Root canal treatment

Root canal treatment

A root canal procedure treats a damaged or infected pulp (nerve) tissue inside a tooth.  A dying pulp can sometimes be a very painful experience and our dentists will always be compassionate and gentle during this process.

Symptoms and Diagnosis

Through decay, cracks or injury, the pulp (nerve) tissue inside a tooth may become infected. Symptoms and signs include toothache, temperature sensitivity, broken or lost tooth structure, pain on pressure, or swelling.  Diagnosis is usually made with a pulp vitality test, percussion test and x-rays. Once diagnosed, a dying pulp has to be treated with either a root canal treatment or an extraction of that tooth. Our dentists will provide information and a quote regarding the procedure that is specific to the offending tooth.


Root canal treatment is usually dealt with in three main stages.  The first, or emergency stage, allows the tooth to be ‘drained’ of the bulk of the infection. The second, or debridement stage, involves the thorough cleaning and shaping of the individual canals within the tooth root, as well as placement of a medicated paste to control the rest of the infection. The third, or obturation stage, is when the tooth canals are sealed.  After root canal treatment is completed, a restoration is placed.  At times, a full-coverage crown is advised to provide adequate strength to prevent future fracturing of the tooth.
