Why do I need a root canal on a crowned tooth?

Did you receive a crown on one of your teeth, and now someone told you that you need a root canal on that same tooth? But wait, you say, I thought the crown was supposed to fix my problems? It is true that in some situations it is necessary to get a root canal through a crowned tooth. We’re going to discuss the causes of that here, but if you have more questions or want to talk to a specialist, we can help. Call our Lane and Associates Family Dentistry team at 1-877-LANE-DDS and speak to one of our team members for information and guidance, or to set an appointment to see one of our dentists.


So, why do I need a root canal on a crowned tooth?

The problem with teeth is that they were not designed to deal with a lot of the stress we put on them or the things we ask them to chew on. Root canals are necessary when the pulp inside your tooth becomes infected. This can be caused by decay, a chip or crack in the tooth, or an old or poorly placed crown. If infection of the pulp is left untreated it can cause inflammation and serious pain. During a root canal, the infected pulp is removed from the tooth and the inside of the tooth is cleaned and disinfected. It is then filled and sealed with a material called gutta-percha. After the procedure, the top of the tooth is restored either with a new crown or filling, or by repairing your existing one.


Sometimes, it can become necessary to perform a root canal on a tooth that already had a crown put in. Crowns are typically installed to repair teeth that are cracked or damaged and in need of repair. They are different from fillings, because fillings are usually used to repair very small areas of damage. Crowns are used if the damaged area is larger and needs a different solution. Sometimes the pulp inside a tooth that had a crown installed will eventually become infected and a root canal will become necessary. This could be any length of time after the crown is installed, 5, 10, 20 years later. When initially examining the tooth before installing a crown, your dentist should check to see if the problem would be better addressed by a root canal. If you need a root canal immediately after you receive a crown, it could be simply that not all teeth are created equally, and unfortunately your tooth became infected after receiving a crown.
