Tooth Anatomy

The structure of a tooth is similar to an apple

In a very simplified way, the general structure of a tooth is similar to that of an apple.

Like a peel, enamel covers and protects the visible part of the tooth.

Dentin is the second layer of the tooth. Like the flesh of the apple, this material takes up the largest volume of the tooth. Although its strength is lower than that of enamel, it remains as tough as a human bone. Dentin is the last “armor” protecting the life of the tooth because it offers protection to its central part. Once attacked by decay, the dentin deteriorates very quickly.

Dental pulp (the nerve of the tooth) is the equivalent of the heart of the apple. Located in the center of the tooth, the pulp is composed of tiny blood vessels and nerves, making the tooth sensitive to pain.
