Hello, a private appointment is fine. It is suggested that children should wait until they are 12 and 13 years old. During this period, all the deciduous teeth have fallen off. Once the teeth are arranged irregularly, it is generally difficult to recover on their own. Orthodontics with braces has a better effect. Parents can take their children to the stomatology department of Children's Hospital. First take a dental examination, and then the doctor will make a reasonable treatment plan according to the deformity of the child's mouth. Then you need to wear braces, which usually takes about a year and a half. In the meantime, children also need to go to the hospital for follow-up visits regularly.
