How do I know if my root canal is healing?

One of the common questions after a root canal is how to know if it is healing properly. According to Dr. Jaqueline Allen, an endodontist with the Phoenix Endodontic Group, “Root canal healing is identified by the elimination of symptoms either immediately or over time, the elimination of swelling, and bone growth over the next six months to two years, in areas where abscesses have eliminated bone.”

Some signs that your root canal is healing well are:

  • You have no or minimal pain in your tooth and surrounding gums.
  • You have no sensitivity to hot or cold foods and drinks.
  • You have no swelling or tenderness in your jaw or face.
  • You have no pus or drainage from your gums or tooth.
  • Your tooth looks normal and does not change color.

Some signs that your root canal may not be healing well are:

  • You have persistent or severe pain that does not go away with painkillers.
  • You have increased sensitivity to hot or cold foods and drinks.
  • You have swelling or tenderness in your jaw or face that gets worse over time.
  • You have pus or drainage from your gums or tooth that has a bad odor or taste.
  • Your tooth looks darker or discolored.

Why is a Root Canal Needed?

A root canal is often necessary when the pulp inside a tooth becomes infected or inflamed. The pulp is a soft tissue that contains nerves, blood vessels and connective tissue and it can become damaged due to deep decay, trauma to the tooth or a cracked or chipped tooth. When the pulp becomes infected or inflamed, it can cause severe pain, discomfort and other symptoms such as sensitivity to hot and cold temperatures, swelling and tenderness.

A root canal procedure is needed to remove the infected or inflamed pulp and to prevent the spread of infection to other parts of the mouth or body. If left untreated, the infection can lead to the formation of an abscess which can cause even more pain and can potentially spread to other parts of the body. A root canal can save the affected tooth from extraction and relieve the pain and discomfort caused by the infection. With proper care and maintenance, a tooth that has undergone a root canal can last a lifetime.
