Re: wisdom teeth
They won't put you to sleep even if you wanted it (darnit, I wanted to.) They'll give you a lot of drugs but you'll be awake, and you should forget the whole thing. There's still risks though, more to do with the procedure itself than the drugs involved.
I'd like to know myself about how the teeth are moved around. One of mine was getting very crooked but it doesn't give me trouble so as long as it doesn't move anymore I'm fine. But I suspect as a result of the wisdom tooth pulled, plus a molar next to it, this tooth may be moving around. There's no teeth on either side of it and it's starting to give me trouble biting down, even though I can't actually see it being crooked yet. It was fine until I got the wisdom tooth out. If the wisdom tooth wasn't sideways, it probably would have help move the other teeth into the right spot like it was suposed to.
I'll find out though, have an appointment tommorow.
