Without comment on the question of health benefits or harms, I'm curious whether you've had the well water you use tested. Fluoride concentrations in bore-well water varies quite widely, and concentrations higher than fluoridated tap water not uncommon. There are several areas here (in Aus) where fluoride is removed to reach the recommended concentration of 0.5-1.1 ppm. This obviously varies based on location.
