Oto Dental Clinic, located in Kitayoshizu-cho, Fukuyama City, Hiroshima Prefecture, is a nationally rare dental practice that has specialized in conservative treatment for over 30 years. Under the philosophy of 'preserving teeth as much as possible without extraction or unnecessary drilling,' the clinic prioritizes tooth preservation through occlusal improvement, periodontal treatment, and extraction-free orthodontics. A hallmark of the practice is its thorough informed consent approach: enlarged monitor displays are used to explain patients' oral conditions in detail, allowing patients to participate in choosing their own treatment plan. Even in cases where extraction becomes unavoidable, customized treatment is provided only after thorough explanation and discussion, reflecting a strong commitment to patient satisfaction. The facility maintains rigorous infection control and medical safety standards, including an installed AED and an established emergency transfer network with partner hospitals. English-speaking staff are available, and the clinic is equipped with parking facilities and barrier-free access, making it accessible to patients in a wide range of circumstances. Consultations are scheduled on weekday and Saturday mornings and afternoons, and the clinic has long been a trusted pillar of dental care in the local community.
