Broken Jaw

Broken Jaw Overview

A broken jaw (or mandibular fracture) is a common facial injury. Only the nose is broken more frequently. A broken jaw is the tenth most common fractured bone in the human body. Fractures (these are breaks in the bone) are generally the result of a direct force or trauma to the jawbone.
