Teeth

Anatomical Overview

Teeth are hard organs in the mouth which fulfill functions of food capture and degradation, protection, and social functions (sound generation). Humans usually have 20 primary (deciduous, “baby” or “milk”) teeth and 32 permanent (adult) teeth. Teeth are classified as incisors, canines, premolars and molars. Incisors are primarily used for biting pieces from foods, while molars are used primarily for grinding foods after they are already in bite size pieces inside the mouth.
The anatomic crown of a tooth is the area covered in enamel above the cementoenamel junction (CEJ) or “neck” of the tooth. Most of the crown is composed of dentin with the pulp chamber inside. The crown is within bone before eruption. After eruption, it is almost always visible. The anatomic root is found below the CEJ and is covered with cementum. As with the crown, dentin composes most of the root, which normally have pulp canals. A tooth may have multiple roots or just one root (single-rooted teeth). Canines and most premolars, except for maxillary first premolars, usually have one root. Maxillary first premolars and mandibular molars usually have two roots. Maxillary molars usually have three roots.

The teeth are fastened to the jaw bones by the periodontium, which covers the roots and matches the periosteum of bones.
Dental nerve and blood vessels enter the pulp canal through the roots. The jawbones and CEJ are covered by gingiva.

In META-Health, conflicts affecting dental tissues concern biting, according to the function of the respective tissue and tooth: incisors are used to grab and cut off, canines to catch and hold fast, and premolars and molars to crush and grind. Stress trigger can be both physical and associated.
