Kawashima Dental Clinic, located in Shimorenjaku, Mitaka City, Tokyo, offers dental care with a focus on preventive dentistry. The clinic's most distinctive feature is the presence of multiple veteran dental hygienists with over 10 years of service, who approach their work with a sense of awareness and responsibility as lifelong preventive partners. Drawing on this expertise, the clinic also places special emphasis on preventive dentistry for mothers and children. Based on the understanding that pregnancy often increases the risk of cavities and gum disease, and the philosophy that protecting a child's healthy teeth requires thorough oral care by parents themselves, the clinic provides support to help parents and children achieve healthy teeth together. The clinic accommodates English speakers and has a parking lot. The clinic is closed on Thursdays, Sundays, and holidays.
