Malocclusions are the abnormal alignment of the upper and lower teeth. This may result in teeth that look protruded, crowded, or unevenly spaced. Alternatively, some people with malocclusions may appear to have straight teeth, but the upper and lower teeth do not fit together properly. Teeth that are abnormally aligned are harder to clean, and therefore may experience higher instances of tooth decay, gum disease, or tooth loss. Malocclusions also may interfere with proper jaw development leading to problems with chewing and speaking. Orthodontic treatment is the best remedy for malocclusions and can create a beautiful and healthy smile through braces, aligners or oral surgery.
