What is it?
Deep decay, a crack or a knock can inflame the nerve and blood vessels inside a tooth (the pulp). Root canal treatment removes this tissue, shapes and disinfects the canals and seals them. The aim is to keep the tooth instead of extracting it.
Who is it for?
- People with lingering sensitivity to hot or cold, or throbbing pain
- People with deep decay or a broken tooth
- People who notice swelling or an abscess in the gum
The process
- 1
Diagnosis
Examination and X-rays are used to assess the tooth and the root tip.
- 2
Cleaning the canals
Under local anaesthesia the inflamed tissue is removed and the canals are shaped and rinsed.
- 3
Sealing
The canals are sealed with a filling material. For some teeth this is done in a second session.
- 4
Restoring the tooth
The crown of the tooth is rebuilt with a filling or, if needed, a cap.
Aftercare
- Do not eat until the anaesthetic has worn off.
- Avoid chewing hard foods on that side until the final restoration.
- Mild tenderness for a few days is normal; call the clinic if pain or swelling increases.
Frequently asked questions
Is root canal treatment painful?
It is done under local anaesthesia. You may feel mild tenderness for a few days afterwards.
How long does a root-treated tooth last?
With a good restoration and regular care it can last many years. The tooth’s condition and your habits affect the outcome.
Wouldn’t extraction be easier?
Keeping your own tooth is usually better for chewing and for the neighbouring teeth. You can weigh the options with your dentist.
