Located just a 2-minute walk from JR and Tokyo Metro Ogikubo Station, Yamaguchi Dental & Orthodontic Clinic is a community-rooted dental practice that has served the Ogikubo area for three generations. Now led by third-generation director Masafumi Yamaguchi, the clinic was renewed and expanded to offer a broader range of dental services. In addition to general dentistry, pediatric dentistry, periodontal treatment, and preventive care, the clinic provides orthodontics, implants, oral surgery, cosmetic dentistry, and whitening — all under one roof. A notable strength is its orthodontic care, handled by the vice director, who holds specialist and instructor certifications from the Japanese Orthodontic Society and has taught orthodontics as a university professor, bringing a high level of expertise to even complex cases. The clinic is equipped with a dental CT, cephalometric imaging, and a European-standard Class B sterilizer, ensuring both precise diagnostics and rigorous infection control. It also invests in patient safety and comfort with EMS Airflow precision cleaning, an extraoral vacuum, and a surgical-room air purification unit. The waiting area features a kids' space with a monitoring camera, making it convenient for families with young children. Credit cards, electronic payments, and barrier-free access are all supported, reflecting the clinic's commitment to accommodating diverse patient needs.
