Will my tooth decay under the crown which had the root canal? What causes pain in tooth that had root canal years ago? Why am I having pain in a recently root canal treated tooth? What is the recovery time after a root canal?
It’s rare, but a tiny bubble of air can also be forced out of the root tip , causing pressure and pain.
When a tooth becomes sick due to decay or infection, the ligaments surrounding the tooth may experience some swelling and inflammation. This is the cause of your tooth pain. It takes some time after a root canal procedure is done for the tissues to return to normal and for the pain to go away.
If the cause of the pain is due to a missed canal , the endodontist will need to open the tooth , remove the filling and try to find the canal. It’s still possible to bite down and crack the root or an existing crack under the crown may grow down the root. If the tooth has a vertical fracture , the dentist would. This may cause pain when biting down on the crown in certain ways.
Sometimes the pain will come and go.
