When I was young, my parents took me to the dentist every 6 months. I had a bunch of cavities. My children (ages 15, 12 and 10) have been to the dentist ONCE! Only the oldest had A cavity. I got it filled (not knowing any better) and thankfully, it was a baby tooth, so it has since fallen out :) Is there a coincidence there between them never going and never getting cavities? Probably. I am in the process of getting them to OP, but so far no luck.
