Root canal treatment removes infected or inflamed pulp from inside a tooth, disinfects and shapes the canals, and seals them to reduce the risk of reinfection. It can preserve a tooth that might otherwise need extraction.
What root canal treatment is designed to address
Under local anaesthetic, the dentist accesses the tooth, removes affected tissue, cleans the canal system and places a filling. Treatment may take more than one visit. A crown is often considered when the remaining tooth is weak.
Who may consider it
Persistent toothache, sensitivity, swelling, a cracked tooth or an abscess can indicate pulp disease, but diagnosis requires examination and usually imaging. Antibiotics alone do not remove infected pulp from inside the tooth.
A decision should follow a face-to-face examination, a review of medical history and a realistic conversation about alternatives. Photographs, measurements or imaging may be used when they genuinely help the clinical plan.
Planning a safe, personal treatment
A complete dental examination should come before cosmetic decisions. Gum health, decay, bite, enamel, existing restorations and radiographs where indicated help determine whether treatment is appropriate and whether a more conservative option is available.
- Treat active decay or gum disease first.
- Ask which parts of the tooth are altered and whether the change is reversible.
- Agree on shade, shape, bite and maintenance before treatment starts.
Recovery and follow-up
Short-lived sensitivity or gum tenderness may occur after some dental procedures. Follow-up is important when the bite feels high, pain is increasing or a restoration feels loose. Daily brushing with fluoride toothpaste, cleaning between teeth and regular examinations protect both natural teeth and restorations.
Individual recovery varies. Written aftercare instructions take priority over general timelines, and new severe pain, breathing difficulty, heavy bleeding, fever or another unexpected symptom should be reported promptly to the treating team.
Risks and limitations to understand
Soreness usually improves after treatment. Increasing swelling, fever, severe pain or a lost temporary restoration should prompt contact with the dentist.
- Post-treatment tenderness or swelling
- Persistent infection or a missed complex canal
- Instrument or restoration complications
- Tooth fracture or the need for retreatment or extraction
Questions worth asking at consultation
- Is there active disease that should be treated first?
- What is the most conservative suitable option?
- How will this affect my bite and healthy tooth structure?
- What maintenance and replacement may be needed over time?
