The best age for orthodontic treatment differs for different malocclusions: 1, in the period of milk teeth, that is, 3-5 years old or 6-11 years old during the period of teeth, if the individual teeth are slightly wrong (teeth together), do not need immediate orthodontic treatment, you can observe or correct oral habits, because in this period, the teeth are in the time of growth and development, through the correction of bad habits, sometimes minor misalignment (teeth together) deformity is possible If the growth and development of the serious wrong (dentition), to be corrected in a timely manner, such as the milk teeth of the anti (dentition), will prevent the growth and development of the maxilla, affecting the jaw facial appearance, if the child with, at the age of 3-5 years can be corrected, such as a serious jaw recession, during the period of tooth replacement (dentition) should be corrected early to interrupt its development in a more serious direction; 2, the permanent incisor twist also Can be orthodontic treatment during the period of tooth replacement (dentition), most of the wrong (dentition) malformation to wait until the permanent period of tooth replacement, the age is 12-14 years old, when the permanent teeth root development is basically completed, the upper and lower teeth between the bite relationship is also adjusted to complete, can make a clear diagnosis of the type of wrong (dentition) malformation, and take the appropriate orthodontic treatment, correction is easy to maintain stable results after completion, will not occur After the orthodontic treatment is completed, it is easy to maintain stable results without too much change. Theoretically, the best age for orthodontic treatment is at the peak of growth and development of children, boys at 12-14 years old, girls at 11-13 years old, but each child’s growth and development and individual differences, can not be generalized, if you miss the period, to 15-17 years old is still in the adolescent period, growth and development is more active, although the difficulty increases, but the effect of orthodontic treatment is also better, if at the age of 18 After the age of 18 to adults, growth and development is basically completed, the effect of orthodontic treatment is not as good as in childhood and adolescence, but because there are serious bone malocclusion (malocclusion), but also can not simply use orthodontic methods to solve, such types, we must wait until after 18 years of age in adulthood, with surgery to treat.
