This may not be asked in the right place, but this is the most reliable one I could think of. I went to the dentist today with my father for a 6 mo. checkup. We both (unless his habits changed while I'm at school): *Brush our teeth twice daily *Drink soda *Drink virtually no milk or water However: *I drink 1-2 sodas/day, and he drinks 2-4. *He smokes cigars, I don't. *I drink copious quantities of Kool-Aid, but that's only been for the last 2 weeks. *He uses Listerine when he brushes. *He rinses his mouth (with water) after he eats. The dentist (I think it was actually a hygienist) said that my teeth are about to all rot out and my gums are about to just die, but that his are fine. Does this sound like quackery to anyone else?
