I kept all my wisdom teeth....then about 10 years ago I started getting pains in a back tooth....put up with it, but finally it just started to get worse. But, you know how pain is in your mouth, very hard to pinpoint which tooth. the dentist tapped on the tooth I thought it was, but I felt OK...then he tapped on the wisdom tooth...I yelled. he said that's it! and tapped it again...I yelled again. He told me that whatever the problem was, I needed to get the tooth out...so he sent me to the oral surgeon. The surgeon's x-ray showed that the wisdom tooth was cracked. So....he shot me full of novocaine, and had me go to the waiting room. Called me back 10 minutes later...I said it still hurt just as much, so he gave me another shot. 10 minutes later, he called me back...I said I still felt it just as much. He pulled it then anyway while I screamed and pounded on the chair....felt fine as soon as the tooth came out....the moral of the whole story? Don't see an oral surgeon near closing time.........Take care, Eric
