Q. Why is milk good for my teeth when it is high in sugar?
A. Milk is in fact good for your teeth, especially for children. The reason is that milk contains calcium which is needed for building stronger enamel (the outer layer of your tooth), and is low in acidity. In some studies it has been found that cheese and milk can not only protect your enamel from degradation caused by high acidic foods, but can also reverse that damage.
However, it is true, milk is high in simple sugars. A single serving of milk usually contains anywhere from 9 to 14 grams of sugar. That is why whenever it comes to your health, moderation is key. Drink too much milk and the high sugar can cause damage, especially if your oral hygiene habits are poor.
Adults should drink a little less milk, and instead, eat more cheese. Cheese, again in moderation (it does have a moderate amount of fat after all!), is one of the best foods for your oral health. It is High in calcium and Vitamin D, and low in acidity. During chewing, cheese can also be beneficial as food debris remaining on your teeth sticks to it pretty well.
