The most basic definition of malocclusion is “the misalignment of the jaw.” This common disorder affects people of all ages. The Mayo Clinic estimates more than 200,000 cases are diagnosed every year in the United States alone.

Some of the most common complications associated with malocclusion are crowded teeth, cross bite, overbite, under bite and an open bite, according to Healthline. Symptoms caused by the misalignment of the jaw include frequent biting of the tongue or cheeks; discomfort or difficulty when chewing, biting, speaking or yawning; and the feeling that your teeth don’t line up correctly.
