A root canal removes inflamed or infected tissue from inside a tooth so the tooth itself can stay. Here is when it may be needed.

Watch for these signs

Not every sign means a root canal, but each deserves an exam.

  • Sensitivity to hot or cold that lingers after the drink is gone
  • Sharp or throbbing pain when chewing
  • A pimple-like bump, swelling, or tenderness on the gum near a tooth
  • A tooth that has darkened

Sometimes there is no pain

An infection can be quiet. X-rays at routine visits sometimes reveal a problem before you feel anything.

Why acting early matters

Untreated infection can spread and may cost the tooth. Call Fievet Dental at 770.979.3760 and Dr. Ruchika Desai will help you decide on next steps.
