Lost count of how many times the dentist has shoved needles in my gums and drilled teeth.
Two root canals.
Last root canal was done by some quack who shoved the wrong size metal rods into my tooth so hard that the damn tooth cracked. Holy shit was that painful! Still haven't got that one fixed yet.... they are gonna have to pull it, do an implant into the jaw, and then put on a fake tooth....
I remember when I was getting braces I had a loose tooth they had to remove to avoid bad shit happening or something. Got the tooth pulled the next day and it hurt like hell, and looked like it had plenty of root still on it. So i'm sitting at home with some gauze in my mouth bleeding profusely when I feel something in my mouth wiggle. They had pulled the wrong tooth. It was at about that point I flew into a pissed off rage. Turns out they had accidently pulled out a perfectly fine, perfectly solid tooth with all its root still intact. It's amasing how loud you can yell with a mouth full of gauze.
