Periodontitis is an advanced form of gum disease in which the tissues and bones that support the teeth are damaged by the buildup of bacterial plaque. If periodontitis is not treated, teeth can become loose and may fall out or need to be removed.

Treatment for periodontitis includes a cleaning method called root planing and scaling that removes plaque and tartar buildup both above and below the gum line. Antibiotics may be needed to help get rid of the infection. If gum disease is severe, surgery may be required.
