The best age of orthodontics for most patients is adolescence, which is different for men and women in rapid adolescence. Girls are a little earlier, about 1 1 years old to 13 years old, and boys are a little later, about 12 years old to 14 years old, but it is not completely limited to this time. Early treatment may be needed, while some patients may need late treatment, such as patients with large mandible and short maxilla, who advocate early interventional treatment. It is possible that the patient will be treated when he is 7 or 8 years old, and the effect may be better. However, if the adult patients who miss this age are in good health and their teeth are not loose, they can also undergo orthodontics. Shijiazhuang yongqi dentistry
