Ok, we are mixing up our experiences here folks. The OP is going in for ORAL SURGERY to cut out their wisdom teeth. this takes hours, general anesthetic, and often is done at a hospital, not a dentist's office.
VERY VERY different from my experience of having my wisdom teeth in already...where it was a shot of novacain and 30 mins later 3 of my teeth were removed like everyday business.
they were healthy, straight, not impacted...just simply didn't want them. hell i didn't even get anything stronger than 600mg ibuprofen for the pain (and there was no after pain either).
hell the next day, I ate steak, and crunchy garlic bread!
The OP, however, is going in for minor surgery. drink some whey shakes, and get yoru rest so you recover quickly.
AND DO NOT DRINK OUT OF ANY STRAWS FOR 2 WEEKS. if you do, you'll suck out the blood clots in your teeth holes and get dry sockets. which are painful and can get infected easily.
