It’s common to see parents bring their 8 or 9 year old children in with anomalies, commonly known as pockets of teeth. Many of these children are caused by bad habits during the period of milk teeth, such as lying down to eat bottles, eating spoons, biting fingers, etc. Most of the parents do not have enough knowledge about milk teeth antalignment and do not bring their children to the clinic in time, thus delaying the optimal orthodontic treatment time. Orthodontic treatment during the period of milk teeth, to remove the anticlinal, correct the relationship between upper and lower jaws, for the normal eruption of permanent teeth, the normal development of jawbone has great benefits. The optimal age for orthodontic treatment of baby teeth is usually 3 ½ to 4 ½ years old. This is because the milk teeth come out at the age of 2.5 years, and the roots of the teeth take 1 to 2 years to develop completely. Early orthodontic treatment will not be conducive to the development of the roots of the milk teeth. After the age of 5, due to the alternation of milk and permanent teeth, the roots of the front teeth begin to be absorbed by the permanent teeth, and the treatment of anastomosis at this time will accelerate the absorption of the roots of the milk teeth, resulting in the early loss of milk teeth. At the age of 3 and a half to 4 and a half years old, the roots of the milk teeth have completely grown up, and at the same time, there is still a long time to the tooth replacement, which is the best time for correction. There are several kinds of orthodontic methods to correct the antomandibularity of milk teeth: 1, bite the tongue depressor: If it is a mild antomandibularity of the front teeth, you can put the tongue depressor or ice-cream stick between the upper and lower teeth, and bite it 2-3 times a day, each time biting 100 times or so, which has a very good effect. 2, movable orthodontic appliances: generally for the patient to make a plastic orthodontic appliances, wear on the maxillary teeth, rely on the strength of the wire will slowly straighten the anticlinal teeth. This method is more commonly used in the clinic, but there are the disadvantages of difficult fixation, large foreign body sensation, and the need for a high degree of patient cooperation. This may be the biggest disadvantage for the patients who are still young during the period of milk teeth, so the patients’ parents need to strictly supervise them, and if the patients can’t wear the orthodontic appliance according to the doctor’s instruction, it won’t produce any effect. 3.Fixed orthodontic appliance: Because the movable orthodontic appliance has the disadvantage of difficult fixation and patients are not willing to wear it, so fixed orthodontic treatment can be used to treat the anti-collision characterized by fast anti-collision correction, generally half a month to two months anti-collision can be lifted, and the later stage of orthodontic treatment is mainly to do some consolidation of therapeutic effect and prevention of recurrence, so the patient’s discomfort mainly occurs in the early stage of orthodontic treatment. Because of the small size of the orthodontic treatment, the children can easily adapt to it and like to wear it. Some parents worry that such a small child will not be able to tolerate the discomfort of basket dentistry, which is actually a misunderstanding. Discomfort increases with age, and the older the child, the greater the discomfort, which is why adult baskets can be more painful than those for children. At the same time, due to the shorter orthodontic treatment time, usually around six months, it will not affect the growth and development of your child’s teeth and jawbone.
