With the improvement of people’s living standards, more and more patients are requesting orthodontic treatment, and inevitably many parents and friends are asking, “When is the best time to start orthodontic treatment for children?” Uneven teeth will not only affect the appearance of the child’s mouth, but also bring a heavy burden to the child’s mind, and may even produce a strong sense of inferiority and psychological barriers, affecting the development of the child’s physical and mental health. The director of orthodontics at Zhongshan Second Hospital, Chang Shaohai, reminded parents not to miss the “golden age” of orthodontic treatment for children and adolescents. The best age for orthodontic treatment, depending on the wrong type of child’s teeth, is generally divided into three stages: First, the period of milk teeth stage (4-5 years old) This period is mainly applicable to the milk teeth anti (enamel), early orthodontic treatment is conducive to the development of the upper jaw bone, the prevention of permanent teeth anti. If the child has bad habits (such as tongue extension, lip biting, etc.), they can also be corrected at this stage to prevent the occurrence of errors. The early stage of the teething phase (girls: 8-10 years old, boys: 9-12 years old) is suitable for functional and bony errors caused by bad habits, tongue interference, and other factors. If you find that your child has bad habits (such as lip biting, tongue extension, forward jaw extension, etc.), abnormal facial shape and abnormal tooth alignment during the teething stage, you should promptly take your child to the hospital for examination and consultation with an orthodontic specialist. If your child has a functional or bony malocclusion, treatment at this stage can make full use of the growth potential of the jaws and achieve the purpose of treatment by promoting or inhibiting the growth of the jaws, which is more beneficial to improving the child’s facial shape and function. Early permanent teeth stage (girls: 11-14 years old, boys: 13-16 years old) The common malocclusions can be treated well at this stage. At this time, most of the permanent teeth in the mouth have erupted, the development of the dental arch has been basically completed, and the misalignment of the teeth has been basically set; and this age of the child’s jaw facial development is still in the rapid period of growth and development, orthodontics to a large extent need to use the jaw facial growth and development potential, so that tooth movement and alveolar reconstruction to achieve the best level. If you miss the “golden age” of orthodontics and enter adulthood, you will need orthognathic surgical treatment to achieve the desired effect for severe jaw and bone relationship abnormalities, such as a family history of “severe anterior dentition”. In addition, for adults after treatment relapse, is also a major problem for doctors, generally speaking the longer the correction and maintenance, the better the stability. Generally speaking, adults with malocclusion can achieve the desired results as long as they are properly treated and maintained in a stable manner. The “one-week orthodontic treatment” or “fast orthodontic treatment” that has been hotly debated in society in recent years has formed a misconception about orthodontic treatment. The so-called “one-week orthodontic treatment” or “fast orthodontic treatment” is actually a restorative method to change the front teeth. The movement of teeth is a physiological change process, which mainly conforms to the human body’s physiological changes without causing lesions, the whole foot process is the periodontal tissue, bone tissue reconstruction process, need to be completed in the appropriate time, so the world’s orthodontists believe: 1-2 years of orthodontic time is appropriate and will not cause adverse reactions. Like a moving train, a single-minded pursuit of speed may cost lives. We also hope that parents do not make their children pay the price for the rest of their lives for the sake of momentary convenience, and that consulting a regular hospital or clinic for treatment is a wise choice. Therefore, determining the best time for orthodontic treatment is not absolute and doctors depend on the different types of malocclusion and the growth and development of the individual. However, for many patients with facial deformities caused by teeth, timely access to treatment can receive twice the result with half the effort.
