I'm not particularly familiar with the doctors in that hospital, but orthodontics belongs to post-graduation education, and I don't introduce orthodontic treatment knowledge in detail at the undergraduate stage. So the doctor you choose should try to choose one who has studied orthodontics.

Quite what you explained, the complexity is not great, and the abnormal charging standards vary from place to place. In Nanjing, the treatment fee is 12000 yuan.

I wish you a beautiful and healthy tooth.
