What is the timing of teeth replacement for children?

Many parents may think that children's tooth replacement is a trivial matter and they don't need to pay too much attention to it. In fact, this view is very wrong. Children's tooth replacement should not be underestimated, because the teeth that children replace are permanent teeth, which will accompany us throughout our lives. If we do not pay attention to it during the period when children are replacing their teeth, it will leave regrets for the children throughout their lives. Below we introduce the time sequence of children's tooth replacement.

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 By the age of 12 to 13, all the deciduous teeth have fallen out and have been replaced by permanent teeth.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

The above is an introduction to the chronological order of children's tooth replacement. Permanent teeth begin to grow at around 6 years old, deciduous teeth will gradually loosen and fall out, and all teeth will be replaced by permanent teeth by the age of 12 or 13. This stage is called the tooth replacement period. Note: During the period of children's teeth replacement, it is important to adjust their diet and avoid eating too hard food.
