Gingivitis is a form of periodontal disease. Periodontal disease is when inflammation and infection destroy the tissues that support the teeth, including the gingiva (gums), the periodontal ligaments, and the tooth sockets.

 

Gingivitis is caused by the long-term effects of plaque deposits. Plaque is a sticky material that develops on the exposed portions of the teeth, consisting of bacteria, mucus, and food debris. It is a major cause of tooth decay. Un-removed plaque mineralizes into a hard deposit called tartar that becomes trapped at the base of the tooth. Plaque and tartar irritate and inflame the gingiva. Bacteria, and the toxins bacteria produce, cause the gums to become infected, swollen, and tender.

 

Injury or trauma to the gums from any cause, including overly vigorous brushing or flossing of the teeth, can also cause gingivitis. The risks for developing gingivitis include uncontrolled diabetes, pregnancy (because of hormonal changes that increase the sensitivity of the gingiva), general illness, and poor dental hygiene.
