What is Overbite?

What exactly is an Overbite?




Overbite is when the upper front teeth overlap the lower front teeth vertically, causing the upper front teeth to extend further outwards than the lower front teeth. An overbite is a normal characteristic of the bite. The upper teeth are supposed to overlap and sit in front of the lower teeth. The upper teeth are also supposed to overlap the lower front teeth by 10-25%.


How is Overbite Different than a Deep Bite?


If the lower front teeth are sitting too far behind the upper front teeth, they will not bit with the upper teeth. In this case, the lower front teeth may grow taller and bite “deep” into the palate. Hence the term deep bite. Deep bites, can cause problems such as difficulty biting or chewing, speech difficulties, and can even lead to dental issues such as tooth decay or gum disease. Overbites can be caused by a variety of factors such as genetics, thumb-sucking, improper swallowing, or mouth breathing. Treatment for  deep bites depends on the severity and cause of the condition, and may include orthodontic braces, surgery and dental expander appliances.
