Can Sucking cause of AIDS?

Yes.

*Any* exchange of bodily fluids *can* cause HIV.

Semen and blood are more likely to transmit HIV.

Gum disease is an opening for blood exchange.

If you get semen in your bad gums, or blood from bad gums in a very small tooth scratch, you have just have blood exposure to bodily fluids.

Depends on what your question really is?
no
If there is a transfer of infected bodily fluids, yes.

To "Heather Dawn", below: if there is an open sore in the mouth transmission of the virus IS possible and it HAS happened.
Aids is not transmitted through kissing or the mouth. So as long as whoever doesn't have sores in their mouth and the guy doesn't let off in the person's eye (becuase your eyes lead directly to your blood). Be careful, other STDs can be passed through the mouth, etc.
Do you mean if someone sucks someone elses pe**s who is infected with AIDs will they get AIDs also??

If that is your question then the answers is yes! AIDs get passed on through any bodily fluid, whether thats semen, saliva or blood!
ANY interchange of bodily fluids can cause HIV. . .which eventually leads to AIDS. the virus doesn't live long outside the body, but it's easily transmitted through blood, semen and saliva. If you want to have oral sex with an HIV positive person (or someone who's status you don't know), you will want to use a dental dam (or a clean unused unlubricated condom).
