The term malocclusion refers to misalignment of teeth. You may have been born with malocclusion, so your teeth simply grew in crooked, or the misalignment and crowding of your teeth occurred over a period of time. Either way, not only can malocclusion pose cosmetic issues, but it can have a negative effect on your speaking and eating abilities as well.
Types of Malocclusion
Malocclusion encompasses multiple types and classifications of misalignment issues, including twisting or rotation of the teeth and molars that do not meet when you bite down. In some cases, the top front teeth are pushed outward in an upper protrusion.
In other cases, a misplaced midline results when the front top teeth don’t meet with the front bottom teeth. Transposition occurs when teeth protrude through the gums in a position where another tooth is supposed to be.
Practically any type of crowding or spacing issues, rotation or twisting of the teeth, or bite problem – including overbite, underbite, open bite, or crossbite – is included under the umbrella of malocclusion.
There are three classifications of bite or misalignment problem.
- Class 1 malocclusion: While the bite may be normal, the upper teeth overlap the lower teeth slightly. This is the most common type.
- Class 2 malocclusion: Known as overbite or retrognathism, class 2 involves a severe overlap of the upper teeth and jaw over the bottom teeth and jaw.
- Class 3 malocclusion: Known as underbite or prognathism, class 3 occurs when the lower teeth and jaw overlap the upper teeth and jaw. Thus, the lower jaw juts forward.
Causes of Malocclusion
The most common cause of malocclusion is genetics. However, there may be other causes, including the development of abnormally-shaped teeth, lost teeth, or impacted teeth; thumb sucking or overuse of a pacifier as a small child; having fillings or crowns that do not fit correctly; a serious injury that causes misalignment of the jaw; or developing a tumor of the mouth or jaw.
Orthodontic treatment at Timothy Foley DDS, M.CI.D, FRCD(C) with Dr. Timothy Foley is the main treatment available for malocclusion, which includes getting braces, Invisalign, or other corrective treatments. Treatment is ideal not just to have your smile improved, but because it makes the teeth easier to clean and maintain, lowers the risk of gum disease and tooth decay, and can even take pressure off the jaw and teeth.
Think about orthodontic treatment if you (or your child) display any signs of malocclusion. Early treatment of malocclusion during childhood can lessen expensive treatment later on.
