City Dental Clinic Roca, located near Roka Koen Station in Setagaya Ward, Tokyo, is a historic dental clinic established about 45 years ago by the founder, now operated by the second generation with a concept of "highly transparent dental care." The clinic emphasizes creating an environment where patients can receive treatment with full understanding by carefully explaining conditions before, during, and after procedures. They offer a comprehensive range of services including general cavity treatment, preventive dentistry, whitening, orthodontics, and implants, with a strong focus on preservation treatments that save natural teeth whenever possible. For specialized procedures such as oral surgery and root canal treatment, dentists from Tsurumi University Dental School Hospital provide care, and the clinic is equipped with advanced technology including oral scanners, dental CT, microscopes, and rubber dam isolation to ensure precise treatment and prevent recurrence. For children who feel anxious about dental treatment, they employ painless anesthesia techniques, aiming to be a family dentist serving three generations from children to the elderly. They are open on weekends and holidays in addition to weekdays, and accept credit cards and electronic payments.
