3. Tomato Sauce
With its combination of high acidity and vibrant hue, tomato sauce is especially powerful when it comes to weakening tooth enamel and darkening its hue, all in one fell swoop. Try butter and parmesan on your next bowl of pasta instead and reap the benefits of dairy foods’ enamel strengthening powers.
4. Soy Sauce
You might want to try swishing your California roll in some spicy mayo instead of soy sauce next time to keep the bright white in your smile. Super dark soy sauce stains teeth just like it would a white tablecloth.
