Acute necrotizing ulcerative gingivitis ANUG is a common, non-contagious infection of the gums with sudden onset. The main features are painful, bleeding gums, and ulceration of inter-dental papillae the sections of gum between adjacent teeth. This disease, along with necrotizing ulcerative periodontitis NP or NUP is classified as a necrotizing periodontal disease , one of the seven general types of gum disease caused by inflammation of the gums periodontitis. The often severe gum pain that characterizes ANUG distinguishes it from the more common chronic periodontitis which is rarely painful. The causative organisms are mostly anaerobic bacteria , particularly Fusobacteria and spirochete species. Predisposing factors include poor oral hygiene, smoking, poor nutrition, psychological stress, and a weakened immune system.

Acute necrotizing ulcerative gingivitis is a painful infection of the gums. Symptoms are acute pain, bleeding, and foul breath. Diagnosis is based on clinical findings. Treatment is gentle debridement, improved oral hygiene, mouth rinses, supportive care, and, if debridement must be delayed, antibiotics. Acute necrotizing ulcerative gingivitis ANUG occurs most frequently in smokers and debilitated patients who are under stress. Some patients also have oral candidiasis. Ulcerations, which are pathognomonic, are present on the dental papillae and marginal gingiva.
