10 Causes of Mouth Ulcers
Cause #6: Acute Necrotizing Ulcerative Gingivitis
Acute necrotizing ulcerative gingivitis (ANUG) is a common infection with a sudden onset. Patients with ANUG often experience bleeding gums, pain, and ulceration of the gums between adjacent teeth. If left untreated, it can become a recurrent or chronic condition.
It is usually caused by anerobic bacteria such as the spirochete species or Fusobacteria. Risk factors of ANUG include smoking, poor oral hygiene, stress, malnutrition, and immunosuppression. Treatment includes antibiotics, improvement of oral hygiene, and debridement.
