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

As we all know, teeth play a very important role in us. If there is a problem with our teeth, it will not only easily affect our diet but also bring us a lot of psychological pressure. Therefore, we must protect our teeth well in daily life. The teeth we have are permanent teeth, which start to grow when we are very young. Below we will introduce at what age children usually start to change their teeth.

Generally speaking, children's teeth change in a symmetrical manner, with the upper and lower rows of teeth changing first and then the lower ones. The order of children's tooth replacement is as follows: the first permanent tooth, i.e. the central incisor, begins to grow when the child is 6-8 years old, and the first molar also grows slowly; when the child is 8-9 years old, the lateral incisor begins to grow; the bicuspids of children aged 10-12 begin to grow, and the first bicuspid will grow first, which is next to the lateral teeth; when the child is 11-12 years old, the upper and lower canines have gradually grown; children aged 12-13 begin to grow second molars; the last third molar, i.e. wisdom tooth, will not start to grow until the child is 17 years old, and will continue to grow until the age of 21, which varies from person to person.

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's teeth usually start to fall out at around 6 years old, and then permanent teeth grow. Girls' teeth grow earlier than boys, so families with boys don't need to worry. During the teething period, children should also pay attention to eating more calcium-rich foods, avoid eating raw, cold, and hard food, and eat more foods rich in vitamins.
