Located at 4-5-6 Honmachi, Okaya City, Nagano Prefecture, Ota Dental Clinic, operated by Shizenkai Medical Corporation, has been providing dental care to the community since 1960 for 65 years. The clinic upholds the philosophy of "treating without extraction," conducting treatments aimed at fundamental improvement of diseases without assuming tooth extraction. In treatments for cavities, periodontal disease, orthodontics, and more, they utilize the latest technologies while avoiding unnecessary tooth extraction.

To enable early detection of cavities and periodontal disease, they have introduced the 10-image dental photography method, and along with preventive dental treatment, they work to prevent symptom deterioration. In terms of equipment, they are equipped with advanced devices such as dental CT, microscopes, lasers, and photo-functionalization technology, realizing treatments that minimize nerve removal and tooth extraction. Furthermore, the clinic has a pediatric dentistry specialist certified by the Japanese Board of Pediatric Dentistry on staff, providing treatment that considers children's growth and development. They offer services in English, accept credit card and electronic payments, and have parking and barrier-free facilities available.
