Why root canal treatment may be recommended
Inside each tooth is soft tissue called the pulp. If the pulp becomes inflamed or infected because of deep decay, a crack, trauma or another problem, a dentist may recommend root canal treatment when the tooth is suitable to be preserved.
Not every painful tooth needs root canal treatment, and not every tooth can be saved. An examination and appropriate imaging are important before a treatment decision is made.
What the procedure generally involves
The purpose of treatment is to clean and disinfect the affected root canal system and then seal the space. Local anaesthetic is commonly used, and the number of visits can vary according to the tooth and clinical situation.
- Assessment and diagnosis
- Local anaesthesia when appropriate
- Cleaning and shaping the root canal system
- Disinfection and sealing
- Restoration of the tooth after treatment
What happens after treatment
Some tenderness can occur after treatment. The dentist will explain after-care and whether the tooth needs a filling, crown or another restoration to protect it.
If pain or swelling becomes severe, worsens unexpectedly or you are concerned about recovery, contact the treating dentist for advice.
