The teeth-staining potential of items like coffee, wine, and dark berries is easy to understand. These products contain plant compounds and intense natural colors that stick to the teeth and leave yellow residue behind, dimming the brightness of your smile. But dentists also want to warn their patients of other, less-obvious food sources that can stain the teeth.

What Foods Discolor Teeth?

1. Tomatoes

Tomatoes contain an abundance of acids that attack tooth enamel, causing this protective outermost layer to weaken and wear away. When enamel erodes, it exposes the layer of dentin underneath—and dentin is yellow. Any tomato-based foods pose a potential risk to the whiteness of your teeth. In addition to whole ones, be mindful of tomato juice, marinara sauces, ketchup, and tomato-based soups and stews like chili and gazpacho.

2. Balsamic Vinegar

Balsamic vinegar has a trifecta of staining capabilities. It is naturally very dark in color, it is incredibly sticky and adheres easily to the surface of the teeth, and it is highly acidic like tomatoes are. If you enjoy balsamic vinegar, dentists suggest using it as a salad dressing. Lettuce contains mineral compounds that form a protective film over the teeth, essentially safeguarding them—and their brightness—from the effects of the vinegar.

3. Clear Sodas

Pop is full of sugar that interacts with bacteria in the mouth, encouraging acid production. This leads to decay—and staining. But it's not just colas, root beer, and citrusy drinks you need to worry about. Clear or lighter-colored sodas like flavored seltzers, ginger ale, and lemon-lime varieties are equally high in sugar content. Instead, choose an unflavored or unsweetened carbonated water beverage. Even better, opt for water with plenty of ice and a slice of lemon.
