When the upper jaw is behind the lower jaw, the condition is termed as underbite. It is a form of malocclusion. Underbite is also termed as “Bad Bite”. In medical terms, underbite is referred as “Mandibular Prognathism”.

What Causes Underbite?

It is usually a birth defect. It is nothing but a misalignment of the lower jaw corresponding to the upper jaw. It is reported that in some ethnic groups this condition is more prevalent than the general population. The chances of people with conditions called gigantism are affected with Underbite condition are very high.

Underbite can also be caused due to thumb sucking and thrusting the tongue outside against the teeth in early childhood.
