We moved to Montana when my child was a teen, and the dentist immediately remarked that my child must have grown up somewhere else because of her teeth being in such good condition.

Most local teens grew up on well water and their teeth suffered for it.

There are lots of people with excellent teeth in different parts of the world - and most of them are not using flouridated water. I think the diet does make a difference in dental health
