Hello. please help. I had wisdom tooth extraction and the same day in the evening my friend stopped by. I accidentally changed the glasses and drank from hers :( it was some 10 hrs after surgery the wound still bleeding a bit and i am not sure about her hiv status, has had several one night stands last year.... I am very scared. I know she has problems with bleeding gums when brushing teeth. Do you think i can be infected? It was not from mouth to mouth that glass sharing, maybe she drank few min before me maybe only seconds. Thank you very much. Iappreciate your time and help a lot.
