That got me thinking - I wouldn't make the same mistake, but I'm curious - is the jaw just the moveable part that holds the bottom teeth, or does it also include the part that holds the top teeth? I know the upper teeth are part of the skull, but is the jaw the joint thing - like the elbow or knee, or what?

Oh and one more thing I've always wanted to ask a dentist - what the hell is up with wisdom teeth?
