What does it involve?
The affected pulp tissue is removed, the root canal system is cleaned and disinfected, and it is then sealed.
The crown of the tooth is restored afterwards; depending on how much tooth structure remains, a prosthetic restoration may be recommended.
When is it recommended?
Situations in which root canal treatment may be indicated:
- spontaneous or night-time pain
- prolonged sensitivity to heat
- deep decay that has reached the pulp
- dental trauma
- a tooth that has changed colour
What to expect
Treatment is carried out under local anaesthetic and may require one or more appointments. Some tenderness on chewing in the following days is common and gradually reduces.
Success is influenced by canal anatomy, the extent of infection and the final restoration of the tooth.
Frequently asked questions
Is root canal treatment painful?
The procedure is performed under local anaesthetic. The associated discomfort is usually less than the pain that prompted the visit.
Why are several appointments sometimes needed?
Canal anatomy and the presence of infection may require staged treatment, with medication placed inside the canals between visits.
Will the tooth need a crown afterwards?
It depends on how much healthy tooth structure remains. The recommendation follows clinical assessment.
