What should I do if the pain returns after getting an emergency root canal?

Published 9 May 2026

If pain returns after an emergency root canal, you should contact your dentist for an urgent evaluation. While mild soreness for a few days is normal, recurring or worsening pain may indicate a reinfection, a missed canal, or a cracked tooth. Professional assessment is necessary to determine if you require further cleaning or retreatment.

Seek immediate dental or medical attention if you experience:

  • Severe facial or neck swelling.
  • High fever or chills.
  • Difficulty breathing or swallowing.
  • Pus or drainage around the gums.
  • Inability to manage pain with over-the-counter medication.
