When the upper front teeth stick out too far forward, or the lower teeth don�t extend enough this is called protrusion. Because of the abnormal contact between the upper and lower front teeth it could cause injury to the lower teeth. It also causes poor bites and may even be from uneven jaw growth. This problem can be caused by thumb and finger sucking.
