So long as you practice good dental hygiene at home and see your dentist at least twice a year, most teeth that have had root canals can last you as long as intact teeth. However, sometimes, these treated teeth can fail over time. This can mean developing pain months, even years after treatment. Should this happen, the solution may be root canal retreatment.

Poor healing can be caused by numerous factors, including:
- Narrow or curved canals not treated with the original root canal.
- Complicated canal anatomy that the doctor was unable to detect during the first root canal.
- Poor seal of the crown, allowing saliva and bacteria to enter the tooth.
Other cases that indicate root canal retreatment are needed:
- New decay that risks exposing the filing material.
- A loose or broken crown.
For retreatment, the tooth is reopened, and the filling material is removed to clean the canals and examine the inside of the tooth. After disinfecting and filling the canals, the teeth are sealed with an adequate permanent restoration.
