Is it possible to have pain from an old root canal?

Answer by  Sticky (363)

Yes. Occasionally ( like an any anything) a procedure might fail and not achieve the desired effect. Do you have tenderness to percussion? Swelling at the site of the tooth? It is also possible that your body is having a problem in another area and referring the pain so it seems to come from your previously treated tooth.

I do believe there can be pain because of many reasons. The first being maybe the root canal was done wrong. Leaving some decay in the tooth, you might have an abcess where the root canal was done. Also, maybe the crown that covers the root canal might be cracked not protecting that delicate tooth.

It is possible to have pain from an old root canal. If this is the case, the root canal may need to be repeated in order to correct the problem. There may be an abscess ocuring which means eventual bone loss. An endodontist can correct the problem in two visits.

Root canal therapy can fail and the tooth can become infected. Both swelling and pain to either chewing or percussion are some common symptoms.

Perhaps old root canals can be infected but generally speaking if it was done correctly, an old root canal wouldn't affect you badly. Root canals are supposed to get rid of pain, not cause it.
