A child’s missing tooth may be caused by fused teeth, congenitally missing teeth, or abnormal tooth eruption.
1. Fused teeth: two normally developing tooth germs are completely fused to form a fused tooth, resulting in the child having one less tooth. Fused teeth in the milk tooth row may also delay the physiologic resorption of the tooth root, preventing the eruption of the inherited permanent teeth.
2. Congenital missing teeth: affected by genetic factors, resulting in malformation of dental development, congenital missing teeth, resulting in the loss of individual teeth, and most often accompanied by a lack of hair, underdevelopment of nails and so on.
3. Abnormal tooth eruption: abnormal tooth eruption, such as late eruption or eruption difficulties, individual late eruption of milk teeth may be related to trauma or infection, late eruption of permanent teeth is mostly due to the premature loss of milk teeth caused by the displacement of neighboring teeth, resulting in insufficient space for eruption.
A child’s missing a tooth may also be caused by other reasons, parents are advised to take their children to the hospital in time for examination and targeted treatment after a clear diagnosis.
