Tooth Pain Years After Root Canal

Tooth Pain Years After Root Canal

Tooth pain years after root canal

While It’s normal to experience some sensitivity after having a root canal, the pain shouldn’t last for more than a few days. If the procedure was successful, you should feel relieved after a week, and with proper care, the teeth can last a lifetime. Persistent or recurring tooth pain years after a root canal is a likely pointer to an underlying issue. You have the option of going back to your dentist or looking for another competent dental practice to reexamine your teeth and find out what’s wrong.

Can a tooth that had a root canal still hurt?

Sometimes, your root canal may not produce the desired outcome. Below are some of the common reasons why you may still experience tooth pain years after a root canal:

  • Curved or narrow canals were left untreated during the procedure
  • Complicated canal anatomy such as an obstruction in the canal was missed during the original procedure
  • The inside of the tooth became infected with bacteria from the saliva despite the filling
  • The restoration was not placed immediately after the procedure
  • An entirely new problem such as a tooth fracture, loose or cracked crown or filling and new decay

What are the symptoms of a failed root canal?

If you’re experiencing tooth pain years after a root canal, your most probably have a failed root canal. Asides the pain, you should suspect a failed root canal if you notice any of the following:

  • Sensitivity to pressure
  • Swelling
  • Thermal sensitivity
  • Pus-filled or bloody discharge from the canalled tooth
  • Fluctuating symptoms. For example, experiencing intense pain for a week, feeling relieved, and then experiencing the pain again after another month.

Can a failed root canal be fixed?

Yes, a failed root canal can be successfully treated. If you’re experiencing tooth pain years after a root canal, you should get in touch with your endodontist. Many treatment options can relieve your pain and put the problem behind you. However, they’ll need to make a proper diagnosis before deciding on the appropriate approach to solving your problem.

Root canal retreatment

This is usually the first course of action in failed root canal cases. The endodontist will have to disassemble the crown, filling, and other complex restorative materials. Without this, they cannot gain access to the root canals and determine the cause of the problem.

The diagnosis will determine the course of treatment. For example, if there were untreated canals during the original procedure, they would be removed during the retreatment. If there’s a vertical fracture, there is a high chance you’ll lose the tooth.


If retreatment fails or is not indicated for your condition, your dentist may recommend an apicoectomy. During this procedure, your endodontist replaces the tip of the tooth root with a filling. Apicoectomy should put an end to your tooth pain years after a root canal.
