Healthy Ways to a Whiter Smile

Do you indulge in your one glass of antioxidant-packed red wine a night—and have the tooth stains to prove it? Food and drinks such as wine, coffee, cranberry juice, and mustard can dull even the brightest smiles. But before you reach for the drugstore whitening kit—which often is loaded with toxic ingredients that can weaken tooth enamel over time and make them even more susceptible to stains—look for these natural whiteners:
