The time of tooth replacement in children

We will all experience tooth replacement in the course of our lives. Many people do not know much about the knowledge about tooth replacement, but as parents, it is good for children's tooth replacement to know more about this knowledge in daily life. So when is the time for children to replace teeth? Below we will give you a detailed introduction on this issue. We also hope that parents can understand and learn about it, which will also help their children when it is time for them to replace their teeth and reduce the harm caused by children's tooth replacement problems.

Children usually start to lose their teeth around the age of 6. The physiological shedding of the first deciduous tooth usually occurs around the age of 6, but it can also occur as early as 4 years old, or as late as 7-8 years old, so there is no need to worry. Naturally fallen deciduous teeth have no roots and the fallen surface appears eroded. Parents should pay attention to observe and not confuse them with broken roots of deciduous teeth.

People grow teeth twice in their life, namely deciduous teeth and permanent teeth. There are 20 deciduous teeth, which usually start to erupt around 6 months old and are fully grown at 2-3 years old. There are 28-32 permanent teeth (the number of wisdom teeth is 0-4), which usually start to grow around 6 years old and 28 are fully grown at 12-13 years old (wisdom teeth vary from person to person). Therefore, the tooth replacement period is usually between 6 and 12 years old. There are certain rules for tooth replacement. Simply put, it is a certain time and a certain order, following the principle of "left-right symmetry, first lower and then upper". Left-right symmetry, first lower and then upper refers to teeth with the same name.

There are two different opinions about which permanent tooth grows first in children. One is that the first permanent molar that usually grows around the age of 6 grows close to the last deciduous molar, called the sixth-year molar, which erupts slightly earlier than or at the same time as the lower central incisor. Another theory is that children first replace the two middle front teeth in the lower row. Dentists say that this may be different for each child. Children grow upper central incisors and lower lateral incisors at the age of 6-8, upper lateral incisors at the age of 8-9, first and second bicuspids at the age of 10-12, and permanent canines at the age of 10-11.

Children are a large group of people with quite a lot of problems in our lives. They will go through the process of changing teeth in their lifetime. Some parents are not very clear about this, especially the time when children change teeth. The above is a detailed introduction to the time when children change teeth. I hope that parents can learn more in daily life, which will be very helpful to their children when their children change teeth.
