If the normal bacteria in the mouth overgrow, the gums can become infected.
The gums hurt, and people sometimes have extremely bad breath.
A professional cleaning, sometimes followed by hydrogen peroxide rinses and antibiotics, plus good oral hygiene are effective.
Acute necrotizing ulcerative gingivitis is now rare, but minor gum infections involving just a few teeth probably occur relatively commonly. The severe form usually affects only people with an impaired immune system (for example, due to human immunodeficiency virus [HIV]/acquired immunodeficiency syndrome [AIDS] Human Immunodeficiency Virus (HIV) Infection Human immunodeficiency virus (HIV) infection is a viral infection that progressively destroys certain white blood cells and can cause acquired immunodeficiency syndrome (AIDS).

Did You Know...
The infection is caused by an abnormal overgrowth of the bacteria that normally exist harmlessly in the mouth. Poor oral hygiene usually contributes to the development of ANUG, as do physical or emotional stress, poor diet, and lack of sleep. The infection occurs most often in people who have gingivitis Gingivitis Gingivitis is a mild form of periodontal disease characterized by inflammation of the gums (gingivae).

Acute necrotizing ulcerative gingivitis is far more common among smokers than nonsmokers.
Symptoms of ANUG
Usually, ANUG begins abruptly with painful and bleeding gums, excessive saliva production, and sometimes extremely foul-smelling breath. People may also have a fever and feel ill. The tips of the gums between the teeth appear punched-out and become sores (ulcers) covered with a gray layer of dead tissue. The gums bleed easily, and talking, eating, and swallowing cause pain. Often, the lymph nodes under the jaw swell, and a mild fever develops.
Diagnosis of ANUG
A dentist's evaluation
When the breath smells extremely foul, dentists sometimes suspect the diagnosis of acute necrotizing ulcerative gingivitis (ANUG) immediately, as soon as they come into contact with affected people. Other times the diagnosis is evident from the appearance of the mouth and gums.
If the gums do not respond quickly to therapy, dentists may do other tests to rule out other causes.
Treatment of ANUG
Good oral hygiene
Treatment of acute necrotizing ulcerative gingivitis (ANUG) begins with a gentle, thorough, professional cleaning done over several days.
At home, people are instructed to rinse with salt water, a hydrogen peroxide solution (ordinary drugstore hydrogen peroxide mixed half-and-half with water), or chlorhexidine (an antiseptic). Rinsing may be recommended instead of brushing for the first few days because of the sensitivity of the gums. People can use a soft toothbrush or washcloth to wipe the teeth.
If the cleaning must be delayed (for example, if a dentist or the proper tools are not available), doctors give antibiotics by mouth (such as amoxicillin, erythromycin, or tetracycline).
The infection responds very well to good oral hygiene (daily brushing and flossing). Dentists also recommend people rest, drink plenty of fluids, eat nutritious foods, and take drugs for pain. Dentists also recommend people avoid smoking or eating hot or spicy foods.
