What is the anatomy of teeth?
Your teeth are composed of four dental tissues. Three of them—enamel, dentin and cementum—are hard tissues. The fourth tissue—pulp, or the center of the tooth that contains nerves, blood vessels and connective tissue—is a soft, or non-calcified, tissue.
How is the anatomy of a tooth related to its physiology?
Teeth sit in the jaw bone but do not directly touch the bone. They are embedded in what amounts to a shock absorber called the periodontal ligament. This system is designed to withstand and exert forces in a vertical vector (chewing), which they can do effectively with hundreds of pounds or kilograms of vertical force.
How many parts are in the teeth?
A tooth is divided into two basic parts: the crown, which is the visible, white part of the tooth, and the root, which you can’t see. The root extends below the gum line and helps anchor the tooth into the bone. Your teeth contain four kinds of tissue, and each does a different job.

- Incisors. The incisors are the eight teeth that are most visible in the front of the mouth.
- Canines. Moving outward in the mouth, the next teeth are the canines.
- Premolars. Continuing outward, the premolars, or bicuspids, serve the purpose of chewing and grinding up food.
- Molars.
- Third Molars.
Which tooth has shortest root?

What is the structure of the oral cavity?
BASIC ORAL ANATOMY Oral Cavity (mouth) The entire oral cavity is lined with mucous membrane tissue. The oral cavity consists of the following two areas: The vestibule is the space between the teeth and the inner mucosal lining of the lips and checks. The oral cavity proper is the space contained within the upper and lower dental arches.
