Root Canal treatment is a common dental procedure used to treat infection of the root canal system. It is a skilled procedure that is time consuming and it may require several appointments. The infection is caused by bacteria that already live in the mouth and are able to penetrate the tooth because of decay, leaky fillings or damage from trauma. The aim of the treatment is to remove the bacteria and infected contents of the root canals to allow thorough cleaning. The process of clearing the infection will protect the tooth from subsequent infections once this is achieved the root canals are filled and sealed.
