Medical Definition of PERIODONTITIS

: inflammation of the periodontium and especially chronic inflammation that typically follows untreated gingivitis and that results in progressive destruction of the periodontal ligament, formation of pockets around the teeth, and resorption of alveolar bone chiefly in a horizontal direction with loosening or loss of teeth—called also pericementitis

periodontitis

noun    (Concise Encyclopedia)

Inflammation of soft tissues around the teeth (see tooth). Poor dental hygiene leads to deposition of bacterial plaque on the teeth below the gum line, irritating and eroding nearby tissues. If it is not treated, the gum margin recedes, exposing the roots of the teeth. The process eventually involves the bone anchoring the teeth, which loosen and may fall out. Removal of all plaque deposits and affected soft tissues can arrest but not reverse bone deterioration.
