I had orthodontic treatment at Harmony Dental Clinic.

I made my decision regarding orthodontic treatment after visiting several clinics recommended by an acquaintance. I visited Harmony Dental Clinic in Myeongil-dong, Yonsei Woori Dental Clinic in Jamsil, and Seoul EOS Orthodontics & Dental Clinic. Harmony Dental Clinic ranked first, Yonsei Woori Dental Clinic second, and Seoul EOS Orthodontics & Dental Clinic third. The reason for choosing the top spot is that, since orthodontic treatment requires frequent visits to the dentist, I selected a location close to my home.
