Does a normal set of teeth have slight overbite?

Yes, a normal set of teeth typically has a slight overbite. Overbite refers to the vertical overlap of the upper teeth over the lower teeth when the jaws are closed. A slight overbite, where the upper incisors (front teeth) overlap the lower incisors by a few millimeters, is considered normal and is known as an overjet. This slight overlap helps in proper function and aesthetics. However, an excessive overbite or deep bite, where the upper teeth significantly overlap the lower teeth, is considered a dental malocclusion and may require treatment.
