The tooth: its anatomy and its environment
How is a tooth?
The tooth has two parts. The crown is the visible part of the tooth in the mouth. The root: a fabric minerals cover it, cement. It is located under the gums and is anchored in a cell by bone fibers or periodontal ligament. The collar is the boundary between the crown and root.
The various components of a tooth
If you cut a tooth in the direction of height can be distinguished from outside to inside:
At the crown
Enamel: covering the crown is a highly mineralized tissue (the hard tissue of the body).
Dentin: beneath the enamel layer is less mineralized and is the major part of the tooth. The so-called coronal pulp is the living part of the tooth. Located in the dentin, it consists of blood vessels and nerves that provide the input of nutrients needed to sustain life in the tooth but also of its sensitivity. It continues to the end of the tooth pulp by the so-called root.
At the root level
The cement is a layer of mineralized tissue that covers the entire root.
The flesh called root: in continuity with coronary pulp, it communicates with the rest of the body (blood vessels and nerves) with a vent on the tip of the root (the apical foramen).
