When there is not enough space in the upper jaw for one’s teeth to grow in at a normal angle, the front teeth may be forced outward to make room for the rest. Teeth crowding can also contribute to the development of overjet. If performed too late in a child’s physical development, these behaviors can significantly impact the way the jaw forms and the angle at which the teeth erupt. However, it can also result from habits such as thumbsucking, tongue thrusting, or use of a pacifier. Overjet is often inherited, as genetics play a large role in the development of one’s teeth and jaw. If you’re unsure exactly what condition(s) you’re dealing with, it’s a good idea to get checked out by a dentist before shopping around for treatment options so you can go into this process fully informed! What Causes Overjet? If you have an overjet, it’s very possible that you have some degree of overbite (and/or some other type of misalignment, such as teeth crowding or spacing) as well.Īll that said, it can be difficult to define the exact nature and severity of a bite issue on your own. The reason for this confusion is sound: these conditions commonly exist alongside one another. Overjet is regularly confused with overbite, a malocclusion that causes the upper teeth to vertically overlap the lower teeth.
Although there is no unanimous agreement on exactly how much horizontal projection is cause for concern, 1-3 mm is generally considered to be within the range of a normal bite. Overjet is a type of malocclusion that occurs when the upper teeth erupt at a different angle than the lower teeth, growing outward rather than in parallel with the lower arch.
