Yesterday I have shared cutlery and food with a HIV exposed person - this person is under medication and completed his dose only yesterday after he got exposed to a possible HIV infection. I just wanted to know that if I might also get infected because I shared food and saliva and cutlery with him. also the fact that I had swollen and inflammed gums inside my mouth - they are not bleeding gums but they definitely swollen from the overgrown gum that had been reduced (Crown lengthening) 2 months ago. Food was lodged inside and hence the swollen gum. The dentist dislodged the food particles to close the root canal. What are my chances of getting infected with HIV in this case?
