How many teeth are there?

Teeth are important organs for us to eat, but not everyone knows the common knowledge about teeth. The main reason is that these things are all in our mouths, and we rarely pay attention to them. If you don't know the number of teeth you have, you may not be able to detect any abnormalities in time. So, how many teeth do we have in total? Let’s take a closer look below.

There are 20 deciduous teeth in total, 10 in the upper and lower jaws. They begin to erupt around the age of birth and are fully grown at around two and a half years old. From the age of 7 to 12, the deciduous teeth will fall off one after another. There are 32 permanent teeth in total, 4 of which are wisdom teeth (third molars). Except for the wisdom teeth, all permanent teeth will erupt one after another around the age of 12. Wisdom teeth usually erupt after the age of 18, but not everyone can grow them out. Therefore, 28-32 permanent teeth are normal.

There are 28 teeth in the mouth that actually perform functions. Wisdom teeth do not have any function in the mouth. When the body's resistance is reduced or when getting angry, it is easy to cause tooth inflammation and unbearable pain. It is generally recommended to remove wisdom teeth, especially for female friends. If women have wisdom teeth, they are often prone to inflammation and pain symptoms during pregnancy, so it is generally recommended that female friends remove wisdom teeth before pregnancy.

When one or two teeth fall out, it will not affect the health of the whole body. However, when the teeth gradually fall out and there are less than 20 teeth left, it will begin to affect the functions of multiple systems of the body. At this time, if the fallen teeth are repaired in time and more than 20 functional teeth are kept in the mouth, the aging rate of the human body will slow down, which is beneficial to prolonging human life. This is because when a person has less than 20 teeth, food cannot be fully chewed, which affects the digestive function; the pronunciation of speech will be adversely affected, the appearance will appear old, and it will have a negative impact on the person's psychology. In addition, teeth are important organs of balance in the body. Many physical activities and concentrated mental activities require the coordination of teeth occlusion. When a person has less than 20 teeth, his or her balance function is affected, making him or her prone to making mistakes in activities and falling.

The above is an introduction to how many teeth there are in total. I hope it will help you understand. The number of teeth is basically the same, but there will be some changes in the number of teeth at different times. The overall situation will not change significantly. We can go to a regular dentistry for improvement based on our own situation. If there are any abnormalities, we can go to a regular dentistry for improvement.
