A smile is one of the most beautiful expressions of human beings, capable of conveying joy, friendship and self-confidence. However, a perfect smile is not only determined by emotional expression, but also closely related to oral aesthetics. In teeth whitening and orthodontics, an important concept is often heard: smile curves. So, what exactly is a smile curve? Why is it so important?
Smile curves, also known as laugh linesIt is one of the important indicators to evaluate the aesthetics of a smile. It refers to the line of the incision of the upper anterior teeth, i.e. the position and contour of the upper anterior teeth when laughing. The ideal smile curve should be parallel to the upper edge of the lower lip and naturally curve downwards so that the smile looks natural and beautiful.
However, not everyone has a perfect smile curve. From an oral aesthetic point of view, smile curves are divided into three types: low smile curves, median smile curves, and high smile curves.
A low smile curve is defined as when the upper front teeth are less than 75% visible when you smile. In this case, the smile appears more restrained, lacks tension and vitality, and tends to give people a feeling of not being bright enough.
The median smile curve is defined as 75%-100% of the upper front teeth when smiling, with less than 2 mm of gum exposure when smiling. This smile curve is the ideal state to look natural and stretched, giving a feeling of confidence and pleasure.
A high smile curve is when you smile, when you smile, your upper front teeth are all exposed and your gums are more than 2 mm exposed. This smile curve is often referred to as a "gummy smile" and in some cases may give an overly exaggerated or unnatural impression that affects the overall smile aesthetic.
So, how do you adjust your smile curve? First of all, the position of the midline of the tooth is very important. The midline of the face should be aligned with the midline of the teeth so that the position and shape of the teeth look natural and symmetrical when smiling. Secondly, the amount of gum exposure is also one of the key factors. When smiling, the lips and teeth should be exposed between the top and bottom two millimeters of the gum margin to ensure that the smile does not look too exposed or underfilled. In addition, the width of the cheek corridor also affects the aesthetics of the smile. A moderate width of the cheek corridor can make a smile look fuller and more attractive.
Smile curve is one of the important criteria for evaluating the aesthetics of a smile, which reflects the overall aesthetic state of the teeth and mouth. Adjusting the curve of your smile is an important part of teeth whitening and orthodontics** to help you have a more natural, confident and attractive smile.
Therefore, understanding the concept of smile curves and how to adjust them is essential for people who are striving for the perfect smile. Smile
