I have two chipped teeth and and some sort of gum problem. I knew about the latter since I was a kid and was supposed to use a specialized mouthwash to help it, but of course I didn't give a crap back then. So now my gums are in worse condition than before. Ech.
I don't know for sure how I got my chipped teeth, I just found them like that a few years ago, but my dad believes it might partially be from my wisdom teeth pushing the rest of my teeth together. Not sure when I can get that taken care of. Money and stuff.
