Gum disease, also known as periodontal disease, is a bacterial infection of the gums and tissues that support your teeth. Gingivitis affects only the gums. It is a mild form of gum disease, and if properly treated, may be reversed. Without prompt gingivitis treatment, it can turn into periodontitis. The best way to avoid or manage gum disease is by practicing good oral hygiene and visiting your dentist regularly. Gum Disease Treatment in Brooklyn
