The upper jaw, or maxilla, forms the upper part of your mouth. It holds your upper teeth and contributes to the structure of your face. It's like the foundation for your pearly whites. Think of it as the top bunk in the mouth's bunk bed. It's essential for chewing, speaking, and even facial expression. It articulates with other bones in the skull, creating the mid-face structure. Any damage can affect your smile and speech.
