So I'm home from the endodontist. The saga continues... after examining my tooth he determined that it is not a good candidate for a root canal - the other dentist was wrong. He said he could do it, but it would be 100% sure to fail, he said there is basically no hope to save this tooth and recommended pulling it. Of course, they couldn't do that today.... so I scheduled to have it done 2 weeks from now. That's okay. It's not hurting right now, and we have some leftover oxycodone from when h had a tooth pulled a few months back in case it gets bad again before.
