What is the process of children's tooth replacement?

I remember when I was a child, I was often laughed at by others because of my falling teeth. If it was a big front tooth, I would leak when I spoke, so adults would always pinch my face and tease me. In fact, every child's tooth replacement is a process. There are also many things to pay attention to when replacing teeth, otherwise it is easy for your teeth to be uneven or have one more or one less. So when exactly do we change teeth?

Generally, at the age of 6, the first permanent tooth begins to erupt just behind the deciduous dentition, which is medically called the "sixth year tooth". After that, the deciduous teeth continue to fall out and the permanent teeth erupt one after another.

◇ 6 years old: The two lower incisors come out, and at the same time, the first molar comes out behind the second deciduous molar, one on the upper and lower left and right sides; the two lower deciduous incisors fall off.

◇ 7 years old: The two upper front teeth come out, and the two upper deciduous front teeth fall out.

◇ 8 years old: The upper and lower incisors come out, and the upper and lower deciduous incisors fall off.

◇ 9-10 years old: Lower canines and first pair of canines (one on each side) come out.

The lower deciduous canines and first deciduous molars (one on each side, upper and lower) fell off.

◇ 10-11 years old: The upper canines emerge and the upper deciduous canines fall out (one on each side).

◇ 11-12 years old: The second canines of the upper and lower teeth come out (one on each side), and the third deciduous molars of the upper and lower teeth fall out (one on each side).

◇ 12-13 years old: All the deciduous teeth fall out, and only permanent teeth, namely molars, will come out.

(The second molars come out at the age of 12, and the third molars come out at the age of 18, once 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.)

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

Therefore, you can see that teeth often start to change when children are young and ignorant, so parents should teach their children to be careful not to lick their teeth with their tongues when they are changing their teeth; more importantly, sometimes when the gum roots have not fallen off, do not pull them out forcibly to avoid unclean teeth falling out.
