What Is a Root Canal Treatment?

Root canal treatment (RCT) is a procedure used to remove infected or inflamed pulp tissue from inside a tooth, clean and shape the canal system, and seal it to prevent further infection. It allows a badly damaged or infected tooth to be saved instead of extracted.

Signs You Might Need a Root Canal

  • Severe, lingering tooth pain, especially with hot or cold stimuli.
  • Swelling or a pimple-like bump on the gums near the affected tooth.
  • Darkening or discoloration of the tooth.
  • Tenderness to touch or chewing pressure.

Step-by-Step Root Canal Procedure

  1. Diagnosis: Clinical examination and a periapical radiograph to assess the extent of infection.
  2. Local Anaesthesia: The area is numbed completely so the procedure is pain-free.
  3. Access Cavity Preparation: A small opening is made in the crown of the tooth to reach the pulp chamber.
  4. Pulp Removal and Cleaning: Infected pulp tissue is removed and the canals are cleaned and shaped using specialised instruments.
  5. Disinfection: Canals are irrigated with antimicrobial solutions to eliminate bacteria.
  6. Obturation: The cleaned canals are filled and sealed, typically with gutta-percha and sealer.
  7. Restoration: A filling or crown is placed to restore the tooth's shape and function, since root-canal-treated teeth can become brittle over time.

Is Root Canal Treatment Painful?

Modern root canal treatment, performed under proper anaesthesia, is generally no more uncomfortable than a routine filling. Most reported pain associated with root canals actually comes from the underlying infection before treatment, not the procedure itself.

Recovery and Aftercare

  • Mild soreness for a few days is normal and manageable with prescribed medication.
  • Avoid chewing hard foods on the treated side until a permanent crown is placed.
  • Maintain good oral hygiene and attend follow-up visits as advised.

Conclusion

Root canal treatment is a highly effective way to save a natural tooth and relieve pain caused by pulp infection. Early diagnosis and timely treatment significantly improve the long-term prognosis of the tooth.
