Malocclusion (poor bite) is usually caused by problems in the shape or size of the jaw or teeth. If children have a small jaw, their teeth may grow into a space that is too small. Under these crowded conditions, teeth will push each other out of proper position. Other causes include thumb-sucking, pacifier use, and tooth loss.
Malocclusion means having crooked teeth or a poor bite .. Bite refers to the way the upper and lower teeth line up. In a normal bite, the upper teeth sit slightly forward of the lower teeth. Very few people have a perfect bite. Most of the time, malocclusion is a cosmetic problem, which means that people don't like the way their teeth look.
