Is there such a thing as a “perfect” smile?


Some people grin across their entire face, some people just barely tug the corners of their mouth. There is no such thing as a “perfect” smile, although – if a new study is anything to go by – that’s not 100 percent true. There are certainly certain characteristics that appear “more beautiful” to us and a “beautiful” smile very well has an influence on our fellow men. These new findings may also help plastic and reconstructive surgery.

American researchers published new study results

Now it’s proven – there is no such thing as a perfect smile. However, the researchers of the University of Minnesota also found that smiling may very well have a decisive influence on other people can have. Nathaniel Helwig, together with his team, has published a study in the scientific journal “Plos One” published a study that traced the mystery. The results show that the Position of the corners of the mouth, the Extent of the teeth shown and also the Smile width are crucial. The researchers are also certain that facial expression is the fundamental aspect of social interactions and nonverbal communication.

These findings may also be important for doctors when operating on people who can no longer smile properly due to an accident or serious illness, or who are unhappy with their smile due to a congenital deformity. Plastic and cosmetic surgery offers numerous options for making the face look more “beautify”. In the process, attention should always be paid to a natural result be respected.

The perfect smile depends on three characteristics.

Smiling protects against danger, for example, by correctly interpreting a face that is currently angry. We smile several times a day and often do not even know how important our smile is for the interpersonal relationships is. People who cannot smile properly are sometimes prone to depression.

To prove that smiling has a enormous has an enormous influence, the study tested 800 subjects who had to rate 3D animations of smiling people. The subjects had to indicate whether the smile was “seemed genuine”, “be pleasant” or sometimes “disturbing” or even “put on” appeared to be “forced. In the end, the researchers agreed that less is often more. A smile that went all over the face was perceived as less pleasant; a restrained smile was not automatically classified as unpleasant or wrong.

Three characteristics, according to the study results, were particularly important: The corners of the mouth, the visibility of the teeth and the width of the smile. It seems that in this sense there is indeed a formula for a “perfect smile”.

How did the subjects react?

A narrow smile is readily perceived as gloating or contemptuous; especially when many teeth are shown. A high smile, which also has no width, appears aggressive – especially if teeth are also revealed. However, if the smile is broader and higher, the teeth provide a reinforcement of the cordial and open impression.

A narrow or high smile, with no teeth showing, was also not considered a “perfect” perceived. A smile that is too narrow often appears frustrated or bored to those around us, while a smile that is too high appears mask-like. A half-high and half-wide smile, in which only a few teeth are shown, is said to be already “almost perfect”.

The study findings demonstrate that a “perfect” Smile actually “moderate” be. Whether with teeth or even without teeth – as long as the smile is not “extreme” looked, it was perceived as pleasant. An asymmetrical smile was also pleasant, according to the study results.

Particularly in the case of esthetic, surgical treatments in the oral region, such findings may possibly help patients, for example in the case of a Treatment with fillers for a lip shaping, to better advise and achieve natural, “perfect” results.
