Located on the second floor of Super Arcs Kikusui in Kikusui, Shiroishi-ku, Sapporo, Nishi Dental Clinic is a dental practice centered around preventive dentistry. The clinic's director has questioned conventional dental approaches of drilling, filling, and extracting, operating on the belief that creating an environment where teeth don't deteriorate in the first place is the true essence of dental care. A distinguishing feature of this clinic is that they provide patients with careful explanations of why cavities and gum disease developed, focusing not merely on temporary measures to alleviate pain but on addressing the underlying causes. With the conviction that nothing surpasses natural teeth, they aim to preserve as many teeth as possible, and actively educate patients about the impact of tooth loss on overall health—including links to heart disease, stroke, and dementia risks. From the perspective that establishing regular oral care habits contributes to long-term health maintenance and reducing medical costs, they offer lifestyle recommendations with a preventive focus. The clinic provides services in English, accepts credit cards and electronic payments, and has a parking lot. Closed days are Thursdays, holidays, year-end/New Year period, and Obon season.
