Fluoride is weird. Everyone just assumes some is good so more must be better, and any research into dental fluorosis (over exposure) is shunned. I believe primarily because prior to dumping it into the water and every dental product imaginable fluoride was expensive to dispose of and we produce a ton of it as a byproduct of making fertilizer.
