The foods you eat have a profound impact on your dental health. A nutrient dense diet helps maintain and rebuild your teeth, as well as the gums that support them. Avoiding corrosive foods high in sugars and acids will help prevent dental erosion and cavity formation. Junk foods such as candy, cookies, and soda may be much more readily recognized as sources of sugar, but refined carbohydrates such as bread, crackers, and pasta also contain enough sugar to adhere to teeth and provide acid-forming bacteria and create long-term dental erosion and cavities. Dietary acids found in sodas and coffee can also directly erode tooth enamel. This means that you should even avoid consuming large quantities of healthy but acidic foods such as citrus fruits, yogurt, and wine if you wish to minimize cavity formation. Consistent attention to your diet will help prolong the beauty and strength of your teeth.
