Overbite is a condition in which the upper front teeth overlap the lower front teeth. Overbite is not necessarily a bad thing; most people have some degree of overbite. It?s when the overbite is too little or too large that problems may arise. An excessive or large overbite, also called a deep bite, can cause unhealthy teeth wearing, aesthetic concerns, and in some instances even jaw pain.
Overbite is often described as a percentage ? the percentage of your lower front teeth that are covered by your upper front teeth ? and an ideal overbite ranges from 5-25%.
