A type of malocclusion in which the lower jaw and front teeth jut out in front of the upper ones.
A form of malocculsion (irregular alignment) in which the lower teeth are positioned in front of the upper teeth when the jaw is closed. An underbite is usually due to a person’s heredity and may become a problem for cosmetic reasons. An underbite may also prevent opposing teeth from meeting properly when chewing, which can lead to the loosening of some teeth. An underbite is corrected with braces as recommended by an orthodontist, who is a specialist in bite problems.
A condition in which the lower incisors pass in front of the upper incisors when the mouth is closed.
