What is the reason for not having teeth

summary

There are different manifestations in different people who don't have teeth. Some children are almost one year old and haven't had teeth yet. We should not take this symptom lightly. On the contrary, some children have teeth growing in their mouth not long after they were born, so parents are confused. How many months does the baby grow teeth? Why do some children have teeth later, but some are very early?

What is the reason for not having teeth

First, there are two pairs of teeth in a person's life, namely deciduous teeth (a total of 20) and permanent teeth (a total of 32). There is ossified deciduous tooth germ in the baby's jaw at birth. Under normal circumstances, the baby's first deciduous tooth erupts at 6-7 months. Due to the influence of genetic and other factors, the eruption of baby's deciduous teeth is early and late, and the individual difference is large. Therefore, we will find that some babies begin to have teeth at the age of four months, and some delay to 10-12 months, which belong to the normal physiological category.

Second: when the baby is more than one year old and still has no teeth, it can be regarded as abnormal. The main reasons are as follows: first, it is related to the baby's own nutrition and health. If the baby suffers from malnutrition, rickets, silly disease and other systemic diseases, it will delay the eruption of deciduous teeth. Secondly, it is related to the nutritional status of mothers during pregnancy and lactation. We know that the growth and development of deciduous teeth begin in the embryonic period. During this period, if the pregnant mother is malnourished, it is bound to affect the growth and development of deciduous teeth; and when the mother is malnourished during lactation, it will also affect the absorption of calcium and phosphorus of the baby, resulting in delayed teething of the baby. Thirdly, we should pay attention to a rare disease - congenital edentulism. This kind of children not only show edentulous or edentulous, but also accompanied by other organ abnormalities, such as sparse hair, dry skin, apocrine glands and so on. In addition, some oral tumors may also be harmful to teething.

Third: the child still has no deciduous teeth after ten months, and parents need not be too nervous. As long as the child is in good health and has no other problems, it doesn't matter if he has his first deciduous tooth when he is one year old. Pay attention to feeding, reasonable and timely add complementary food, more sun, baby's teeth will grow out naturally.

matters needing attention

Children who have their first teeth when they are one year old can ensure that their teeth will grow in turn in the future as long as they have no other problems, pay attention to adding mud paste food reasonably and timely, and get more sun exposure. Experts also pointed out that if the child is only one and a half years old, we should pay attention to find out the cause, such as whether it is rickets, whether it is accompanied by other abnormal conditions, we should go to the hospital for examination and treatment, must not abuse cod liver oil, calcium and other blind calcium.
