What Happens During a Root Canal in London, Ontario?

Quick answer: A root canal removes infected or damaged pulp from inside a tooth, cleans and disinfects the canal, then seals it — relieving pain and saving the natural tooth. At Longo Dentistry in London, Ontario, most root canals are completed in one to two visits.

Signs You May Need a Root Canal

  • Sharp or lingering pain when biting or chewing
  • Sensitivity to hot or cold that lasts after the stimulus is removed
  • Swelling or tenderness in the gums near a specific tooth
  • A darkening tooth

The Procedure, Step by Step

  • Numbing the area for a comfortable procedure
  • Removing infected pulp from inside the tooth
  • Cleaning and shaping the canal
  • Sealing the tooth (often followed by a crown for strength)

Why Delaying Makes It Worse

An untreated infected tooth can lead to abscess, bone loss around the root, and eventually loss of the tooth altogether — root canal treatment now is almost always simpler and less costly than the alternative later.

FAQs

Is a root canal painful?
