tooth extraction and drink sharing

Question: 

hello. please, i accidentally drunk from a glass of my friend, on the same day as i had tooth extraction (three stitches and still bit bleeding). it was not like from hand to hand, it was "sitting" on a table for a while, but very short - seconds to minutes, i just made a mistake and took hers instead of mine. I think hiv would die in water and if it is on the glass, then it would be only tiny amount and also would be incactive, but as there is real wound in my mouth, i would like to hear your opinion. I would not bother, but actually we did talk about our dental problems at that time - and about bleeding gums (i suppose gums usually bleed only when being washed by toothbrush, but... I am afraid.

Answer: 

Hi there, and thanks a lot for contacting the AIDS Vancouver Helpline for you HIV/AIDS related health information.

It sounds like you are concerned about your risk of HIV transmission.

The situation that you have described is a No Risk situation. Here are some of the reasons why:

  • HIV is a Human-to-Human virus. It cannot be transmitted to you by an object (a glass) or food/drink.

  • HIV needs a human host to survive. Once HIV is outside of the body and exposed to oxygen it can no longer transmit. Any bodily fluids that were in the drink or on the glass were outside of the body,exposed to oxygen and could no longer transmit HIV.

  • Saliva has an enzyme that inhibits the transmission of HIV.

I would encourage you to check out the following resources about HIV:

Thank you for contacting the AIDS Vancouver Helpline.
