It is normal for children to start changing their teeth around the age of six, but it may also occur six months earlier or later, which is generally considered to be normal.
In general, children start to change their teeth at around the age of six, but due to individual differences, not every child starts to change their teeth at the full age of six.
It is generally recognized that it is normal for children to start changing their teeth around the age of six, but it is also possible that it may occur half a year earlier or later, and due to individual differences, it is normal for the timing of tooth replacement to be different. Tooth replacement usually lasts until the age of twelve or so, after which there will be no more tooth replacement.
If a child’s tooth replacement time is advanced or delayed seriously, it is recommended to go to the hospital in time to avoid delayed treatment.
