Whenever this topic is discussed, invariably smiling will be compared to teeth-baring.. This is nonsense. You can smile without baring your teeth, and bare your teeth without smiling. The majority of animals don't actually lift mouth corners when they're snarling their clenched teeth at you... and any smile that really shows all your teeth is an overindulgent fake one.

Which is the point. Just because you can smile without showing your teeth, doesn't mean showing your teeth while smiling makes it not-a-smile. Upturned corners + teeth showing falls under the general idea. Baring your teeth is showing your teeth and even though one doesn't normally have upturned corners while baring, one can bare their teeth with upturned corners and have it count as a smile. Hopefully that made some sense, I suck at explaining things...
