Located in Koishikaya, Ageo City, Saitama Prefecture, Ageo Happiness Dental Clinic & Pediatric Dentistry, which opened in June 2021, is a facility specializing in preventive dental care. The director, after obtaining a dental license and gaining experience as a director at one of Japan's leading preventive dental clinics and studying preventive dentistry in Sweden, has introduced world-standard systems. All treatment rooms are completely private, ensuring privacy, and a hygienic environment is maintained to prevent droplet transmission and infection. A dedicated dental hygienist supports patients' health, adopting the same system as advanced Western countries. The facility features a barrier-free design throughout, allowing stroller access, and restrooms are equipped with diaper changing tables. Credit cards and electronic payments are accepted, and parking is available. The clinic implements infection prevention measures, including COVID-19 precautions, such as instrument sterilization and the use of disposables. For initial visits, examinations take approximately 60 to 90 minutes, including an orientation, so it is recommended to arrive about 15 minutes before the appointment time.
