They may be bright red, but malic acid, a chief component of this summery fruit, acts as a natural astringent to remove surface tooth discoloration, says Dr. Irwin Smigel, president of the American Society for Dental Aesthetics. Fresh, juicy strawberries taste great in any meal—salads, desserts, cereal—and are widely available at farmers markets this time of year, so getting your daily dose is both simple and delicious.
The loud crunch you hear when you bite into this hard fruit may be annoying, but it’s also good for your choppers. Apples’ crispiness strengthens gums, and their high water content increases saliva production, dispersing and neutralizing colonies of bacteria that lead to bad breath and plaque, says Smigel.
Drink lots of water to keep your mouth hydrated and your smile bright, advises Smigel, who recommends sipping and swishing between glasses of wine and when eating dark, pigmented foods to prevent staining. However, while water reduces the acidity in your mouth and the resulting damage to your enamel, Dr. Smigel warns against imbibing too much sparkling water, which has greater potential to erode enamel and harm teeth.
