Root Canal

Saving Your Tooth and Relieving Pain
A root canal treatment is a dental procedure designed to save a tooth that would otherwise need to be extracted. It involves removing the infected or necrotic nerve inside the tooth, cleaning and disinfecting the canals, then sealing them to prevent future infection. Once the root canal is completed, the tooth is restored with a composite filling or, ideally, a dental crown to reinforce its strength and function.
This treatment allows you to keep your natural tooth, avoid extraction, and prevent more serious complications.
Why is a root canal necessary?
A root canal is required when bacteria reach the center of the tooth (the pulp), often due to:
- a deep cavity
- a crack or fracture
- trauma
- a leaking or failing restoration
When the pulp becomes infected or necrotic, pain can intensify and the infection may spread to the bone or surrounding tissues. A root canal stops the infection, eliminates the pain, and preserves the tooth.
How long does the procedure take?
The duration depends on the number of canals in the tooth (between 1 and 4). On average, a root canal appointment lasts 60 to 120 minutes.
Some teeth may require a second visit, especially when:
- the infection is extensive
- the canals are difficult to access
- the tooth has complex anatomy
Your dentist will explain the recommended treatment plan based on your specific case.
Does a root canal hurt?
Despite common misconceptions, a root canal does not cause pain — it relieves it. The procedure is performed under local anesthesia, making it comfortable for most patients.
It is normal to experience mild sensitivity for a few days afterward, which can be managed with over‑the‑counter pain relievers.
In cases of significant infection or abscess, a stronger anesthetic or a short course of antibiotics may be recommended before the procedure to ensure optimal comfort.
