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).
