Im having my wisdom teeth removed-- what should I expect?

I'm 12, and Im having it done tomorrow. I already know most of the basics, but I'm wondering if there is anything the doctors dont tell you. I'm having all 4 removed and 2 teeth uprighted. I'm going to be under general anesthesia-- laughing gas.
thanks!

I've heard about something called "Dry Bone". Ask your doctor about it. It's supposedly rare but it causes extremely bad breath. In the rare chance it happens, it would be shortly after they are removed that it would be noticeable.
