Humans are the only animals that show their teeth in friendship

Some of the animals you posted have their mouths open as a way to cool off.
Others have their teeth showing just because they have their mouths open.
Having said the above, humans smile because they are in a pleasant mood.
Having said the above, I concede to your point
Still, a human smile is unique in my view and your post did not change my point of view.
Again, I will add, your contribution was great and faster than flash himself., it does carry on the topic.

I've known dogs that smile, or at least seemingly do. I'm not sure that it was a sign of friendship though, it could simply be that they learned this was a good way to get fed.

I wonder about dolphins. Is this a sign of friendship?

The real proof are the primates, though. They're doing what humans do, basically.

In real life, I have a reputation as a genuine Doctor Doolittle. I've amazed people with how well I can glean information from an animal, especially cats. Once, I visited a friend and her cat essentially told me that another cat, a younger one, had been in the house.

One thing I notice myself not doing is smiling with teeth. I smile, but not with teeth. When I'm with an animal it just doesn't occur to me that I ought to, and I don't.

I've learned the behaviour of slow-blinking to show being at ease or convey that there is no danger. Similarly, the dogs that smile may very well have learnt to do it from humans. I've seen this phenomenon as well, dogs showing their teeth in affection.

Cats can be hard to read, even emotionally.

Shouldn't matter with dogs; they study people constantly, in order to better predict us and most of them surely realize that a human smile is a good thing for them.

In cats and dogs, it signals trust, and possibly affection. It's pretty much the facial equivalent of turning on one's back.
