  Why is a link to peer reviewed material getting downvoted ? Not liking the study is one thing but downvoting a link to material without stating a reason is willful ignorance.

    It's absolutely dangerous in large quantities, like most anything else is dangerous in large quantities.

      I am not a scientist and anyone who is should feel free but from what I have read flouride is a bioaccumlator. At what point does it become dangerous to continue to drink water ?

        Drowning is a strong contraindicator. There is also water intoxication, which can be deadly.

          From flouride was assumed... humor noted ;)

        > At what point does it become dangerous to continue to drink water ? According to this page [0], the LD50 of water is 6 liters, so somewhere before that. [0] https://www.compoundchem.com/2014/07/27/lethaldoses/ https://www.compoundchem.com/2014/07/27/lethaldoses/

        > I have read flouride is a bioaccumlator Well, that's something I never heard about, and contradicts even basic high-school chemistry. Where did you read it?

          various places on the net.. some sites are crackpot but others seem ok... I will let you decide which category this falls in https://www.atsdr.cdc.gov/phs/phs.asp?id=210&tid=38 https://www.atsdr.cdc.gov/phs/phs.asp?id=210&tid=38

            There is nothing about bioaccumulation there. Fluoride is one of those ions that diffuse thought and out of our bodies almost like there is no barrier anywhere.

              Animals that eat fluoride-containing plants may accumulate fluoride. However, the fluoride accumulates primarily in the bones or shell rather than in edible meat.

  The reference the author uses to support his claim in this case referred to a review he co-authored that looked at high concentrations of fluoride. Her is one funded by the National Toxicology Program both relevant to community water fluoridation concentration levels of fluoride (low): https://link.springer.com/article/10.1007/s12640-018-9870-x#citeas.html https://link.springer.com/article/10.1007/s12640-018-9870-x#... - which found, for male Long-Evans Hooded Rats at least, " Drinking water exposure at these low levels was not found to alter motor performance or learning and memory in the test paradigms assessed. Low-level F− did not alter thyroid hormone levels and produce neuronal damage or glia reactivity in the hippocampus, or histological damage in the heart, kidney, or liver. The low-level F− diet did not show a significant effect on the behavioral endpoints examined."
