Understanding Acute Necrotizing Ulcerative Gingivitis

Acute necrotizing ulcerative gingivitis (ANUG) is an inflammation of the gums characterized by the presence of necrotic ulcers covered by tissue debris in which gums are painful to the touch and bleed readily. The onset of ANUG can be very rapid, but seems to be connected to pre-existing gum inflammation and bleeding known as gingivitis.

Poor hygiene that allows plaque buildup is the primary preventable cause of ANUG, but additional factors such as smoking and compromised immune system function caused by other chronic or acute disease. Patients with ANUG typically demonstrate a reduced ability to cope with psychological and emotional stress.

The traditional therapy for ANUG has been gum surgery. However, the alternative approach of periodic scaling, root planing, and antimicrobial rinses with 0.12% chlorhexidine has been shown to be effective in halting and even reversing the disease. As with most diseases of the teeth and gums, prevention is best obtained by practicing a program of rigorous oral hygiene that includes brushing and flowing after every meal and twice-yearly visits to your dentist.
