Cosmos Dental Clinic, located in Kami-Meguro, Meguro Ward, Tokyo, is an English-speaking dental clinic equipped with parking and barrier-free facilities. Orthodontic treatment is provided by a certified orthodontist from Tokyo Medical and Dental University, offering free consultation days three times a month to address patient inquiries. This medical facility operates on an appointment basis, with consultations conducted in 30-minute slots. Patients arriving late may face changes in treatment content or denial of treatment on the day, so punctuality is important. Thursdays are currently closed indefinitely, and some days have early closing times, so advance confirmation is required when seeking treatment. For infection prevention, hand sanitizer sprays and droplet prevention panels are installed at reception, basic sets are individually packaged and sterilized. Dental instruments are packaged in sterilization bags and sterilized using high-pressure steam sterilizers and high-temperature oil sterilizers, while extraoral vacuums are used for aerosol-generating treatments. Doctors and staff wear goggles or face shields during treatment. Treatment fees covered by insurance are cash-only, while credit cards are accepted for non-insurance treatments. Time is set aside to listen directly to first-time patients, and the appointment-based system minimizes waiting times.
