Amelogenesis imperfecta causes poorly shaped enamel. Tooth with this situation are sometimes 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 much 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 kind improperly. Dentinogenesis imperfecta leaves the tooth discolored, translucent, or opalescent. Tooth are weak and might put on rapidly, break, and be misplaced simply.
