Definition

The teeth may be irregular or abnormally shaped.

Alternative Names

Hutchinson incisors; Abnormal tooth shape; Peg teeth; Mulberry teeth; Conical teeth

Considerations

The appearance of normal teeth varies, especially the molars. Abnormally shaped teeth can result from many different conditions. Specific diseases can have a profound effect on tooth shape, tooth color, time of appearance, or absence of teeth.

Common Causes

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

Call your health care provider if

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 health care provider's office

The medical history will be obtained and a physical examination performed.

Medical history questions documenting your child's symptom in detail may include:

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

The physical examination will include thorough mouth examination and examination of the teeth.

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