“Crossbite” is a malocclusion that occurs when the rows of teeth in the upper and lower dental arches essentially cross one another. It can be caused by inadequate jaw size, heredity, or mouth breathing (induced by large adenoids and tonsils), which results in an upper jaw that is too narrow to fit properly outside the bottom teeth. This narrowing of the upper jaw caused by mouth breathing results from the tongue dropping from its normal position at the roof of the mouth, where it would otherwise promote widening of the upper jaw. If left untreated, permanent adult teeth growing in the narrow upper jaw of a mouth-breathing child become squeezed inward and land inside the corresponding row of top teeth.
It’s difficult to maintain good oral hygiene with crooked and crowded teeth. Left untreated, these problems can lead to tooth decay, gum disease and even tooth loss. By addressing orthodontic problems early, some can be reduced in severity or even eliminated.
