3-year review of tooth extraction orthodontic treatment

I had my protruding mouth corrected at the ㅅㅇㅌㄹㅇㅅ dental clinic located in Seomyeon, Busan . They said it wasn't a common case, so at first I did non-extraction for about 2 years and then another year after tooth extraction, but the director here looked at me from the beginning and the end , and the dental hygienist did everything... Also, I have a deep bite, so my corrector often broke, and the corrector broke again. I went there and found that my front teeth were wide open... They asked me for 1 million won to have them re-corrected... so I just put the braces back on.
