Acute necrotizing ulcerative gingivitis (ANUG) is a serious infection of the gums that causes ulcers, swelling, and dead tissues in the mouth.
ANUG most often impacts people who are 35 years of age and younger. Factors that may increase the risk of ANUG include excess bacteria in the mouth due to:
- Lack of dental care
- Poor dental hygiene
- Poor diet
- Vitamin deficiencies
- Infections in the throat, teeth, or mouth
- A weak immune system
Symptoms may include:
- Pain in the gums
- Gums that bleed easily
- Bad taste in the mouth; extremely bad breath
- Red and swollen gums
- Gray residue on the gums
- Large ulcers or loss of gum tissue in between teeth
- Swollen lymph nodes
You will be asked about your symptoms and medical history. A dental exam will be done.
Images may be taken of your teeth and face. This can be done with x-rays.
Although ANUG is a painful condition, it can be treated. Treatment may include:
- Antibacterial mouthwash
- Pain control with nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen
- Dental surgery
- Regular dental cleanings
- Antibiotics to treat infection
- Changes in diet
To help reduce your chances of ANUG:
- Take proper care of teeth and gums.
- See your dentist regularly.
- Eat a balanced diet.
