Definition Return to top

Amelogenesis imperfecta is when a person's teeth are covered with thin, malformed enamel.

Causes Return to top

Amelogenesis imperfecta is an inherited condition that is transmitted as a dominant trait. It causes the enamel of the tooth to be soft and thin. Because the dentin is visible through the thin enamel, the teeth appear yellow and are easily damaged. Both baby teeth and permanent teeth are affected.

Symptoms Return to top

Yellowish to dark-appearing teeth with thin enamel.
Easily abraded enamel
Abnormal tooth color

Exams and Tests Return to top

A dentist can identify and diagnose the condition.

Treatment Return to top

The treatment depends on the severity of the problem. Full crowns will improve the appearance of the teeth and protect them from damage.

Outlook (Prognosis) Return to top

Treatment is often successful in protecting the teeth.

Possible Complications Return to top

The enamel is easily fractured and damaged, which affects the appearance of the teeth, especially if left untreated.

When to Contact a Medical Professional Return to top

Call your dentist if you have symptoms of this condition.
