What is it?
The pulp is the tissue inside the tooth containing nerves and vessels. After deep decay, a crack or trauma it can become inflamed. In root canal treatment the pulp is removed, the canals are shaped and filled with a suitable material.
Treatment is done under local anaesthesia and may take one or more sessions. Afterwards the tooth is protected with a filling or crown.
The course depends on the tooth's anatomy and the extent of inflammation; the treatment choice is made together after X-ray and examination.
Who is it assessed for?
- People with prolonged, throbbing toothache
- Those with marked sensitivity to heat
- Teeth with swelling or an abscess around them
- Teeth that changed colour after trauma
- Teeth whose deep decay has reached the pulp
