Hi,
Thanks for writing.
We do not see HIV passed through french kissing (or deep kissing). HIV is not passed through saliva.
HIV can be passed through blood, but when blood is in the mouth it becomes so diluted with the saliva that it would not be passed.
You are not at risk for HIV from deep kissing, even with canker sores.
Hope this helps. Please feel free to submit another question as needed.
