Final answer:
An overbite is the condition where the lower incisors are located behind the upper incisors, affecting the person's bite and potentially requiring orthodontic treatment to correct.
Step-by-step explanation:
If the lower incisors are in front of the upper incisors, the condition is called an overbite. The eight incisors, which consist of four at the top and four at the bottom of the mouth, are blade-like teeth used for biting into food. A proper alignment of these teeth is important for efficient biting and cutting. An overbite is a type of malocclusion where the upper teeth lie too far forward over the lower teeth. It is contrasted by an underbite, where the lower teeth are further forward than the upper teeth.
Conditions like overbite can affect a person's bite, ability to chew properly, and even the appearance of their smile. Treatment may include the use of braces or other orthodontic methods to bring the teeth into proper alignment.
