Does a second root canal hurt

A second root canal, called nonsurgical retreatment, is performed with local anaesthetic, although the tooth may feel tender afterward.

This question describes a specific dental material, symptom, procedure, or price factor that needs to be separated from similar everyday terms.

Use the dental method appropriate to the material or symptom, follow product directions, and avoid improvised treatment that can damage teeth, gums, or appliances.

Arrange an examination for persistent pain, swelling, bleeding, altered function, or a problem that keeps returning. Urgent care is needed for facial swelling, fever, or difficulty swallowing or breathing.

Ask what structure is affected, which examination or imaging is needed, and whether treatment, monitoring, or a safer alternative addresses the underlying cause.
