Prognathism

Extended chin

It is appropriate to see a dentist or orthodontist to treat abnormal alignment of the jaw and teeth. However, also contact your primary health care provider to rule out medical disorders that can be associated with prognathism.

• There is difficulty talking, biting, or chewing related to the abnormal jaw alignment.
• You have concerns about jaw alignment

The health care provider will perform physical examination and ask questions regarding the patient's medical history. Questions may include:

• Is there any family history of an unusual jaw shape?
• Is there difficulty talking, biting, or chewing?
• What other symptoms are also present?

Diagnostic tests may include:

• Skull x-ray
• Dental x-rays
• Imprints of the bite (a plaster mold is made of the teeth)
