Dental Nakahashi, located in Yayoi-cho, Nakano Ward, is a registered oral function management-enhanced dental clinic with the Ministry of Health, Labour and Welfare, offering insurance-covered preventive dentistry and fluoride applications on a monthly basis. The clinic actively contributes to community healthcare by conducting annual on-site check-ups twice a year at nearby nursery schools and Meiji University Nakano Junior & Senior High School, providing dental examinations, professional health management guidance, and advice on emergency procedures. Infection prevention is a particular focus, with a system that distributes electrolyzed hypochlorous acid water (produced by electrolyzing high-purity salt and ultrapure water) throughout the clinic's piping, enabling sterilization inside the oral cavity including during treatment for water from treatment turbines and gargling. Treatment instruments such as turbines for drill pieces are all sterilized using autoclaves (high-pressure steam sterilizers), and disposable items like paper cups, aprons, and trays are used to reduce the risk of nosocomial infections. Emphasizing preventive dental care, experienced full-time dental hygienists provide preventive counseling to recommend oral health maintenance plans tailored to patients' lifestyles. English services are available, and the clinic accepts credit cards, debit cards, and electronic payments, allowing patients to receive treatment that meets various needs.
