Endodontics
Endodontic treatment is most often referred to as root canal treatment and consists in cleaning each subsequent root canal of a tooth. The canals are located inside of the tooth root, which are, similarly to the chamber, filled with a dental pulp, i.e. nerves and blood vessels.
Pulpitis in its advanced stage is irreversible and requires its complete removal from the inside of the infected tooth.
After properly applied root canal treatment, the tooth is dead, however, it does not cause pain, and after the crown has been restored, it may serve many years.
