Todoroki Imai Dental Clinic, located in Todoroki, Setagaya-ku, Tokyo, is a dental practice built on four guiding principles: scientific evidence, advanced technical skill, thorough communication, and hospitality. A notable feature of this clinic is its use of precision medical equipment—such as microscopes, high-magnification loupes, and 3D CT scanners—in all treatments, equipment adopted by only about 6% of dental clinics in Japan. In dental care where micron-level precision is essential, the clinic has created an environment capable of addressing areas invisible to the naked eye. Rigorous infection control is another priority, with a Class B sterilization system and an automated instrument washing and disinfection system found in only about 5% of Japanese dental practices. Pain management is equally meticulous: by combining a pre-applied topical anesthetic, temperature-controlled anesthetic solution, ultra-fine needles, and computerized local anesthesia delivery, the clinic minimizes patient discomfort. Fully private treatment rooms and a dedicated counseling space ensure privacy while allowing personalized explanations and shared treatment planning. The clinic's philosophy is also reflected in its commitment to predictable, long-lasting care designed to minimize the need for retreatment, with a outlook of 20 to 30 years. Credit cards and electronic payments are accepted, and barrier-free facilities are available.
