A child’s development and orthodontic treatment can actually correlate with each other. A common condition that can be treated during a child’s growth is protrusion of the upper teeth ahead of the lower front teeth. The condition generally occurs because the lower jaw is shorter than the upper jaw. During the child’s development, while the upper and lower jaws are still growing, orthodontic appliances can be utilized to help the lower jaw catch up with the upper jaw. Also, other conditions, such as a severe jaw length discrepancy, can be treated effectively while a child is still maturing. If left untreated until a period of slow or no jaw growth, corrective surgery may be required to correct the discrepancy. Children who might have problems with jaw length or width should be examined no later than age 10 for girls and age 12 for boys.
