what causes gingivitis
Types of Gum Disease. Untreated gingivitis can advance to periodontitis and can eventually lead to tooth loss and other health problems. Gingivitis is the mildest form of periodontal disease. It causes the gums to become red, swollen, and bleed easily. There is usually little or no discomfort at this stage. Gingivitis is often caused by inadequate oral hygiene. Gingivitis is reversible with professional treatment and good oral home care.
