I grew up in the US on unfiltered well-water. Not sure what the fluoride content was because the water was never tested. However, I always had dental problems as a child. However, when I left my childhood home to attend university (and moved into the city afterwards), I haven't had a problem since. Then again, this is just one anecdote.

My mother grew up on well water and has never had a cavity in her life. My dad grew up mostly on city water before fluoridation. He has had terrible problems with his teeth.
