Underbite

An underbite is a term for a dental condition characterized by lower teeth that extend outward farther than the upper front teeth. This condition is also called a Class III malocclusion or prognathism. It creates a bulldog-like appearance in the mouth and face. Some cases of underbite can be severe, causing the lower teeth to extend far forward. Other cases are milder and nearly unnoticeable. An underbite is more than just a cosmetic issue. While some people may learn to live with mild cases, severe cases may cause oral health problems, such as: difficulty biting and chewing food, challenges with speaking, mouth and face pain due to misalignment of the jaw.
