Studies indicate that as people mature, their teeth may shift. This variable pattern of shifting occurs progressively, and is known as maturational change. Although shifting slows down after the early 20’s, most people continue to experience it to a certain degree throughout their life. Even children who experience no orthodontic problems during development may require orthodontic treatment as adults. Crowding of the lower front teeth is the most probable maturational change. Wearing retainers as instructed will stabilize the new teeth positions. Beyond the phase of full-time wear, wearing retainers at night can also prevent maturational movement.
