It is normal for permanent teeth to fall out and not grow out, and the loss of milk teeth may be related to factors such as apical periodontitis, abnormal development of permanent teeth, and chronic inflammation of the dental pulp.
1. Periapical inflammation: If there is caries in the lost milk teeth, after the formation of periapical inflammation, the permanent tooth germ may be infected, affecting the normal eruption, and there is a situation that the milk teeth have been lost for a long time but the teeth do not grow out.
2. Abnormal development of permanent teeth: some children have abnormal development of permanent teeth, such as permanent teeth obstruction, permanent teeth ambush, permanent teeth eruption position and former milk teeth conflict, congenital missing permanent tooth embryo and so on, there will be the case of teeth falling out but can not grow out.
3. Pulpitis: chronic inflammation occurs in the pulp of the lost milk teeth, the root is gradually shortened when the root canal is resorbed, and the permanent tooth loses the induction of the root of the milk teeth, so there will be difficulty in eruption or even directly buried in the jawbone and delayed growth.
When the symptoms of tooth loss do not come out, you should go to the regular hospital in time.
