I've never had a cavity, which is nice.
Unfortunately, my mouth sucks anyway; I had a gum graft when I was like 6, the drilled a hole to help my molar erupt when I was like 5, then had braces at 17, and finally implants for the upper canines (no adult teeth there). Fortunately, part of missing those two adult teeth was that I'm missing all 4 wisdom teeth.
I wish they just hadn't done anything in my freakin' mouth; then I wouldn't have to worry about keeping everything perfect instead of just cleaning them.
