While some pain and tenderness is common after a root canal, severe pain and pressure that lasts more than a few days can indicate a problem that needs to be addressed by a dentist, according to WebMD. Possible causes for severe pain include a crack in the root of the tooth, defective dental restoration that has allowed bacteria to enter or improper fitting of the new crown.
