Acute Necrotizing Ulcerative Gingivitis (ANUG)

Ulcerative_necrotizing_gingivitisAcute 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.
Symptoms of ANUG include:

Painful gums
Profuse gum bleeding in response to any pressure or irritation
Gums appear reddened and swollen
Grayish film on the gums
Crater-like ulcers between the teeth
Bad breath
Foul taste

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.
Risks include the following:

Poor oral hygiene
Poor nutrition
Throat, tooth or mouth infections
Smoking
Emotional stress
