The regenerative capacity of human organs is very weak. Without a small piece of teeth, you can't grow well; If a permanent tooth falls out, it won't grow back.

The small gaps in the teeth are filled with food scraps and dental plaque, and the tongue has instructions and can't feel them. In this way, under the action of residue and bacteria, the small holes will become bigger and bigger, and finally become cavities. Therefore, it is recommended to go to the dentist early and use a better plan to repair it, so as to avoid getting worse and worse and eventually rotting.
