If you already have some staining from coffee and other foods, just head to your supermarket's produce aisle and grab a pint of organic strawberries. It may seem counterintuitive due to their bright red color, but the berries are a proven tooth whitener, according to the Padjadjaran Journal of Dentistry. "The key thing is that strawberries contain malic acid, which whitens the teeth," Richard Marques, a celebrity dentist, tells The Guardian.
An apple a day may also keep the dentist away. That's because they, too, contain malic acid, as well as have a high water content, which helps wash away any stain-causing residue from your teeth, says Marques. And according to GQ, apples also stimulate saliva production, which helps prevent discoloration.
Finally, be sure to brush with a toothpaste that contains baking soda. They are significantly more effective at preventing stains and whitening teeth, according to a study in the Journal of Clinical Dentistry.
With this science and expert-backed advice, your smile will be ready to shine, even if you continue to enjoy your morning coffee.
