This is the most worrying issue for many patients and parents who wish to straighten their teeth, the answer is no, straightening teeth will not lead to premature tooth loss, on the contrary, it is favorable to the maintenance of teeth. First, uneven teeth easily lead to various dental diseases, common periodontal disease often lead to alveolar bone resorption, which is a kind of pathologic resorption, and in serious cases lead to tooth loss. Secondly, the force of orthodontic treatment is very small, the movement of teeth is a physiological movement, which will not lead to alveolar bone resorption and root resorption, and after a certain period of time after orthodontic treatment, the loose teeth become very strong again. Third, through orthodontic treatment aligns the teeth, restores the normal occlusion, and the periodontal tissues of the teeth are healthier, which not only improves the efficiency of mastication, but also reduces the incidence of dental diseases, and effectively prevents the teeth from loosening and falling off when people grow old. In addition, during the orthodontic process, the teeth will appear mild loosening, soreness and discomfort, chewing weakness, etc. These are normal reactions during the treatment process, do not have to worry about, after the end of orthodontic treatment, the teeth will gradually return to the normal state, and these phenomena will disappear.
