What should I do if my child's teeth haven't fallen out and new teeth have grown?

Children may encounter various problems when they are growing teeth. Parents should pay attention to these problems and help their children solve them. This will make their children's teeth grow beautifully and avoid growing crooked, which will affect their personal image and temperament when they grow up. Some children may have new teeth growing without losing their teeth. What do parents need to do at this time? Let’s see what the doctor says.

1. Remove baby teeth as soon as possible

When children have both old and new teeth when they are changing their teeth, the deciduous teeth should be extracted; Reason: Because the fallen deciduous teeth have no roots, the fallen surface appears eroded. After the deciduous teeth are extracted, the permanent teeth will slowly move to the original position of the deciduous teeth due to the push of the tongue. At this time, if there is enough space, the permanent teeth can grow straight; Misconception: If the juxtaposition of deciduous teeth and permanent teeth is ignored, it may cause uneven teeth arrangement or malocclusion, and it is also easy to cause tooth decay due to incomplete teeth cleaning.

2 It is best to take your child to see a doctor in time:

The doctor decides whether to extract the deciduous teeth. What should you do if the deciduous teeth do not fall out and the new teeth grow out? If parents encounter a child whose deciduous teeth do not fall out when the permanent teeth have erupted, they should take the child to the hospital for examination and treatment in time. Whether to extract the retained teeth when the permanent teeth have erupted but the deciduous teeth have not fallen out should be left to the doctor to judge. Generally speaking, it is better for deciduous teeth to fall out naturally. For those who have exceeded the age of tooth replacement but their deciduous teeth have not fallen out and permanent teeth have not erupted, they should not be extracted easily, because the deciduous teeth need to occupy space waiting for the permanent teeth to erupt. However, if the normal position of the permanent teeth is affected, they should be extracted as soon as possible to avoid affecting the eruption of the permanent teeth in the normal position.

3 What are the hazards of retained deciduous teeth?

"Retained deciduous teeth" refers to the situation where the permanent teeth have erupted but the deciduous teeth have not fallen out on time. Retained deciduous teeth occupy the normal position for the eruption of permanent teeth, and the permanent teeth may erupt ectopically, affecting the development of the normal occlusal relationship of the dentition. In particular, retained deciduous teeth or residual roots can lead to plaque retention and food impaction, which will affect oral hygiene and increase the chance of adjacent teeth developing caries. The residual roots of deciduous teeth retained due to chronic apical periodontitis can injure the surrounding mucosal soft tissues, and in severe cases can cause bedsores.

Causes of retained deciduous teeth

1. The abnormal eruption direction of the permanent teeth causes the roots of the deciduous teeth to not be absorbed or to be absorbed incompletely.

2. Congenital missing permanent teeth can cause slow absorption of the roots of deciduous teeth and cause retention.

3. The periapical lesions of deciduous teeth destroy the alveolar bone and cause the permanent teeth to erupt prematurely, while the deciduous teeth can also be retained and not fall out.

4. The permanent teeth are unable to erupt and the roots of the deciduous teeth are not absorbed.

5. The position of the permanent tooth germ is far away from the root of the deciduous tooth, which may also cause the deciduous tooth to be retained.

6. Certain genetic factors cause multiple retained deciduous teeth.

7. The reason why some deciduous teeth are retained is unclear.
