Even though root canals have a very high success rate, when a root canal fails to heal, or there is a recurrent infection, you may need a Re-RCT or root canal re-treatment.
A Re-RCT usually results due to a particularly virulent infection or inflammation despite your dentist’s best efforts. Other reasons include a fractured crown or tooth, missed root canals and left-over pulp tissue.
How do I know if a root canal has failed?
Common signs of a failed root canal treatment include:
- Discomfort when biting
- Tenderness or swelling near the tooth
- A pimple-like bump inside the mouth
How does a Re-RCT differ from a root canal?
A root canal re-treatment is very similar to a root canal treatment. However, a Re-RCT requires a few extra steps and normally two visits to the dentist. However, to make the final restoration for the tooth, it may require 2 more visits. Most root canal treated teeth are restored with crowns.
During the first visit, the dentist will remove all the root canal filling materials then fill the void with an antibacterial paste. The tooth is closed with a temporary filling.
The paste is left in place to kill as much bacteria as possible.
During the second visit, the calcium hydroxide anti-bacterial paste is removed, and the canal area cleaned and shaped, and a new root canal performed.
