Acute Necrotizing Ulcerative Gingivitis (ANUG), which is also known as trench mouth or Vincent's Stomatitis, is a painful bacterial infection and ulceration of the gums. The term "trench mouth" comes from World War I, when the disorder was common among soldiers. The mouth normally contains a balance of different microorganisms. ANUG occurs when there is an overabundance of normal mouth bacteria resulting in infection of the gums, which develop painful ulcers. Viruses may be involved in allowing the bacteria to overgrow.
Treating ANUG typically requires antibiotics and dental treatment. Irrigation of the mouth with salt water or peroxide solution often helps to relieve symptoms. Rest, a balanced diet, no smoking, and avoiding hot and spicy foods are also important.
