Malocclusion

When the upper part of the jaw and the lower part of the jaw are not the same size, bite problems can occur. When the lower jaw is smaller than the upper jaw, it is called an overbite. When the reverse is true, it is called an underbite. Another related alignment disorder is called a crossbite. Crossbites occur when lower teeth are in the wrong position. They may be incorrectly positioned sideways, forward or backward.
