I feel your pain. I had a root canal many years ago.

Also, my coworker went through this a couple months ago. Started out with a root canal and ended up having a major infection. She was off work for almost 2 weeks!

I had a root canal done about 20 years ago. It was in the back right, next to last tooth. I had a crown put in. The crown fell out twice. Then I had what they call an Apicoectomy which involves actually removing part of the root. So, now I have one root and a half. I had a new crown made and that one kept falling out. Finally I just left it out. I have been planning on just having the remaining little bit of tooth removed since it is way in the back but haven't done it yet. The doc wanted to do a bridge to the tune of $2,000.00. I passed on that.

Hope you get this straightened out and feel better soon. There is nothing worse than mouth pain!
