Endodontics · single question

A tooth with an INCOMPLETE root canal filling (canals not obturated to length, done ~6 months ago) now has pain. The most appropriate management is:

  1. Nonsurgical endodontic retreatment
  2. Continued observation only
  3. Immediate extraction
  4. Prescribe antibiotics indefinitely
Show answer and explanation

Correct answer: A. Nonsurgical endodontic retreatment

  • A. Correct. A symptomatic tooth with inadequate (short/incomplete) obturation has persistent infection; nonsurgical retreatment to properly clean, shape, and obturate the canals is indicated.
  • B. Observation alone leaves the symptomatic infected canal untreated.
  • C. Extraction is premature when the tooth is restorable and retreatable.
  • D. Antibiotics do not resolve an under-filled, infected canal — definitive treatment is needed.

Note: Although some teach waiting ~1 year to judge healing of an asymptomatic case, ongoing PAIN with inadequate obturation warrants retreatment rather than waiting.
