How do I know if my root canal is reinfected?

Can a tooth with a root canal become reinfected?

What happens when a root canal gets reinfected?

If infection does reoccur it doesn't mean the tooth is lost. It's possible a second root canal treatment can successfully correct any problems, especially those that may not have been detected the first time. More complex cases might also require the services of an endodontist, a specialist in root canals.

Can nerves grow back after root canal?

A root canal is necessary when the pulp tissue (nerves and blood vessels) inside a tooth either have become infected with bacteria or irreversibly inflamed (meaning they cannot heal themselves). The nerve inside a tooth has very limited ability to heal itself or regenerate.

Why does the tooth next to my root canal hurt?

There are a couple of reasons this may happen. First, though the nerve-filled “pulp” is removed from your tooth, there are still other nerves and sensitive tissues near the canal of your tooth, and these can be irritated and become swollen or inflamed after your endodontic treatment, causing some minor discomfort.

How often do root canals get reinfected?

The European Journal of Dentistry found that the overall success rate of a root canal and other endodontic treatment ranges from 86% to 98%. According to the study, various factors can contribute to failure, including the persistence of bacteria, untreated canals, or other complications.

What holds a tooth in place after a root canal?

While the tooth no longer contains living pulp tissue, it is secured in place by the periodontal ligament, which ensures it can continue to function like your other teeth after the pulp has been removed. While root canals may last a lifetime, there are some circumstances in which your tooth could need to be re-treated.

Why does my root canal hurt months later?
