Anatomy of the mouth. The mouth, consists of 2 regions, the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. The oral cavity is bounded at the sides and in front by the alveolar process (containing the teeth) and at the back by the isthmus of the fauces.
You have a variety of teeth in your mouth, all serving different functions. Each tooth, however, is comprised of the same tissues and fibers to keep it in place and working properly. Your teeth are held in place by your gums, the soft pink tissue you see around your teeth when you smile. The part of the tooth that you can see emerging from your gums is known as the crown.
