What Is Acute Gingivitis

Acute necrotizing ulcerative gingivitis (ANUG) is a rapidly destructive, non-communicable microbial disease of the gingiva in the context of an impaired host immune response. It is characterized by the sudden onset of inflammation, pain, and the presence of “punched-out” crater-like lesions of the papillary gingiva.
