It is treated with chlorhexidine and metronidazole

Explanation

Acute necrotizing ulcerative gingivitis (ANUG), also known as trench mouth, is an acute infectious intraoral disease characterized by red, ulcerated gingiva, halitosis, friable mucosa and punched out interdental papillae. Fever, malaise, and lymphadenopathy are often present.1

The term “trench mouth” was coined during World War I when the disorder was seen in trench-bound young soldiers.2 It is most common in young males, and is associated with malnutrition, smoking, stress, immunosuppression, and poor personal hygiene. The infection is generally polymicrobial.3,4

Treatment includes local mouth care with hydrogen peroxide or chlorhexidine oral rinses. If systemic symptoms are present, oral antibiotics (metronidazole or penicillin) are indicated. Follow up with a dental clinic needs to be arranged to help reduce the likelihood of recurrence.4
