Seijo Dental Clinic is located in Seijo, Setagaya Ward, Tokyo, approximately a 5-minute walk from the south exit of Seijogakuen-mae Station on the Odakyu Line. The clinic's most distinctive feature is its "interdisciplinary approach," where multiple dentists collaborate by leveraging their respective areas of expertise. The director, who is also a certified periodontal specialist, serves as the primary attending dentist and oversees all treatment, while specialists in precision root canal treatment, implant therapy, orthodontics, oral surgery, prosthodontics, and periodontal treatment work together to provide comprehensive care. The clinic is particularly skilled in handling difficult cases involving advanced periodontal disease, occlusal collapse, and complex combinations of dental issues, actively accepting patients who have been told their conditions are difficult to treat at other facilities. The clinic is equipped with 6 dental microscopes, CT imaging, intraoral scanners, CAD/CAM systems, and 3D printers, enabling highly precise diagnosis and treatment. Clinic hours are from 8:00 AM to 6:00 PM, with credit card and electronic payment options available, and parking is provided on-site.
