I brush my teeth well but I never remember to floss oops. I've had two cavities, I believe. :T But they were minor and didn't even require numbing to be filled.
I do have braces [I'm younger than the majority of PC members] and they'll come off in two years, meaning I'll have had them for a total of four years. D:
I have a really minor overbite but had to use two different jaw appliances (at different times) to fix it because it was really bad before. I also have TMJ but it doesn't give me much trouble. Just crackles and pops a bit when I open my mouth the whole way. It hasn't gotten totally stuck yet. n_n"
