At what age do children usually start to lose their teeth?

I believe everyone must know what tooth replacement is. Tooth replacement means that our deciduous teeth fall out and permanent teeth grow. The process of tooth replacement is very long, and there must be no problems during the process, otherwise we will leave regrets for the rest of our lives. Tooth replacement usually occurs when we are very young, so parents need to do a good job of caring for children's tooth replacement.

Tooth replacement is the process of deciduous teeth falling out and permanent teeth growing in. During the growth and development process, there is a permanent tooth germ under the root of each deciduous tooth, which gradually develops and grows. During the eruption of the permanent tooth, on the one hand, it compresses the alveolar bone between the deciduous tooth root and the permanent tooth germ, and through the action of osteoclasts, the bone is absorbed and thinned until it is completely absorbed; on the other hand, it directly compresses the deciduous tooth root, causing the deciduous tooth root to gradually absorb, become shorter and shorter, until it disappears completely. Then the deciduous teeth begin to fall out and the permanent teeth gradually grow in.

Normally, at the age of 6 to 7, the deciduous central incisor (central front tooth) of the mandible begins to shake and fall out, and soon the permanent central incisor grows in this place; at the same time, the first molar grows behind the second deciduous molar. After that, the other teeth were replaced one after another. The permanent monocuspids and bicuspids can only grow out after the deciduous teeth in the same position fall out. By the age of 12 to 13, all the deciduous teeth have fallen out and have been replaced by permanent teeth. After that, permanent teeth will grow separately: the second molar will grow behind the first molar at the age of 12 to 14, and the third molar will grow after the age of 18. It is normal for some people to not have third molars.

The above introduces the general age of children. People who grow teeth grow twice in their lifetime, once for deciduous teeth and once for permanent teeth. The permanent tooth germs begin to develop and calcify after birth and start to erupt at the age of 6-7. There are 32 permanent teeth in total, and they are usually fully erupted by the age of 20. The deciduous teeth fall out one after another when the permanent teeth erupt.
