Rostral crossbite occurs when one or more of the upper incisor teeth are located behind the lower jaw counterpart in a dog that has a mesaticephalic skull type. This condition commonly occurs secondary to retained deciduous incisors not allowing adult teeth to assume their correct position. The crowding and loss of the self-cleaning mechanism can result in periodontal disease, pain and/or tooth loss.
To treat rostral crossbite, either extract or move the affected teeth into a functional position.
