Gingivitis is a condition in which there is swelling of gums which surrounds the teeth. It is one of the common teeth problems in adults which affect the health of periodontal tissues. When gingivitis is left untreated, it can cause receding of gums which may damage the teeth permanently. The intensity of infection and inflammation may vary from mild gingivitis to severe form of periodontal infection. In severe cases, it may cause ulcerative gingivitis which is potentially dangerous to life.
