Root canals are needed when the nerves and pulp inside the tooth is damaged or decayed. In order to save your tooth, the pulp, nerves and decay/bacteria need to be removed and replaced.
Signs and symptoms for possible root canal therapy:
- Abscess on the gums
- Sensitivity to hot and cold
- Severe tooth pain, swelling or tenderness
Reasons for a root canal:
- Injury or trauma to the tooth
- Decay has reached the tooth pulp
- Infection has developed inside the tooth
What does root canal therapy involve?
Your root canal will be performed by a dentist or over one or more appointments. An opening will be made at the top of the tooth and the pulp, nerve tissues and bacteria will be removed. The tooth is then sealed back up with a filling and crown.
Caring for teeth after a root canal:
You will be given detailed care instructions after your root canal appointment. You may experience increased sensitivity, but this will subside as the inflammation goes down.
