“The best framework for teeth whitening is healthy gums and tooth surfaces. One of the essential items in our OnTheGo SmilePerformance kit includes ACT Anticavity Fluoride Mouthwash ($9), which is formulated without alcohol. The mint flavor is my favorite and the fluoride strengthens the tooth surface as well as acts as a chelating agent in targeting stained debris, bacteria, saliva components and other remnants. I also recommend brushing or flossing within 15 minutes after each meal. This practice will not only ensure fresh breath but also a destained surface from the meal. Sipping sparkling water in-between bites can also minimize stain deposits on the tooth surface, which increase with time unless removed.” —Chevy Chase, MD cosmetic dentist Claudia Cotca, DDS, MPH
