I had mine taken out when I was 17... during the first week of my senior year. I stayed awake for the whole procedure which was interesting... everyone says I'm nuts, but I don't see why it was such a big deal. It didn't hurt... but because the teeth were impacted they had to cut into the gums, and then use a drill, and then a chisel/pick-like thing to crack the teeth while they were still impacted. Then they were pulled out.
Like someone on the board said... everyone reacts differently;
I was swollen for about a week. My nickname in high school that week was Simon (the nerdy chipmunk, cause I was in all the honors classes lol). I couldn't eat any solids... had to stick to applesauce, milkshakes, baby food (I highly recommend peach baby food if you like peaches

, mashed potatoes and soups.
However, my best friend, when he got his done... I made a $100 bet with him that he'd swell up... he was asleep for his. Later that night we had plans to go out to dinner with his parents... he looked fine and I'm like "haha I won the bet!" and he pulls out a little baggie with his 4 wisdom teeth. Oh also, we went out to eat at Lonestar Steakhouse... so the solids were no problem for him either.
So yeah... all depends on how you react to it all... best of luck.
