Enamel defects refer to abnormalities in the outer layer of teeth, known as enamel. These defects can manifest as discoloration, pitting, or irregular surface texture. They may result from various factors, including genetic conditions, nutritional deficiencies, or environmental influences during tooth development. Common types of enamel defects include hypoplasia, which is a reduction in enamel thickness, and hypomineralization, where the enamel is poorly mineralized. These conditions can increase the risk of tooth decay and sensitivity, making dental care essential for affected individuals. Regular check-ups with a dentist can help manage and treat these issues effectively.
