Kasai Dental Clinic is a dental clinic located a 5-minute walk from the south exit of Futamata-gawa Station in Asahi Ward, Yokohama City, equipped with English support and parking. The clinic's treatment policy includes pain reduction through two-stage anesthesia, minimizing tooth removal, preserving dental nerves, and avoiding tooth extraction. The clinic offers a wide range of treatments including cavity treatment, periodontal treatment, root canal treatment, implants, dentures, cosmetic dentistry, whitening, and PMTC, as well as bad breath treatment, hypersensitivity treatment, and wisdom tooth management. Given the high aging rate in the area, the clinic focuses on periodontal treatment, root canal treatment, implants, and denture treatment to enable patients to eat with their own teeth for "90 years of life." The clinic emphasizes the importance of regular oral care while noting the view that periodontal bacteria are associated with systemic diseases such as diabetes, heart disease, and stroke. Appointments are completely required, with Saturday hours until 5 PM, and the clinic is closed on Sundays, Thursdays, and holidays. The clinic respects patients' time and operates with minimal waiting time and billing wait time.
