Most often crooked teeth, overbites, and underbites are inherited traits just as the color of your eyes or size of your hands. Other causes of misaligned bites are early loss of baby or adult teeth; improper fit of dental restorations (for example, fillings or crowns); gingivitis ; undue pressure on the teeth and gums; misalignment of the jaw after an injury; tumors of the mouth or jaw; or common oral health problems in children such as thumb sucking, tongue thrusting, pacifier use beyond the age of three, or prolonged use of a bottle.
