Malocclusion refers to teeth that are crooked, crowded, spaced, or protruding. It is a term used to describe teeth that do not fit together properly. Malocclusion is often genetic. It includes crowding, excess space between teeth, extra or missing teeth, and cleft palate. Malocclusions that are not genetic, but acquired can be caused by thumb or finger sucking, tongue thrusts, dental disease, and premature loss of primary or permanent teeth.
If malocclusion is left untreated then it may worsen over time. Crooked or crowded teeth are more difficult to clean and maintain. This could lead to cavities, gum disease, and potential tooth loss.
There are three classes of malocclusion:
- Class 1 is the most common. The bite may seem normal, but the upper teeth slightly overlap the lower teeth.
- Class 2 is an overbite. This happens when the upper jaw and teeth severely overlap the bottom jaw and teeth.
- Class 3 is an under bite. An under bite occurs when the lower jaw protrudes forward and causes the lower jaw and teeth to overlap the upper jaw and teeth.
Malocclusion is the most common reason to visit an orthodontist. The objective is to fix the positioning of the teeth. To do this your orthodontist will use braces or other appliances.
