Located on the 4th floor of Shinjuku Mitsui Building, Shinjuku Nishiguchi Dental Clinic is a comprehensive dental clinic situated in a prime location just a 6-minute walk from JR Shinjuku Station and 30 seconds from Tochomae Station on the Toei Oedo Line. A major feature of this clinic is the complete installation of nine dental microscopes across all treatment rooms. While the adoption rate of microscopes in Japan is approximately 10%, this clinic has equipped all rooms with these devices, utilizing them not only for cavity and root canal treatments but also for dental hygienist cleanings, achieving precise and minimally invasive care. Additionally, the clinic actively incorporates advanced digital equipment such as dental CT, intraoral scanners (iTero), and the 3D navigation system "X-Guide," working to improve the precision of implant treatment and make treatment contents more visible to patients. The dental team includes specialists from national university dental faculties including Tokyo Medical and Dental University, Tohoku University, and Nagasaki University, with multiple qualified professionals in various specialized fields covering periodontal treatment, orthodontics, implants, and oral surgery. The clinic offers weekend appointments, treatment in completely private rooms, acceptance of credit cards and electronic payments, and barrier-free facilities, creating an environment that accommodates the diverse needs of patients.
