Root canal treatment

Quick answer

What is this treatment?

Root canal treatment treats inflamed or dead nerve tissue inside a tooth. The dentist cleans, disinfects and seals the root canals. The goal is to treat pain and infection and preserve the natural tooth where possible.

When it may be needed

• Severe, throbbing or persistent toothache.
• Pain with hot, cold, biting or pressure that does not settle quickly.
• Swelling, a gum boil or bad taste.
• Deep decay, a crack or trauma that has damaged the nerve.

What to expect

• We examine the pain and often take an X-ray.
• Treatment is usually carried out with local anaesthetic.
• The canals are cleaned, disinfected and filled.
• Afterwards, a filling or crown may be needed to protect the tooth.

Preparation and aftercare

• Call the same day with swelling, fever or rapidly increasing pain.
• Tell us which medicines you use and any medical details.
• Temporary soreness can occur after treatment; follow your dentist's advice.
• Have the final restoration placed in time if it is needed.
