You have my sympathy the pain is bloody awful and the sooner you get it down and are out of the pain the better, I had three wisdom teeth out at the same time at Kings about ten years ago and it was done fairly painlessly. Nothing worry about there. It just feels that there's a bit of a hole in your mouth for a little while afterwards until it heals up. You'll be needing to gargle plenty of Listerine afterwards to stop any infection forming.
