This depends on which elements of a smile you are refering to. The act of raising the corners of your mouth is done by three muscles, primarily the zygomaticus major and risorius muscles and aided by the buccinator muscle. If you squint your eyes while you smile you may also use orbicularis oculi. If you scrunch your nose with your smile then you may also use your procerus and nasalis muscle. If your forehead wrinkles and eyebrows raise then your occipitofrontalis helps as well. For someone with a very expressive smile, they are likely using alot of their facial muscles (up to 15, the rest would oppose a smile and cause frowning).

Why do you smile?
* You smile because the body has a sense of happiness, which activates your nerves and pulls your mouth into the most relaxing state possible: the smile! * You smile when you are happy or trying to prove you are happy to people around you. Smiling is actually important, believe it or not. It shows you respect what someone is saying, doing, etc. It is easiest to smile, believe it or not. At first, frowns seem easier. I mean, no one actually naturally smiles in their sleep... if you see what I mean.... Also it is a action you do that performs on your face, like if you happy.... a frown will come on your face if you are sad or grumpy.
Is a gummy smile a dominant trait?

What mucsles are used to smile?
The main muscle that pull the edges of the lips superoposteriorly to form the smile is the buccinator. _________________________________ Actually, the buccinator is more useful for holding the cheek to the teeth during chewing, (and is also quite useful for trumpet playing). Although the buccinator does aid a little in smiling, it is primarily the zygomaticus major and risorius muscles that are responsible for a smile :)
