Root canal therapy is needed when the nerve of a tooth is affected by decay or infection. In order to save the tooth, the pulp (the living tissue inside the tooth), nerves, bacteria, and any decay are removed. The space is filled with special, medicated dental materials, which restore the tooth to its full function.
Signs and symptoms for possible root canal therapy:
- Abscess (or pimple) on the gums
- Sensitivity to hot and cold
- Severe toothache pain
- Swelling and/or tenderness
- Sometimes, no symptoms are present
