The integrity of the teeth and the degree of whiteness are related to the overall aesthetic and health of the teeth. White spots on the surface of the teeth are often due to some defect in the development of the enamel or insufficient calcification. Enamel hypoplasia: This is usually caused by the loss of minerals from the enamel on the tooth surface; without a good lifestyle habit in daily life, it can easily lead to the erosion and loss of calcium and phosphorus on the teeth, so the teeth will change and show white shifts. Common causes of enamel hypoplasia include high fluoride content in local drinking water sources, apical infection of milk teeth in childhood affecting the enamel development of permanent teeth below, and family genetics. When white spots appear on teeth, it is recommended to pay attention to them. White spots indicate insufficient mineralization of enamel or some degree of decalcification, and decalcification is the main cause of tooth decay, and decalcified teeth are vulnerable to acid erosion and bacterial invasion. Patients with white spots on teeth should pay attention to oral cleaning, use correct brushing method to remove plaque thoroughly and prevent caries. If you have aesthetic needs, you can consult your dentist for teeth whitening or aesthetic porcelain veneer treatment.
