Never broke any teeth. Took barely any care of them as a kid, but I've only had a few or more cavities every now and then. Far less than I would've expected. Never broken any bones either. I'd like to thank those on the heavy drinking of milk.
I lost all my milk teeth (temporary kid teeth) naturally, in time, and without any problems or need to remove any by a dentist, so that worked out great too.
About a year ago all four wisdom teeth broke in (and stole my stereos) and they caused a bit of a ruckus at first and I thought almost everyone has to remove them. But they're settling just fine and I don't think I need to worry about them either. It's actually been a few years since I last went to a dentist for a check, but my teeth are causing no problems and I only have a cavity or two, I guess.
I am quitting smoking agaaaaain very soon and that will make my gums bleed (more easily) as a side effect, because of the suddenly increased bloodflow in them or something, so looking really forward to that...
