Located in Seishin, Chuo Ward, Sagamihara City, Kanagawa Prefecture, Sagamihara Keiyukai Dental Clinic is a large dental facility with a total floor area of 300 tsubo, providing comprehensive dental care ranging from pediatric and general dentistry to non-extraction orthodontics and dental implants. In terms of treatment, the clinic uses microscopes for all procedures and does not perform treatments with the naked eye, with no additional costs. For root canal treatments under insurance coverage, the clinic adopts the vertical compaction technique used by US specialists, which provides better outcomes than the lateral compaction method common in Japan. For orthodontic treatments, the use of a new material called rubber metal allows many cases to be treated without extracting premolars. Pediatric dentistry also utilizes precise microscope-based treatment, with procedures recorded and shown to parents, and a rubber dam mask is used to prevent moisture, ensuring no remaining decayed areas. Regular checkups contribute to cavity and gum disease prevention, early detection of oral cancer, and reduced risk of aspiration pneumonia. The clinic has English-speaking staff, accepts credit cards and electronic payments, and offers parking and barrier-free access.
