I had an experience exactly like yours about 15 years ago. Except that I was literally screaming in pain...yes, screaming. The office had closed, and I was in there alone with this hideous freak; I tried to tell him that the Novocaine wasn't working...but he wouldn't listen. I was traumatized for years. I could not quit sobbing for at least 8 hours after the "procedure."
A few years later, when I had worked up the courage to go back to a (different) dentist, I discovered the full extent of the horror. He looked at my mouth, then X-rays...and asked me if I realized that a very large chunk of jawbone had been broken off along with the tooth in question...he couldn't believe it.
I have lived for 15 years (since my mid-twenties) with a giant "gap" where tooth number "4" should be; and a gap in my jaw that extends well above it
I am more than willing to pay to have it replaced, but because of the complete lack of remaining bone, a bridge is not an option....there would be a giant hole above it. I have seen two reconstructive dental experts, both believe that so much bone is gone, that attempting to rebuild the area would be risky. Anyone with knowledge of new procedures...let me know!
BTW, I later read that the ghoul had his license taken away.
Man, I feel for you. By the way, did you ever read the Jim Herriot story about the dentist that knocked his tooth out with a hammer and chisel? The nurse pulled him aside before the extraction and told him the dentist was crazy, and had no idea how to pull teeth...
