This frustrating situation occurs when the filling leaks, allowing bacteria from your saliva to work their way in around the edges of the filling. Once inside the root canal , bacteria can create an infection within just a few days. There are a number of possible causes of pain after the completion of a root canal. After a root canal is complete no living nerve tissue remains inside the tooth , but nerve endings remain in the ligaments that attach the tooth to the surrounding bone.

These ligaments have nerve fiber associated with them that can feel pain. As a general rule, the more painful a tooth was before treatment, the more likely it is that you will experience a stronger tooth pain after the root canal therapy. The existing inflammation of the periodontal ligaments around the root tips of the infected tooth is the most common cause of tooth pain after root canal treatment.

Unfortunately, even after the root canal is complete a patient may continue to experience pain when biting or chewing. If the pain after root canal is intense, this could be a sign of complications and possibly of a root canal failure. In about one percent of the cases further treatment or even tooth extraction may be required to relieve the root canal pain. The pain is either more intense and or lasts longer after a stimulation like cold or chewing.
