Orthodontics is a process of moving teeth through bone to new positions. The fibers attached to the teeth for support will try to return them toward their old positions before new fibers and bone are produced. Following active orthodontic treatment, retainers will be placed to maintain the new positions of the teeth. Once stabilization occurs, continued retainer wear is recommended. Like all parts of the body, teeth and bone are constantly changing and adapting. Only conscientious wear of the retainers will keep movement to a minimum.
