What are the two teeth under the two front teeth?

Some people are called lower incisors under the incisors near the midline, and academically they are called mandibular central incisors. At the same time, there is a tooth opposite the front teeth, which is the tooth next to the mandibular central incisor, called the mandibular lateral incisor.

The incisors mainly refer to the two teeth in the middle of the maxilla, which are called maxillary central incisors, and the two teeth next to the incisors are called maxillary lateral incisors. From the middle to both sides, they are called incisors, fangs, premolars and molars. Each tooth has its own different shape. The front teeth mainly have cutting function, similar to shovel shape. Fangs are usually also called tiger teeth, followed by premolars and molars.

Extended data:

Organizational structure:

Enamel: the surface layer of the crown, translucent, milky calcified tissue, containing 96% inorganic matter, 4% water and organic matter. ?

Dentin: It is the main part of teeth, light yellow and shiny, containing 70% inorganic matter and 30% organic matter. There are nerve endings in dentin, which are pain receptors.

Cementum: a layer of calcified connective tissue on the surface of root, yellowish in color, containing 55% inorganic substances, similar in composition and hardness to bone but without Haval canal. Cementum has a new function.

Dental pulp: the loose connective tissue in the pulp cavity, which contains blood vessels, lymphatic vessels, nerves, fibroblasts and odontoblasts, has the ability to form secondary dentin. The pulp nerve has no myelin sheath and no localization ability. Blood vessels enter and exit from the narrow apical foramen, which is easy to cause circulatory disorder and pulp necrosis.
