Acute necrotizing ulcerative gingivitis (ANUG), also known as trench mouth, is a painful gum infection that causes inflammation, bleeding, and ulceration of the gums. It usually develops due to a bacterial imbalance in the mouth, often linked to poor oral hygiene practices such as irregular brushing and flossing.

Other factors like stress, smoking, malnutrition, and a weakened immune system can increase the risk of developing this condition. When harmful bacteria multiply rapidly, they can invade the gum tissues and lead to pain, swelling, and gum damage if not treated promptly.

What Are the Types of Acute Necrotizing Ulcerative Gingivitis?

Acute necrotizing ulcerative gingivitis can appear in different forms depending on the severity and recurrence of the infection. Identifying the type helps guide treatment and management.

The main types include:

Simple ANUG: Usually involves localized gum pain, bleeding, foul odor, and ulceration of the gum tissue.
Severe or complex ANUG: Involves more extensive tissue destruction, deeper ulcers, and may include symptoms such as fever and general discomfort.
Recurrent ANUG: Occurs when the condition develops repeatedly, often due to persistent risk factors like poor oral hygiene or weakened immunity.

What Are the Symptoms of Acute Necrotizing Ulcerative Gingivitis?

Acute necrotizing ulcerative gingivitis can cause several uncomfortable symptoms affecting the gums and surrounding tissues. These symptoms may appear suddenly and can worsen if treatment is delayed.
