Tender, bleeding gum for 6 days even by touching with tongue. what's the difference between symptoms of gingivitis and hiv that shows on gum ? thanks

Open sores: gingivitis is an inflammation of the gum tissue. If you have open sores, it is most likely not gingivitis. Advise dental visit asap

ANUG and HIV: is the acute necrotizing ulcerative gingivitis (ANUG), but with more intense bleeding and pain may be seen in necrotizing periodontitis in HIV/AIDS patient. Antimicrobial treatment is recommended. See oral pathologist for diagnosis and management.
