Not my tooth.

Dr. Bishop pére took x-rays of my upper gums and didn't see anything. He poked around my tooth and had me bite down, and it didn't hurt. He did notice that the metal filling isn't in the best shape in the world, so if Tuesday's CT doesn't show anything wrong with my sinuses, I should call them back and they'll take the old filling out and look around to see if there are any cracks or the root is damaged, and if not, they'll put a resin filling in. He'd rather avoid doing a root canal if it isn't necessary, and he thinks sinuses is more likely.

The red, painful spot on my gum is a torus, or a bone spur on the gums. I have them on the lower jaw, so it makes sense. Apparently they're related to grinding your teeth, according to one dentistry website that turned up on the internets.

(Oh, yeah, this morning I got a call from the ENT's office with my CT appointment, Tuesday morning. I guess they showed enough evidence to BCBS to get them to authorize it.)
