Crossbite Before & After Treatment

Posterior crossbites usually result from a constricted upper jaw or an abnormally wide lower jaw. A narrow upper jaw will often force a patient to move their lower jaw to the side or forward when closing into a stable bite. When closed into this accommodated position, the lower teeth are located outside the upper teeth. An anterior crossbite is where the upper front teeth develop behind the lower front teeth. Both anterior and posterior crossbites in young children can usually be corrected with a simple expansion appliance. Once all of the permanent teeth have erupted, braces are usually needed to correct anterior and posterior crossbites.
