I went to the dentist again today so he could finish the root canal. He didn't finish it last week due to the infection. Well, it's still infected, so I have more antibiotics :( He did finish the procedure though, so that's a plus. My tooth is a little more tender than it was last week, but it doesn't hurt, so that's good. He did refer to my tooth as interesting though, mostly because he thinks I injured it when I was 8-12, as opposed to 18, based on the size of the root, and the x-rays. I definitely did injure it when I was 18, but maybe I did before that too?
The only bad news. If the infection persists, he'll have to go in with a scalpel through the gum to clean it out. That will probably hurt. Here's hoping it cleans up.
