Most orthodontic problems are inherited. Examples of these genetic patterns are crowding, spacing, protrusion, extra or missing teeth and some jaw growth problems.
Other malocclusions (bad bite) are acquired. In other words, they develop over time. They can be caused by finger or thumb sucking, mouth breathing, dental disease, abnormal swallowing, poor dental hygiene, the early or late loss of baby (primary) teeth, loss of permanent teeth, accidents, poor nutrition, or some medical problems. Whatever the cause, we are usually able to treat most conditions successfully.
