1. Why are more and more children having misaligned teeth? There are genetic and human evolutionary factors that are difficult to control when children’s teeth are not aligned. However, uneven teeth are more related to whether children pay attention to oral hygiene, whether they have bad oral habits and other lifestyle habits, which are controllable factors. If you want to have beautiful teeth, you should change bad habits, such as biting fingers, biting lips, spitting and biting the tongue, and also eat more coarse fiber foods and hard foods. For example, bones and sugar cane, so that the alveolar bone is dense and the gums are strong. In addition, prevention of decay of milk teeth and regular oral examination are also important ways to prevent malocclusion. 2. Why do the baby teeth grow neatly but the permanent teeth are messy? The more neatly arranged the baby teeth are, the more likely the permanent teeth will be disordered after tooth replacement. This is because the permanent teeth are bigger than the baby teeth, and the space and bones in the mouth are limited, so the permanent teeth will naturally cause the teeth to be misaligned because of the limited space to grow and squeeze each other. Let’s say a bench that can sit 12 people is filled with 14 people, someone is bound to move forward or backward, or even to stand up. In general, 24 teeth are enough for people, so extra teeth will have an adverse effect, which is why some patients need to have their teeth extracted before wearing braces. 3. When is the best time to wear braces? Children with serious malocclusion, such as “big chin”, “small chin” and “pocket tooth”, should start treatment before tooth replacement, otherwise it will affect the normal development of jaw bone and may lead to abnormal jaw bone development. Otherwise, it will affect the normal development of the jaws and may lead to abnormal development of the jaws, and individual patients even need orthodontic-orthognathic treatment. If the malocclusion is slightly light, it is recommended to start wearing braces when the child is about 12 years old, i.e. after the teeth have been replaced. The child at this age has a good metabolism, and the movement of the teeth after wearing braces will carry the bones to move, which will help to change the face shape and the normal development of the bones. 4.Will orthodontics loosen my child’s teeth? Orthodontic technology has been around for more than 100 years, and the pattern is the same all over the world. There is no problem as long as you seek treatment from a professional orthodontist. Some part-time orthodontists claim to be able to complete orthodontics and remove braces within a year, which is actually unscientific: teeth moving too fast can be harmful, and in addition to aligning teeth, facial shape and health issues should also be considered. 5.Will orthodontics affect my child’s daily study and life? Orthodontic treatment only requires a monthly follow-up, and some hospitals also set up night clinics and weekend visits, basically will not affect the child’s school. After wearing braces, children can avoid bleeding gums and tooth decay as long as they have regular follow-up appointments and brush and clean their braces properly. Wearing braces does not affect the appetite. For about 3 days to 1 week after wearing braces, there will be slight discomfort or pain in the teeth, especially during meals, which is normal and will not be affected afterwards. 6, after the best orthodontic time is not orthodontic? As we grow older, orthodontics will take relatively longer, but it does not mean that adults can not braces. Adults can receive orthodontic treatment as long as the periodontal and oral hygiene health is good, and can receive satisfactory orthodontic results, “whether orthodontics and the size of the age of the relationship is not much, but rather with the health of the periodontium. Patients with serious periodontal disease and very loose teeth are recommended to do treatment to retain teeth before braces. Similarly, patients with cavities and gum inflammation should be treated before braces,” Dr. Chen added. But adult orthodontics also needs to be done as early as possible and not to miss the orthodontic age again and again. Because as we age, the receding gums, crowding and convexity of the teeth will slowly increase.
