Having dull or yellow teeth is not something new. Certainly, many people experience it time and again. Yellowing teeth can be a result of poor oral hygiene or the natural process of aging. Nevertheless, it is entirely possible to whiten that smile. Our dental spa in San Francisco, CA offers professional teeth whitening services. Smile whitening (sometimes called “bleaching”) is a simple, non-invasive dental treatment. It is used to whiten natural tooth enamel and is an ideal way to enhance the beauty of every smile. Our professional teeth whitening dentists have years of experience. They will take you through a simple teeth cleaning procedure.
