Modern root canal treatment is performed with local anaesthetic. The aim is to relieve pain and preserve a tooth, not cause discomfort.
1. Examination and X-ray
The dentist identifies the source of symptoms, evaluates whether the tooth can be restored, and studies the root shape and surrounding bone.
2. Anaesthetic and isolation
Local anaesthetic numbs the area. A small protective sheet called a rubber dam isolates the tooth and keeps the treatment field clean.
3. Cleaning the root canals
The inflamed or infected tissue is removed. Fine instruments and disinfecting solutions clean and shape the internal spaces. Magnification can help the dentist find complex anatomy.
4. Sealing and restoration
The cleaned canals are filled and sealed. The tooth then needs a strong final restoration—often a crown for back teeth—to reduce the risk of fracture.
After treatment
Mild tenderness can occur for a few days. Follow the dentist’s instructions and return promptly if swelling, severe pain, or other unexpected symptoms develop.
