When you find that your child’s teeth are misaligned, some parents think that all you have to do is go to an orthodontist for treatment, but that’s not entirely true. There is a specialty in orthodontics, namely orthodontics. Children in the growth period, the jaws and craniofacial structures where the teeth are located are constantly growing and changing, so orthodontics should also be a dynamic process, which requires orthodontists to have a comprehensive knowledge of dental, jaw, craniofacial growth and development, and must also have a considerable foundation in oral aesthetics. As different types of malocclusion, or even the same type of malocclusion, the pathogenesis of different patients is not the same, which determines its orthodontic methods, the timing of treatment intervention. For some malocclusions (such as crowding caused by tooth replacement disorder, malocclusion caused by bad habits), some simple treatments can be taken at an early stage to stop the occurrence and development of malocclusion in a very short period of time and achieve twice the result with half the effort. For example, some abnormal jaw development, there is still a lot of room for growth improvement in the early growth and development, early correction can make the child’s jaw and facial skeletal structure back to normal, to avoid the development of serious bone deformity later and must use surgical treatment. However, in some serious bony deformities (such as bony mandibular backbite with family history), the growth trend and severity are beyond the ability of orthodontic intervention, and it is difficult to correct them no matter what treatment is used in the early stage, and premature treatment can only prolong the treatment time, increase the cost and pain. It is worth noting that orthodontic treatment sometimes requires tooth extraction, so parents may want to consult an orthodontist first when a child has severe caries (tooth decay) with misaligned teeth. If orthodontic treatment does require tooth extraction, the orthodontist will choose to remove the unhealthy teeth first, so as to avoid excessive or unnecessary treatment of tooth decay. For example, if some teeth are missing due to trauma or caries, the orthodontist can replace the missing teeth with adjacent teeth through orthodontic treatment, thus avoiding the need for denture repair.
