What is gingivitis? 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, but untreated gingivitis can progress to periodontitis. This is more serious and can eventually lead to loss of teeth. Signs and symptoms In mild cases of gingivitis, there may be no discomfort or noticeable symptoms. Signs and symptoms of gingivitis might include: bright red or purple gumstender gums that may be painful to the touchbleeding from the gums when brushing or flossinghalitosis, or bad breathinflammation, or swollen gumsreceding gumssoft gums Causes The most common cause of gingivitis is the accumulation of bacterial plaque between and around the teeth. The plaque triggers an immune response, which, in turn, can eventually lead to the destruction of gingival, or gum, tissue. It may also, eventually, lead to further complications, including the loss of teeth. Dental plaque is a biofilm that accumulates naturally on the teeth. It is usually formed by colonizing bacteria that are trying to stick to the smooth surface of a tooth. These bacteria might help protect the mouth from the colonization of harmful microorganisms, but dental plaque can also cause tooth decay, and periodontal problems such as gingivitis and chronic periodontitis, a gum infection. When plaque is not removed adequately, it can harden into calculus, or tartar, at the base of the teeth, near the gums. This has a yellow color. Calculus can only be removed professionally. Plaque and tartar eventually irritate the gums, causing gum inflammation around the base of the teeth. This means that the gums might easily bleed. Other causes and risk factors Changes in hormones: This may occur during puberty, menopause, the menstrual cycle, and pregnancy. The gingiva might become more sensitive, raising the risk of inflammation. Some diseases: Cancer, diabetes, and HIV are
