At what age is it normal for children to change their teeth?

Teeth are the most important chewing organs in a person's life. The quality of teeth is directly related to future eating problems, so people now pay more attention to children's dental problems during the period of tooth replacement. However, most parents do not know at what age it is normal for children to replace their teeth. When and what kind of teeth should children replace? Are there any precautions? Let me introduce to you in detail the issues related to children’s tooth replacement!

The age range from 4 to 12 is the period of tooth replacement, and it is normal at this age.

A person grows teeth twice in his life, once is the deciduous teeth, and once is the permanent teeth, which are adult 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. When the permanent teeth erupt, the deciduous teeth fall out one after another, and the time sequence is as follows:

At the age of 6, the two lower incisors come out, and at the same time, the first large molars, commonly known as molars, come out behind the second deciduous molars, one on the upper and lower left and right; the two lower deciduous incisors fall off.

At the age of 7, the two upper front teeth came out and the two deciduous front teeth fell out.

At the age of 8, the upper and lower incisors come out, and the upper and lower deciduous incisors fall out.

At the age of 9-10 years, the lower canines and the first bicuspids (one on each side, upper and lower) break out, and the lower deciduous canines and the first deciduous molars (one on each side, upper and lower) fall off.

At the age of 10 to 11 years, the upper canines emerge and the upper deciduous canines fall out (one on each side).

At the age of 11 to 12, the upper and lower second canines come out (one on each side), and the upper and lower third deciduous molars fall off (one on each side).

Generally, all the deciduous teeth fall out at the age of 12 to 13, and then only permanent teeth, namely molars, come out. The second molars come out at the age of 12, and the third molars come out at the age of 18, every 6 years, hence the name 6-year-old teeth. However, some people do not get these teeth until around 30 years old, and some individuals do not get them at all.

When children are changing their teeth, if the deciduous teeth do not fall out and the permanent teeth erupt on the side of the deciduous gums, which is the so-called double teeth, they should go to the hospital as soon as possible to extract the deciduous teeth, and the permanent teeth can quickly return to their original positions. In addition, if the deciduous teeth fall out early and the permanent teeth do not erupt for a long time, children will be accustomed to chewing food with their gums, and the gums will become keratinized and thickened, making it difficult for the permanent teeth to erupt. If the permanent teeth are close to the gums and the gums become dark and white, and the hard cutting edge of the teeth is touched under the gums during palpation, the gums at the cutting edge can be cut off to expose the cutting edge of the teeth, which will accelerate the eruption of the teeth.

In addition, children should eat more hard and crisp foods during the period of tooth replacement, such as steamed bread, dry bread, dry corn bread, vegetables, beans, etc., to stimulate the development of upper and lower jaws and promote the early eruption of permanent teeth.

It is a big deal for children to change their teeth, so as parents, we must pay attention to the problem of children's tooth replacement. If the child shows some symptoms during the tooth replacement, for example, new teeth grow out but the deciduous teeth do not fall out, then the child should be taken to the hospital to remove the deciduous teeth in time. Some children will have crooked teeth, and it is also necessary to correct them in time. Caring for children should start with the details.
