The human tooth is divided into two main parts: 1) the crown, which is exposed in the mouth (i.e., the tooth visible in the mouth), and 2) the root, which grows in the toothbed. The root of a normal tooth is completely buried in the alveolar bone and is therefore very strong. When the alveolar bone around the root gradually resorbs for some reason (such as long-term periodontal disease), the tooth will begin to loosen. This loosening is pathological. The more the alveolar bone is absorbed, the more the tooth loosens; when the alveolar bone is completely absorbed, the tooth is lost. During the orthodontic process, the periodontium, alveolar bone and other structures will also undergo corresponding alterations. Some patients may experience mild loosening of teeth, soreness and discomfort, and weakness in chewing, which are all normal reactions during the treatment process. After the orthodontic treatment is completed, these phenomena will disappear and the teeth will return to normal. Everything is divided into two, especially in the medical field, the cure may produce some side effects, such as side effects of medication, surgery leaving scars, etc. In comparison, the side effects of orthodontic treatment are very mild, while its treatment effect is remarkable. What are the effects of orthodontic treatment? 1, the impact on the pulp 2, the impact on the root 3, the impact on the alveolar bone 4, the teeth become loose In short, to do orthodontic treatment both to achieve the treatment effect, but also to make the movement of the teeth as close to the physiological state, which is the reason for the longer course of orthodontic treatment, but this is good for the health of oral tissue. In addition to remind you that orthodontic treatment must be carried out by orthodontic specialists, rashly accept the correction of non-professional physicians, may bring unexpected consequences, in this million side is a lot of heavy lessons.
