How many teeth do adults have?

Generally, a healthy adult has 28 to 32 teeth, 28 of which are essential. The other four are wisdom teeth. Not everyone will grow wisdom teeth, and some people may not grow wisdom teeth throughout their lives. Wisdom teeth are the 8th and last teeth on each side.

Clinically, teeth are divided into three parts: the crown, the root and the gum. The visible white part of the upper and lower teeth is called the crown, which is covered by enamel; the root is covered by cementum, and the root is the part in the alveolar socket; the gums refer to the part where the root and the crown meet.

Although some people may have more than 28 teeth, there are only 28 functional teeth, excluding wisdom teeth. Many adults will not grow wisdom teeth in their lifetime, so the number of teeth they have is 28. Some adults will grow 1 to 4 wisdom teeth, so the average number of teeth an adult has should be between 28 and 32.

Why do everyone have a different number of teeth?

Theoretically, an adult should have 32 teeth, distributed symmetrically on the left and right. The distribution of these 32 teeth is: 2 incisors, 1 canine, 2 bicuspids and 3 molars in each upper and lower row on each half. The four molars at the back are also called wisdom teeth, and some people do not grow wisdom teeth.

When one or two teeth fall out due to aging or external force, it will not have much impact on your health. They can be repaired by making porcelain teeth or wearing dentures. However, if the teeth fall out gradually and the number is less than 20, it will gradually affect the health of the body.

If a person has less than 20 teeth, the chewing function will inevitably be weakened, which means that the food eaten cannot be fully chewed, which will directly affect the gastrointestinal digestive function; in addition, the lack of teeth will also have a great impact on speech pronunciation. If any teeth fall out, it is best to repair them in time. Having more than 20 functional teeth has many benefits for the human body and helps prolong life.
