What reason is child 15 years old die tooth still did not change

summary

Most people don't know about it, and few of them come across it. But we still need to know. I'm 15 years old, and I haven't changed my die. I only changed my incisors and front teeth, and the ones close to my die still depend on extraction. Let's share some experiences.

What reason is child 15 years old die tooth still did not change

First: Generally speaking, permanent teeth erupt and replace deciduous teeth when children are about six years old, but some people have congenital permanent tooth germs missing, resulting in retention of deciduous teeth.

Second: permanent tooth germ exists, if it exists, it can induce the eruption of replacement deciduous teeth. If it does not exist and the deciduous teeth do not loose, it can retain the deciduous teeth.

Third: because the composition and structure of deciduous teeth are different from permanent teeth after all, it can not completely replace the function of permanent teeth, so it may need further treatment in the future.
