Awfulsome!

A longish time ago, when I was very small, I ruined the #19 tooth in the back of my mouth by not brushing it or something (I don't remember, I was very small).

I had to have a root canal, which is pretty awful in itself, but the story doesn't end there. Turns out, this tooth keeps getting infected. Don't know why, but when I'm stressed it gets worse, and when I'm happy, it subsides. Lately, I've been pretty busy. As a result, this:
That great big dark spot you see there was +infection -bone. The bacteria actually ate up the bone. Those were some hardcore bacteria. Oh well.

Everything is ok now, and I'm getting it fixed and re-filled and everything, but for a while there I was carrying around bone-eating bacteria in a hole in my jaw. I still can't decide whether that's awful or awesome.
