At what age do children usually start to lose their teeth?

As we all know, children need to change their teeth when they reach a certain age. If an accident occurs during the period of tooth replacement, it will leave regrets for the child for the rest of his life. Therefore, parents and friends may wish to pay more attention to the issue of children's tooth replacement. Although many parents know that children's tooth replacement is very important, they don't know what they should do about it. In the following article, we will give parents and friends some scientific knowledge about at what age children generally start to change their teeth.

At what age do children start to lose their teeth?

Teeth change around 6 years old

Generally speaking, deciduous teeth will become loose and fall out before children enter elementary school, and at the same time, permanent teeth will also show signs of eruption. Generally speaking, the first deciduous tooth falls out when the child is 6 years old. Of course, this is not a definite number, because some children's deciduous teeth begin to fall out when they are over 4 years old, and some begin to fall out when they are 7 to 8 years old, so parents do not need to worry too much.

Human tooth growth rules

Most people have only two sets of teeth in their lifetime, namely deciduous teeth and permanent teeth. From the time your baby is six months old until he is two or three years old, his 20 baby teeth will gradually develop completely. The permanent teeth will gradually replace the deciduous teeth between the ages of 6 and 13, and then several molars will continue to erupt, eventually reaching 28-32 teeth (some people do not grow 4 wisdom teeth).

The order in which children change their teeth

In general, the teeth in the lower half of children will fall out before the upper half, presenting a symmetrical situation on the left and right. Therefore, at about the age of 6, the child's lower deciduous central incisors gradually become loose and fall out, and the lower permanent central incisors and first permanent molars also begin to gradually erupt.

Afterwards, the deciduous canines and bicuspids will slowly fall out one by one and be replaced by corresponding permanent teeth. When children reach the age of 12-14, all their deciduous teeth will be replaced, and then the permanent teeth will grow separately. The second molars grow out between the ages of 12 and 14, while the third molars, commonly known as wisdom teeth, only start to grow after adulthood.

The above introduces the time when children replace their teeth. Children's deciduous teeth are generally replaced at around 6 years old, but there are certain differences between boys and girls. Generally, boys develop slightly slower than girls at this age, and the eruption of boys' permanent teeth is also relatively later than that of girls. This is a normal physiological reason.
