Infected Root Canal Warning Signs



When you are concerned that you may have an infection after having a root canal performed, then knowing the warning signs is essential to your good overall health. Root canals are often a necessary procedure in order to save a tooth at risk of being lost. Even though root canal complications tend to be few and far between, they do exist. This makes it essential for you to pay close attention to any warning signs that may be present.

Why would someone need a root canal?

The reason someone would need a root canal performed on one or more of their teeth is because the soft tissue inside the tooth is either inflamed or infected. Some of the more common reasons someone’s tooth is inflamed or infected include a serious amount of decay on the tooth, a severe crack or severe chip in the tooth, a dental crown that is not working properly and having many procedures performed on one particular tooth. While some people would prefer to have their tooth pulled vs. getting a root canal performed, it is always recommended to keep one’s natural teeth for as long as absolutely possible.

Infected root canal warning signs

The following is a list of common warning signs of infection after someone has had a root canal performed on one or more of their teeth.

  • Ongoing pain that does not stop and gets worse when they bite down
  • Extreme sensitivity to foods and drinks that are hot or cold, which does not go away once finished
  • More than the normal amount of expected swelling
  • More than the normal amount of expected tenderness
  • A lump growing on the gums
  • A darkening of the tooth
  • Smelling a foul odor

What causes infection after a root canal?

A tooth may become re-infected for a number of different reasons. One possibility is that the permanent crown meant to add further protection against decay may have been delayed, giving bacteria a chance to re-infect the tooth. It is also possible the original seal after filling wasn’t sufficient to prevent bacterial contamination.

What can be done?

A tooth that becomes re-infected after a root canal is not hopeless. A second root canal may be able to be performed on the tooth. If the problem is more complex, an apicoectomy performed by an endodontist may be necessary.
