That's probably due to the fact that I had 4 molars taken out when I got my braces - so there's enough room for the wisdom teeth to pop out.
Anyway, I opted for the novacaine over getting gassed/knocked out.
While we waited for the numbing to happen, the assistant slowly laid out these tools:

Dr. Lee only used the second and third tool: the squiggly icepick looking one and the plyer.
The squiggly icepick was used to wedge into the gum, to loosen the tooth - kind of like a crowbar. I could hear cracking while he did it all around the tooth. When the tooth was loose, he used the plyer to take it out.
Too bad, no fun drugs. I only got scripts for Tylenol #3 (with codine) and mouthwash.
