We're also the same way about showing our teeth. Smiling is so natural to us, but showing your teeth like that is generally seen as a sign of aggression for most animals.

Is at only among predators or herbivores too?

I can't think of any herbivores that bare their teeth. I can't think of any herbivores that fight much with their teeth, so baring them would have no reason to be seen as aggressive.

Pretty sure gorillas do

Not sure about gorillas but I don't think so actually... Mostly pounding isn't it

It's pretty similar with humans as well. When you smile you only show a tiny bit of teeth maybe sometimes a little more. But go up to a mirror, rise your upper lip to expose you teeth and you'll look vicious af.
