What is a Reinfected Root Canal?

A reinfected root canal happens when bacteria re-enter a tooth that has already undergone root canal therapy. This may be due to incomplete cleaning during the initial procedure, a damaged filling or crown, or new tooth decay that opens a path for bacteria to the inner tissue.

about Reinfected Root Canal

Common Causes

Several factors can lead to a reinfected root canal:

  • Incomplete removal of bacteria during the first root canal
  • Cracked or leaking restorations (e.g., crowns or fillings)
  • New decay around a treated tooth
  • Complex or curved root canals that were missed
  • Trauma that compromises the integrity of the seal

Symptoms to Watch For

Watch out for these warning signs that may indicate your root canal has become reinfected:

  • Persistent or returning toothache
  • Swelling of the gums or face
  • Tenderness or pain when chewing
  • Gum boils or pus near the affected tooth
  • Discoloration or darkening of the tooth
  • A bad taste or odor in the mouth

Diagnosis and Evaluation

Diagnosing a reinfected root canal starts with a clinical exam and imaging, including:

  • Digital X-rays to detect changes in bone around the tooth root
  • Evaluation of previous root canal work and restorations
  • Tests to check tooth sensitivity and surrounding gum tissue
  • Review of symptoms and history of pain or swelling

Treatment Options

  • Nonsurgical Re-Treatment: Removal of old filling material, cleaning, disinfection, and resealing of the root canals.
  • Apicoectomy: Surgical removal of the infected root tip if re-treatment is not viable.
  • Tooth Extraction: Recommended when the tooth cannot be saved; may be followed by an implant or bridge to restore function.
