The dental formula for the adult human beings is 2123/2123. There are 2 incisors, 1 canine, 2 premolars aand 3 molars in one row..
What is human dental system?
The permanent dentition is composed of 32 teeth with 16 in each arch. There are eight teeth in each quadrant, composed of two incisors (central and lateral), a canine, two premolars, and three molars. These teeth are referred to as numbers, 1 (central incisor) to 8 (3rd molar or 'wisdom' tooth)..
What is the structure of the human teeth?
Structure of the Tooth A tooth consists of enamel, dentin, cementum and pulp tissue. The portion of a tooth exposed to the oral cavity is known as the dental crown, and the portion below the dental crown is known as the tooth root..

The dental formula is used to represent the arrangement of the teeth in upper and the lower row. The dental formula for the adult human beings is 2123/2123. There are 2 incisors, 1 canine, 2 premolars aand 3 molars in one row.
Humans usually have 20 primary (deciduous, "baby" or "milk") teeth and 32 permanent (adult) teeth. Teeth are classified as incisors, canines, premolars (also called bicuspids), and molars. Incisors are primarily used for cutting, canines are for tearing, and molars serve for grinding.
Overview
Human teeth function to mechanically break down items of food by cutting and crushing them in preparation for swallowing and digesting
Anatomy
Dental anatomy is a field of anatomy dedicated to the study of tooth structure. The development, appearance
Parts
Enamel is the hardest and most highly mineralized substance of the body. It has its origin from oral ectoderm
Development
Tooth development is the complex process by which teeth form from embryonic cells, grow, and erupt into the mouth
Supporting structures
The periodontium is the supporting structure of a tooth
A tooth consists of a crown and one or more roots. The crown is the functional part that is visible above the gum. The root is the unseen portion that supports and fastens the tooth in the jawbone. The root is attached to the tooth-bearing bone—the alveolar processes—of the jaws by a fibrous ligament called the periodontal ligament or membrane.
Each tooth consists of 3 anatomical parts: the crown, neck, and root. The crown: it is the visible portion of the tooth that protrudes from the gum. The crown is covered by enamel, the hardest substance in the human body. The neck: it is the area where the crown joins the root.
A tooth consists of two main structures:
Crown. This is the part of your tooth that you can see — the portion above your gums. Enamel — a hard, protective substance — covers your tooth crown.
Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function. The incisors cut the food, the canines tear the food and the molars and premolars crush the food. The roots of teeth are embedded in the maxilla (upper jaw) or the mandible (lower jaw) and are covered by gums.
The tooth is made up of a crown and either single or multiple roots. The anterior teeth in both the upper and the lower jaws, from the right first premolar to the left first premolar, are single rooted teeth. On the upper jaw, the maxillary second premolar may have two roots and all of the maxillary molars have two to three roots.

Medical condition
Abrasion is the non-carious, mechanical wear of tooth from interaction with objects other than tooth-tooth contact. It most commonly affects the premolars and canines, usually along the cervical margins. Based on clinical surveys, studies have shown that abrasion is the most common but not the sole aetiological factor for development of non-carious cervical lesions (NCCL) and is most frequently caused by incorrect toothbrushing technique.
