How old do children begin to change their teeth

summary

In the course of children's growth, tooth replacement is also a necessary stage. Therefore, many parents are very concerned about the problem of children's starting to change teeth when they are a few years old. Next, we will understand the problem of children's starting to change teeth when they are a few years old.

How old do children begin to change their teeth

First of all: children begin to change their teeth around the age of 6. Most of the physiological shedding of the first deciduous tooth occurs around the age of 6, but there are some as early as 4 years old, or as late as 7-8 years old, so there is no need to worry.

Second: people have to grow teeth twice in their life, namely deciduous teeth and permanent teeth. There are 20 deciduous teeth, which usually begin to sprout at about 6 months, 28-32 permanent teeth at 2-3 years old (the number of wisdom teeth is 0-4), and 28 wisdom teeth at 12-13 years old (the number of wisdom teeth varies from person to person).

Finally: Generally speaking, when children change their teeth, they also have certain regularity. In terms of time and order, they follow the principle of "left and right symmetry, first down and then up". Left and right symmetry is for the teeth of the same name.
