Generally speaking, after you decide to do orthodontics, you should go to the orthodontics department of the hospital for consultation and examination before orthodontics. When you see a doctor for the first time, the doctor will have a preliminary understanding of your teeth through conversation and ask you the expected effect of orthodontics you want to achieve. I will initially communicate with you about your correction plan, so as to determine whether you want to have your teeth pulled out for correction. How many teeth have you pulled out? And the cost, duration and course of treatment.
