What is the reason why new teeth do not fall out during the tooth replacement period? How to deal with it?

The tooth replacement period is a very important period for children. If the teeth can be replaced smoothly during this period and there are no other problems, the child will have a set of white and clean teeth in the future. However, during the process of children's tooth replacement, such abnormal phenomenon may occur: the deciduous teeth have not fallen out, but new teeth have grown. What is the reason for this? Let me introduce you to this knowledge below!

1. Why do children grow new teeth before their baby teeth fall out ?

During the tooth replacement process, some children's deciduous teeth have not fallen out yet, but their permanent teeth have already grown. Some parents believe that this is due to too much calcium. In fact, this situation has little to do with the amount of calcium. The main reason is that the deciduous teeth are arranged very closely, while the permanent teeth are relatively large. The original position of the deciduous teeth cannot accommodate the new teeth, so the new teeth cannot grow normally directly below the deciduous teeth, resulting in the roots of the deciduous teeth not being absorbed, and the old teeth do not fall out but the new teeth have already grown.

2. What to do if new and old teeth coexist ?

First of all, parents and friends should understand that this situation is a common phenomenon and many parents will encounter it. Therefore, don’t be anxious, and don’t deal with it by yourself. If the old teeth become loose, wait and see. If the teeth show no signs of looseness, go to the hospital’s dental department for tooth extraction in time to avoid affecting the normal growth of new teeth.

Dentists point out that when children have both new and old teeth when they are changing their teeth, the deciduous teeth should be extracted. After the deciduous teeth are extracted, the permanent teeth will slowly move to the original position of the deciduous teeth due to the pushing force of the tongue. At this time, if there is enough space, the permanent teeth can grow straight. If the alignment of old and new teeth is ignored, it may cause uneven tooth alignment or malocclusion, and it may also easily lead to tooth decay due to incomplete teeth cleaning. Therefore, parents should pay special attention to the overlapping of new and old teeth in children during their tooth replacement period and handle it correctly.

3. Notes

1. Parents should pay attention to their children's diet. They must make sure to match coarse and fine foods, meat and vegetables, to avoid their children's diet being too refined. Give their children more fresh vegetables and fruits, and more foods containing crude fiber, such as celery and beans, so that the deciduous teeth can fall out naturally through chewing.

2. Parents should let their children develop good personal hygiene habits and maintain oral hygiene in daily life. They should brush their teeth when they get up in the morning and before going to bed. They should rinse their mouths with clean water after meals to remove food residues in the mouth to avoid bacterial infection and oral diseases.

3. In daily life, parents should let their children eat more coarse grains and foods rich in crude fiber, such as corn, celery, leeks, various beans, etc. Eating more coarse foods can promote the development of alveolar bone. At the same time, regular oral examinations should be done.
