Though it may be possible to get AIDS from saliva, it is not actually the saliva that would carry the virus but the blood that might be in the mouth. Saliva is a very strong substance, to kill germs in our mouth (we get more germs in our mouth than anywhere else on our body)and will kill the HIV very quickly.

What might be in our mouth though is blood - from brushing teeth or flossing or braces. If that blood gets into a cut in another person's body or is shared on a fresh tooth brush immediately after brushing, there is the possibility that if the person has HIV, it could be passed in the blood.

Saliva is too strong for the AIDS virus which is actually very fragile, so you don't have to worry about a thing.

Thanks for asking and feel free to ask other questions.
