Cross bite

Occlusion. The upper molars are inclined or positioned inward more than the lower molars. Most often occlusion is caused by a narrow upper jaw or the incorrect position of the teeth within the dental arches. In many cases, a cross bite is associated with mouth breathing.

  

Facial profile.: The cross bite alone has no significant influence on the facial profile; however, it is frequently associated with an open bite which results in a long and convex facial profile.

Airway: The airway may be tapered and the patient may have snoring problems. Cross bite is diagnosed in children and adults who frequently keep their mouth open because of impaired nasal breathing.

Chewing function: The chewing function is satisfactory.

Jaw joints: A cross bite often causes uneven occlusion and may also cause clicking or popping in the joints.

 

Teeth wear. Molar wear may be noticeable.
