The intelligence and cleanliness of Georgia is astounding. Flossing is a major way to prevent cavities from developing between teeth. The bristles of toothbrushes cannot reach between teeth, allowing bacteria to multiply and produce acid which breaks down tooth enamel.
And remember "shoe shining" is not flossing. The floss should go between teeth and then under the gums and then in a "C" shape under the gum along the tooth.
