Please see the detailed introduction below.

Below the root of each of the child's deciduous teeth, there is a permanent tooth germ that gradually develops and grows toward the mouth. During the eruption of permanent teeth, on the one hand, they compress the alveolar bone between the roots of deciduous teeth and the permanent tooth germs, and through the action of osteoclasts, the bone is absorbed and thinned until it is completely absorbed.

But on the other hand, it directly compresses the roots of the deciduous teeth, causing them to gradually absorb, become shorter and shorter, until they disappear completely. Then the deciduous teeth begin to fall out and the permanent teeth gradually grow in. However, if for some reason the roots of the deciduous teeth cannot be completely "eaten" or absorbed, the deciduous teeth that should fall out may not fall out.

Why do children’s baby teeth not fall out? There are several reasons why children's baby teeth do not fall out:

1. Misplacement of permanent tooth germs: When the position of permanent tooth germs is abnormal, there is no or little contact between the misplaced permanent tooth germs and the roots of deciduous teeth, and they cannot completely compress the roots of deciduous teeth, causing the roots of deciduous teeth to be unable to be absorbed or to be absorbed slowly, resulting in retention of deciduous teeth.

2. Local inflammation: The permanent tooth germ may be necrotic due to infection, or the root of the deciduous tooth may be adhered to the alveolar bone due to inflammation. The root of the deciduous tooth may be incompletely absorbed or even not absorbed at all, resulting in the loss of deciduous teeth.

3. Missing permanent tooth germs: Due to the congenital missing permanent tooth germs, the roots of deciduous teeth are not subjected to pressure stimulation and are not absorbed, so the deciduous teeth remain on the gums. These remaining deciduous teeth sometimes do not fall out until the age of 30 or 40, and they still have a certain chewing ability.

What should I do if my child’s baby teeth don’t fall out? When faced with the problem of children's deciduous teeth not falling out, parents should take their children to the hospital for examination and treatment in time. Retained teeth that have erupted but have not fallen out should be extracted as soon as possible to avoid affecting the eruption of permanent teeth in the normal position. If your baby's deciduous teeth have not fallen out and permanent teeth have not erupted after reaching the age of tooth replacement, do not extract them easily. If your permanent teeth are congenitally missing, you should try to keep the deciduous teeth.

The above is an introduction to why children’s deciduous teeth do not fall out. I believe that after reading the above introduction, you will have a better understanding of the reasons why children’s deciduous teeth do not fall out. In fact, there are many reasons why children’s deciduous teeth do not fall out. Therefore, once parents find that their children’s deciduous teeth do not fall out, they should see a dentist in time to find out the reason before taking the next step.
