Located in Hanagawagawa, Oita City, Sonogi Dental Clinic provides comprehensive dental care ranging from cavity and periodontal disease treatment to preventive care. Dr. Shinya Sonogi, the clinic director, graduated from Fukuoka Dental University and gained clinical experience in the Department of Periodontology at the university's medical and dental hospital before opening the clinic in 2021. The clinic places strong emphasis on post-treatment prevention, supporting patients with oral health management tailored to their lifestyles so they can enjoy meals with their natural teeth throughout their lives. The treatment rooms are equipped with intraoral cameras and large monitors displaying X-ray images, practicing "visible treatment" that allows patients to visually understand their oral conditions. The clinic also maintains strict hygiene standards, featuring world-class Class B sterilizers and medical washing machines, as well as the "Poseidon" dental unit waterline disinfection system to keep treatment water sanitary. The facility is barrier-free designed, accommodating visitors with strollers and wheelchairs. With nine parking spaces and Saturday hours available, the clinic is accessible for patients who have difficulty visiting on weekdays. English-speaking service is available, and the clinic serves a wide range of age groups in the community.
