Root Canal Therapy
This can be caused by a number of reasons:
- Bacteria from a deep cavity causes infection
- Tooth is injured and the blood supply is ruptured or the nerve is damaged
- Tooth is fractured which exposes the tooth to bacteria found in the mouth
- Severe gum disease causes infection to the pulp
Root canal therapy involves removal of the pulp tissue and cleaning out the pulp chamber and canals. Once the area has been cleaned, medicine is then placed in the tooth and it is temporarily sealed to prevent bacteria from re-entering the tooth. Then the outer portion of the tooth must be restored.
