Many people believe that adult orthodontics can no longer be performed over the age of 18. This statement is actually a misconception. Why do you say that? The reason is that the human alveolar bone is in a state of change throughout life, so there is no limit to orthodontic treatment at any age. However, since the repairing ability of alveolar bone of adults is lower than that of teenagers or children, the course of orthodontic treatment for adults is generally longer. At the same time, adults often have decayed teeth, bad teeth, missing teeth, broken teeth, periodontal disease and systemic diseases such as hepatitis, diabetes, etc., which will also bring certain difficulties to orthodontic treatment, the risk is relatively large, the cost is also relatively high, and the technical level of doctors is also put forward higher requirements. Therefore, when some adults go to some clinics or hospitals for consultation, they are told that adults cannot perform orthodontics, the reason is more due to the limited professional understanding and technical level of doctors. In addition, there are some people who think that doing adult orthodontics will make the teeth loose and fall off, and think that this view is also one-sided. If a professional doctor in a regular hospital will communicate deeply with the patient before orthodontic treatment, adopt a reasonable orthodontic treatment plan, and apply reasonable force during orthodontic treatment, not only will it not cause tooth loss, but also will delay the loss of teeth. The reason is that orthodontics can make the alignment and bite of the teeth more reasonable, and some periodontal diseases can be better prevented and controlled, which is more conducive to dental care.
