AI; Congenital enamel hypoplasia
Amelogenesis imperfecta is a tooth development disorder. It causes the tooth enamel to be thin and abnormally formed. Enamel is the outer layer of the coronal, or crown portion of the teeth.
Amelogenesis imperfecta is passed down through families as a dominant trait. That means you only need to get the abnormal gene from one parent in order to get the disease.
The enamel of the tooth is soft and thin. The teeth appear yellow and are easily damaged. Both baby teeth and permanent teeth can be affected.
Exams and Tests
A dentist can identify and diagnose this condition.
The treatment depends on how severe the problem is. Full crowns may be necessary to improve the appearance of the teeth and protect them from further damage. Eating a diet that is low in sugar and practicing very good oral hygiene can reduce the chance of developing cavities.
Treatment is often successful in protecting the teeth.
The enamel is easily damaged, which affects the appearance of the teeth, especially if left untreated.
