A deep overbite is a malocclusion that is recognized by an excessive degree of overlap of the upper and lower teeth. Although some overbites are hereditary, others are caused by a malformed jaw. Jaws grow unevenly under the pressure of certain habits when a child is young, resulting in an underdeveloped lower jaw or an overdeveloped upper jaw. Habits formed during early childhood, for example – such as thumb-sucking, prolonged bottle-feeding or tongue-thrusting – can cause this overbite. And habits developed later in life, such as eraserhead-chewing or nail-biting, can form an overbite as well.
HOW IS OVERBITE DIAGNOSED?
Diagnosis can be done by a dentist who would physically examine the upper layer of the teeth and do a teeth X-ray if needed.
HOW IS OVERBITE TREATED?
Treatment for overbite usually involves braces. Doing so helps in shaping the upper teeth layer and prevents them from protruding too much in the front. Usually the earlier the treatment begins, the quicker are the results because jaw bones are softer then.
DID YOU KNOW?
Normal overbite is between 3–5 mm (and approximately 20–30% of the height of the mandibular incisors) and is commonly expressed as a percentage.
