What is periodontal disease?
Periodontal disease, also known as gum disease, is a serious inflammatory disorder that, left untreated, can lead to tooth loss. The word periodontal literally means "around the tooth." Periodontal disease is a chronic inflammatory disease that affects the gums and bone supporting the teeth. Periodontal disease can affect one tooth or many teeth. It begins when the bacteria in plaque (the sticky, colorless film that constantly forms on your teeth) causes the gums to become inflamed.
