In the early stages some affected people may complain of a feeling of tightness around the teeth. Three signs/symptoms must be present to diagnose this condition: * Severe gum pain. * Profuse gum bleeding that requires little or no provocation. * Interdental papillae are ulcerated with dead tissue. The papillary necrosis of NUG has been described as "punched out". Other signs and symptoms may be present, but not always. * Foul breath. * Bad taste (metallic taste). Malaise, fever and/or cervical lymph node enlargement are rare (unlike the typical features of herpetic stomatitis). Pain is fairly well localized to the affected areas. Systemic reactions may be more pronounced in children. Cancrum oris (noma) is a very rare complication, usually in debilitated children. Similar features but with more intense pain may be seen in<unk>  periodontitis in HIV/AIDS.
