A root canal can save a damaged or infected tooth, and when done correctly, it can last for many years. But like any dental treatment, it’s not always permanent. Over time, wear, reinfection, or other issues can require retreatment or even replacement of the tooth.
How do you know when it’s time to update your root canal? Here’s what to watch for.
How Long Does a Root Canal Last in Chattanooga?
The lifespan of a root canal varies, but most treated teeth last 10-20 years with good oral care. However, certain factors can shorten that timeline, such as:
- Not getting a protective dental crown after treatment
- New cavities forming around the treated tooth
- Cracks or fractures in the tooth
- Poor oral hygiene leading to reinfection
Signs That Your Root Canal May Need Updating
If your previously treated tooth starts showing any of these symptoms, you may need a retreatment:
- Pain or Sensitivity Returns – A root canal should eliminate pain, so if discomfort returns, it could indicate reinfection or incomplete treatment.
- Swelling Around the Tooth or Gums – This can be a sign that bacteria have re-entered the tooth, leading to inflammation.
- A Loose or Cracked Crown – If the crown covering your treated tooth becomes loose or damaged, the tooth underneath can be exposed to bacteria.
- New Decay Near the Treated Tooth – Even a tooth that had root canal treatment can still get cavities, which may lead to further complications.
- Discoloration or Darkening of the Tooth – A noticeable change in color may mean that the internal tooth structure is deteriorating.
