When meeting someone, the most prominent feature is your smile. According to a recent survey cited by USA Today, 47% of people notice the smile on first impression, while only 31% notice the eyes.

For centuries, artists and architects have recognized the importance of symmetry and proportion in concepts of beauty, and have implemented them into all aspects of their work. Yet, perhaps the most stunning displays of such artistry are evident in the human body. For example, the relationship between the length of your nose, the position of your eyes, and the length of your chin is an important variable in the mathematical equation of beauty. But how your smile matches the rest of the face is just as important, which raises the question—what makes a smile beautiful?

“Every person has a unique smile that fits their facial structure,” says Dr. Ryan Blissett, a Harvard-trained prosthodontist. “The secret is in knowing how to create a smile that best complements the rest of their facial features.”

There are basic guidelines to which prosthodontists adhere. For example, the “Golden Proportion,” also known as the “Magic Ratio,” is based on a very specific formula derived from mathematics and nature. In dentistry, the “Golden Propor- tion” is a method used to determine the ideal size and shape relationships for teeth. But the end result is as subjective as it is mathematical. An eye for facial esthetics that goes above and beyond what is taught in dental school is the craft of great cosmetic dentists.

Prosthodontic dental specialists have extensive training in esthetic and recon- structive dentistry and are considered true cosmetic dentists. They take the pro- portions of the face, age, ethnicity, and even personality into consideration in the restoration of their patient’s teeth and self-confidence.

For example, canted eyes are beautifully paired with teeth that are also oriented along an angle; teeth that are completely straight across would look out of place. Age is also a factor. “Lengthening” teeth, which is accomplished by removing gum tissue, can make teeth look thinner and younger. Ethnicity influences the shape and size of teeth as well. Your facial midline, existing teeth, and shape of your lips also play a role in smile design.

A lot goes into the design of your smile, so if you are interested in crafting the perfect smile for you, then visit a prosthodontist today or ask your dentist about how a smile makeover could benefit you.
