Absolutely not. There is no risk whatsoever in using a glass, a cup, a plate, a spoon or any other everyday household object that a person living with HIV has used.
For HIV to be transmitted, the virus has to be present in a body fluid which then enters another person's bloodstream. However HIV is not present in infectious quantities in saliva. Just as there is no risk in kissing a person with HIV, there is no risk in using an object that has had contact with their saliva.
While we're on the subject of ways you can't get HIV, it's also impossible to acquire the infection from a toilet seat, from a swimming pool, through mosquito bites, by donating blood, or through contact with saliva, tears, sweat, feces or urine.
