Enamel hypoplasia is a common condition in which the structure of the teeth is abnormal. It generally refers to abnormalities in the structure of the enamel during the development of the teeth due to a number of factors. The main causes are severe nutritional disorders, systemic myopathies, endocrine disorders, and infections such as severe periapical infections of the milk teeth. Enamel hypoplasia is associated with tooth loss and color changes. It can have a significant impact on the aesthetics of the anterior region and on the posterior region, affecting the degree of occlusion of the posterior teeth. The most important treatment for enamel hypoplasia is aesthetic restoration. If there is no tooth loss you can do teeth whitening treatment, both laser whitening and cold light whitening will change the color of the teeth and make them more aesthetically pleasing. Dental veneers can be done if there is a small amount of defect, or porcelain crowns for restoration of teeth if there is a large area of defect. It is very important to prevent enamel hypoplasia. Since enamel hypoplasia is a defect left during the development, the inflammation of the periapical period of the milk teeth must be treated in time, and the decay of the milk teeth must be paid attention to, never think that the milk teeth will be replaced by the permanent teeth sooner or later, so do not pay attention to the diseases of the milk teeth, which is very wrong. The disease of milk teeth can affect the health of permanent teeth. If there is a lack of nutrition during pregnancy, it is necessary to supplement the nutrition in time, so that these dental development problems can be well prevented.
