Should children's double rows of teeth be extracted?

Double rows of teeth mainly appear in children during the tooth replacement period. Nowadays, more and more children have "double rows of teeth". The so-called double rows of teeth refers to a state in which permanent teeth erupt and deciduous teeth are retained, and the two types of teeth exist at the same time. So, do children with "double rows of teeth" need to have their teeth extracted? The editor below will introduce you to the relevant information about double rows of teeth, and mothers can refer to it to decide whether they need to have their teeth extracted.

What is "double row of teeth"

During children's tooth replacement period, the shedding of deciduous teeth and the eruption of permanent teeth are closely related. When a child is six or seven years old, the deciduous teeth have basically completed their mission and fall out automatically, and then the permanent teeth gradually erupt. However, for some children, the permanent teeth have already grown out, but the corresponding deciduous teeth are reluctant to "give way to others", so the permanent teeth are forced to "compromise" and erupt from the back, forming a double row of teeth, one in front and one behind. In dentistry, this condition is called retained deciduous teeth.

Causes of double row of teeth

First, overnutrition. With good nutrition supply and early tooth germ development, permanent teeth can't wait to emerge before the deciduous teeth fall out.

Second, eat a fine diet. The food is too soft and fine, and the roots of the deciduous teeth are not sufficiently stimulated and exercised, so they are closely connected to the alveolar bone and are not easy to fall off.

Third, lesions of deciduous teeth. If caries occurs in deciduous teeth, in severe cases it will cause root absorption disorders, resulting in the deciduous teeth not falling out in time.

It is wrong to say that "baby teeth will fall out naturally and do not need to be extracted"

"Double rows of teeth" are generally most common in children aged seven or eight, usually occurring in the lower teeth, but there is also the phenomenon of double rows of teeth in the upper teeth. The Dongguan People's Hospital outpatient department alone sees 200 such young patients every month.

From a clinical medical point of view, the appearance of double rows of teeth is due to the deviation in the position of the permanent top deciduous teeth. If double rows of teeth are not treated in time, it may induce other problems. Generally speaking, the hazards of "double row of teeth" are as follows:

This causes abnormal eruption of new permanent teeth, affecting the child's jaw development, chewing function, and facial appearance. Retention of deciduous teeth in the upper jaw is most likely to cause an underbite, also known as "underbite", while the most common problem in the lower jaw is misaligned teeth.

It is not conducive to teeth cleaning. Food residues retained between teeth can easily form dental plaque and tartar, leading to bad breath.

It may induce oral inflammatory diseases such as caries, pulpitis, and apical periodontitis.

If inflammation occurs, local chronic inflammatory lesions containing bacterial microorganisms will carry the bacteria and their toxins to other organs and tissues through blood vessels and lymphatic vessels. When the body's resistance is reduced, these tissues and organs far away from the affected teeth may also become diseased, causing a series of diseases in the body such as myocarditis, nephritis, endocarditis, eye diseases, rheumatoid arthritis and other problems.

Many parents believe that "baby teeth will fall out naturally and do not need to be extracted." This is wrong. It mainly depends on the time when permanent teeth erupt and the time when baby teeth fall out.

Should I extract the double row of teeth?

Whether to extract a tooth or not depends first on the height of the eruption of the permanent teeth. When the permanent teeth have only erupted 1/3 or 2/3 and the front teeth have not yet loosened, parents are advised to be patient and let their children eat more hard foods, such as chewing apples, biting corn and other physiological stimulations to promote natural shedding.

If the permanent teeth have erupted but the deciduous teeth have not fallen out normally in time, the deciduous teeth that have not fallen out should be extracted. Because the deciduous teeth that have not fallen out will occupy the corresponding positions of the permanent teeth, causing the newly erupted permanent teeth to erupt laterally, resulting in misaligned teeth. If they are not removed in time, it will take three to four months to a year for them to fall off completely on their own, which will have a great impact on the growth of permanent teeth.

If there are other abnormal conditions, parents should take their children to see a dentist in time.

How to prevent children from having double rows of teeth

First of all, parents should gradually introduce their children to foods that are of moderate hardness and can be torn. For example, you can let your child chew on an apple, sugar cane, corn, peanuts and other chewy foods. This will maintain a good stimulation effect on the deciduous teeth and encourage them to fall out on time.

Parents should supervise their children and correct their bad habits, such as biting their lips, biting their tongues, whistling, biting pencils, etc.

Secondly, parents should let their children develop good hygiene habits and brush their teeth regularly. Eat less sweets and pastries, drink less high-sugar beverages, and rinse your mouth and brush your teeth promptly after eating.

Whether to extract the double rows of teeth should be analyzed based on the specific situation. If parents are not sure, it is recommended to take the child to a dental clinic or hospital for diagnosis and treatment in time and do not delay.
