What is decalcification?
Decalcification, or the appearance of white spot lesions, occurs as a result of demineralization and can be a sign of oncoming carious lesions or early tooth decay. Demineralization is the process through which minerals such as phosphorus and calcium vanish from the tooth structure. Mineral dissipation is usually the result of acids formed by bacteria present in the mouth. The multiplication and adhesion process of bacteria begins within seconds of brushing, and plaque formation begins. The bacteria in plaque have the ability to replicate in an oxygenated environment. Without proper oral hygiene care, the bacterial plaque thickens and inhibits saliva penetration; thus causing the calcium and ions of the portion of the tooth in contact, to diffuse into the plaque forming tarter. As a result white spots begin to appear.
