Why do I only have one front tooth? Cry! Good man, come on.

If that tooth fell out for the first time, it means that it is a deciduous tooth and will grow back.

In 2003, you were 6 years old and met the requirements for changing deciduous teeth.

But like you, if you haven't grown for six years, you need to go to the hospital for examination. I won't laugh at you. The problem you are worried about may really exist. It is said that you should have a physical examination after two years of not growing up.

So personally, I suggest you go to the hospital to see if there is something wrong with the root, or, as you said, the tooth next to it can't grow out.
