Normal time for children to start changing teeth

We know that children are the apple of their parents' eyes. If a child has a problem, parents will certainly be very worried and don't know what to do. We suggest that parents should take good care of their children's bodies in daily life, carefully observe their children's every move, and pay attention to any abnormalities. Below we will introduce the normal time for children to start changing teeth.

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 By the age of 12 to 13, all the deciduous teeth have fallen out and have been replaced by permanent teeth.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 order and timing of tooth replacement are roughly as follows:

Number of teeth and time of tooth replacement

4 central incisors 6-7 years old

4 lateral incisors 8-9 years old

First pair of canines 4 at 10 years old

Single canine 4 11 years old

Second canines 4 12 years old

First molars 4 at age 6

4 second molars at 13 years old

Children usually start to change their teeth at the age of 5-6. The two lower incisors come out at the age of 6. At the same time, the first large molars come out behind the second deciduous molars, one on the upper and lower left and right, and the two lower deciduous incisors fall off. 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., and take good care of themselves during the period of tooth replacement.
