Ever wonder what makes a smile truly beautiful? Believe it or not, dentists have researched this information, using real-life people’s opinions, and studied it at length to ensure that their patients have the perfect smile walking out of their offices. Whether it’s the symmetry, the whiteness of the teeth, or the way the lips curve, many factors contribute to a stunning smile. Let’s explore the 11 scientifically researched elements that come together to create a captivating smile.
A Note Before Starting
Remember, what makes a smile beautiful can vary from person to person. For example in Japan, the “double tooth” or yaeba is considered attractive. Some people opt for cosmetic procedures to create this look, emphasizing the beauty in imperfect shapes.
That being said this article is based on various Western studies that have compiled the opinions of thousands of study participants. Using this information 12 qualities were chosen as the most influential in making a “beautiful smile”.
Beauty truly is in the eye of the beholder, so embrace your unique smile and consult with your dentist to achieve the look that makes you feel confident and happy.
Aesthetical Appearance of Healthy Teeth
The first qualities of a proper smile are the teeth themselves and their relationship to other teeth in the jaw.
Tooth Anatomy
The basic shape and features of each tooth contribute to the uniqueness of your smile. Teeth should have well-defined shapes with appropriate contours that match the natural curvature of the mouth. Variations in tooth structure can add undesirable character to your smile.
For example, in the picture above, this person’s smile has what is known as a black triangle (a gap in teeth) due to their tooth anatomy. This is generally considered an undesirable trait. To learn the exact shape of each tooth please follow the links below:
Length/Width Tooth Dimensions
The relative dimensions of teeth, including their width and length, play a critical role in the overall aesthetics of the smile. There is actually a golden proportion, often used to determine the most pleasing dimensions for each tooth in relation to the others. This is most important for your front teeth, known as incisors, which should have a length: width ratio of 75-80% (the width of the tooth should be 75-80% of the length).
Tooth Proportion
Tooth proportion refers to the size of one tooth in relation to another tooth. Funnily enough, this number has been found to be mathematically related to the Fibonacci sequence which dentists call the “golden sequence”. For example, using these numbers dentists have determined that the width of your upper central incisor should x1.618 the width of your upper lateral incisor.
Properly Aligned Tooth Axis
The tooth axis is the alignment of the teeth in relation to each other and the overall facial structure. Properly aligned teeth create a more balanced and symmetrical smile. In general, dentists look for teeth that have roots that are distally inclined. This means that the midline of the teeth angle slightly outwards closer to the jaw. Orthodontic treatments can help correct misaligned teeth, contributing to a more attractive smile.
Interdental Contact
Interdental contact refers to the points where teeth touch each other. Well-defined interdental contacts help to create a uniform and seamless appearance. Each tooth has its own esthetically pleasing spot for interdental contact. In general, the further back you go along your smile (from incisors all the way to molars) the closer to the gums the interdental contact should be. Proper contact points also prevent food particles from getting trapped between the teeth, promoting better oral hygiene.
Proper Interdental Closure (No Spaces Between Teeth)
Proper interdental closure ensures that there are no gaps between the teeth when you close them together, which is essential for both function and aesthetics. The way your teeth come together when you close your mouth (occlusion) and the movement of your teeth over time can affect the appearance of your smile. A well-aligned bite contributes to a harmonious and attractive smile.
Surface Texture
The surface texture of teeth affects their appearance and the way they reflect light. A natural texture with slight irregularities can enhance the beauty of your smile. Smooth and polished surfaces are desirable, but overly flat or uniform textures can appear unnatural.
Color
Tooth color is a crucial aspect of a beautiful smile. There are three fundamental elements of color to consider: hue (the basic color), chroma (the intensity or saturation of the color), and value (the relative lightness or brightness). Achieving the right balance of these elements, along with translucency and natural variations, results in a radiant and attractive smile.
Aesthetic Appearance of Healthy Gums
Gums also play a huge role in the appearance of a beautiful smile. This includes their color, shape, hand how much of it is showing when you smile.
Gingival Health
Gingival health, also known as gum health, is the foundation of a beautiful smile. Healthy gums are firm, pink, and fit snugly around the teeth. They play a crucial role in supporting the teeth and providing a pleasing frame for your smile. Regular dental check-ups and good oral hygiene practices (such as properly brushing and flossing) are essential for maintaining gingival health.
Zenith of the Gingival Contour
The zenith of the gingival contour refers to the highest point of the gum line around each tooth. It is indicated by the (+) in the picture above. Ideally, the zenith of the central incisors and canines is slightly higher than that of the lateral incisors. This subtle variation creates a natural and pleasing appearance.
Balance of the Gingival Levels
Balanced gingival levels ensure that the gum line is even and harmonious. Any asymmetry in the gum line can distract from the overall appearance of the smile. Correcting uneven gum levels can significantly enhance the aesthetics of your smile.
Lip Lines
Lip lines refer to the amount of tooth structure and gums you show when you smile. Usually, when you smile, 2-3mm of gum should be showing. Any more than this is considered a “gummy smile.” Any less than this, and you aren’t really smiling.
Conclusion
Creating a beautiful smile involves more than just straight teeth. It requires attention to gingival health, interdental closure, tooth alignment, and the intricate details of tooth form and color. By understanding and addressing these elements, you can achieve a smile that is not only aesthetically pleasing but also healthy and functional. Whether through regular dental care or cosmetic enhancements, investing in your smile can lead to improved confidence and overall well-being.
