A root canal therapy is performed when the nerve tissue of the tooth is damaged or infected. Nerve (pulp) of the tooth is very sensitive and once infected, unlike the other part of the human body, it does not repair by itself. In order to maintain the
tooth, the pulp tissue has to be carefully removed from the tooth. Firstly, the tooth is anaesthetised and the pulp is removed and cleaned. Then internal hollow space (canal) will be filled with filling material and then, crown will be restored to prevent further damage of the root.
