People moaning about teeth things, pffftt
I have had 4 child teeth removed (I kept them so well and they didn't want to leave my mouth).
and 4 adult teeth (An attempt to spread teeth out because of misplacement from child teeth not leaving before braces).
Adult teeth hurt quite a bit, and the injection for numbing stuff did hurt a lot, but the most painful thing I have ever had is a Helix Piercing. I've broken bones and stuff before but getting my Helix pierced was something I did not expect to be so painful D:
Oh, also, I know a guy who woke up and it turns out he had suffered from testicular torsion and had to have surgery to spin his testicle back around or something, and when in hospital he turned out to be allergic to Morphine. He did not have a good day.
