Can a Root Canal Fail?

Posted on: January 1, 2020

root canal Houston, TX

Needing to get a root canal but heard that they can fail? Yes, it is true that root canal therapy can fail. While this may be a little disheartening for you to hear, understand that the failure rate of root canals is very low. If you currently have a tooth that is in need of treatment, then it could be lost forever. So the more you learn about the root canal process, the more confident you should feel about having the procedure performed.

It is always ideal to save a tooth rather than lose it. This is because good oral health depends on having a full set of teeth.

Information about failed root canals

Signs that a root canal has failed

When a successful root canal is performed, it will take a dental patient about three to four days to recover. The area will remain sensitive over the next seven to ten days or so. When a root canal fails, instead of the area improving over the next few days after treatment has been performed, it will remain painful or even get worse.

Common signs that a root canal has failed:

  • Swelling that will not subside after a couple of days
  • A tenderness that will not go away after three to four days
  • Experiencing pain when biting down or chewing soft foods
  • Seeing a small white bump or a blister near the area
  • The tooth feels loose or looser

Why would root canal therapy fail?

Root canals fail when all of the bacteria is not removed during the actual root canal or reenters the tooth after the root canal has been performed.

Common reasons for root canal failure:

  • The removal of all bacteria inside the damaged tooth was not properly removed
  • The dental filling fell out, which means the tooth is no longer protected
  • The dental crown was not fitted correctly
  • The tooth is now cracked or has further cracked, which means it is no longer protected
  • In time, a root canal can fail when the patient does not provide themselves with the proper oral care, which creates more dental decay

Retreatment options

When a root canal fails, there are retreatment options available. In order for a dentist to determine which treatment a dental patient will need, they will need to fully evaluate the situation.

The most common retreatment option includes redoing the root canal. Another option includes performing a more in-depth root canal procedure, which involves a dentist performing a minimally invasive surgical procedure that can give them access to the root canal through the gums. The last option is to extract the tooth from the mouth and is considered to be the last resort.
