Located just a 2-minute walk from Tokyo Metro Higashi-Ikebukuro Station, directly connected to the Sunshine City underground passageway in Owl Tower B1, Tsubakimoto Dental Clinic practices dental treatment based on Minimum Intervention as advocated by the FDI World Dental Federation, under the philosophy of 'preserving teeth as much as possible' championed by the dean, a Doctor of Dental Science specializing in conservative dentistry and endodontics. The clinic's most distinctive feature is the presence of a root canal specialist on staff, who actively utilizes precision equipment such as dental CT and microscopes to provide objective diagnoses and high-precision endodontic treatment. The clinic offers a wide range of services including general cavity and periodontal treatment, wire and clear aligner orthodontics, dental implants, teeth whitening, and cosmetic dentistry, with consultations available from an orthodontic specialist certified by the Japanese Orthodontic Society. The clinic is characterized by its attentive care, including equipment designed to minimize pain, careful listening to patients' concerns, and explanations of technical terms in plain language. The clinic is open until 7 PM on weekdays and until 5 PM on Saturdays, and accepts credit cards and electronic payments.
