When I had mine out I requested that I was put to sleep, they tried to discourage me but I just couldnt have gone through with it awake....One of my wisdoms was only slightly exposed, and when I went down to the theatre, the man looked at my x rays and said easy peesy! Much to my relief...It was all over with quite quickly, but seriously though if you feel that bad about it, I would go and have a chat with the dentist about other options you can have, ie, being knocked out, if your that afraid, tell them what you want and stick to your guns, at the end of the day, they are working for you!
