Getting your cavity filled doesn't really hurt at all. There still is some drilling involved, but your so full of nova cane that you won't even feel anything.

I've never had my wisdom teeth pulled but my g/f did. They put her to sleep so she didn't feel anything at first. But later after she woke up and the drugs wore off, she said it hurt like a bitch. She also looked like a chipmunk for about a week.

Edit: People posted and now my post seems redundant.
