how to fix a subhuman smile

[jjm4765]

i have a pretty subhuman smile, the problem isn't say my teeth are yellow or stuff like that but i just look creepy when i smile.
the only example i can think of this really is sean o pry, in some photos when he smiles he just looks weird for some reason, i have the same problem
how can i fix this?

smile with your eyes

say ''hey'' in yourself (like you see someone you like/love) and hold that face so you smile natural
