There is stronger evidence that public water fluoridation reduces tooth decay in children than there is evidence that it does any sort of harm. The only 'harm'

There is stronger evidence that public water fluoridation reduces tooth decay in children than there is evidence that it does any sort of harm. The only 'harm' linked to public water fluoridation is mild dental fluorosis, which is cosmetic. There are natural sources of water that have fluoride levels high enough to cause harm, but these are at levels of fluoride much higher than what is in treated water.
