Tomioka Dental Clinic is conveniently located just a one-minute walk from Takadanobaba Station in the Takadanobaba area of Shinjuku Ward. One of the clinic's distinguishing features is its use of a dental microscope. This equipment enables precise observation of fine details that are difficult to see with the naked eye, allowing for more accurate diagnoses and meticulous care. The clinic is also a registered medical cooperation partner of Tokyo Medical and Dental University, the National Center for Global Health and Medicine, and the Tokyo Metropolitan Health and Medical Corporation Okubo Hospital, ensuring a well-established referral and coordination system for cases requiring specialized care, such as complex orthodontic treatments and difficult root canal therapies. The clinic director actively pursues academic activities, including lecturing at the Japanese Academy of Osseointegration and attending meetings of the European Federation of Periodontology, ensuring care informed by the latest advances in dental medicine. Weekday evening hours extend until 8:00 PM, making it convenient for patients visiting after work. Saturday hours are available in the morning only. Appointments are generally required, though the clinic makes every effort to accommodate emergencies such as sudden pain as promptly as possible.
