Acute necrotizing ulcerative gingivitis (ANUG), also known as Vincent’s angina or trench mouth, is a type of bacterial infection that affects the gums and surrounding tissue in the mouth. ANUG is a relatively uncommon condition that typically occurs in individuals who have poor oral hygiene, compromised immune systems, or high levels of stress.
The primary cause of ANUG is an overgrowth of bacteria in the mouth, specifically a combination of anaerobic bacteria, spirochetes, and fusiform bacteria. These bacteria can quickly multiply and create an infection that leads to inflammation, ulceration, and destruction of the gums and other tissues in the mouth.
Symptoms of ANUG include painful and bleeding gums, bad breath, a metallic taste in the mouth, and ulceration of the gums and surrounding tissue. In severe cases, ANUG can also cause fever, malaise, and difficulty swallowing.
Treatment for ANUG typically involves a combination of antibiotics and good oral hygiene practices, such as regular brushing and flossing. Pain management medications and antiseptic mouthwashes may also be prescribed to help manage symptoms. In severe cases, surgery may be required to remove damaged tissue or promote healing.
If left untreated, ANUG can lead to serious complications such as systemic infection and even death, especially in individuals with weakened immune systems. Therefore, it is important to seek medical attention if you experience symptoms of ANUG.
