Orthodontics of anterior teeth in nine-year-old children. Nine-year-old children's malocclusion, also known as malocclusion, is caused by congenital genetic factors or acquired environmental factors, such as disease, bad oral habits, abnormal tooth replacement and so on. If the anterior teeth are misaligned, it is suggested that the deciduous teeth fall off and the permanent teeth erupt before correction. Generally, correction is carried out after 12 years old, and it is easy to place fixed appliances. It is also a period of rapid growth of children, with rapid and agile tooth movement and ideal correction effect. Parents are advised to take their children to orthodontics, and the doctor will tell them the best treatment plan.
