I had all four wisdom teeth removed in HS during ambulatory surgery. Why I had to go to the hospital, I don't remember, but the worst part was recovering from the general anesthesia they gave me. I barfed blood and stuff while in the recovery room, then went home feeling like a Peterbilt had run me over. Funny thing is, after napping for a couple hours, I woke up feeling just fine, with a slightly sore mouth. No issues after that.
