When you smile at another person, a warm, genuine smile, you tell that other person that he or she is attractive, pleasant, likeable, safe and secure in your estimation. A single smile is so powerful that it can often transform a person with low self-esteem, jolting them from negativity to a person with a positive attitude. An attractive smile is a wonderful asset which will contribute to improved self-esteem and self-confidence.
An ideal smile shows more teeth without excessive gum or lips covering the majority of teeth.
Teeth should sit perfectly upright in the mouth, not tipping inward or jutting outward.
Full smiles show more teeth and less dark space in the corners of the mouth. This could enhance the entire face.
Teeth should evenly fill the entire area of the smile, but not overwhelm the face.
In a great smile, all of the teeth fit together for a perfect bite.
