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).

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 :)
