Terry, part of cavities is heredity. Although not brushing doesn't do a whole lotta good. Sonic had eight cavities...he doesn't brush. HOWEVER...interesting story here.
When S. was in the orphanage in Hong Kong they brushed very on-and-off and the kids were not made to do a good job. So when we adopted S. I took him AND my bio. son, who was made to brush twice a day, to the dentist, expecting the worst, thinking about how many cavities S. probably had from sweet eating and not brushing. It actually gave me a nervous stomach to think of the cost. Guess what?
S. had no cavities. None. He has never had a cavity in his life, in fact, and he is thirty six. My ex told me this as S. doesn't speak to me anymore. But no cavities is amazing, especially with his horrible start. So did I get off the hook, money-wise? I did not. My son 36, who was maybe six at the time had, ten cavities. Count 'em. TEN! Now I remember my mother telling me, in a rather nasty way, that I cost her a bundle because the first time I went to the dentist I had TWENTY-FOUR cavities. Yep. Twenty four. My entire DNA clan has tons of cavities and gum issues.
Jeez, Terry. I never expected that...lol.
Hey, not saying your kid wouldn't have had better dental results if he'd brushed, but there IS a hereditary factor involved.
I'm sorry that your son has to have filling in all four of his front teeth...ugh!
