I had all 4 of mine out at the same time a few years ago. Here are some tips:

Like people above have said, the frozen peas used as an icepack are very useful.

I didn't have any problems with milk products after the fact. Milkshakes from Wendys are great, just use a spoon.

MOST IMPORTANT THING-----DO NOT DO ANYTHING THAT WOULD CAUSE SUCTION IN YOUR MOUTH.... This should be in the doctor's instructions to you. I am specifically talking about drinking through drinking straws or smoking cigarettes. If you use a spoon like for soup or something, don't slurp/suck out of the spoon, just use the spoon to pour it in your mouth.

If you do create suction, you could dislodge a part of the skin in the incision area that is very important and you could get what is known as "dry sockets". Not pleasant situation, those buggers hurt a lot. Just make sure you skip the suction thing for about a week and you'll be fine.

And really, don't worry about it, like everybody said, the anticipation before the surgery is the worst part!

Good luck!!!
