Curious -- I've never thought of this as the sort of thing he would deal with. I associate him mainly with back pain; while I know he does other things as well, the jaw isn't one that would have occurred to me.

For the moment, I'm not too worried: like I said, the pain is quite modest and occasional. (Really, the worst of it was the concern that Something Was Wrong, and I didn't have any clue what.) But it's a good option to keep in mind, should things get any worse -- thanks!
