I got a root canal on my back upper molar because of a dead nerve. It took 3 mths to complete, a lot of it was insurance problems, but either way I spent $1000 out of pocket. It still hurts, and now the dentist is saying that if it continues to hurt either do antibiotics or extract the tooth. I'm wondering if I should just extract it. I may have to do another root canal on my bottom molar. I have an abscess on that tooth; I got a root canal done on it at least 8 years ago. I don't want to spend any money. That tooth doesn't hurt all the time, only sometimes, but I know if I have an abscess I should get it fixed asap. Should I just extract both molars and save money? That is what I'm leaning towards.
