Root canal treatment saves teeth that have become severely infected or decayed. With modern anaesthetics and rotary techniques, the procedure is virtually painless—and far preferable to losing the tooth altogether.
When the nerve inside a tooth becomes inflamed or infected, you may experience severe sensitivity, throbbing pain, or swelling. Root canal therapy removes the damaged tissue, disinfects the canals, and seals the tooth so it can function normally again.
Signs you may need root canal treatment
- Prolonged sensitivity to hot or cold
- Severe toothache, especially when biting
- Swelling or tenderness in the gums near a tooth
- Darkening of a single tooth
- A pimple-like abscess on the gum
The treatment process
- Diagnosis — clinical examination and X-rays to confirm infection
- Anaesthesia — the tooth is fully numbed for comfort
- Canal cleaning — infected tissue removed and canals shaped
- Sealing — canals filled and the tooth restored
- Restoration — a crown is often recommended for long-term strength
After your treatment
Mild tenderness for a few days is normal and managed with standard painkillers. Most patients return to normal activities the next day. A follow-up crown protects the treated tooth from fracture—your dentist will advise on timing.
Frequently Asked Questions

No. The tooth is numbed before treatment and most patients feel immediate relief from prior pain.
How successful is root canal treatment?
Success rates exceed 90% for most teeth. With a crown and good oral hygiene, treated teeth can last many years.
Is extraction a better option?
Saving your natural tooth is usually preferable. We discuss all options including implants if the tooth cannot be saved.
