First, individual tooth dislocations in deciduous teeth (especially between 2.5 and 6 years old) do not need to be corrected. However, if the child has bad tooth injury habits during this period, leading to tooth dislocation, it is necessary to actively treat it. Children's bad habits such as biting pencils, biting their lips, licking their teeth and breathing through their mouths should all attract parents' attention and be treated as soon as possible, otherwise it will easily lead to deformities such as teeth and jaws. If there is a "ground covering day" during the defoliation period, parents should be vigilant and must correct it as soon as possible. Otherwise, it will affect the normal development of maxilla and mandible and lead to facial deformity. During this period, many parents were misled by non-professional dentists, which delayed their children's timely correction.
Second, there is slight tooth irregularity during tooth replacement (6 ~ 12 years old), so you can observe it regularly and don't have to rush to correct your teeth. However, if abnormal skeletal development occurs, such as maxillary protrusion (upper teeth protruding outwards) or upper teeth covering lower teeth excessively, it should be corrected immediately. Early restriction of jaw dysplasia can not only simplify the correction in the future, shorten the course of treatment, but also give children a beautiful face. In addition, a series of tooth extraction is needed to correct the serious crowding of dentition when it is replaced.
Thirdly, after the replacement of deciduous teeth (12~ 18 years old) is the best time to correct tooth deformity. At present, the time of comprehensive treatment of tooth deformity with fixed appliance is generally short, and the treatment effect is ideal. Children of this age are still in primary school, and they go to the orthodontics clinic once a month, so they don't delay their studies. Parents should seize this period to give their children orthodontics in time, which saves time and money, and both parents and children benefit.
