Nikaido Dental Clinic, located in Kamikawachi-machi, Kawachi District, Tochigi Prefecture, has provided dental care to the local community since 1984. With the motto "preserve teeth," the clinic emphasizes prevention of cavities and periodontal disease while striving to perform treatments that minimize tooth extraction and reduction. The director has specialized expertise in preventive dentistry, educating patients with accurate knowledge about cavities and periodontal disease and explaining effective prevention methods in an easy-to-understand manner. The clinic primarily offers general dentistry, focusing on early detection and treatment of cavities and periodontal disease, with extensive experience in denture fabrication and adjustment. Since periodontal disease increases the risk of systemic diseases such as diabetes, heart disease, and stroke, the clinic encourages early treatment initiation. The facility is barrier-free with a slope at the entrance, allowing smooth access to treatment rooms with strollers or wheelchairs. The treatment rooms are more spacious than usual and partially separated by partitions, creating a relaxing environment where patients can receive treatment with privacy. Additionally, a kids space is available, making it easy for those with small children to visit. The clinic director also serves as a school doctor at a large kindergarten, utilizing this experience in pediatric dental care. English service is available, and parking is provided. The clinic prioritizes informed consent, respecting patient preferences while valuing warm communication.
