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.
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.
