Hello! Because everyone's degree of tooth deformity is different, the difficulty of correcting teeth is different, so the cost of orthodontics is also very different. Orthodontics includes examination, X-ray, design, tooth separation, bracket attachment, and some may need tooth extraction. Adult orthodontics generally takes about one and a half to two years, and a follow-up visit is needed during orthodontics, so how much it costs to do orthodontics is also very different. You'd better go to the local hospital when you have time. Usually between 1w-3w, the specific price is subject to the hospital charges.
