My daughter will be 13 soon. We have mostly lived only in places with well water, with the exception of an 18 month or so stay in an area of Richmond VA with city water.

She does not have any fillings, she gets a dental exam once every couple years. By the time I was 13 I had about 6 amalgam fillings, I grew up drinking flouridated water but I also had a lousy dentist who may have needed extra money for his early retirement and funeral.

We stopped using flouride toothpast a few years ago. My teeth are also much whiter and no cavities in many years. i fight mostly only a battle against the damage done to my teeth by dentists as a kid.

Personally I think the world would be a better place without dentists.
