    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.

        lead poisoning becomes evident pretty early though doesn’t it? (With respect to kids)

        I would think that the ratio of persistent exposure to unsafe level has got to be easily higher in cases like Flint than any fluoride-in-the-water usage. Just speculation on my part.

        What measures are taken to avoid screwing up the dosage, anyone know? Maybe predilute so that an oops requires multiple buckets instead of vials?

          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

            It doesn’t. This is high-school chemistry.

            Fluoride only “accumulates” up to the peak concentration of the environment (no further) on places where it is removed from contact with that environment.

            You can only accumulate fluoride in the soil if you keep adding it and there is almost no rain to wash it away.

        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. I only checked when we had kids and I needed to know whether or not I needed to give them Fluoride Drops.

      This. How can we be completely certain that something isn’t damaging over the long term. I’m not anti fluoride, but healthy debate and scepticism is a good thing, especially when we’re all forced to consume a substance with the only alternative being dehydration and death. People need to be free to make their own choices.

      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?

          Yeah that proves my point entirely.

          In 1945 they fluoridated the first public water supply.

          In 1979 the first published research began to appear to show how fluoride might be able to remineralize dental enamel.

            In 1945, Grand Rapids became the first city in the world to fluoridate its drinking water.The Grand Rapids water fluoridation study was originally sponsored by the U.S. Surgeon General, but was taken over by the NIDR shortly after the Institute’s inception in 1948. During the 15-year project, researchers monitored the rate of tooth decay among Grand Rapids’ almost 30,000 schoolchildren. After just 11 years, Dean- who was now director of the NIDR-announced an amazing finding. The caries rate among Grand Rapids children born after fluoride was added to the water supply dropped more than 60 percent. This finding, considering the thousands of participants in the study, amounted to a giant scientific breakthrough that promised to revolutionize dental care, making tooth decay for the first time in history a preventable disease for most people.

                So the person above may think they’re so clever, or whoever fed them that factoid may think that. Notice the claim is remineralization. Maybe that’s true, it may be that a study first showed that in 1975 and that’s not contradicted by your link but that is a non sequitur. It’s not what we’re talking about, it’s not a good faith argument.

        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

    For what’s it worth, in my country (Netherlands), we don’t add fluoride to our tap water anymore since the early 70s. We just have it in our toothpaste (though you can also get fluoride free toothpaste for those who don’t want it).

    Sure there’s still traces of fluoride in our water, as it appears in nature. But it’s not artificially added by our water companies.

    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.

      • 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

    The fluoride added to water gets it up to 0.7mg/liter.

    That ends up to be 2 or 3 drops in a 55 gallon drums worth of water. Not much.

    Fluoride is a natural substance and is found in many areas drinking water already. Many areas in much higher concentrations than 0.7mg/liter, so realistically people all over the world have drank fluoridated water for thousands of years.

    You have to well over double the 0.7 before any health issues may appear and the first to appear is at about triple the concentration in kids under 8 years old who drink it for years getting spots on their teeth. The spots are only superficial.

    Going into concentrations even higher than that CAN cause health issues when drank for longer periods of time. All of those cases being from naturally occurring fluoride, which actually effects somewhere north of 20% of the world’s population.

    Which makes the argument that fluoride in our water keeps us passive as being extra stupid, since water sourced around Columbia (the country) is far higher than .07mg/liter and Columbia seems to be caught in violence and turmoil and instability quite a bit over the decades.

    *edit: Colombia

      Its presence in groundwater is how we discovered it’s good for teeth.

      In fact, there used to be so much in some areas,it actually stained the teeth. In Colorado Springs a dentist noticed that the children were developing brown stains on their teeth. In researching it, it was discovered that the “Colorado Brown Stain” was caused by excessive fluoride in the drinking water. But it also lead to the discovery that regions with natural fluoride present but in lower levels than Colorado Springs didn’t have stained teeth, but did have lower levels of tooth decay.

        Yep. In fact, 21% of the world’s natural drinking water used falls within the recommended range for fluoride, while over another 20% is higher and in some countries actually does cause some non-superficial side effects and problems. Those don’t pop up until in concentrations at least 3 times higher than recommended.

    Depending on where you live, there is already enough naturally occurring fluoride in the well water that adding more doesn’t mean much. How else do you think they discovered fluoride helps your teeth?

    Since I live in a rural area and need to have my own well, I know my water contains enough fluoride that it would be silly to add more. But some areas do not have enough naturally present. So it would be interesting to see the water test results for Florida cities to check the amount of naturally occurring fluoride present. YMMV

    fluoridation has nothing to with any teeth-related issues, it was all about the US industry having a way to dispose of fluoride, a byproduct of many industrial activities. You can’t just dump fluoride on a river as it has several adverse side-effects, but it you can convince everyone it is good for their health then it’s okay to dump it on the water supply.

      It does do this. However so does ageing, low sunlight exposure, low altitude, ethnicity, sex, nutrition, neuro-divergence, cell phone use, EM fields… you get the idea.

        Don’t forget the gravitational pull of Betelgeuse. In a very, very small way, that also effects calcification of the pineal gland.

        Does fluoride-enhanced water actually do this, though? Or just pure fluoride? Yes, pure fluoride has an effect, but I always thought the miniscule amount in our water is not enough to actually make a difference to the natural calcification of our pineal gland, anyways.

          From what I have read studies do not show it, however it is believed it does happen because, when the data in those studies is extrapolated for 60+ years, it shows that it should contribute to it, at least

          So, yeah, seems too, but it really isn’t a factor worth worrying about

            Does it though? Did they really do XCT on enough brains in areas with different F in their water to show this over time? And correct for the fact that it calcifies with age anyway? And probably does so variably across individuals and populations (2023 meta-analysis says old white men are the most likely to have calcified pineal glands).

              Well, I have to defer to the conclusions of neuroscientists in the papers I have read, and what my neurologist has told me. You can go and peer review research, if you would like, though.

      Another point that conspiracy bros will bring up is that fluoride is a toxic byproduct of aluminum manufacture and dumping it into the water supply is a cheap way for Alcoa to dispose of it benevolently.

        Honestly it really is sad, we have so many more uses for it

        Every atom of fluoride going into our water is another atom that can’t go into chlorine trifluoride production. Putting it into the water is a huge sacrifice we make for the health of society.

          Real men make chlorine pentafluoride anyway. We have no use for pathetic hypergolic oxidisers with only three fluorine atoms.

          Weird. The only argument I heard, and successfully made it to policy in my area is that it costs tax money and takes away choice. All thus smart stuff is for those damn yankees.

            His joke is that fluoride can be used to make extremely dangerous substances

            From the wiki on the one he mentioned:

            This oxidizing power, surpassing that of oxygen, causes ClF3 to react vigorously with many other materials often thought of as incombustible and refractory. It ignites sand, asbestos, glass, and even ashes of substances that have already burned in oxygen.

        The majority of fluoride that is released into our water supply is a by-product of fertilizer production.
