The result “blows the lid off of this idea” that such beliefs are held by only a fringe population of individuals who are uninformed or ideologically driven, says David Bersoff, head of research at the Edelman Trust Institute. “This is not like a small problematic group.”

Yes! Apparently some communities have to remove it from the water first because the naturally occurring levels are too high in modern times now that people brush with it.

I actually have Fluorosis stains on my front teeth. I had no idea what caused that before. I’ve had it for a very long time. It’s just a cosmetic symptom so I’m not worried about it. Something like 25% of the population have staining on teeth from Fluorosis and it’s how the communities can tell when Fluoride levels need to be adjusted in water.

Fluoride levels in water used to be much higher but as society got better at brushing their teeth, it wasn’t needed as much.

I used to have that as well! It does fade with time and in my case, those are the teeth I have with the least wear on them now. (am in my 60's) Still needing a few crowns in the next couple of years, but that's expected after such a long time..
