Malocclusion of teeth

Alternative names:

crossbite; crowded teeth; misaligned teeth; overbite

Symptoms:

• abnormal alignment of teeth
• abnormal appearance of the face
• difficulty or discomfort when biting or chewing
• speech difficulties (rare)

Signs and tests:

Most malocclusion is discovered by the dentist on routine examination. Occlusion is checked by pulling the cheek outward and having the person bite down normally. The dentist usually refers the person to an orthodontist for diagnosis and treatment.

Dental X-rays, head/skull X-rays, or facial X-rays may be required. Impressions (plaster or plastic molds of the teeth) are often needed.
