Dental anatomy

The construction of the tooth is very simple at first glance, and consists of several layers. The first layer consists of a very hard material, the enamel. The second layer of yellowish dentine surrounds the pulp with the nerve. The tooth root finally is surrounded by cement, which anchors the tooth in the bone.

The root canal is located in the root of every tooth. Nerves and blood vessels run from here through the root tip into the tooth and out again. Starting from the root tip, the nerve impulse begins its journey through the body and transmits information, such as cold or hot to the brain.

We should not conceive of the inside of the root canal as a tube with smooth walls. The canal is rough and penetrated with billions of other microscopically small tubes. These tubules run through the entire dentine and have a honeycomb structure. You can see it - but only with an electron microscope. A fantastic insight into the structure of tooth enamel, the outer layer of the tooth, is shown in the following video. With increasing magnification, it can be seen that the tooth enamel is composed of tiny crystals.
