With proper care and dental hygiene, your teeth that have had endodontic treatment may last a lifetime. However, occasionally a tooth that has received treatment may fail to heal or pain may continue to exist. Every root canal case is different and unique. Your dentist will take the time to discuss their findings with you and provide you with other options. In some instances, your dentist may recommend a root canal retreatment, which is almost identical to the original root canal procedure. Whenever possible, it is always best to save your natural tooth.
Improper healing is due to:
- Complicated canal anatomy went undetected during initial treatment
- Curved or narrow canals that were not treated during initial treatment
- Infection from new decay that is exposed to the root canal
- Cracked or loose filling/crown can expose the tooth to infection
- Restoration did not prevent salivary contamination to the inside of the tooth
- Delayed replacement crown or other restoration
