When do primary molars replace?

As we all know, when children reach a certain age, they will start to change their teeth for the first time. The teeth after the change are also called the first permanent teeth. There are four of these teeth, and they will accompany us throughout our lives. However, many parents do not know at what age the deciduous molars will be replaced by their children. So, when do primary molars replace?

First, when do the deciduous molars change? Children start to change their first permanent molars at the age of 6. There are four of them, also called sixth-year molars. For some children, the first permanent molars erupt early, while for some children, the permanent teeth below the front teeth erupt early. Its existence actually serves as a positioning system for other teeth, which means that other teeth are arranged according to its position. Moreover, the development of the sixth molars will affect the baby's facial shape, so it is important to protect them. The deciduous molars are usually replaced after the age of nine.

Second, if the second molar is a permanent tooth, the first permanent tooth usually appears around the age of six, and the deciduous teeth are replaced one by one by the same permanent tooth from the age of six to 12. Second permanent molars erupt at age 12. The third permanent molars erupt between the ages of 17 and 18, but there are also cases where the third permanent molars do not erupt throughout one's life. It will not change after it grows out, so you should protect it well. Do not eat sweets, and if you have tooth decay, fill it in time.
