Dr. Nammy Patel, founder of Green Dentistry in San Francisco, and author of the bestselling book Age With Style— A Guide to a Youthful Smile and Healthy Living, discusses how she designs a smile.

I design a smile by looking at each individual person and their chief concern. What is it that they do not like about their teeth? Also, how can we make the smile natural and beautiful using the knowledge that I have with something called the golden proportion, which is an ideal of how our face and teeth and lips should fit together? I take all that information, I work with a laboratory technician if we’re doing something like a veneer, to make sure that we find the best size, shape, and color of the teeth that’s going to make you look really natural and radiant, and having a smile that you really enjoy for a lifetime.
