Amelogenesis imperfecta causes poorly shaped enamel. Tooth with this situation are usually smaller and discolored. After they erupt, these enamel will decay and erode shortly. These genetic mutations ship messages to the enamel to supply faulty enamel. The enamel of a affected person with dentinogenesis imperfecta could look just like amelogenesis imperfecta.

Dentinogenesis imperfecta is a genetic dysfunction of the event of the interior layers of the tooth. This situation could also be related to osteogenesis imperfecta, a genetic situation that causes bones to type improperly.
