The Anatomy of a “Perfect” Smile

Woman Hold a CameraYou’ve probably noticed that a friendly greeting (along with a bright smile) usually gets a smile in response! It’s a good feeling we humans are lucky to share. But, what exactly composes a fine smile?

What Makes Teeth Beautiful?

The Smile Line

There are dimensions to the ideal smile that dentists work to achieve. In youthful smiles, the curve of the upper lip follows the curve of the lower lip. When the biting edges of the lower teeth conform to the lower lip, it’s even more appealing.

Tooth Shape

Straight, uncrowded teeth make smiles come easier. Rough edges, chips, or anything asymmetrical is distracting. It is also typical for men’s teeth to be larger and more square, while women’s teeth (especially the incisors) tend to be smaller, more delicate, and more rounded.


Everyone knows white teeth look good, but teeth can also be too white and appear unnatural, almost startling. Strong healthy teeth reflect the light through layers of dentin and enamel, and appear as more translucent ivory than truly “white”.

If you have problems with your smile—could it be better?—let us show you what might bring a little more perfection. With a variety of conservative cosmetic dentistry options (such as bonding, veneers, crowns, or teeth whitening), we can make it happen!

About the Author:

Born in Allentown Pennsylvania, into a family of musicians, Rob Pearce grew up studying violin, percussion, jazz arranging and composition. After two years at the Berklee College of Music in Boston, he transfer to the pre-dental program at the University of Miami and later moved to San Francisco where he earned his Doctorate in Dentistry (DDS) from the University of the Pacific Arthur A. Dugoni School of Dentistry in 1990. For the past twenty eight years he has focused his efforts on mastering the art of high quality, long lasting “metal free dentistry,” a concept that was relatively new at the time but over the years has gained powerful momentum. In 2014 Dr. Pearce became a member of the “Visiting Faculty” of Spear Education, arguably the most prestigious dental continuing education program in the world. As a Spear Open Wide Foundation Ambassador, Dr. Pearce and his team travel to Guatemala to provide metal free dentistry to those who would otherwise receive no dental treatment at all. Dr. Pearce and Annette Rig were honored, and lucky enough to treat the very first patient at the Foundation’s first clinic in 2012. Since then, with the outpouring of support from our member dentists and American equipment manufacturers, we now have six clinics and have treated over 200,000 patients in need! The foundation’s goals include helping improve the education of Guatemala dentists. In 2015, as a member of the Education Development Committee, Dr. Pearce presented an all day lecture and workshop for the faculty and students at the Galvez School of Dentistry in Guatemala City.
