you dislike but for some reason fluoridated public water supply is a critical issue for you, either campaign to change it or vote with your feet.

This issue just doesn’t seem important enough to me to spend any effort arguing either way.

I think one thing you're not considering (especially when you say we should vote with our feet) is poverty. It’s true that fluoride toothpaste is widely available, but for people in poverty, of which there are millions in our country, basic hygiene items like toothpaste and a toothbrush aren’t guaranteed. Neither is it guaranteed that everyone has a perfect daily brushing habit like the dentist tells us; there are people who don't brush every day, or even every week.

You talked about dental care not being covered by public insurance — is it not worth considering that some basic level of dental care is already being applied to the country via fluoridation? It's a minimal, cost-effective way to prevent tooth decay at scale. Fluoridated water is one of the few dental protections available to everyone regardless of their income.

kelnos17• 1 year ago

If you're not brushing your teeth, periodontitis will get you; the resulting bone decay will cause your teeth will fall out. But sure, great, the water was fluoridated, so I guess it's nice that those now-missing teeth are free of caries?

I don't believe there's a single person in the USA that's so poor they can't pay $3 for toothpaste every 3 months.

I'm completely sure that any people that don't brush their teeth is just because they are too lazy to even bother.

This trope of justifying everything with "but there are millions of poor people in the USA" is really tiresome.

efirman2• 1 year ago

Your indifference is based on some core assumptions that are false. In reality, 1) Fluoride in water works in addition to fluoride in toothpaste to protect our teeth - rather than two highly concentrated events of reminieralization, fluoriated water reminieralizes the teeth throughout the day. 2) There is a strong economic downside to ceasing fluoridation: Fluoridation saves millions of dollars that otherwise would be spent on dental bills by the public - https://www.healthaffairs.org/doi/abs/10.1377/hlthaff.2016.0... - shows cost savings ratio of twenty dollars for every. dollar invested in reduced treament costs. This remains apt: https://pmc.ncbi.nlm.nih.gov/articles/PMC7164347/ 3) The best way to preserve choice is to maintain fluoridation. People cannot choose to fluoridated their own water system - they can choose to live in unfluoridated areas, use filters that remove fluoride, or otherwise avoid the tap water. 4) Removing fluoridation means acces to fluoride becomes much more difficult and expensive. The reason fluoridation is so cost effective is that it is delivered through the public water system - a community resource. Bottled fluoridated water is more expensive than gasoline. It is also less regulated and less available in the U.S.A.

I think it's worth reminding people of Occam's Razor, and the point of it is: a simple explanation is often better than a complicated one.

The US has had water fluoridation for 65 years, affecting 346 million people. That's a pretty big god damn sample size and long amount of time in which to observe effects. If we still have no proof of significant negative health effects, it's probably not bad for you.

That said: you can always lower the amount of fluoride if it turns out the local area already gets a lot of fluoride from other sources. You don't need to ban it, you can just lower the levels.

So please don't defend this decision by Utah. They're being children.

  Using a prospective Canadian birth cohort, we found that estimated maternal exposure to higher fluoride levels during pregnancy was associated with lower IQ scores in children. This association was supported by converging findings from 2 measures of fluoride exposure during pregnancy. A difference in MUFSG spanning the interquartile range for the entire sample (ie, 0.33 mg/L), which is roughly the difference in MUFSG concentration for pregnant women living in a fluoridated vs a nonfluoridated community, was associated with a 1.5-point IQ decrement among boys. An increment of 0.70 mg/L in MUFSG concentration was associated with a 3-point IQ decrement in boys; about half of the women living in a fluoridated community have a MUFSG equal to or greater than 0.70 mg/L. These results did not change appreciably after controlling for other key exposures such as lead, arsenic, and mercury.

  To our knowledge, this study is the first to estimate fluoride exposure in a large birth cohort receiving optimally fluoridated water. These findings are consistent with that of a Mexican birth cohort study that reported a 6.3 decrement in IQ in preschool-aged children compared with a 4.5 decrement for boys in our study for every 1 mg/L of MUF.10 The findings of the current study are also concordant with ecologic studies that have shown an association between higher levels of fluoride exposure and lower intellectual abilities in children.7,8,26 Collectively, these findings support that fluoride exposure during pregnancy may be associated with neurocognitive deficits.

0xbadcafebee4• 1 year ago

1. IQ is not an objective measurement, it is inherently flawed

2. A 1.5-3 IQ level difference is not noticeable in any practical way. Things like birth order have a more significant impact on IQ.

3. Comparing Canadian children to Mexican is pretty dramatic, like comparing rich kids to poor kids; you will always see a marked difference between the two, in intelligence, in health, in crime, in all sorts of things. Mexican communities often over-fluoridate their water (I know because I grew up in Mexico and my teeth are stained because of it). Again, this is no reason to ban it, just lower it.

This finding is a suggestion of a link, it's not empirical proof. The methods and findings have many questionable aspects. You can always find some paper that suggests something random like vegetables are bad for you or something. One paper does not a water-tight case make.

concordDance5• 1 year ago

The US has had water fluoridation for 65 years, affecting 346 million people. That's a pretty big god damn sample size and long amount of time in which to observe effects. If we still have no proof of significant negative health effects, it's probably not bad for you.

The problem is there will have been a lot of confounders.

E.g. despite huge sample sizes, isolating the cause of the obesity crisis is too hard because so many different things changed at once.

0xbadcafebee4• 1 year ago

Sure, it's not easy to find a smoking gun. That doesn't mean we go all in on whatever we think might be the issue (if there even is an issue).

The answer to the obesity crisis wasn't to ban Pizza. We don't we ban sodas and junk food at schools, which we know would have a positive impact on health. But we do ban fluoride, without proof that it will help? With actually the only scientific proof being that it would be detrimental to remove?

If people's concern is really that it might slightly lower IQ, consider that 1) IQ has been steadily increasing since the 40's, and 2) you can get better IQ by investing in education, something that we do an embarrassing job of already and need to improve on.

The other concern touted is that it might cause cancer. As we well know by now, nearly everything causes cancer.

Banning fluoride is just a move by politicians to take advantage of ignorant scared people to drum up more votes/support. It's like every other action they take to vilify something scary or unknown and then claim victory over the evil thing they purged. This isn't new, either - this clearly partisan stance was being pointed out in the 1950's when it was first being considered for nationwide use.

"After more than 70 years of investigation, there are still questions about how effective water fluoridation is at preventing dental decay and whether the possible risks are worth the benefits. Although water fluoridation undoubtedly did improve the dental health of many children in the 1960s and 1970s, fluoride proponents were perhaps too hasty in declaring that community water fluoridation was the best (or only) solution for dental decay. A less fractious debate might have encouraged a more open discussion in which the possible harms could have been more fully discussed and other options, such as providing fluoridated toothpaste, more fully considered." - https://pmc.ncbi.nlm.nih.gov/articles/PMC4504307/

hayst4ck11• 1 year ago

Putting fluoride in water promotes freedom. That sounds crazy, but let me justify it.

If you are poor you can't go anywhere or buy anything. You're not free if you're poor. If you are sick, you may be confined to a hospital bed or not feel good enough to do anything. If you are sick you're not free.

Putting fluoride in water reduces dental costs and incidence of cavities and therefore tooth infections, particularly among societies poorest. Therefore, due to fluoridation in water some people are less sick and have more money and therefore are more free.

The contrasting view is that putting fluoride in water is literally medicating people without their affirmative consent. It is the government forcing you to take a medication. It is coercive and therefore an attack on your freedom to not take medication. It is the government interfering in your life.

The contrast between positive freedom, the freedom to do something, and negative freedom, the freedom from interference in your life, is the core political argument in America right now. Negative freedom, freedom from government interference, is being promoted by those seeking to weaken the government enough to supplant it. People who are poor and sick are likely unable to stand up for themselves or participate in solidarity against authority. This individual issue is relatively small, but you take 100's of issues like this, and the effect is to create a class of people who aren't able to do anything but be obedient workers.

It seems to be that the battleground is epistemological, but not so much the argument. The difference being that Trump uses 'claims of truth' without any care of how true they are.

Adding fluoride to water was revolutionary in the 1940s, but its benefits have significantly declined since fluoride toothpaste became common in the 1970s.

Sure, some countries and communities may still see benefits from it, but widespread fluoridation doesn't seem necessary in many parts of the world.

The government can give out toothpaste in school, it doesn't need to add things to water.

The inviolability or integrity of one's own body to me is more important than any of this. You have the right to decide what medication to be given to you with informed consent always, or you have no freedom. Otherwise the freedom argument collapses and you stop having reasons to allow abortions, or a bunch of other informed consent situations.

Not when it comes to religion though: the European way (and I feel very much like considering Canadians something like honorary Europeans these days) was forged in painful wars stemming from and fueled by influence of religion on politics, and abuse of religion by politics.

Freedom from.

The American way is completely devoid of that concept. It's all built on that Pilgrim Fathers founding myth and only ever cares about keeping the state from getting in the way of individual beliefs. It's so focused on that part and only that part that even an almost-all-out theocracy would be fine as long as it did not mess with individual beliefs.

Before the bill, your community could either use your own water system, without fluoride, or use the wider system, which has fluoride.

After this bill, your community no longer can use your own water system with fluoride, and the wider system also does not have fluoride.

On a first read, this bill makes the government remove a choice for you, deciding what is good for you.

(I don’t have a horse in this race honestly. Assuming everyone can get toothpaste and toothbrushes, the effect is the same. But the wording of the bill is strange: “may not add fluoride” rather than just “is allowed not to add”.)

This started out as an interesting and fair take until “…enough to supplant it”. Freedom from the government is the original vision and one of the core principles of America assuming that anybody that wants smaller government just wants to supplant it is a massive misunderstanding of most Americans today and certainly the founding principles.

hayst4ck11• 1 year ago

We can read this country's founding philosophy directly:

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.—That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed,—That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.

It's not freedom from government but freedom from tyranny. They believed that governments existed to promote the protection of rights.

It's also restricting the freedom of communities if you ban them from adding fluoride to their water if they like to.

This ban is anti-freedom. (Just like forcing them could be argued to be, even though that's what you argued against.)

So, this ban is arguably reducing freedoms on multiple levels.

pclmulqdq8• 1 year ago

In the political philosophy of the US, the unit whose freedoms matter is the individual, not the community. Freedoms for individuals necessarily come from reducing the freedom of "the community."

kebman6• 1 year ago

Personal freedom ≠ "freedom of communities"—there is no such thing. Freedom applies to individuals, not collectives. When a community makes a decision that affects all its members, that’s democracy, but democracy is not unlimited authority. A majority vote does not grant the right to infringe on individual autonomy, which is why safeguards exist against the tyranny of the majority.

Banning fluoride does not restrict freedom—it prevents government overreach. In contrast, forcing fluoride on everyone would violate personal autonomy. Protecting individual choice is a fundamental principle, backed by real-world safeguards like constitutional rights, judicial review, and bodily autonomy laws. The burden of proof is always on those seeking to impose a policy, not on those defending individual freedom.

Somewhat related, as a teen in the 90s I worked at McDonald’s in The Netherlands.

In The Netherlands, where people drink much more dairy products, especially back in the 90s, people would get plenty of calcium so there was no need to put extra in the bread. But because a hamburger should be a hamburger no matter where you buy it worldwide, the Dutch McDonald’s hamburger bread still had the added calcium

In the UK at least some areas have fluoridated water, despite almost all toothpaste being fluoridated. I suppose it most benefits the minority of people who do not brush their teeth. That benefit has to be balanced[1] against some evidence of risk.

IMO the right fix is better dental hygiene, and a better (less sugary) diet. These are in turn are in part symptomatic of other problems (poverty, long working hours with regards to lack of supervision of children).

Enriched flour is another good example that I was hoping someone would mention*.

It’s worth noting that it’s also slightly different in that processed flour is deficient in thiamin and calcium, so the fortification adds back these nutrients.

On the other hand, processing water to make it potable doesn’t remove fluoride and so fluoridation is not the process of adding back something that was there beforehand.

(In ~100% of restaurant and bakery food; ~90% of grocery food)

Rather than taking choice away, we should be educating people on what the best choice is and letting them make it themselves.

Brush your teeth in the morning and in the evening. Standard dental hygiene - If a person can be an obedient worker they can probably brush their teeth twice a day. If they cant, they have bigger problems to sort out.

rusk4• 1 year ago

This is a fair point, and in modern times, where we have good public health education it makes more sense to take this approach.

However this comes with the weighty caveat that there are public groups that actively agitate against public health campaigns.

On balance I think defluoridation makes sense where you have good public health communication.

Always question whenever a highly educated and thoughtful (and likely wealthy) person like this commenter is telling you poor people are too stupid for their own good and can’t make decisions for themselves.

This is the definition of the principal-agent problem.

Also, “positive freedom” is a hilarious rebranding of dictatorial decision making.

Why not grant more “positive freedom” to the people by deciding exactly what these poor people should do for a living, how they should live, and how they should spend their money. The experts know best, after all.

I’m not even particularly against fluoride in water, but this kind of reasoning is insidious. If the people have voted for representatives that are against it, we should follow the will of the people. This is the definition of democracy.

Excessive fluoride exposure is associated with reduced childhood IQ: https://jamanetwork.com/journals/jamapediatrics/fullarticle/... . Giving poor people (the ones who can't afford to drink bottles water or buy a fancy filter) means to moderate their fluoride intake this risk is creating lower-iq, more obedient workers.

The American view of "freedom" is all messed up. You're "free" if the government doesn't tell you to do stuff. Even if corporations make you do stuff, even if they make you do more stuff the government did, that's somehow "free". And "stuff" somehow only includes trivial things like water fluoridation. No freedom-loving American patriot ever said America isn't free because cops can just murder you if they don't like you.

The contrasting view is that putting fluoride in water is literally medicating people without their affirmative consent.

Is that the contrasting view, or the contrasting view that is preferred, because it is more easily demolished?

The stronger contrasting view isn't that the government is medicating people without their affirmative consent. It's that it's poisoning people, and no amount of consent by laymen to be poisoned would be acceptable.

somenameforme13• 1 year ago

I think his view is much stronger, since the intent is obviously to medicate even if it may indeed be inadvertently poisoning people in practice. So it doesn't assume one truth (poison or not) one way or the other, but still argues that it should be unlawful. While your view is much more narrow and suggests it should only be unlawful because it's poisoning people, which then begs the question of whether it is or not.

audunw• 1 year ago

Fluoride occurs naturally in water, that’s literally how we discovered the effects of fluoride. People in areas where water naturally contained more fluoride had less cavities.

Anything, including water itself, is toxic (not poisonous, but I’m guessing you meant toxic, since fluoride is definitely not poisonous) in high enough doses. So you could say that about ANY mineral we may add to water to adjust its taste or health effects.

I happen to think adding fluoride isn’t worth the effort. But the hysteria against it is also really dumb.

So then, you'd also be against adding folate/folic acid to bread for the same reason?

For those who don't know many countries including the US mandate the inclusion of folic acid in bread and certain other foods to ensure pregnant women get enough. A deficiency of folic acid during pregnancy causes birth defects in infants. https://en.m.wikipedia.org/wiki/Folate

I never heard of that supplement (not a father) and was very surprised to find 80 countries mandate it.

I am against adding anything to a whole population to treat a few, folate included. Here is why. Folate is a known stimulant of some cancers.

https://aacrjournals.org/cebp/article/17/9/2220/169762/Folic...

https://link.springer.com/article/10.1007/s13668-018-0237-y

https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1463-1318....

(And you know that the first line cancer treatments, like methotrexate, are anti-folates.)

So while we are lowering birth defects, are we increasing cancers at the same time? Has this ever been studied?

We are not a homogeneous population.

The same is true for fluoride. Some people have a fluoride allergy:

https://www.aaaai.org/allergist-resources/ask-the-expert/ans...

And while fluoride is known to prevent cavities, it also makes tooth enamel brittle:

https://www.nature.com/articles/s43246-024-00709-8

So I prefer to medicate myself, according to my own needs and my own genetics, thank you.

shireboy• 1 year ago

This take has a few problems: Poor people in the US are capable of using fluoride toothpaste and flossing. At least at homeless shelters at outreach things I’ve been to, toothpaste and toothbrushes are freely available. Your argument hinges on them being incapable on the whole and needing a Benevolent But Superior Intelligence to provide an alternative for them.

Second, it completely ignores any debate over effectiveness or side effects. It could well be that fluoride in water is great for teeth but bad for brains. The objections to fluoride in water I’ve seen are more along those lines. Im not clear the validity of those claims but for example anti fluoride advocates don’t typically object to chlorine in water to kill germs. That seems the core issue- without bias from stakeholders, is the benefit of fluoride proven and the risks disproven? It’s hard to answer because a study needs to span many years and exclude many variables.

And in general I think that is what needs to happen with these type debates. Take them _out_ of the sphere of charged political opinion and focus on getting to the objective truth of risks and benefits, then be transparent. People can handle “here are the known pros and cons and what we think that means” over “there are only pros and no cons and if you disagree you hate poor people”

Except it's not—fluoride in the drinking water concentrations is proven safe and it doesn't affect brains.

Thoroughly scientifically debunked. Repeatedly, over decades.

No, it's not hard to answer, because all those studies have been done and the results were that fluoride is safe.

What needs to stop happening is people ignoring objective reality just because the results happen to align with the other "team's" position on something.

hayst4ck11• 1 year ago

Truth and even the idea that there is objective truth is a fundamentally political concept. Authoritarians are opposed to the idea of objective truth because objective truth gives a person a foundation on which to criticize and dissent from those in power. Truth is threatening to authoritarians. Truth is an alternative source of legitimacy.

We are experiencing an assault on objective truth in the US in order to get scientific institutions to submit to political authority rather than the authority of reason.

So I agree with you, it is policy that should not be handled by politicians but by experts, which none of us are. Unfortunately science is being politicized.

The problem is science challenges those who derive power from means other than reason.

Defending scientific consensus is seen as an equally political act as denying it.

This is absolutely not a substitute for fluoride in drinking water, which is most important for kids. When your teeth are forming below the gumline, the fluoride you ingest strengthens them. Brushing gums with fluoride doesn’t help.

verall2• 1 year ago

Your argument hinges on them being incapable on the whole and needing a Benevolent But Superior Intelligence to provide an alternative for them.

This is so incurious. Obviously most people, poor or not, have access to fluoridated toothpaste and toothbrushes, and can brush.

Yet OP cites data (not explicitly, but you can start here: https://pmc.ncbi.nlm.nih.gov/articles/PMC6974062/, there are many like it).

Fluoridated water makes the most impact on poor and undeserved communities: Why?

Is it because poor people are less capable of brushing or have less access to fluoridated toothpaste?

Is it because poor people are poor because they have poor self control, which prevents them from regular brushing?

Does it matter? Nothing hinges on them being incapable at all - your conjecture can be as uncharitable - poor people are dirty and incapable - or charitable - poor people have less money and time to seek dental care, have higher rates of untreated mental and physical illness i.e. ADHD, disabilities that interrupt daily tooth-brushing routine - as you want.

But the result is still that if we want children from poor families to have less cavities by the time they reach adulthood - we should fluoridate the water! If you trust the western medical establishment, it's broadly safe. If you don't, then none of the evidence above matters to you anyways.

yalogin• 1 year ago

See this is the problem today. Just because some one doesn’t know doesn’t make it non existent. We have decades of studies and evidence that fluoride is good and has no side effects, but the detractors ignore all of it and keep nullifying all that knowledge. Now they are successful too. In a society where everyone wants the whole boat to rise up, we need a certain amount of honesty and integrity and sadly these arguments don’t have it

Putting fluoride in water promotes freedom. That sounds crazy, but let me justify it.
If you are poor you can't go anywhere or buy anything. You're not free if you're poor. If you are sick, you may be confined to a hospital bed or not feel good enough to do anything. If you are sick you're not free.

or, you know, you could avoid the problem in the first place and allow "even poors" to go somewhere or buy something... at least base items, and medicines...

this way they could afford dental costs, and you could spare the need to add fluoride in the water

I think it's a reductionist word game to reduce everything to a single dimension ("freedom") and then say "I think my policy is better, and since everything can reduce to a single variable it means there is more freedom".

If a right-wing voter thinks banning gay marriage is good for society, it is also positive freedom? If your counter-argument is "no, because while it would be positive freedom if it was good for society, it's not" then maybe I'm just disareeing on your terminology, but I suspect you would say "heck no, telling people what they can't do is not freedom, that's an abuse of the English language as well as being bad for society".

Governments exist to take away some freedoms, it's the whole point of them. People vote for governmets to take away freedoms (with laws and taxes) and get things like public services, justice systems and infrastructure in return. Ideally, they lean towards things that give you a lot of bang for your buck (like flourine), because taking away freedom is not good for creating a dynamic society, and they should be accountable to voters.

Just say that anyone who objects is an anarchist if you want to take the moral high ground from the right in terms they understand.

brigandish3• 1 year ago

The contrast between positive freedom, the freedom to do something, and negative freedom, the freedom from interference in your life, is the core political argument in America right now.

True.

Negative freedom, freedom from government interference, is being promoted by those seeking to weaken the government enough to supplant it.

Tenuous. Then again, like you, all of my political opponents are either stupid or evil or both.

People who are poor and sick are likely unable to stand up for themselves or participate in solidarity against authority.

Contentious. Sometimes this is true, sometimes it is not - giving negative liberty rights (e.g. first amendment speech protections) to individuals has proven an incredibly effective tool to protect the individual against the state. Not perfect, but incredibly effective all the same.

This individual issue is relatively small, but you take 100's of issues like this, and the effect is to create a class of people who aren't able to do anything but be obedient workers.

Any supporter of negative liberty (i.e. someone who is for small government) would tell you, that is what government does, which is a big reason why they want small government.

So, Finland gave fluoride a shot in a few cities back in the '60s through the '90s, but they didn’t see much point to it and dropped it. Now, some spots there are even filtering it out of the water. You can still get it in toothpaste and mouthwash, though.

There’s this study I read that says the top five countries for dental health are Denmark, Germany, Finland, Sweden, and the UK. The US? It’s lagging at ninth. Funny thing is, out of those top five, only the UK messes with fluoride in their water, and even then, it’s just for like 5% of folks.

Honestly, it kinda feels like skipping the fluoride in water might be the smarter move.

There’s a tendency to backwards rationalize anything that is established in the US, that comes from a place of identity.

The current shape of the US is already the best and people consider it a part of who they are, so suggesting a course correction may be seen as both wrong think and a personal attack and wanting radical change would be outright treason.

There’s an array of standard stencils for defense against change: this is the only thing that can work here, this is the only thing that guarantees freedom, this is actually not that bad, I actually prefer it like this, anything else would be expensive/impossible/unamerican.

It’s not even unique to the US, but who cares about other places.

Fluoride in toothpaste already covers most people today. So, if there are legitimate concerns about adding it to the water supply due to fluorosis, even if those concerns are small, removing it seems reasonable to me.

abxyz• 1 year ago

You're misattributing: the U.S. has a perfect white teeth culture that doesn't exist elsewhere. Many people outside of the U.S. have healthier but uglier teeth. Fluoride isn't the reason for good/bad teeth inside/outside of the U.S, it's cultural. Many places outside of the U.S. do put fluoride in their water (nationally or regionally) and have "bad" teeth (e.g: England).

AndrewSwift2• 1 year ago

bobbylarrybobby• 1 year ago

While tooth whiteness in the US is often divorced from tooth health, fluoride does add a yellowish tint to your teeth, so the healthiest teeth — those imbued with fluoride — are slightly yellow. (In fact when they first decided to add fluoride to water, one of the questions was just how much they could add before your teeth would turn completely yellow. Health-wise the yellowing was fine, but it was obviously visually unappealing.) Ugly teeth may be due to poor/lack of orthodontia, but it's probably not due to better dental care.

lukan2• 1 year ago

But flakes of gold are not associated with a lower IQ in children.

"The NTP monograph concluded, with moderate confidence, that higher levels of fluoride exposure, such as drinking water containing more than 1.5 milligrams of fluoride per liter, are associated with lower IQ in children."

https://ntp.niehs.nih.gov/whatwestudy/assessments/noncancer/...

So it is also not clear, if the lower concentration typically found also has this effect.

"It is important to note that there were insufficient data to determine if the low fluoride level of 0.7 mg/L currently recommended for U.S. community water supplies has a negative effect on children’s IQ."

But the solution of just using (cheap) Fluor in toothpaste to apply the Flour where it should go - to the teeth and not the stomach, sounds smarter to me.

kelnos17• 1 year ago

So in other words, 0.7mg/L fluoridated water is also not associated with lower IQ in children. That study did not prove it safe, but it did prove it unsafe, either.

Preventing cavities is far more effective with topical application of fluoride on the teeth, rather than ingestion.

I personally don’t buy the passive health benefit. Even if it’s true, there’s no proof that fluoridated water is superior to topical application.

Not to mention that if we’re going to just roll over and accept stuff in the water for public health reasons, what really should be added are more vitamins, not fluoride. In particular vitamin D

For children developing their “adult teeth” fluoride ingestion strengthens those teeth before they pop out. Topical has no effect obviously since they haven’t surfaced yet.

ReptileMan2• 1 year ago

Fluorinating all of the water just to deliver some milligrams to the teeth is incredibly inefficient. Especially when less and less of the stuff people people drink comes out of the tap.

We have toothpastes and fluorinated mouthwash that both get the job done.

Probably there are some people that are unable to afford those and unaware how to use them, but probably are tiny percentage of the state population, especially with the cult of teeth care that the US has.

I also see the fortified flours as example (or iodine in salt) - but the US is different now than in the 30s. The US diet is more varied. Very few people get 80% of their calories from a single starchy staple so developing a severe deficiency of something requires some serious effort from the persons affected.

So who is this policy of fluorination for - the people that are too poor to afford toothpaste, but still have access to municipality treated water and don't drink copious amounts of soda or bottled drinks.

A dentist once recommended Xylitol gum to me for this purpose. It's been too long to remember the details, but you can do some research on it.

Cynical take: Now that studies have shown that bottled water is loaded with nanoplastics, upper class people want to start drinking tap water again. Now suddenly states don't want fluoride in the tap water...

Taking compounds of the most electronegative element, and treating people with them systemically—drink it, bathe in it, cook with it—when local administration directly to the teeth is cheap, easy, & effective makes no sense at all.

Meanwhile, mining industries produce—and must dispose of—a steady stream of fluoride compounds that would otherwise have to be dealt with as toxic waste (i.e. very expensive) if they ever lost the green light to dump them into the water supply.

https://en.wikipedia.org/wiki/Harold_Hodge

or per Google:

Three chemicals are used to fluoridate drinking water in the U.S: sodium fluoride (NaF); sodium fluorosilicate (Na2SiF6); and fluorosilicic acid (H2SiF6). Fluorosilicic acid is a byproduct of the manufacture of phosphate fertilizer.

I hope they will ban it everywhere. If my pineal gland gets any more calcified, I'll probably end up getting a full-chest tattoo and dye my hair pink.

“Do you realize that in addition to fluoridating water, why, there are studies underway to fluoridate salt, flour, fruit juices, soup, sugar, milk, ice cream? Ice cream, Mandrake? Children’s ice cream!...You know when fluoridation began?...1946. 1946, Mandrake. How does that coincide with your post-war Commie conspiracy, huh? It’s incredibly obvious, isn’t it? A foreign substance is introduced into our precious bodily fluids without the knowledge of the individual, and certainly without any choice. That’s the way your hard-core Commie works. I first became aware of it, Mandrake, during the physical act of love...Yes, a profound sense of fatigue, a feeling of emptiness followed. Luckily I-I was able to interpret these feelings correctly. Loss of essence. I can assure you it has not recurred, Mandrake. Women, er, women sense my power, and they seek the life essence. I do not avoid women, Mandrake...but I do deny them my essence.”

swasheck4• 1 year ago

the debate in this thread is a reflection of the politico-scientific standing of the united states. it seems as though fluoridated water has come to be treated as a synechdoche for the role of science (and public health) in society. both sides are trying in earnest to defend their meta-position (“freedom” vs “society”) but slip into logic errors (usually cherry picking and straw man). i think this is because of the context switching between the part (fluoridation) and the whole (freedom/society).

The fluoride toothpaste they recommend is far more effective in fighting cavities, but ok

That’s going to go poorly. A Canadian city removed fluoride from water in 2011 and reversed that decision 10 years later. There’s hard data on the effects and they’re not good [0].

Unfortunately, hard data is not acceptable. This is how it works for the current administration:

All previous data is ignored because of political reasons.

Teeth to slowly rot in heads.

Sometime in the 2030s, local voters will notice they have very bad teeth.

Locals will debate if adding fluoride is going to make teeth great again.

All the evidence in that article is based on what a politician thinks. "And I think another meta study came out also".

The actual high quality evidence shows that water fluorination has minimal impact on tooth health in 2025: https://www.cochrane.org/news/water-fluoridation-less-effect...

agentultra2• 1 year ago

I was thinking of this study:

https://onlinelibrary.wiley.com/doi/full/10.1111/cdoe.12215

Perhaps more could be done. The situation is complex because of several compounding factors for sure. There are European countries that have no water fluoridation and better oral health outcomes than in North America.

Regardless, there’s 10 years where a city in North America turned off water fluoridation and we have results of that decision to study.

bko2• 1 year ago

I don't think it's about hard data and optimization of health, but rather bodily autonomy.

I'm sure there are plenty of chemicals that could be forcibly put in the drinking supply that, based on current scient, would be beneficial for the public. But I would still be skeptical. Sell me these substances in my food or toothpaste, but don't put it in my drinking water by default.

It's also worth noting about 3% of western Europe has fluorinated so let's not pretend like this is unprecedented

fzeroracer5• 1 year ago

Many places in Europe have high levels of fluoride in their water naturally. In fact many of them are likely getting far too much fluoride.

Also realistically, if people cared about bodily autonomy cars would've been banned immediately thanks to the amount of particulates and local pollution produced causing far more adverse health effects.

cherry_tree• 1 year ago

Is one due the right to potable water at a tap at their home? Or is purified water a service offered by the government as one source of many available to the us population?

Are you not allowed to pay for bottled water instead of paying your local utility for drinking water?

The bodily autonomy argument seems bad to me because you are buying water from the government when you could buy water from any other source instead.

Is the argument that the government water is too convenient and so it should be unfiltered? Who is to say that filtering out poop is not infringing on my right to consume unfiltered water?

somenameforme13• 1 year ago

The study [1] that's based on seems pretty typical, and is precisely what drives skepticism towards these policies. The differences for permanent teeth were not significant. The paper claimed this may be because "7-year-olds have not had the time to accumulate enough permanent dentition caries experience for differences to have become apparent." The differences in temporary teeth had a deft (decay, extracted, filled teeth) of 66.1% in Calgary (no fluoride) and 54.3% in Edmonton (fluoridated).

So you're looking at a small positive improvements in dental outcomes, for what may be a permanent decline to IQ. That's obviously not a trade I think anybody would make, so the real issue is not whether or not it improves dental outcomes but whether it's having measurable effects on IQ as we have seen in other studies. [2] I don't understand why a study operating in good faith wouldn't also pursue this question in unison, or in fact as the primary question. I think relatively few people outright doubt the dental benefits of fluoride, but rather are concerned about the cost we may pay for such.

The most ridiculous part is that we have an alternative way to apply fluoride without intaking it. It's called toothpaste. But for some reason people act like Utah is banning vaccine.

almog3• 1 year ago

In the 2nd study that shows correlation between fluoride and lower IQ in children, the water had twice as much fluoride as the recommended amount in the US (1.5 mg/L vs 0.7 mg/L).

zamalek• 1 year ago

Fluoride was introduced late enough in Zimbabwe that many of my childhood adults easily remembered life before it. There were many horror stories about the general state of teeth prior.

That being said, your dentist can apply fluoride to your teeth (boggles the mind why insurance won't pay the $50), and flouride toothpaste is still much more common than not. It's probably not needed in the water supply for dental purposes.

That being said, what are the other fringe benefits: such as microbe control?

grepfru_it• 1 year ago

The city of Houston has stopped adding fluoride to water but allows natural fluoride levels to exist[0]. We are going on year 6 and the only thing we have noticed is harder water.

There is probably more nuance to both stories tho.

The studies in 20-30 years of the consequences of this will be fun.

noefingway• 1 year ago

What I find fascinating about this debate is that only municipalities/cities add fluoride to water. If you are on well water, no fluoride. So any studies comparing the incidence of tooth decay between populations that are on well water and those that are on fluoridated city water?

I get that this was a great public health benefit before fluoride in toothpaste became widely available but is this still the case? Couldn't it be argued that most of the benefit comes from brushing your teeth?

cma2• 1 year ago

Flouride incorporates into the tooth structure in developing teeth before they emerge, I'm not sure how effective that is but it is different than the more topical protection.

Tea has enormous amounts of flouride depending on where it is grown and they aren't banning that yet.

iterance• 1 year ago

For what it's worth, very few locations and processing styles result in significant doses of fluoride in tea. Within the United States, these types of tea are not typically consumed. For example, Tibetan brick tea is consistently high in fluoride, to the extent that fluorosis is actually somewhat common in certain regions. But it's a bit tricky to even buy a brick (meant for consumption) within the US. Bagged tea, more commonly available, has to be drunk regularly in very significant volumes to have a deleterious effect.

Put another way, for issues to rise to the level of public policy, they have to affect a meaningful number of people in a region. In the US, tea-induced fluorisis is extremely rare.

zackmorris• 1 year ago

Middle-aged human LLM here.

This debate is about evidence vs policy:

* Evidence: fluoride displaces iodine and other halogens, which disrupts thyroid function and possibly negatively impacts other organs and bones.

* Policy: wealth inequality in the US has created a situation where the poor struggle to such an extent that they don't have access to basic health services like fluoride treatments at the dentist every 6 months, while the rich have grown so greedy that they don't want to pay a fraction of a percent of their taxes for preventative care for children and the impoverished so they instead tolerate slightly more expensive fluoridated tap water at the expense of everyone's health.

This comment is about my subjective experience with a sample size of 1, meaning that it doesn't apply to you or the public:

* My father is a dentist and gave me fluoride treatments every 6 months while I was growing up in Idaho. I was raised mostly on well water which isn't fluoridated. I have never had a cavity, despite not going to the dentist for the decade of my 20s while he lived away from me. My thyroid function is not as high as I would like after a lifetime of acute stress from struggle, multiple insults to the body, drinking fluoridated water after the age of 18, and being exposed to radioactive iodine at 80 times the US drinking water standard for perhaps 1 year after the Fukushima Daiichi nuclear disaster (which potentially either gave me a lifetime dose or was insignificant).

This solution is as evidence-based and equitable as I can come up with:

* We should remove fluoride from drinking water and reimburse all dentists for free 6 month fluoride treatments of the general public, which represents some nominal fee of perhaps $15-$20 per person annually (probably less) which is not materially significant to the federal budget of roughly $15-20,000 per person annually.

This take is my personal subjective opinion followed by objective evidence supporting my claims:

* I don't think highly of Robert Kennedy Jr's health initiatives, because they don't ethically weigh evidence and policy, and we don't have enough epidemiological studies to predict outcomes. So they will certainly cause unintended consequences. That said, I believe there is merit to his concerns. So a way forward is not to be anti-vax for example, but to recognize that there are dozens of types of vaccines and to prioritize vaccines for illnesses like polio that have a high risk of negatively impacting quality of life. Health experts should continue advising elected officials on policy decisions. Public health is not a domain that can be left in the trust of individuals acting unilaterally. So removing fluoride from water without providing state or federal funding for fluoride treatments every 6 months will most likely negatively impact public health.

Strangely, I never see the people demanding we ban fluoride also demand we ban cars, considering the amount of particulates and rubber wheels we inhale as a result of policy, road design and car design. And I can almost guarantee you that's resulting in an actual meaningful drop in IQ and health outcomes as opposed to fluoridating water.

But I guess freedom to pollute matters more than bodily autonomy in terms of mental priority.

The solution to ALL of this is a very simple randomised controlled trial. Identify 1000 pregnant women in a fluorinated area, give half of them free unfluorinated bottled water for their pregnancy and first 2 years of babies life, and let the other half drink tap water, then measure all of the kids’ iqs at 5 years.

Sadly noone has done this because the topic is too radioactive for most researchers or science funders to touch.

Water fluoridation conspiracy theories were a thing old enough to be a plot point in 1964 Dr. Strangelove. When there's an entire grift or political career to be a "Fluoride truther", it's really hard to take seriously any of these claims. Given it's naturally occurring and often in higher doses and there'd been so much time to control for any side effects, I'd need extraordinary evidence to be swayed on this.

  GENERAL JACK D. RIPPER: Mandrake, do you realize that in addition to fluoridating water, why, there are studies underway to fluoridate salt, flour, fruit juices, soup, sugar, milk... ice cream. Ice cream, Mandrake, children's ice cream.

  GROUP CAPT. LIONEL MANDRAKE: Lord, Jack.

  GENERAL JACK D. RIPPER: You know when fluoridation first began?

  GROUP CAPT. LIONEL MANDRAKE: I... no, no. I don't, Jack.

  GENERAL JACK D. RIPPER: Nineteen hundred and forty-six. 1946, Mandrake. How does that coincide with your post-war Commie conspiracy, huh? It's incredibly obvious, isn't it? A foreign substance is introduced into our precious bodily fluids without the knowledge of the individual. Certainly without any choice. That's the way your hard-core Commie works.

acidmath• 1 year ago

Pretty much everyone I personally know, this in part to coming from a family of relative affluence in highly liberal areas, has religiously filtered their water to keep additives (such as fluoride) from going into their bodies. This same crowd has savvy towards dental hygiene, they're all into oil pulling, and brushing with Fennel oil and all that. Eliminating yeast (which is fungus, not bacteria) from the mouth prevents the biofilm that creates the necessary conditions for dental cavities.

Even the poorest Americans can afford coconut oil and Fennel oil.

There's no reason to drink that shit (fluoride), there's no reason to brush with it either.

All i know is my parents generation grew up without it and saw they dentists for fillings, every year, for years. Seemed like their childhoods played a part here because half their life they had toothpaste at the same rates as me.

I on the other then havnt seen a dentist in 25yrs, have no fillings after 40, and wouldnt say i brush my teeth twice a day, everyday, as recommended. I do however consume water tainted with fluoride.

So maybe there are more factors at play here then simply washing our teeth. I cant fathom how dirty our parents generations teeth must have been before toothpaste to result in the amount of fillings they have compared to people my age (unless your a meth head).

Utah becomes first US state to ban fluoride in its water
