Underbite: What is It and How is It Treated?

Underbite, also known as a reduced overjet (confusing we know!), is a type of bite issue where the lower front teeth protrude beyond the upper front teeth. This can affect a person's appearance, speech, and chewing.​

How to Identify an Underbite

Underbite, in its extreme can prevent the lips from closing normally around the teeth and can be associated with a relatively strong lower jaw.
