Gingivitis means inflammation of the gums, or gingiva. It commonly occurs because a film of plaque, or bacteria, accumulates on the teeth. Gingivitis is a non-destructive type of periodontal disease that results in symptoms such as redness, swelling and bleeding. Very often, early stages of periodontal disease are effectively treated with non-surgical periodontal therapy. This involves the therapeutic and systematic removal of bacterial plaque and tartar which is present at and below the gum line. Left untreated gingivitis can progress to periodontitis. Periodontitis is a serious gum infection and leads to the destruction of the bone supporting the teeth and can eventually lead to tooth loss and other serious health complications.
