I suggest you go to Nanjing to have your teeth straightened. After all, compared with other hospitals, hospitals in Nanjing are well-equipped, experienced and guaranteed. And you go to school in Nanjing, so it's more convenient to correct your teeth on the spot. Visit again once a month, because the doctor has to change the elastic band of the appliance and keep the tension of the appliance unchanged, so as to achieve the correction effect. The rubber band plays the role of pulling back and repairing, and the iron wire embedded in the braces plays the role of fixing the position of teeth in the direction of orthodontics and will not be easily broken. I hope the landlord will adopt my suggestion. . .
