Fluoridated water doesn’t seem to make a difference on cavities. It does have neurological effects. It’s simply not acutely fatal. It’s already in our toothpaste. We don’t need it in our municipal water supply and the majority of developed countries don’t.

It’s an opinion piece by a geneticist (so not a chemist or biologist or a field that could be related) and she ignores all the direct evidence that every city and county that added fluoride started having fewer cavities than neighboring areas that hadn’t yet added it.

She then further points out that it only causes health issues in much higher concentrations than what the US was getting our water supply up to. You know, like literally anything that you get too much of is bad for you. You can literally die from drinking too much plain water. Too much of anything will kill you.

Keep in mind that they listed Canada as having non-flouride water, presumably based on the sole criteria that it’s not a national requirement. The split between communities with and without flouride in their water varies wildly by province.

The source is not as reputable as it appears. The article in question is not from the Harvard School of Dental Medicine, and in fact was condemned by the HSDM. The actual dental experts at Harvard requested a formal retraction of the article: “Based on the significant flaws in the magazine article, we respectfully request that the article be rescinded, and a correction be published to clarify any misleading information that was provided.”

That’s because it’s just a bs opinion piece by some geneticist. There’s loads of very conclusive evidence and testing proving that it reduces cavities. Also, this geneticist points out that it only causes problems in doses far higher than what fluoridated tap water gets brought up to.

It’s actually exactly in line with what the link above says.

In June 2015, the Cochrane Collaboration—a global independent network of researchers and health care professionals known for rigorous scientific reviews of public health policies—published an analysis of 20 key studies on water fluoridation. They found that while water fluoridation is effective at reducing tooth decay among children, “no studies that aimed to determine the effectiveness of water fluoridation for preventing caries [cavities] in adults met the review’s inclusion criteria.”

In other words, water fluoridation might not make much difference for adults, but it can for children.

This is a disingenuous take. This is a cherry-picked article that does not come to the conclusion you draw here. You also state “It does have neurological effects” but leave out the most important piece of information for that to be true: high doses.

Your link is more or less an opinion piece from a geneticist, so this isn’t even her field of study.

All her health issues she points out are for fluoride concentrations over triple the amount that tap water is brought up to.

The reason it’s usage spread across the country was because while the entire country had access to things such as fluoridated toothpaste, counties and cities that started fluoridation of their water supplies consistently had fewer cavities than areas that didn’t fluoridate the water. This alone outlines the glaringly obvious flaw in her argument.

Further still, while the US adds fluoride to the tap water in a concentration to reach 0.5mg to 0.7mg per liter of water (a couple drops per 50 gallons), natural drinking water for over 20% of the world is in concentrations well over that (to be clear, being well over that can cause health issues. Too much of anything can cause health issues.)

In other words, there is no evidence that this low concentration of fluoride causes health issues. There is loads of direct evidence that it reduces cavities. Plus, this woman from your opinion piece is talking out of her field. Not to mention that 21% of the world’s drinking water supply naturally already falls within the recommended range of what the US takes theirs up to. It’s just that most of the US water supply naturally falls below that amount.

Thank you for the link. It’s worth mentioning that there are response letters to the publication you linked from other experts, the majority of which are critical and point out misinterpretations and omissions by the author. It’s always good to question, but in this instance it looks like the consensus amongst experts evaluating that publication is still that fluoridation is safe and improves dental health. The response letters can be read here.

Edit to add: The responses include a letter from the dean of the Harvard School of Dental Medicine stating that the publication is deeply flawed and requesting a retraction, and a similar condemnation from the students of the Harvard School of Dental Medicine. The article was given greater weight by being linked to Harvard, but in fact Harvard dental experts explicitly disagree.

Interesting. The article doesn’t actually say that fluoridation in water supplies is dangerous but that some researchers are questioning. Generally code for lack of scientific evidence. It also finds that early studies may have had a flawed basis (pretty much all early studies have been found wanting by later scientists) but doesn’t refute the results.The study mentioned in the article talks about high levels of fluoridation which I assume is in lab tests however these levels are not the case in water supplies.

The correct way forward is more actual science based studies.

Toxicologist here. I think that take is dishonest or dumb.

Taking a lethal dose is almost never the concern with any substance in our drinking water.

Hormones, heavy metals, persistent organic chemicals, ammonia are all in our drinking water. But for all of them we can’t drink enough water to die from a high dose.

Some of them still have a large effect on our bodies.

It’s about the longterm effects. Which we need longterm studies to learn about. That makes them harder to study.

Still doesn’t mean flouride does anything bad longerm. But the argument is bad.

It’s so funny I was just having a similar conversation about neurotoxic venomous animals in another thread. Lethality is an obviously concerning threshold, but there are substances out there that can easily destroy your quality of life and livelihood that never reach the concern of being lethal.

I think for mostly rational people concerned about fluoride in their water is that it was a public health decision made with little to no actual science proving it’s safety or efficacy when it was first decided that they were going to add it to the public water supply. The proposed benefits of it weren’t even supported by scientific evidence, it was just supposed that exposure to sodium fluoride could potentially reduce tooth decay for some.

Personally, I’ve suffered from the cosmetic damage of dental fluorosis, and I’m not necessarily thrilled about fluoride. But I have way more issues with public mandates founded on pseudoscience than I am with sodium fluoride. Especially now that we can see evidence that for some people fluoride can be especially beneficial.

So what was wrong with giving people the option of using fluoride toothpaste or mouthwashes… Why did it have to go into the public water supply?

In our area, the only water supply WITH Fluoride serves an area with a median HOUSEHOLD income of less than $40k with more than 25% living below the poverty line. For communities like these the fluoride is critical because there will be a lot of children that don’t have access to fluoride supplements, or regular care from a pediatric (or regular) dentist.

Fluoride does have long term effects though once you consider fluoride exposure through all sources like diet, which is mostly due to fluoride from water ending up in farmland. Tradesmen alone regularly exceed the upper limits due to high water consumption in hotter seasons

Are you sure fluoride doesn’t? It does accumulate in the soil, building up in crops. Considering fluoride exposure from all sources, many people are above upper safe limits, even from tea drinking alone

I don’t think fluoride should be added to water as it just pollutes the environment, where 99.99% of water isn’t coming in contact with teeth

You can get even more granular than that. CDC maintains a list of water systems and whether or not they add fluoride. CDC My Water System. To give you an idea of how granular that is, there are 78 different water systems in my county alone. For most of my life I assumed we had fluoridated water but apparently only 1/78 of our water systems are.

The question to me is - do we even have to fluoridate water and is this really the best approach?

For example, most European countries do not commonly use fluoride in their water supply, and everyone’s just fine! No extra cavities, no special health risks. People commonly drink tap water and do not care about potential for any adverse effects, because it’s just that - clean water. And for any teeth-related issues, you already have your toothpaste providing more than enough fluorine.

It depends if you believe in the apocryphal story behind fluoridation. This is a story that justifies the state and it’s right of medical intervention into your life with the need of your informed consent.

These types of stories are designed to justify the right to act of an entity/egregor using the least objectionnable scenario possible. Once this precedent is established it can built upon to justify other actions in other scenarios. All the other unobjectionnable things done to you or in your name

  • Water fluoridation reaches over 13 million Europeans through programs in England, Ireland, Poland, Serbia and Spain

  • Children in deprived areas benefit most from water fluoridation according to 2018 English health agency report

  • Over 70 million Europeans receive fluoridated salt through programs in Austria, France, Germany, Switzerland and other countries. Salt fluoridation is recommended when water fluoridation is not feasible

  • European Academy of Pediatric Dentistry endorses water fluoridation as “core component of oral health policy”

  • Fluoridated milk programs have operated in Bulgaria, England, Hungary, Russia and Scotland

  • Several European countries provide free or subsidized fluoride treatments through national healthcare:

    • Sweden: free dental care through age 23
    • Denmark: free dental care until age 18
    • Finland: public dental clinic access for all legal residents
  • Scandinavian schools offer fluoride varnish, tablets and rinse programs

  • Some regions in Europe have naturally fluoridated water, such as parts of Italy. Italian health officials support water fluoridation but don’t implement additional programs due to naturally optimal fluoride levels in some areas

https://www.cdc.gov/fluoridation/about/statement-on-the-evidence-supporting-the-safety-and-effectiveness-of-community-water-fluoridation.html

  • Evidence shows that water fluoridation prevents tooth decay by providing frequent and consistent contact with low levels of fluoride, ultimately reducing tooth decay by about 25% in children and adults.

  • evidence shows that schoolchildren living in communities where water is fluoridated have, on average, 2.25 fewer decayed teeth compared to similar children not living in fluoridated communities.

  • A study to compare costs associated with community water fluoridation with treatment savings achieved through reduced tooth decay, which included 172 public water systems, each serving populations of 1,000 individuals or more, found that 1 year of exposure to fluoridated water yielded an average savings of $60 per person when the lifetime costs of maintaining a restoration were included.

  • Analyses of Medicaid claims data in 3 other states (Louisiana, New York, and Texas), have also found that children living in fluoridated communities have lower caries related treatment costs than do similar children living in non-fluoridated communities; the difference in annual per child treatment costs ranged from $28 to $67.

https://pmc.ncbi.nlm.nih.gov/articles/PMC9544072/

  • community water fluoridation continues to decrease cavities by 25% at the population level.

  • Even with fluoridated products such as toothpaste and mouth rinses, this public health practice can reduce an additional 25% of tooth decay in children and adults

  • In 1945, Grand Rapids, Michigan became the first U.S. city to fluoridate its public water supply. Five years later, Grand Rapids schoolchildren were found to have significantly fewer cavities than children from the control community of Muskegon, and additional water districts, including Muskegon began fluoridating and seeing similar results

  • Studies have shown that populations from lower socioeconomic groups within fluoridated communities have less tooth decay when compared to peers in nonfluoridated communities

  • The cost of a lifetime of water fluoridation for one person is less than the cost of one filling
