Quick Answer
Many teeth that seem beyond help can still be saved with root canal or retreatment, which removes infection and seals the canal system. Specialists review each case together and recommend saving the tooth only when it is realistic. If extraction is the more sensible option, they explain that honestly before any treatment begins.
Pain can return after a root canal when fine or curved canals were missed during the first treatment, or when the tooth was never protected with a crown and became reinfected. Root canal retreatment reopens the tooth to re-clean and reseal the canal system. Whether retreatment can save the tooth is confirmed by examination and X-ray.
