Root Canals

When the nerve of a tooth becomes damaged either because of a large cavity or because of trauma, root canal treatment is necessary to maintain the tooth.  Root canal treatment involves the removal of the damaged nerve and blood supply to a tooth and then filling the inside portion of the tooth with “filling” material before restoring the tooth with a crown.

During root canal treatment, a patient should expect to receive appropriate anesthesia for comfort.  It is then necessary to enclose the tooth with a rubber sheet, called a rubber dam, to prevent contamination of the inside of the tooth while the nerve is being removed.  After placement of the rubber dam, a series of files along with special medications for disinfection are used to remove the nerve and shape the inside of the tooth.  The inside of the tooth is then filled with a plasticized filling material and the top part of the tooth is then restored.
