We have 135 distinct gestures and expressions of our face, head and body. A British research team has cataloged these and registered that 80 of them are head gestures. It takes 64 muscles to frown and only 13 muscles of face are used to smile.

During this type of smile, both the upper and lower incisors are exposed. It happens during a goal in football match or in any other games and sports. Generally no eye to eye contact takes place during this type of smile.
Oblong Smile
Oblong smiles are not a real smile and generally made as a part of courtesy or politeness. During this type of smiles the lips are drawn fully back from both the upper and lower teeth and thereby making the oblong with the lips. During formal moments, these types of smile are seen more as to give feelings that the joke was very nice.Tight Lipped
