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

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