What is Root Canal Treatment?

A root canal procedure is done to help save a tooth from severe infection or decay. During the process, the tooth’s nerve and pulp are removed, and the inside of the tooth is cleaned.

Why do I need a Root Canal?

If the tooth nerve and pulp are damaged or infected due to decay, they begin to break down. Bacteria and debris may result in the formation of an abscess. An abscess is the formation of pus, and if left untreated, it can cause swelling, pain in the head, neck, and cheek as well as bone loss near the tip of the tooth roots.

What is done during a Root Canal procedure?

The dentist verifies that the tooth is infected by means of clinical tests and an X-ray. A local anaesthetic is given to numb the tooth and the entire nerve tissue is removed. The inside of the canal is shaped and sterilised to prevent new bacterial growth. The procedure takes 1-3 sessions. An inert material, the most common being gutta percha, a natural product, is used to hermetically seal the empty canal because it does not allow bacteria to grow.
