飯田下伊那口腔衛生センター, located in Higashishinmachi, Iida City, Nagano Prefecture, is a facility operated as a "Holiday Emergency Dental Clinic" that supports local dental emergency care. A distinguishing feature of the center is that it does not offer treatment on weekdays or Saturdays, opening exclusively on Sundays, national holidays, during the Bon festival period, and the year-end/New Year period—times when general dental clinics are typically closed. Hours are from 9:00 AM to noon, serving as a safety net for sudden toothaches and oral problems that arise on holidays, and playing a vital role for residents of the Iida-Shimoina area. The facility is designed to be barrier-free, ensuring a comfortable environment for elderly visitors and those with physical disabilities. Ample parking is also available, making access by car easy during emergencies—an important convenience for a center that serves a broad geographic area. With a clear mission of handling dental emergencies that occur on holidays, this facility fulfills an essential public role by bridging gaps in community healthcare.
