Kawaguchi Dental Clinic, located on the second floor of Shinjuku Island Tower in the commercial heart of the Shinjuku and Nishi-Shinjuku area, has been serving as a community dental home since its opening in 1995, offering a wide range of dental care. Directly connected from Nishi-Shinjuku Station to Island Tower, the clinic has long been trusted by office workers and local residents alike. Its services span general dentistry, preventive care, periodontal treatment, dental implants, and wisdom tooth extraction, covering a broad spectrum of dental needs. Guided by the principle that healthcare is a collaboration between doctor and patient, the clinic dedicates ample time to explaining symptoms and treatment plans, ensuring patients can proceed with confidence. It also places strong emphasis on post-treatment maintenance, providing ongoing care rather than treating symptoms in isolation, and welcomes second-opinion consultations or inquiries from patients whose visits have lapsed. Hours extend until 9 PM on weekdays, with regular Saturday and Sunday sessions, making it easy to fit appointments into a busy schedule. The clinic is well equipped for convenience, accepting credit cards and electronic payments and offering on-site parking.
