Dental Cavities (cont..)

Treatment of a small and shallow cavity usually involves a dental filling. Treatment of a larger cavity involves an onlay or crown. Treatment of a cavity that has penetrated and injured the pulp requires either a root canal procedure or extraction of the affected tooth. Injury to the pulp can lead to death of pulp tissue, resulting in tooth infection (dental abscess). The treatment of an infected tooth is either removal of the tooth or a root canal procedure. The root canal procedure involves removing the dying pulp tissue (thus avoiding or removing tooth infection) and replacing it with an inert material. The procedure is used in an attempt to save the dying tooth from extraction.
