I know they sterilize beer mugs in bars but at home does the dish detergent
in hand washed glasses kill the bacteria from people's filthy mouths?

I don't think it kills anything. I think it washes away most of the
germs, all or almost all if you do a good job.

Heat would kill them. I doubt a dishwasher's hot water is hot enough to
kill t hem and I'm not sure if the dry cycle, which I never use, is hot
enough either. But dishwashers usually do a great job of washing so I
doubt there are any germs left by the time the dry cycle would start.

But I don't worry about it. I'll drink from someone else's canteen,
water bottle, glass. I wipe the place where I put my mouth, but only so
they will think I'm civilized. Everytime I get sick and then get well
again, I figure I'm teaching my body how to make a different kind of
antibody.
