Yamakawa Rintaro Dental Clinic, located in Saijo City, Ehime Prefecture, is a dental clinic providing dental care. They offer precise treatments using magnifying glasses and microscopes, and by improving the fit of crowns, they work to make it less likely for cavities to develop at the boundaries between teeth and crowns. To reduce pain during treatment, they apply anesthesia to the gum surface before using thin needles, inject the anesthetic slowly, and take sufficient time before starting treatment. The clinic utilizes preservative-free anesthetic solutions and tailors anesthesia to individual treatment needs, minimizing post-treatment discomfort. In terms of facilities, digital X-rays enable smooth imaging, and treatment plans are carefully explained while viewing images on a chairside monitor. Private consultation rooms that consider privacy are also available. For oral care, licensed dental hygienists carefully remove tartar and provide personalized brushing guidance. The facility features barrier-free design from the entrance to the treatment rooms, and includes a spacious parking lot and a kids' space.
