go for the nitrous

nah, most of the time i don't even need anaesthetic. i'm more worried about inhaling the toxins.

wow. I usually need everything in the arsenal

wow. Nothing? I usually need a couple of shots of Novocain. The first one still leaves a strong twinge when they drill.

good luck though! Teeth are useful things to keep around!

i'm 51 and still have my teeth in great condition (except for a bit of grinding in my sleep)
