What is the reason for delayed tooth replacement in children?

Children will go through the stage of tooth replacement as they grow up. Generally, they start to replace their teeth at the age of 5 to 6. If a child does not start to replace his teeth until the age of 7, it may be due to calcium deficiency or poor tooth development. At this time, we should pay attention to the child's development, check whether the child's bones and height are too different from those of their peers, and supplement the baby with calcium in time.

1 Mainly related to individual differences, no need to worry too much

What is the reason for late tooth replacement?

Most children begin to change their teeth at the age of five or six, and some begin as early as four years old. Some children may not lose their first deciduous tooth until they are seven years old. This is caused by individual differences among children, so parents do not need to worry too much.

2 What is the reason for late tooth replacement: Is it due to growth retardation? What is the reason for late tooth replacement? It is related to growth retardation. Children lack calcium and have poor tooth development, which will lead to delayed tooth replacement in the later stage.

How to care: For the health of children's gums, mothers should give their children calcium supplements according to their conditions. Eating aquatic products such as fish, shrimp and crab can supplement calcium, drinking dairy products such as milk and soy milk can also supplement calcium, and drinking Longmu Zhuanggu Granules which have the effects of strengthening tendons and bones, harmonizing the stomach and spleen can also supplement calcium. While supplementing calcium, mothers should also pay attention to their children's diet. Do not let children eat delicate foods often. Let them eat chewy foods appropriately during the period of teething and tooth replacement.

3 What is the reason for late tooth replacement: retention of deciduous teeth is a common problem

What is the reason for late tooth replacement? The reason for late tooth replacement is that the deciduous teeth fall out too slowly, which is a common oral problem. Retained deciduous teeth can cause certain harm to the oral cavity. When permanent teeth grow out later and the deciduous teeth have not fallen out, it is easy to cause gaps between teeth and uneven tooth arrangement.

Recommendation: Mothers should pay close attention to their children’s gum health, learn more about the reasons why their children’s teeth change late, and take preventive measures early. If a child's permanent teeth erupt late or the permanent teeth are misplaced, the deciduous teeth should be extracted in time.

What causes retained deciduous teeth?

Abnormal eruption direction of permanent teeth

The eruption direction of permanent teeth is abnormal, resulting in incomplete root absorption of deciduous teeth. If this situation is found, the deciduous teeth have to be extracted and natural replacement can be completed with the help of human power. See a dentist promptly to have retained deciduous teeth removed. The newly formed permanent teeth will no longer have any resistance and will generally return to their normal position under the power of the lip, cheek and tongue muscles.

Congenital absence of permanent tooth germs

If permanent teeth are congenitally missing and there is no permanent tooth germ under the deciduous teeth, the root absorption cannot be promoted and the deciduous teeth will naturally remain on the gums for a longer time. Sometimes these remaining deciduous teeth do not fall out until adulthood and still have certain chewing functions.

The permanent teeth are weak to erupt and the roots of the deciduous teeth are not absorbed

As children grow older, parents should let them eat more chewy foods such as jellyfish, peanuts, sugar cane, spiced beans, etc. to maintain good stimulation to the deciduous teeth and promote their timely shedding.

Misalignment of permanent tooth germ

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, that is, it does not grow under the deciduous tooth, resulting in the permanent tooth and the deciduous tooth root cannot contact. Since the roots of deciduous teeth do not receive pressure or stimulation from permanent teeth, the roots are not absorbed and therefore do not loosen on the gums, causing the deciduous teeth to remain in the bed for a long time.

Adhesion of the deciduous tooth root to the alveolar bone

Due to inflammation, the roots of the deciduous teeth become adhered to the alveolar bone, resulting in incomplete or no absorption of the roots of the deciduous teeth, which prevents the deciduous teeth from falling out.

Premature extraction of deciduous teeth

The soft tissue at the missing tooth site often rubs against food, causing the gingival mucosa to thicken and become tough, thereby increasing the resistance to the eruption of permanent teeth and causing delayed eruption of permanent teeth. Diseases of deciduous teeth can cause infection around the tooth roots, leading to necrosis of the permanent tooth germs; or damage to the permanent tooth germs due to trauma to the deciduous teeth.
