6-year-old Sweetie is a naïve little girl, his parents are busy working all day, from childhood she was pulled by her grandmother to grow up, fortunately, grandma's home and her own home is not far away, it is still very convenient to walk around.

Suddenly one day, Sweet covered her mouth and ran to Grandma's house crying, saying that her teeth hurt badly, Grandma was shocked after listening to it, and took a closer look, it turned out that Sweetie had grown double rows of teeth, so Grandma hurriedly took Sweet to the dentistry department of a nearby hospital, in order to make way for the newly grown permanent teeth, the doctor immediately pulled out Sweet's deciduous teeth.
And said: "This is a typical child's "double row teeth", also called deciduous teeth retention.
The doctor also said: "It is not uncommon for children like Tiantian to have "double rows of teeth", and many children, especially girls, have double rows of teeth. ”
First, there are 3 major reasons for children to grow "double rows of teeth"
In recent years, more and more children have grown "double rows of teeth", from kindergarten to primary school, so what is the reason for the "double rows of teeth"?
1. The child is overnourished, the tooth embryo develops relatively early, and the deciduous teeth have not fallen out, and permanent teeth have grown.
2. Now people are very particular about eating, food is too soft is not good, the root of the deciduous teeth can not get enough exercise and stimulation, it is not easy to fall off.
3. Do not pay attention to oral hygiene, resulting in deciduous tooth lesions, and when the situation is serious, it will cause the root absorption of deciduous teeth to be obstructed, resulting in loss.
Second, what kind of impact will double teeth have on children?
Under normal circumstances, when the child is 6 or 7 years old, the deciduous teeth have basically completed his task, it will automatically fall off, and then the permanent teeth will slowly erupt. But at this time, many children's permanent teeth have grown out, but the deciduous teeth are slow to "abdicate" and grow double rows of teeth, which are harmful to us as follows:
1. Affect your child's appearance
Teeth are an important part of human beings, a good tooth will also invisibly add a lot of points to you, if the child has a mouth, showing double rows of teeth, and crooked, not only is not good-looking, but also will cause ridicule from classmates, in the long run, it is not conducive to the development of children's physical and mental health.
2. Affect oral hygiene
Oral hygiene is very important, the deciduous teeth in the double row of teeth, it is easy to form a sanitary dead end in the mouth, and the food eaten will remain in it and will ferment and become smelly, thus forming tartar. It is also not conducive to our teeth cleaning, and a carelessness is likely to cause harm to our mouths.
3. Endanger your child's oral health
After all, double rows of teeth are not a normal situation, and children are likely to suffer from oral inflammation such as caries, pulpitis, and periapical periodontitis.
After seeing these hazards, a considerable number of parents will be very anxious when they see that their children have "double rows of teeth", and immediately ask the doctor to quickly pull them out.
In fact, it is not, whether it can be pulled out or not depends on the height of the permanent teeth, when the permanent teeth only grow out 1/3 or 2/3, it is recommended that parents let their children eat more hard foods, such as nibbling apples, nibbling corn, etc., in order to promote it to fall off naturally.
Extracting teeth too early is easy to cause deformities in the child's teeth and jaws, and the anesthetics used in tooth extraction will also cause pressure on the child to a certain extent.
Tip: Wait until your child's deciduous teeth fall out naturally. If there has been no "reaction" or other abnormal situations, take your child to the oral institution in time to ask a doctor for treatment.
3. How to prevent children from becoming double-rowed teeth?
1. Some experts remind that when children are still young, they should eat more soft and hard moderate foods to achieve a good stimulating effect on the deciduous teeth.
2. Children who are in the teeth replacement period should eat more coarse grains and unprocessed foods, this food can have an irritating effect on the deciduous teeth, promote the normal loss of the deciduous teeth, and encourage children to eat more hard and crude fiber foods.
3. Parents of children who are developing should always supervise their children to correct their children's bad habits, such as: biting their lips, biting their tongues, whistling, biting pencils, etc.
4. Develop good chewing habits. During the eating process, it seems that the most inconspicuous thing is chewing, but often it is also the most important because it can stimulate accelerated tooth root absorption of deciduous teeth. That is to say, if you give your child food that does not need to be chewed, it will often weaken his oral chewing ability and increase the chance of deciduous teeth remaining.
Therefore, when the child is about to change teeth, it is time to eat some food that needs to be chewed, so that it can exercise the child's teeth.
There will be more than 20 deciduous teeth in the child's life, the first permanent teeth will appear around the age of 5, and all the permanent teeth will be replaced after the age of 6, so the deciduous teeth are cyclical, and parents usually have to observe the child's mouth at all times, so as to avoid the child's double rows of teeth.
