Medicine’s Response to the Changing Science on Fluoride Safety

Ironically, the anti-fluoridationists had historically been accused of their "anti-scientific attitudes," but now it’s many of the pro-fluoridationists. How did the medical and dental community react to U.S. regulators’ total 180 over water fluoridation, going from presumptively safe to presumptively dangerous?

We can get the best of both worlds with topical application of fluoride, so I continue to advocate for the use of fluoride toothpaste, but pregnant and breastfeeding women may want to consider non-fluoridated water sources to reduce the apparent risk to the developing brain.

This is the final video in my series on water fluoridation. If you missed any of the others, see:
• Why Is There Fluoride in Water? Is It Effective? ( )
• Side Effects of Water Fluoridation: Dental Fluorosis ( )
• Is Water Fluoridation Safe? ( )
• Why I Changed My Mind on Water Fluoridation ( )

You can also watch the recording of the webinar that I did on this topic, which includes a Q&A at the end:

I mentioned the example of lead exposure. If you want to know more, I have an entire series on that topic, starting with How the Lead Paint Industry Got Away with It ( ).

I have a lot more videos on dental health ( ), including a series on oil pulling ( ) and tongue scraping ( ).

    Do water filters remove flouride from water?

    • @anderslvolljohansen1556 says:

      Some types do, like some that use ion exchange resin.

      Reverse osmosis removes dissolved salts in general including iodine, but they produce a reject water stream with an elevated salt concentration.

    • @anderslvolljohansen1556 says:

      If you spit it out then that’s probably safe for you.

      It’s the developing brain of the fetus that is sensitive to tiny amounts of mercury, lead and, as recently discovered, fluorine.

      That means those who are pregant or could become pregant in the near future should be extra careful.

      Tea may be another source of fluorine, but that can vary.

    I had a very close friend for decades who warned me about fluoride back in the 1990s. It did influence me for awhile, but eventually the idea lost credibility, as it seemed all of the anti-fluoride proponents tried to convince laypeople instead of the scientific community. They also frequently peddled conspiracy theories, about fluoride as well as most everything else. It is hard to pluck out from so many conspiracies the one that contains actual risk to humans.

    The layperson is poorly equipped in time and training to read and understand scientific papers. Even the broadly trained generalist must rely on experts to dissect the data and review the findings.
    It would have been nice to have these studies done earlier and reexamined our water quality, but even though there were people raising concern about fluoride as a substance, they were also claiming it an intentional conspiracy, wide in its scope, but run by a cabal of globalists.

    Why would anyone take that seriously?
    These same people warned us about “chemtrails” and faking the moon landing.
    I’m glad to know that public health is trying to catch up, but I am living in a country that still has extensive lead piping in many municipalities. Along with PFAS and other dangers.
    But I’m not looking forward to the wackos never shutting about about being somewhat right this one time.

    • @dave007dog says:

      Conspiracy theorists really can poison the well when getting good science info out. They can make a topic so taboo that researchers don’t even want to study things like water fluoride. They still would have to answer for all the things that they said it was for, like mind control or whatever.

    • @SamuelNoaGreen says:

      They were not really right with their conspiracy theories. Because they had outlandish and unsubstantiated claims. It does seem that it is bad for some people in the long run and it should be removed.

    What’s the effect on microbes from fluoride?

    How does guzzling loads of fluoridated water affect our microbiomes?

  • @derbybOyzZ says:

    This same view of the medical establishment and people at large is the same as the attitude towards EMFs. The default response is to say “It isn’t ionizing!” and to brush it off. A more nuanced response is to worry about other effects it has on the body, such as calcium channels in cells.
    The EMF debate is a bell curve, it has people on the left that think “EMF SCARY”, the middle has “it’s not ionizing so it’s safe”, and the right of the bell curve has people that are interested in mechanisms that could potentially underpin the effect EMF has on the body.
