When Upper Jaw Expansion Benefits Your Child
by Tracey Sandilands
Upper jaw expansion is a form of orthodontic treatment that is used in specific cases. By widening the circumference of the palate, the perimeter of the dental arch increases to create more space for teeth growth. Reasons for Treatment Palatal or maxillary expanders, according to Dr. Martin Fine, do three things that make expanding the upper jaw particularly helpful during childhood:
Corrects a crossbite. The upper teeth should close around the outside of the lower teeth. In a patient with a narrow palate, it can be the other way around, with the upper teeth biting inside the lower teeth. This results in asymmetrical growth of the lower jaw, which can cause facial asymmetry, if it isn't corrected in time.
