Which is unnatural when you think about it, showing teeth is interpreted by most animals as a sign of aggression.
I remember reading that if you smile at strange kids (or dogs), don't show your teeth, they'll get scared or agitated. Similarly, if you are e.g. greeting a small child, squat so that you are eye level with them - kids (and dogs) hate when somebody huge is hanging over them.
