Amelogenesis imperfecta causes poorly shaped enamel. Tooth with this situation are usually smaller and discolored. After they erupt, these tooth will decay and erode shortly. These genetic mutations ship messages to the tooth to provide 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 inside layers of the tooth. This situation could also be related to osteogenesis imperfecta, a genetic situation that causes bones to type improperly. Dentinogenesis imperfecta leaves the tooth discolored, translucent, or opalescent. Tooth are weak and may put on shortly, break, and be misplaced simply.
