Tooth Iii (Tooth, Plural. Teeth)

Tooth III is one of the hard structures of the oral cavity, designed for grinding food. The root of each tooth is located in a separate dental alveolus of the alveolar arch of the lower or upper jaw. The roots of the teeth grow tightly together with the surface of the alveoli through the periodontal membrane. The outer part of the tooth (crown) is covered with enamel, and the part of the tooth located inside the alveolus - the root - is covered with special cement; The tooth consists mainly of dentin, which surrounds the tooth cavity on all sides, filled with pulp. The embryonic cells from which the tooth develops form the tooth germ. There are four different types of teeth: canine, incisor, molar, and molar. See also Dental row.

Tooth III (Tooth, Pl. Teeth): structure and functions

Tooth III, also known as a molar tooth, is one of the four types of teeth that are found in the human mouth. It is located at the back of the mouth and is designed to crush food before swallowing it.

Each tooth consists of a crown and a root. The crown of the tooth is located on the surface of the gum and is covered with hard enamel, which is the hardest material in the human body. The root of the tooth is located in a bony cavity called the dental alveolus, and is secured in it by the periodontal membrane.

Dentin, which surrounds the tooth cavity and protects the nerves and blood vessels, fills most of the tooth. The pulp is located in the center of the tooth and contains blood vessels and nerves that nourish the tooth and provide sensitivity.

Tooth III, like other teeth, begins to develop in an embryonic state. Tooth formation occurs when embryonic cells begin to come together to form a tooth germ. Then the process of mineralization begins, resulting in the formation of hard enamel.

In addition to the molar tooth, the human oral cavity also contains incisors, canines and small molars. Each type of tooth has its own characteristics and performs specific functions when chewing and swallowing food.

Overall, teeth are important for proper digestion and oral health. Regular dental hygiene, including brushing and professional cleanings, is an important part of maintaining healthy teeth and gums.

Tooth III is a hard structure of the oral cavity used for grinding food. It is found in every person's mouth and plays a vital role in our lives. How does it look and work from the inside?

1) Teeth III are located in the jaws - upper and lower. They are located in pairs next to each other. Inside each jaw there is a special bone canal - the alveolar arch. Teeth III grow inside this canal, just like any other.

2) The outer part of the tooth contains enamel. This layer protects the tooth from external irritants. The lower part of the tooth is immersed in the alveolar arch and covered with a cementing layer. The tooth consists of bone tissue - dentitis. The internal cavity of the tooth is occupied by many nerve endings that feed it. Nutrition comes through the roots of the tooth. They are deeply hidden in the inner layers of the jaw. So
