A smile is a facial expression that's made by turning up the corners of the mouth, usually exposing the teeth. It usually signifies pleasure or enjoyment. It's the first impression people have of you, and is practiced by those who are confident that their teeth will shine when they smile. If you're afraid to smile because your teeth aren't exactly white, then you need to get one of the many teeth whitening systems that's available on the market today. It'll restore your teeth's natural whiteness and have you smiling again in no time.

In physiology, a smile is a facial expression formed by flexing muscles most notably near both ends of the mouth, but also around the eyes. Among humans, it is customarily an expression of pleasure or amusement, but can also be an involuntary expression of anxiety, in which case it can be known as a grimace. There is much evidence that smiling is a normal reaction to certain stimuli and occurs regardless of culture.
