Causes

• Congenital syphilis
• Cerebral palsy
• Ectodermal dysplasia, anhidrotic
• Incontinentia pigmenti achromians
• Cleidocranial dysostosis
• Ehlers-Danlos syndrome
• Ellis-van Creveld syndrome

When to Contact a Medical Professional

If the shape of your child's teeth appears to be abnormal, consult a dentist or other health care provider.

What to Expect at Your Office Visit

The dentist will examine the mouth and teeth. You will be asked questions about your child's medical history and symptoms, such as:

• Does the child have any medical conditions that may cause abnormal tooth shape?
• At what age did the teeth appear?
• In what order did the teeth appear?
• Are there other tooth problems (color, spacing)?
• What other symptoms are also present?

Diagnostic tests that may be performed may include dental x-rays.
