What people usually refer to as uneven teeth, tiger teeth, enameled teeth, and bulbous teeth are medically called malocclusion, which is a common oral disease in children and adolescents. It is a common oral disease among children and teenagers. Malocclusion causes misalignment of teeth and makes oral cleaning difficult, which can easily lead to dental caries, gingivitis, periodontitis, etc. In serious cases, it can also lead to abnormal jaw and facial growth and development and temporomandibular joint diseases, affecting chewing function and digestion and absorption, which is harmful to children’s growth and development and health. Therefore, parents should pay attention to their children’s orthodontic problems, and grasp the best age for orthodontics. The best time for orthodontics in children is divided into the functional orthodontic period (6-12 years old) and the fixed orthodontic period (12-18 years old). In other words, if a child has dental malocclusions such as anterior retrusion, functional recession of the lower jaw that may affect jaw development and bite relationship, they need to be corrected in time at the age of 6-12 or even earlier, if they wait until their upper and lower jaws are set in development to correct their teeth, it will be very difficult and will not solve the uncoordinated facial shape. If your child is just having misaligned teeth, you can wait until after the age of 12 to straighten them. Remind parents: must take their children to the regular hospital to receive regular treatment, because the good orthodontic depends mainly on the doctor’s skills, and there is a degree of irreversibility, once the orthodontic failure, the success of the treatment again is very difficult. Of course, patients should also take the initiative to cooperate with the doctor to express their plastic needs in detail, so that the doctor to design a targeted orthodontic program, do not want to go to the cheap to find a doctor who has not formally studied orthodontic technology treatment, so as not to miss the opportunity to regret their lives.
