Located in Hakodate, Hokkaido, Seito Dental Clinic is a dental clinic that has provided community-based care for over 50 years since opening in 1966. The director, who earned a PhD in Dentistry from the Nihon University Graduate School of Dentistry and served as a part-time lecturer at Hokkaido University School of Dentistry, offers a wide range of treatments including caries treatment, periodontal treatment, pediatric dentistry, orthodontics, aesthetic dentistry, whitening, dentures, and implants. The clinic's treatment philosophy follows a systematic approach that progresses from establishing oral hygiene to improving occlusion and restoring natural health and beauty. The clinic is known for its progressive approach to preventive dentistry, emphasizing "minimal tooth reduction" and "preserving dental nerves" long before preventive dentistry became widespread. The clinic is equipped with private treatment rooms, consultation rooms where patients can speak one-on-one with doctors, and a dedicated training room for myofunctional therapy (MFT). By introducing the high-performance sterilizer "Lisa," which meets international standards (EN13060), the clinic achieves thorough hygiene management including instrument interiors. The clinic provides English support and has a parking lot for eight vehicles, making it accessible from a wide area. Many families visit across generations, and the clinic is long-supported by a wide range of ages as a community dental clinic.
