At the beginning of adding complementary food, we should pay attention to cultivating children's chewing ability: at the beginning of adding complementary food, we should gradually change the nature of food, from muddy food to semi-solid food to solid food. After 1 year-old, hard and wear-resistant food should be gradually added, with the aim of strengthening chewing ability, fully exercising oral muscle function and effectively stimulating mandibular development.
/kloc-under 0/year-old, you need to ask a dentist to do the first oral health examination for your child. Correct children's bad oral habits such as sucking fingers, biting lips, sticking out tongue and unilateral chewing. Improve children's nutritional structure and actively treat children's basic diseases.
Whether children's dentition is neat or not, we should pay attention to two critical periods of children's tooth development from the critical period: the first critical period is from 2 months of pregnancy to birth, which is the development stage of deciduous teeth; The second critical period is from birth to 8 years old, which is the development stage of permanent teeth;
Parents can look at this period of time, the child's tooth development is actually the same as the bone development, and it is not necessary to wait until the teeth erupt from the gums to count as long teeth. In fact, the child's teeth begin two months after the embryo. Therefore, whether a child's dentition is neat or not should be paid attention to from the embryo.
The regularity of children's dentition is influenced by these factors: irregular tooth arrangement, abnormal relationship between teeth and adjacent teeth, and abnormal occlusion between upper and lower teeth, which is medically called malocclusion. The factors causing malocclusion are mainly related to genetic factors, maternal internal and external environment during pregnancy and acquired tooth development.
Internal and external environmental impact during pregnancy: If the mother suffers from chronic diseases, malnutrition, metabolic disorder or lives in a polluted environment from the second month of pregnancy to birth, it will affect the formation of fetal tooth germs, leading to the increase or decrease or deformity of baby teeth.
The order of tooth eruption is closely related to the arrangement of teeth: the physiological eruption of tooth development begins with a certain time, order and symmetry; The order of tooth eruption will determine whether the teeth are arranged neatly.
Genetic factors: Whether children's teeth are arranged neatly has a great relationship with their parents' heredity. If his parents' teeth are irregularly arranged, then the child's teeth are probably inherited from their parents' irregular arrangement.
Degeneration of chewing function: During the development of permanent teeth (from birth to 8 years old), parents always give their children too thin and soft food because they care too much about them, which makes them unwilling to chew rough and hard food for a long time, so that their chewing function is not exercised, so that their muscles are unable to atrophy and their jaws are stunted. Although there are many teeth, they will gradually form a malocclusion.
Not paying attention to oral hygiene since childhood: Some children have developed the oral hygiene habit of brushing their teeth since childhood, which will lead to dental caries and seriously affect the hereditary permanent teeth corresponding to deciduous teeth (deciduous teeth are replaced by corresponding permanent teeth), making them unable to erupt. If caries causes the destruction and shedding of deciduous teeth, the eruption gap of permanent teeth is insufficient, resulting in irregular tooth arrangement.
