A root canal is a procedure used to repair and save a tooth that is decayed or has become infected. The term root canal describes the cavity within the center of the tooth. Within the tooth there is a nerve and pulp, both need to be removed and the inside of the tooth needs to be cleaned and sealed. Without proper treatment the tissue surrounding the tooth can become infected and an abscess may form.
Fortunately, a tooth’s nerve is not vital to the health of the tooth and will not affect the day-to-day operation of the tooth. The only function of the nerve is sensory to feel hot or cold.
