What are the signs that a root canal has failed and requires retreatment?

Root canal retreatment may be required if your tooth isn't healing as expected following root canal therapy. Some of the signs to watch for that may indicate a problem include:

  • Pain and tenderness in the affected tooth and surrounding gums
  • Swelling in the gums in the area of the affected tooth
  • Sensitivity in the tooth that doesn’t fade
  • Visible infection in a follow-up x-ray

Because reinfection may occur soon after root canal therapy or years or even decades later, it is important to continue getting regular twice yearly examinations so that any problems that develop can be caught early.
