Why do children have sparse teeth?

Nowadays, children have more and more dental problems. Crooked teeth, tooth decay, etc. are very common problems. Moreover, many children's teeth grow sparsely and crookedly, so it is very complicated to treat them. This may be related to the eating habits and oral hygiene of today's children. But many parents don’t know the specific reasons. Let us now introduce the reasons why children have sparse teeth.

Congenital factors include genetic factors and the influence of the mother's internal and external environment during pregnancy. If the mother suffers from chronic diseases, malnutrition, metabolic disorders or lives in a polluted environment between the second month of pregnancy and birth, it will affect the formation of fetal tooth germs, resulting in an increase, decrease or deformity of the number of teeth.

In addition, genetic factors are also important. For example, if the parents' teeth are not aligned properly, the child's teeth may also have similar conditions. During the critical period of permanent tooth development from birth to 8 years old, the degeneration of chewing function is one of the main causes of malocclusion. Children nowadays eat more and more refined food, and parents care too much for their children. Their children mostly eat fine and soft food. Children are less and less willing to chew rough and hard food, which causes their chewing function to become weaker and weaker. The teeth and chewing muscles do not get proper exercise, resulting in muscle weakness and atrophy, and the jaw cannot develop well. Although the number of teeth has not decreased, the incidence of malocclusion is getting higher and higher. In addition, due to the lack of attention to the cleaning and care of oral teeth, caries are generated. In severe cases, the permanent teeth under the deciduous teeth are affected and their eruption is affected. If deciduous teeth are lost prematurely due to caries, resulting in insufficient space for permanent teeth to erupt, it will cause uneven teeth. In addition, bad oral habits, systemic or local chronic diseases, such as rickets, chronic rhinitis and chronic tonsillitis, can cause malocclusion.

The above introduces the reasons why children have sparse teeth, but this can still be prevented and treated. First of all, we should pay attention to children’s oral hygiene and eating habits. It is best to eat soft, easily digestible foods instead of hard foods. In addition, you should develop the good habit of rinsing your mouth after meals and brushing your teeth in the morning and evening.
