When did you have the teeth out? Sometimes you do just have to leave things alone for a few days whilst the body heals itself. I hope you recover soon.
I had one wisdom tooth out a few years ago. Not pretty, and one side of my face inflated so much that I looked like a hamster, so clarinet was out of the question for a few days (but on the plus side, it was during the Rugby World Cup, so nothing to do for three days except watch rugby

). It was nevertheless pure bliss to be playing clarinet again afterwards!
