It is not uncommon for one’s upper teeth to stick out in front of their lower teeth. In technical terms this is referred to as a Class II malocclusion, the prevalence of which is approximately 20-25% of the population. For whatever reason, this type of bite is referred to by the general public as an “overbite” which is not technically correct. The correct term is “overjet” — and the way that we explain it is that the upper teeth “jet” out in front of the lower teeth.
Overbite is an unrelated problem and you can read more about the differences on our common orthodontic issues page. It is possible to have an overjet and overbite simultaneously, or one without the other. Regardless, both are less than ideal and require orthodontic treatment to fix. Aside from the appearance, having an overjet can lead to jaw-joint issues and wear of the back teeth!
