Cheddar cheese is one of Mother Nature’s most effective cavity fighters. After you indulge in a sweet snack, have a bite or two of cheese, right away. Sweet foods raise the acid levels in your mouth, dissolving tooth enamel and causing cavities. The cheese will stimulate your mouth to produce saliva, which neutralizes the acids in the sugar and protects your teeth from the cavity-producing attack. The calcium in the cheese may also give you the added bonus of strengthening your tooth enamel. Cheese has always been a nutritious, tasty snack – now it’s good for your smile, too.
