WHAT IS GUM DISEASE?Gum disease symptoms include swelling, soreness or infection of the tissue supporting your teeth. Gingivitis and periodontal disease, a common cause of tooth loss in adults, are the two main forms of gum disease. Meaning inflammation of the gum, gingivitis appears as very red and swollen gums around your teeth, perhaps with some bleeding when you brush. Untreated gingivitis may lead to periodontal disease which affects the supporting teeth. When left to worsen, the disease will loosen the teeth as the anchoring bone is lost. If untreated you may even suffer tooth loss.
