What causes late teething in children?

After the baby is born, as the baby grows older, the body will usually undergo different changes at different stages. When the baby grows to a certain period of growth, teeth will grow. Some babies grow teeth later, while some babies grow teeth earlier. In fact, there are many reasons for the baby's late teething, which can be divided into physiological and pathological reasons. Parents need to learn to distinguish them and promptly investigate the reasons for the baby's late teething.

What is the reason for delayed teething in babies?

The early or late eruption of children's teeth is mainly determined by genetic factors. Usually children start to grow teeth when they are 6 to 7 months old. Children with early teething start growing teeth at 4 months, and children with late teething do not start growing teeth until around 10 months. Some children do not grow their first deciduous tooth until after 1 year old. This situation is related to the speed of bone growth during infancy.

Late teething means that the child's bone growth is slower, while early teething means that the child's bone growth is faster. Of course, this is relative. As long as late tooth eruption is not caused by calcium deficiency or disease, it generally will not affect the future growth and development of bones. A child's height growth mainly depends on the growth of long bones (bones of the limbs). The growth of long bones mainly takes place in the cartilage tissue between the epiphysis and epiphysis at both ends of the bone shaft.

Some parents, when they see that their children do not have teeth when they should, think it is due to calcium deficiency, and they give their children cod liver oil and calcium tablets. This is not advisable. Whether to supplement calcium for children should be decided mainly based on the child's actual physical condition. A child's late teething does not necessarily mean that he is calcium deficient. The decision should be made based on a comprehensive analysis of the examination and the symptoms exhibited. Calcium deficiency in children is often manifested by slow closure of the fontanelle, thinning hair, excessive sweating, crying, etc. At this time, it is beneficial to the child's health to supplement with some calcium preparations and cod liver oil drops under the guidance of a doctor, and pay attention to the proper supplementary food.

Baby teething precautions

The first deciduous tooth should erupt when the child is about 6 months old. If a child is over 1 year old and has not yet grown his first deciduous tooth, it is called late eruption of deciduous teeth.

The most common cause of delayed eruption of primary teeth is vitamin D deficiency rickets. Extreme malnutrition, cretinism (congenital hypothyroidism), and congenital syphilis are also causes of late eruption of deciduous teeth. If a child is over 1 year old and still has not grown teeth, parents should take the child to the hospital for treatment. If the child still has not grown teeth after taking calcium supplements and vitamin D and other diseases have been ruled out, the child should go to the hospital for an X-ray to determine whether there are tooth germs in the gums. If there are tooth germs, the teeth will grow sooner or later. If there are no tooth germs, the problem of adontia should be considered.

There is also the problem of absorption when supplementing calcium. No matter how much you take, it will be useless if it is not absorbed. The key is to supplement sufficient amount of vitamin D, and the best way is to bask in the sun. It can be said that rickets in children is not only caused by calcium deficiency, but also by lack of "sun exposure". 7-dehydrocholesterol in the skin can be converted into vitamin D when exposed to ultraviolet rays, which promotes calcium absorption and makes bones strong. The specific situation should depend on the season. Baby's skin is delicate and should be protected. In summer, you can choose to do it under the shade of a tree or with an umbrella, or just after the sun comes out or before sunset; in spring and autumn, you can take your children to play outdoors often.
