Dairy products play an important role in good oral health. June, which is Dairy Month, is a good time to be reminded of the strong link between the two.

Dairy products are a main source of calcium. The average person's diet, however, lacks sufficient calcium which is essential to dental health at all stages of life.

Cheese, one of the best sources of calcium, is also one of the safest snack foods from a dental standpoint. Certain cheeses, such as aged Cheddar, Swiss and Monterey Jack, can be helpful in reducing decay, according to research.

Aged cheddar cheese aids the remineralization of tooth surfaces and arrests the early development of cavaties. A study at the University of Iowa found that eating processed cheese can help rebuild tooth surfaces that have started to decay from the acids produced by the bacteria in plaque. Cheese eaten with a meal can help counter the effects of these acids.

Calcium is important for pregnant woman. A baby's teeth begin to develop between the third and sixth months of pregnancy. The developing baby's need for 400 milligrams of calcium per day is supplied by the mother's diet. If calcium in her diet is inadequate, the mineral will be depleted from her bones.

Calcium is also important during childhood when it fortifies oral health by helping build strong jaw bones, decay-resistant teeth and healthy gums. Scientific studies have linked low calcium intake over a long period of time with thinning of the jawbone.

Dairy foods also contain protein, magnesium, phosphorous, and a number of vitamins, all important to dental and general health. People who don't have special weight or cholesteral problems may choose to consume wholemilk products in moderation. For calorie counters and those on low-cholesterol diets, nonfat and lowfat diary products are excellent choices.
