what leads to gum infections
Food can get trapped in this space and cause a gum infection or gingivitis. Plaque is a thin film of bacteria. It constantly forms on the surface of your teeth. As plaque advances, it hardens and becomes tartar. You can develop an infection when plaque extends below the gum line.
Gingivitis is an inflammation of the gums, usually caused by a bacterial infection. If left untreated, it can become a more serious infection known as periodontitis. Gingivitis and periodontitis are major causes of tooth loss in adults, according to the American Dental Association.
