Tooth demineralization is a process by which the teeth lose important strengthening minerals. It is considered an early stage of tooth decay, and typically causes white spots to appear on the teeth. Demineralized areas can usually be remineralized if proper oral hygiene measures are followed, but they can lead to dental decay. This condition typically occurs due to the build-up of plaque on the surface of the teeth, often from poor dental hygiene. When teeth are not properly cared for, plaque, a sticky, opaque substance comprised mostly of bacteria, is allowed to build up on the teeth. The bacteria in plaque produce acids that can damage tooth enamel, leaching its minerals away. The white spots on the teeth tend to be chalky, white and rough or porous in texture. Because they are rough, more plaque tends to stick to demineralized areas, making the areas lose even more minerals. Remineralization can happen when better and more meticulous dental homecare is performed. The addition of prescription strength fluoride treatments to the areas will help to strengthen and smooth the affected areas and restore a better structural composition to the tooth. The white spotting will remain on the tooth even after remineralization has taken place.
