I recommend Seoul Gomaun Dental Clinic in Ssangmun-dong.

I highly recommend Seoul Gomaun Dental Clinic, located in Ssangmun-dong, Dobong-gu. Three directors specializing in integrated dentistry, orthodontics, and conservative dentistry collaborate to provide comprehensive care. They promise to minimize unnecessary tooth removal to preserve natural teeth, so I can receive treatment without worrying about overtreatment. Everyone, from the desk staff to the dental hygienists and the dentist, was so kind and attentive. They provided thorough and detailed explanations, making it easy for even someone like me, who has a severe fear of dental procedures, to receive excellent treatment. All appointments are by appointment only, so as long as you arrive on time, you can be seen right away without waiting. The clinic is closed on Sundays and public holidays, but is open weekdays from 9:30 AM to 6:30 PM. I recommend making an appointment in advance.
