2. Common sense of protecting teeth

Teeth are the hardest organs in the human body. It has the functions of biting, tearing and grinding food. There are two pairs of teeth in a person's life: one pair is deciduous teeth, with a total of 20 teeth. The other pair is permanent teeth, * * * 28 ~ 32, and the third molar usually erupts after 17 years old, also called wisdom teeth. Wisdom teeth will never come out.

Teeth are divided into three parts: crown, neck and root. The crown is the part we can see, and it is the part where the teeth are exposed outside the gums. The surface of the crown is covered with a layer of enamel, which is the hardest tissue in the human body, and its hardness is similar to that of the time. The root is embedded in the alveolar process of the upper and lower jaws. The root surface is covered with a layer of cementum. The neck of the tooth is a slightly thinner part between the crown and the root of the tooth, which wraps the gum. Teeth are mainly composed of dentin, and the internal cavity is called tooth cavity. The cavity of movable teeth is filled with connective tissue, nerves and blood vessels, which are collectively called dental pulp. Blood vessels and nerves enter and exit from the apical foramen of teeth. When suffering from dental caries, bacteria corrode enamel and dentin and enter the pulp cavity, which stimulates nerves and makes the pain unbearable.
