The dangers of fluoride (tap water fluoridation)?

Dr. Greger, I have heard some talk about the dangers of fluoride. When I research this all I stumble upon are propagandists websites without scientific backing. Is there any truth to these claims that fluoride in our water supply and toothpaste is damaging our health?

Answer:

The proposed EPA changes to water fluoridation have sparked a resurgence of many of the old anti-fluoridation arguments, which as far as I can tell were successfully debunked over 50 years ago. According to the CDC, fluoridation of drinking water joins vaccination (another unjustly vilified practice) as one of the greatest public health achievements in the last last century.

    Why do they think that something that has been show to help topically, will cause the same benefit when ingested? It doesn’t make any sense to me!

    • Carol

      I agree. I drink distilled water (for 14 years) and get my minerals and vitamins from a great vegan diet, supplementing B12 and D. Wht try to be healthy and eat organic clean food, etc., and then 6-8 glasses a day of dirty tap water containing chlorine, floride, arsenic, etc., etc. Those that say tap water is tested and has to meet special requirements… humbug! Just as our meat and fish and chicken and on and on is so carefully inspected. Don’t believe it!

      • Borka223

        If you are used to the taste of distilled, what does tap water taste like to you?

        • kevin

          it tastes like ass

    • kevin

      because they are aiming to calcify your pineal gland

  • Marta

    Dr Doctor, I have just read at a website of a company producing cosmetics for vegetarians, that human body absorbs fluoride only until late teens, therefore we should not take it any later. Is this true? I cannot find any research results supporting this. Regards, Marta, PL

    Dr. Greger,
    I recently read that the fluoride added to 90% of drinking water is hydrofluoric acid which is a compound of fluorine that is a chemical byproduct of aluminum, steel, cement, phosphate, and nuclear weapons manufacturing. Is this true? If so, common sense dictates that floride might not be worth the benefits…

    • Toxins

      HF, called Hydrogen Flouride is an extremely lethal and acidic compound that will burn through all organic matter and most inorganic matter. I highly doubt that the drinking water contains HF as a sip would burn a hole through the esophagus.

      • marklloyd

        Ann didn’t post that water was 90% HFA, but rather, that 90% of the water supplies have HFA added, a -very- small %. No “hole though the esophagus”, but still an unnecessarily-added poisonous by-product of aluminum smelting. How is it that the US National Research Council has taken fluoride off the list of essential nutrients yet still considers it “beneficial” ? Something stinks here.

  • emerson berlanda

    this page does not put any information about fluoride, no pro no cont,
    I’m sorry but what’s the use of creating this page?where is the explanation about fuoride be bad or neutral for our health?, I only saw a comment from carol, not any information on the main page, only in the comments?
    I wanted to know the real scientific facts about fluoride in tap water

    • Thea

      emerson berlanda: If you look above, you will see Dr. Greger’s answer to this question. In his answer, he has a link with text “debunked”. If you click this link, you will be able to download an 85 page paper on the topic that should provide the information you thought was missing. Hope that helps.

      • Susan Groggins McNamee

        The study was written in 1960

        • Thea

          Yes. I believe that was Dr. Greger’s point: ie, that this issue has been worked out for decades. Perhaps there’s new information since then? I don’t know. I didn’t have time to read the paper to find out if the conclusions would likely be timeless. I was just responding to the confusion about there being no scientific answer to the question. The answer is there, whether you like it or not. :-)

        Rick, Mercola is a quack.

        • Derrek

          Why is he a quack? Is distilled water safe to drink?

          • Toxins

            He advocates for many things that are part of the fad diet sector. He sells tubs of coconut oil and advocates for raw milk amongst other things. He also claims without evidence that we should not shower with soap because we cant absorb vitamin D when we do. He is not the most reliable source, and is geared towards having his consumers buy his products.

            As for distilled water, I can’t imagine why it would be harmful. Bottled and filtered tap water has some trace minerals in it that are negligible, but other then that, its as H20 as bottled water is H20

          • Derrek

            What kind of water does dr. Greger recommend? There are claims that distilled water takes minerals from body.

          • Toxins

            Dr. Greger does not recommend a specific water, it is not an issue. And I have seen the claim you have made (specifically from Dr. Mercola). You have to read his article with a skeptical eye, he provides zero citations to back up his claim.
            http://www.mercola.com/article/water/distilled_water.htm
            Much of the food we eat is full of electrolytes, the majority does not come from water. There are trace minerals found in water that are negligible (Na, K, Mg, Ca) but you can find these in much greater quantities in food. He is simply trying to scare his audience needlessly.

          • DanielFaster

            Whatever water or other beverage you drink however, it should NOT come out of a plastic bottle or can which may leach bpa, phthalates or other endocrine disruptors or carcinogens into the contents. Distilled or RO water will absorb more from the plastic since it is more corrosive. Bpa-free often just means they have added other untested chemicals that could be worse than bpa. Also just because they tested a brand of bottle or can for endocrine activity does not mean the next one of the same brand wont – because the source can be changed or the supplier may change thrir formulation.

  • ted

    I find that there are many misconceptions about fluoride. Fluoride is
    not necessarily toxic. It depends on the concentration. The drinking water in
    Denver, CO, for example, contains naturally-occurring fluoride very close to
    the levels that are currently recommended for drinking water fluoridation (0.7
    mg/L to 0.9 mg/L). The water company (Denver Water) actually removes some
    fluoride when the naturally-occurring levels exceed the recommended levels. Much
    of this water comes from the Platte River which is used by many other cities on
    down the line. This water supply has been used by millions of people over 100′s
    of years without problems related to fluoride.

    I find that the public’s perspective is that the government adds all of this
    fluoride to all of the drinking water. That’s simply not true. The communities
    that add it are using a target value that’s very close to a natural
    concentration of fluoride, just not the natural concentration in their
    particular water supply.

    • Thea

      ted: Thanks. That’s very helpful.

    • Jake

      ted it depends on the way the fluoride is complexed. In naturally occuring waters its a different complexed fluoride./ The fluoride they lace our water supplies with is from industrial waste of aluminium production. You need know the history of this scam. There are docos about it., 1000s of patriots spent half their lives trying to get the word out to everyone else.

      • john galt

        Our city buys industrial flouride from Red China (FOIA your water plant; the workers hate the stuff it is so toxic.

  • Susan Groggins McNamee

    Many European countries have ceased fluoridation. One wonders why?

    • rick

      Fluoride is in the halogen family along with iodine. Fluoride has been shown to inhibit the ability of the thyroid gland to concentrate iodine. Research has shown that fluoride is much more toxic to the body when there is iodine deficiency present. There have been no studies which prove that long-term ingested fluoride has any positive effect.
      Many medications that contain fluoride have been pulled from the market due to serious adverse effects. A study in New Zealand found that there was no difference in tooth decay rates between the fluoridated and the non-fluoridated areas. Many European countries have recognized the fallacy of adding fluoride to the water supply and have stopped the practice.

  • Rita

    Dr. Greger I recently read a paper by Dr. Gerard Judd about fluoridation written in 1997, the footnotes themselves are interesting. http://www.cosmicchannelings.com/cos/non-cac/Good-Teeth-Birth-To-Death-How-To-Remineralize-Teeth-Dr-Gerard-Judd-Img-OCR-nc001.pdf For now I think I’m skipping fluoride. Thank you for all the valuable information you provide.

  • JP

    Dr. Greger,

    is it safe to regularly drink distilled water?

    Many different answers

    For example:

    Yes: http://chemistry.about.com/od/waterchemistry/f/Can-You-Drink-Distilled-Water.htm

    No: http://www.mercola.com/article/water/distilled_water.htm

  • marklloyd

    The late Dr John Yiamouyiannis’s book: “Fluoride, The Aging Factor”, convinced me that fluoride is, at best, unnecessarily added to municipal water supplies & not responsible for improved dental health. At worst, it’s a poisonous waste product of aluminum smelting. Have you read the book?

  • Derrek

    What about dr. Paul Connery the case against fluoride?

    Hi Mr Jew Greger, a recent Harvard study found that populations who had water-fluoridation around the world had absolutely no correlated improvement in tooth-cavities rates and that in fact they found an astonishing correlation with 15% lowered IQ in teenagers tested in those populations.
    I think your jew masters at the Mossad are going to have to get you a new ID mate. Your mask has fallen off your face.

    • Jake

      And PS I could have got a doctorate in any of the BSc (chemistry), BE (Chemical) or the MBS (Business SYstems) but I had no interest in studying in any of the universities all occupied by nepotistic clan of evil jews.
      I know your game you pervert.

  • Annette

    Sorry but as soon as you said “According to the CDC…” you lost me.

  • Alan

    Dr Gregor, i appreciate the info that you put out, BUT you can keep your fluoride and the vaccinations.

  • god

    Michael Greger M.D. has just proven himself to be a completely incompetent moron……DRINKING RAT POISON IS NOT GOOD FOR YOU!

  • ash6222
  • Bob

    LOL at confident doctors like this who are so breezy with their “debunkings”… science is an ongoing, evolving process, as the recent Harvard fluoride study demonstrates.

  • Ian

    I think adding any form of fluoride to the water supply and then forcing people to pay for it through water rates, as we do here in the UK, whether the amount be deemed beneficial, harmful or otherwise, is simply dictatorial. I make the choice to apply my fluoride topically via toothpaste, but when it comes to drinking, I desire a liquid as untainted by artificially applied chemicals and heavy metals as is possible to supply safely. It doesn’t matter what the arguments for and against medicating supplies are, but when I know my wife reacts allergically to fluoride toothpaste, we wonder how she, and others, are reacting inside to Birmingham water. I don’t think it’s unreasonable to be concerned by this regardless of the alleged historical safety assurances.

  • nasr

    There is scientific backing, look at the many countries that do not add fluoride and compare to those that do. Tooth decay has declined at the same rate… Forced medication as a form of repression may be the real danger.

  • laconic

    I discovered after years of getting sick every time I required antibiotics in a country where flouride is required by law for tap water that all I had to do was find water without flouridation and all of the antibiotic side effects disappeared.

  • rick

    I think this link will convince everyone that their is no benefit to fluoridation of water.

  • Derrek

    What’s dr gregers view on intermittent fasting and fasting?

  • Derrek

    What are your thoughts on fluoride? I’ve read a lot that fluoride is toxic and should not be consumed. This is a site with a lot of interesting information:
    http://fluoridealert.org/issues/health/. Doesn’t fluoride have a lot of negative health effects, such as what is added to the water supply.

  • Lawrence

    Most european countries reject the use of Fluoride in the water supply. http://www.actionpa.org/fluoride/countries.pdf I tend to agree with them.
