| No, it does not. This is speculation based on a poor
| understanding of the actual science.
|
| Most of our fluoride exposure comes from eating normal food,
| water fluoridation is a small fraction of that. There are no
| measurable cognitive effects in the many developed parts of
| the world with natural fluoride levels far higher than used
| in municipal fluoridation. Furthermore, there is no plausible
| mechanism of action for how this would cause a cognitive
| deficit. Fluoride toxicity is well-understood because it has
| an unusually simple biochemical mechanism. Therefore it isn't
| surprising that the handful of low-quality studies that show
| a weak relationship to IQ loss don't replicate.
|
| As someone who actually worked on fluorine chemistry, it is
| disappointing to see how credulous even many people with a
| STEM background are on this topic. The absence of a plausible
| mechanism of action alone should raise serious questions.
