<1> Irregular teeth are medically called dentofacial deformities. How did the dentofacial deformity come about? Generally speaking, there are two reasons: congenital and acquired. Pregnant women do not pay attention to nutrition and health, some diseases and fetal development, which is the congenital cause of tooth deformity. Infant's diet care, stunted growth, premature loss of deciduous teeth and some bad habits are the acquired causes of tooth deformity. ?
In fact, whether congenital or acquired, the most important thing is that our parents don't know enough about children's oral health care and ignore some common sense problems.
< 2 > If you want your child's teeth to be healthy, you should pay attention during pregnancy. Some people think that pregnant women should look at more photos of handsome men and beautiful women, and the children born must have correct facial features and strong speech. Actually, this is unscientific.
In recent years, medical workers at home and abroad have proved that sound, light, mother's movements and emotions are directly related to the development of the fetus, especially in the 7~ 10 week of pregnancy. If the pregnant woman is emotionally unstable or traumatized, the baby may have head and facial deformities. Moreover, pregnant women's monotonous food, or poor food, or eating less fruits and vegetables will also affect the normal development of fetal teeth. After the baby is born, his teeth often come out late, and the teeth that grow out often tilt off, lose smoothness and are prone to dental caries. In addition, in order to avoid adverse effects on the fetus. Pregnant women should think more about beautiful things, listen to relaxed and healthy music or songs, and talk more about topics that are beneficial to physical and mental health. This is not only conducive to the healthy development of the fetal brain, but also makes the future baby have correct facial features and strong speech.
If our parents are afraid that their children's digestion and absorption function is not strong, but like to give their children soft food, it is easy to chew, so that the functions of teeth and jaws can not be exercised. Over time, the chewing function will decline, the mandible will be stunted, the gums will not be full, and the teeth will be irregularly arranged. Therefore, it is necessary to let children eat more hard food and teach them to do dozens of frequent biting exercises every day to promote the occlusal ability of teeth.
Bad living habits can also cause children's dentofacial deformities. For example, during artificial breastfeeding, due to factors such as baby posture, bottle position and incorrect opening of artificial nipple, mandibular protrusion or retraction may be formed. Let the baby hold the bottle and lie flat on the bed to suck milk. The wine bottle is pressed on the upper skull and nose tip, and the lower lip and mandible are stretched forward excessively, which will easily lead to "heaven covering the ground". Therefore, when breastfeeding artificially, it is appropriate for the baby to sit in a semi-sitting position. At the same time, pay attention to the position of the bottle and the flow direction of the milk, and don't oppress the upper jaw or lower jaw excessively.
According to observation, nearly 75% of 3-4 month-old babies suck their fingers, which is a habitual action. Children suck their fingers, which are inserted between the upper and lower front teeth from bottom to top, causing the upper front teeth to protrude, the lower front teeth to retract, and the teeth to be crowded and irregular. Of course, the habit of sucking fingers will gradually decrease or disappear after the age of 2. If this action continues after the age of 2, it will cause obvious dentofacial deformity. The formation of this habit is often related to the change of living environment and some diseases. If you are weaned suddenly during lactation, your appetite can't be satisfied, because your clothes can't move freely, or you are bored because you don't have suitable toys, you can develop the habit of sucking your fingers. Therefore, in infancy, we should pay attention to observing the baby's emotions and common habits. In addition, pay attention to the baby's sleeping position. Don't always fix a position, so as to avoid long-term compression of one side of the maxillofacial region to form asymmetric developmental deformity of the maxillofacial region.
〈 4 〉 It is more important to prevent dentofacial deformities in early childhood. In addition to paying attention to reasonable diet, treating deciduous teeth caries in time and treating nasopharyngeal and systemic diseases as soon as possible, it is mainly to prevent the formation of bad habits to prevent the development of deformity. Several common bad habits in childhood are:
① Tongue-making habits can be divided into three types: tongue spitting, tongue licking and tongue sticking.
② Bite your lips, especially your lower lip.
③ Unilateral chewing habit means liking unilateral chewing.
④ School-age children often have the habit of biting pencils, rulers or triangles.
⑤ The habit of breathing with your mouth while sleeping.
6. Imitate the habit of others' chin stretching forward.
Children with bad habits, on the one hand, use psychological correction to persuade and educate them, remind them to pay attention at any time, and let them get rid of bad habits themselves; On the other hand, we should pay attention to improving the environment and diverting children's attention; If bad habits are overcome before 10 years old, most dentofacial deformities can disappear by themselves. Children who have formed dentofacial deformities should be corrected in time. /kloc-after 0/2 years old, the child lost his primary teeth and grew permanent teeth, and the dislocation was still obvious. Then they should go to the stomatological hospital, ask a specialist to correct their deformity and give orthodontics.
Generally speaking, the age from 12 to 15 is the best orthodontic age. At this time, the permanent teeth are more uniform, but not very strong. It is entirely possible to grow a pair of white and neat teeth by grasping the corrective treatment.
