A root canal procedure is performed when the nerve of the tooth becomes infected or the pulp becomes damaged. The nerve is inside the tooth and travels from the tip of the tooth’s root into the pulp chamber, which also contains blood vessels and connective tissue that nourish the tooth. During a root canal procedure, the nerve and pulp are removed, and the inside of the tooth is cleaned and sealed. A tooth’s nerve is not vitally important to a tooth’s health and function. The presence or absence of a nerve will not affect the day-to-day functioning of the tooth.
The discomfort experienced in the period leading up to seeking dental care is truly painful. Most people are relieved that the root canal procedure itself is painless. In most situations your dentist will recommend a crown to be placed after your root canal.
