Well I had the root canal 2 days ago. How long can your tooth be sore from a root canal? My tooth is still sore and achy. All the sensitivity is gone, but the tooth still hurts. It hurts on the back of the tooth were they drilled and were the temp. filling is. But that is were my tooth was hurting in the first place, so I was wondering what is normal after a root canal.

They thought the root was dying in that tooth because of sensitivity to cold and hot (especially hot) and the tooth aching for no reason they could find. Plus I was accidentally hit in the nose 6 months ago which also made them think the nerve in the front tooth was dying. But there was no infection or anything like that in the tooth.

Thanks!
