Did you know that each tooth contains a long, thin strand of dental pulp that provides the tooth with nutrients and nerves and extends down to the tooth’s root? If the pulp becomes infected or injured, nerves of the tooth die and often, without endodontic treatment, the tooth would have to be removed. Root canals are designed to save such damaged teeth. During the procedure (after the tooth is numb), a gap is drilled into the tooth’s crown and pulp chamber, diseased pulp is reshaped or removed, and the tooth is permanently sealed with a gold, porcelain, or tooth-colored crown.
