[Orthodontics] Correction of non-extracted teeth

First of all, it was my first orthodontic treatment. I corrected it in a strange way that children do, and I couldn't see any improvement. Seriously, there is absolutely no communication with the director here. Every time I do something, he gets angry at the patient and screams at me. I'm not worried about the pain every time I go to the dentist, but my heart is pounding because I'm afraid of the director himself. The price is so expensive that I ended up having to go somewhere else to get it recalibratedㅡㅡ It was my money and my timeㅡㅡ
