Root canal treatment, also known as endodontic therapy, is a dental procedure that treats infection or inflammation inside the tooth. It is often necessary when the tooth pulp (the soft tissue inside the root canal) becomes damaged due to deep decay, trauma, or repeated dental procedures.

Rather than extracting the tooth, root canal treatment removes the infected pulp, disinfects the area, and seals it—allowing the natural tooth to be preserved and function normally.

Signs You May Need a Root Canal

  • Severe toothache, especially when chewing or applying pressure

  • Sensitivity to hot or cold that lingers

  • Swelling or tenderness in the gums

  • Darkening of the tooth

  • Presence of an abscess or pus

How the Procedure Works

  1. Examination & Imaging: X-rays are taken to assess root damage.

  2. Anesthesia: The area is numbed for a painless experience.

  3. Cleaning the Canals: Infected tissue is removed and canals are shaped.

  4. Disinfection & Filling: The canals are sterilized and filled with a biocompatible material.

  5. Restoration: A crown or filling is placed for strength and function.

Advantages of Root Canal Treatment

  • Saves the natural tooth

  • Restores chewing and biting ability

  • Prevents further infection and abscesses

  • Preserves jawbone and tooth alignment

  • High success and longevity rate


Top 10 FAQs About Root Canal Treatment

  1. Is root canal treatment painful?
    No, with modern anesthesia it’s nearly painless.

  2. How long does it take?
