Root canal treatment is performed to save a tooth that is infected or has a large lesion affecting the nerve. The procedure consists of removing the infected pulp (nerve) and leaving the canals free of bacteria. Canals are then sealed to prevent any future contamination.
Many patients have the misconception that a root canal is a very painful procedure. The truth is a root canal removes tooth pain. With modern dentistry, a root canal procedure should be painless just like a filling.
An infected tooth may not have symptoms, however, signs indicating you may need a root canal include:
- Severe toothache or pain upon chewing
- Continued sensitivity/pain to hot or cold temperatures (after the heat or cold has been removed)
- Discoloration (darkening) of the tooth
- Swelling or bump on tissue near the affected tooth
