What is a CAVITY?
Cavities occur as a result of tooth decay. Tooth decay is the destruction of the tooth structure. Tooth decay can affect both the enamel (the outer coating of the tooth) and the dentin (the inner layer of the tooth).
Tooth decay occurs when foods containing carbohydrates (sugars and starches) such as breads, cereals, milk, soda, fruits, cakes, or candy are left on the teeth. Bacteria that live in the mouth digest these foods, turning them into acids. The bacteria, acid, food debris, and saliva combine to form plaque, which clings to the teeth. The acids in plaque dissolve the enamel surface of the teeth, creating holes in the teeth called cavities, or caries.
What is a White Filling?
Silver fillings are composed of a mixture of metals that include mercury, silver, copper, and tin. For many years, it has been the standard choice o fillings for molar teeth. With the advent of modern technology white composites have now reached comparable strength, offering the advantage of a beautiful white smile without those unsightly metal fillings!
