The order of tooth development in children

Children's bodies need the care of their parents because the organs in their bodies are not yet fully developed. So we know that children's immunity and disease resistance are not strong enough. Parents must not only take good care of their children, but also need to learn some pediatric care knowledge, such as the order of children's tooth development. Below we will give you a detailed introduction to the order of children's tooth development.

Generally speaking, the development of teeth can be divided into three periods, namely the growth period, calcification period and eruption period.

Teething at 6 months is only the eruption period of tooth development. This complex process is not found in other organs of the body. For example, organs such as the liver and heart only have a growth period, while the skeletal system has two periods: growth and calcification. However, teeth not only need to calcify, but also need to erupt in order to perform their functions. These three steps are indispensable. Specifically, it is: the occurrence of tooth germ, the formation of tooth tissue and the eruption of teeth.

The development of tooth germs begins in the sixth week of embryogenesis, and 20 deciduous tooth germs gradually appear. While the deciduous tooth germs continue to develop, 20 permanent tooth germs grow from the lingual side of the deciduous tooth germs. In the future, they will develop into 20 permanent teeth and replace the deciduous teeth. The first, second, and third permanent molar germs grow at both ends of the permanent tooth germ in the tenth month of the embryo, two years after birth, and five years after birth, respectively. At this point the development of the tooth germ is complete.

Tooth formation, eruption and tooth germ development is a continuous dynamic process. From the time the tooth tip breaks through the mucosa and enters the oral cavity to the time it completely bites into the opposing tooth, this period of time is most likely to cause dental occlusion abnormalities. Because during this period, the tooth roots have not yet been fully formed, the periodontal attachment is not firm, and the alveolar bone is relatively loose and easily affected by external forces. Habits such as sucking fingers and biting lips can cause teeth to shift and become deformed. If malocclusion has already occurred, it must be corrected during childhood, otherwise the effect will not be ideal.

As children grow older, the number, size and strength of the periodontal tissues of their deciduous teeth can no longer adapt to the growing jaws and enhanced chewing power. The deciduous teeth begin to fall out physiologically at the age of 6, and are completely replaced by permanent teeth by around the age of 12.

Through the introduction in the above article, we understand the reasons why children's bodies are relatively fragile, so parents must take good care of their children in daily life. The above article introduces in detail the order of children's tooth development for parents.
