Root canal therapy is the process of removing inflamed or infected pulp tissue (the living tissue inside the tooth) from the space inside your tooth – called the root canal system. The canal is then filled with materials designed to prevent infection from recurring and restore the tooth to its full function.
A successful root canal treatment lets you keep your tooth rather than having it extracted. Keeping your tooth helps to prevent adjacent teeth from drifting out of line, causing further problems. Some root canaled teeth do require a crown once the root canal has settled.
Reasons for requiring a root canal:
- Decay has reached the tooth pulp (the living tissue inside the tooth)
- Infection or abscess have developed inside the tooth or at the root tip
- Injury or trauma to the tooth causing a crack in the tooth structure
Symptoms or signs for root canal therapy may include:
- Minimal to severe pain
- Tooth discoloration
- Sensitivity to hot and col
- Swelling and irritation in the surrounding gum tissue.
Sometimes no symptoms are present.
