Root canal is a valuable dental procedure used to treat and preserve teeth with an infected or dying nerve. The pulp is the live portion of the tooth that extends into the root containing nerve endings and tissue. If the nerve becomes infected or exposed patients may experience discomfort and/or swelling. Root canal (endodontic) procedures remove the affected tissue within the tooth and is sealed with gutta-percha (a dental filling material). The portion of the remaining tooth is then restored at a future appointment, most frequently with a crown, providing function, durability and a natural appearance.
Take heed for those requiring root canal, the procedure is usually painless and with modern advancements in technology and good anesthetic normally goes without incident.
