The food we eat affects our oral health, and our oral health also directly affects our nutritional health. Teeth, gums and the oral cavity need adequate hygiene to remain healthy. Selecting a diet which optimizes oral health is important. Several foods have been shown to promote tooth decay and are called cariogenic. These include:
* sugar,
* candy,
* desserts and pastries,
* sugared beverages such as beer, soda and fruit juices, and
* dried fruit, and honey.

The more frequently you eat sugar or sugary foods, the more likely you will experience tooth decay and root cavities. Some foods have been shown to be protective against oral cavities, including cheese and other dairy products. The protein, caseinates, in dairy products appear to bind to the outer tooth and prevent bacteria from sticking to the tooth surface. The calcium in the dairy products may also protect the teeth.

A third group of foods are the low or noncariogenic foods such as meats, vegetables, fresh fruits, cooked cereals, breads and pasta.

So how can you guarantee a healthy smile? Eat right. Variety is important to getting all the nutrients you need for healthy teeth. Watch out for sugar and high sugar foods and beverages. If you do consume foods high in sugar try not to do so frequently and always give your teeth a good cleaning afterwards. Choose healthy snacks such as:
* fresh fruit,
* raw vegetables,
* popcorn,
* whole grain cereal with low-fat milk, and
* cheese.

Try not to snack just before bed, since saliva flow is low while we sleep. If you don't take good care of your teeth, sore gums or even tooth loss may affect your ability to eat a healthy diet.

Take care of your teeth and see your dentist regularly.
