When it comes to the ground bag day, many people's first impression is: the chin is convex forward, and the lower row of teeth covers the upper row of teeth.
Severe points will look sideways like a crescent face.
In medicine, there is a professional word called "anti-jaw", which is a common malocclusion deformity.
You may think, my child is still deciduous teeth, and the ground bag is afraid that the eight rods can't hit it, right?
Don't rush to make a conclusion, first look at a set of data, which was found by Fu Minkui, a well-known professor in the field of orthodontics:
The probability of a child having deciduous teeth covered in the sky is 14.94%.
This data is only a multi-tooth cover, if you add a single tooth to cover the sky, it is even higher.
△ Compiled from "Orthodontics", the above data are average
To say why children appear in the earth, the most direct reason, I am afraid is genetics.
According to "Pediatric Oral Medicine", nearly half of the people who have covered the sky will have a similar situation among one to three generations of blood relatives.
Yes, you read that right, this inheritance comes not only from parents, but also from parents' siblings, as well as the child's grandparents, grandparents and grandparents.
The habsburg family, which has a far-reaching influence in European history, is the family characteristic that is talked about by people, that is, the earth is wrapped up in the sky.
One person has taken all the family genes astray, and has to lament that the genes are really too powerful.

In addition to heredity, there are also some diseases that can affect the development of a child's jaws and teeth, resulting in a blanket of the earth, such as:
Congenital diseases: congenital cleft lip and palate, congenital loss of maxillary permanent teeth, etc.;
Systemic diseases: hyperpituitary gland, rickets, etc.;
Respiratory diseases: chronic tonsillitis, adenoidal hyperplasia, or hypertrophy.
Of course, these genetic and disease factors, to be honest, we can only resign ourselves to fate and seek help from doctors in time after discovery.
However, some acquired influencing factors can be changed, and the initiative is in our own hands.
As long as you pay more attention to it, you can reduce the probability of your child covering the sky.
1. Bad oral habits
For example, spitting out the tongue, biting the upper lip, eating hands, if the child has these habits from an early age, and maintained until the age of four or five, it is easier to cause the jaw to habitually extend forward, causing the ground to cover the sky.
2. Teeth cleaning habits
If the teeth are not brushed clean, the milk molar teeth are mothed or even fall off, the child will not be able to make it strong when chewing food, unconsciously use the front teeth to chew, and the jaw will be extended for a long time, which will also form a ground cover.
3. Bottle feeding habits in infancy
If the child is always lying down to eat the bottle, then his jaw needs to push forward hard to drink the milk. Over time, the jaw will protrude forward, forming a ground enveloping the sky.
In addition, the time to use a bottle or pacifier is too long, such as eating a bottle after the age of 1 and a half, and still using a pacifier after the age of 2, which will also increase the probability of wrapping up the day.
As for breastfeeding, there is currently no evidence that it leads to earth packing.
On the contrary, the child's sucking method of squeezing the areola with the tongue and palate will promote the development of the upper jaw and jaw, reducing the possibility of the occurrence of the earth.
A 2016 article published in The Lancet also showed that breastfeeding can reduce dental misalignment by 68%.
If the child has a floor, in addition to what we said earlier, it will affect the development of the child's upper and lower jaws, the posture of extending the chin and the back, and because the upper and lower front teeth do not coincide, the child cannot use the front teeth to cut off the food, and even the noodles are bitten continuously.
At this time, if you are still holding the fluke psychology of "the baby teeth are fine, it should be fine after changing your teeth", you can quickly dispel it.
If the face is already deformed, you take the child to correct it, it will be much more complicated, and some may have to do orthodontic surgery in adulthood, costing tens of thousands or even hundreds of thousands.
"Orthodontics" said that if the deciduous teeth are not treated, more than half will develop into permanent teeth and the symptoms will be aggravated. You see, dragging on all the time is really not worth the loss!
Therefore, Professor Peng Youjian, an early orthodontic expert on dental and jaw deformities in China, advocated: "Anti-jaw is an emergency department, and it is corrected when it is found." ”
If the child has land, he needs to be treated as soon as possible, and cannot wait until the teeth are replaced.
Generally, 3 to 5 years old is the best age for corrective teeth.
Because at this time, the child already has a certain degree of cooperation, the root of the deciduous teeth has also been developed, and the bone elasticity is large, and it is easier to correct.
If the doctor checks and finds that the child is mildly wrapped up caused by bad oral habits, the correction is relatively fast, usually about half a year can put the teeth back in place.
△ After the deciduous teeth are corrected, the child's posture of stretching the chin and back will be corrected
If the child appears during the tooth change period, that is, 6 to 12 years old, it also needs to be corrected, but it is slightly more troublesome than the deciduous period correction, and generally 6 to 8 years old is the best age for the tooth change period.
If the first two periods are missed, the child's teeth have all been replaced around the age of 12, the upper and lower jaws have basically developed and formed, and it will be much more difficult to correct at this time, and the effect will be worse, and the serious situation may have to wait until adulthood to do orthodontic surgery.
Straightening teeth is not an easy task for children.
If it is good to say that he is not willing to correct, don't be too entangled a day earlier, a day later, usually do more communication work for the child, talk about the benefits of teeth correction, and wait until his psychological endurance is stronger.
If your child doesn't have a place to go right now, it's best.
But also do a good job of prevention, after all, the child's growth changes a lot, to experience jaw growth, tooth replacement, who knows what will happen later!
Usually pay more attention to whether he has bad oral habits such as spitting out his tongue, biting his upper lip, and eating his hands;
Daily oral cleaning must be in place;
Regular teeth check-ups every 3 to 6 months;
For a child who is still eating a bottle, try not to feed him lying down. After 6 months, he began to help him quit bottles and pacifiers, no more than 1 and a half years old at the latest, and no more than 2 years old at the latest.
To a certain extent, these can play a preventive role, and I hope that each child's teeth can be neat and tidy all the time.
If the child's teeth appear to cover the sky, it will not only affect the facial appearance, but also affect the body shape of the whole person, and even eating will have problems!
Therefore, parents whose children are in the period of teething or teething replacement must observe the child's situation more, once they miss the best correction period, there will be a lot of trouble later.
