Located in Funabashi, Setagaya Ward, Tokyo, Hasunuma Dental Clinic is a dental practice rooted in the local community. Director Keiji Hasunuma also serves as the school dentist at the local Yahata-yama Elementary School, establishing a treatment system capable of accommodating patients across a wide age range. A distinctive feature of the clinic's treatment philosophy is its commitment to preserving natural teeth. Rather than replacing teeth with artificial alternatives, the clinic prioritizes root canal treatment to save patients' own teeth, creating an environment where treatment options are chosen after careful explanation of what is best for each patient. Additionally, the clinic provides visual explanations using X-rays and intraoral photos at the dental chair, while also working to reduce patient burden through laser treatments for inflammation relief, pain management, and hemostasis. For dentures, multiple options are available, including those with minimal foreign body sensation and those with excellent stability. In terms of hygiene management, the clinic implements thorough infection control measures using handpiece-specific sterilizers, highest-standard autoclaves, ultrasonic cleaners, and sterilization packs, ensuring treatment in a clean environment. In 2013, the clinic's equipment was completely renewed, demonstrating a proactive approach to introducing the latest technology. Consultation hours cover mornings and afternoons on weekdays and Saturdays, with credit card and electronic payment options available, as well as parking facilities.
