Acute necrotizing ulcerative gingivitis is caused by the abnormal growth of bacteria in mouth?

Necrotizing ulcerative gingivitis (NUG) is a severe gum infection that can lead to tissue damage and tooth loss. It is caused by an overgrowth of certain types of bacteria in the mouth, such as Fusobacterium necrophorum and Prevotella intermedia. These bacteria produce toxins that damage the gums and surrounding tissues.

NUG is most common in people with poor oral hygiene, malnutrition, or a weakened immune system. It can also be triggered by certain medications, such as birth control pills and steroids.

Symptoms of NUG include:

- Bleeding gums that are swollen and red

- Ulcers on the gums that are covered with a gray or yellow membrane

- Painful chewing and swallowing

- Fever and chills

- Fatigue

- Bad breath

If you have any of these symptoms, it is important to see a dentist immediately. NUG can be treated with antibiotics, pain relievers, and improved oral hygiene. In severe cases, hospitalization may be necessary.
