There are no noticeable disadvantages after the period of orthodontics when stability is reached, and overall there may be some degree of shortening of the roots of the teeth before and after orthodontics, but the magnitude is so small that it is basically negligible. The main disadvantage of orthodontics is that gingivitis, periodontal problems, and loose teeth, or even loss of teeth, can occur during the orthodontic process. Because the stimulation of orthodontics and the impact of tooth movement during orthodontics can cause periodontal problems resulting in gum recession and alveolar bone resorption, it is required to maintain good periodontal hygiene in the process of orthodontics. A systematic cleaning before orthodontic treatment and the application of a professional toothbrush for daily tooth cleaning during orthodontic treatment can relatively minimize periodontal problems during orthodontic treatment.
