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

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.
