The region is outside the capital area.
I got clear aligner orthodontic treatment at a dental clinic close to home. My lower jaw was in fairly good alignment, and I started treatment because my upper teeth were buck teeth.
Now it has mostly come into alignment. The cost was 3.8 million KRW, including the clear aligners and the monthly treatment fees. Rather than a dramatic effect, my impression has become much more refined and softer.
I recommend dental orthodontic treatment before double-jaw surgery.
