The Structure Of Our Teeth

A gap between the reality of tooth construction and how this is perceived can contribute to oral disease.

A Biological Addition

Our teeth are misunderstood. We tend to think of them as hard, inert elements of our anatomy but as the sectional diagram shows, they are complex, living structures.

The enamel is relatively tough but not so hard as to be brittle. This is mainly composed of crystalline calcium phosphate and protects the other layers of our teeth.

Just beneath is the dentine, made from organic material such as collagen and calcium, or phosphate crystals. Also dentinal fluid, which shields the pulp from microbial invasion.

The calcified cementum helps a tooth to stay in place, forming a bridge between the periodontal ligament and the dentine.

At the core of a tooth is the pulp, an insensitive name for a sensitive area. This contains nerves, blood vessels, tissues and specialist cells, which provide nutrients to keep your tooth alive.
