I visited Yonsei U-Line Dental Clinic for cavity treatment, and it was an overall satisfactory experience. The wait time from registration to treatment was short, and the staff was friendly and helpful, allowing me to receive treatment in a comfortable atmosphere. The dentist showed me the condition of my cavity on a screen and explained the current progress and treatment method in detail, which made it easy to understand. He checked my pain during the treatment, which helped ease my anxiety, and I felt the dentist was thorough and attentive. The post-treatment instructions were detailed, making it easy to manage. I also felt confident that the dentist treated only the necessary areas without overtreatment.
