I had all 4 of my wisdom teeth removed in January of 2003, only a few weeks ago actually!
It was a simple procedure, even with 2.5 of them impacted. I was asleep for it and I woke up with no pain, still under local anesthetic for a few hours. The pain after the surgery was nothing compared to the pain I felt before I had them out. If you do have them pulled, I wish you luck and hope you make a good recovery without many complications, like I did.
