Root canal treatment – what happens
Inside the tooth is the pulp, a soft tissue containing nerves and blood vessels, among other things. Root canal treatment may be needed when the pulp cannot be preserved. The aim is to keep the tooth.
The examination determines the treatment
The dentist examines the tooth and assesses which treatment is suitable. Not all problems affecting the pulp require root canal treatment; in some cases, the pulp can be preserved with other treatment.
How root canal treatment works
- Anaesthetic and preparation. Treatment is usually carried out with a local anaesthetic. The tooth is protected with a rubber dam that keeps saliva away from the area.
- Cleaning. The dentist opens the tooth and removes the pulp tissue. The root canals are cleaned and shaped with small instruments and rinsed clean.
- Filling the root canals. The canals are filled with a material that seals them. The dentist checks the treatment using X-rays.
- Rebuilding the tooth. The tooth is rebuilt with a filling or crown. The choice depends on factors such as how much tooth remains and the forces acting on it.
How many visits are needed?
Sometimes treatment can be completed in one visit; sometimes several are needed. This depends on factors such as the tooth’s anatomy and the treatment required. The dentist gives you an individual plan.
Questions during and after treatment
Tell the clinician if you feel anxious and speak up if anything hurts during treatment. Your clinician will give you advice for afterwards and explain how the tooth should be followed up.
Contact your dental clinic if you have symptoms or questions about the treatment.
