A root canal (endodontic treatment) is necessary to repair and save a badly damaged or infected tooth. The procedure involves removing the damaged area of the tooth (the pulp), cleaning and disinfecting it and then filling and sealing it. The common causes affecting the pulp are a cracked tooth, a deep cavity, repeated dental treatment to the tooth or injury. Some of the main indicators of infection in the tooth can include sensitivity to hot or cold food and drinks, pain, swelling or a substance oozing from the affected tooth.

The goal of root canal treatment is to save the tooth and prevent it from future infection. If the root canal treatment is not completed, the infection may spread and the tooth may need to be extracted. Depending on the strength of the remaining structure post treatment, the tooth will require either a crown or a filling.

4 Main Steps of a Root Canal

X-ray – Your dentist will take X-rays or examine existing X-rays to show where the decay is located.

Anaesthesia – Local anaesthetic is administered to the affected tooth, to numb the area and make the patient feel at ease.

Pulpectomy – An opening is made in the top of the tooth and the diseased pulp is removed.

Filling – The roots that have been opened are filled and sealed off with cement. The tooth is then covered using a permanent filling or a crown to give it durability and protection.
