I had all 4 of mine out about a year back under general anaesth. The operation itself wasn't bad (obviously because I was knocked out) but the two weeks following it were horrible. I couldn't eat because I was in so much pain and I had to stick to foods like custard and ice-cream which is bad because I don't like too much sweet stuff. All I can say is make sure you follow your doctor's instructions carefully because I didn't and I ended up with a dry socket which is by far the worst pain I have ever experienced in my life - hence the extra time it took for me to recover.
