Located on the B1 floor of Tokyo Nihonbashi Tower Annex in Nihonbashi, Chuo Ward, Tokyo, this dental clinic offers a wide range of treatment options, including basic treatments such as tooth decay treatment, periodontal disease treatment, and oral surgery, as well as aesthetic dentistry like teeth whitening, orthodontics, and preventive dentistry. The clinic's treatment philosophy prioritizes preserving teeth and nerves as much as possible, with a fundamental approach of not grinding down or extracting healthy teeth. The Sekikai Group operates 22 clinics primarily in Tokyo, and a system is in place where patients can receive treatment at different clinics using the same medical records. By thoroughly emphasizing preventive dentistry, the clinic takes an approach of maintaining and managing oral health before symptoms appear. Examination rooms are completely private, with consideration given so that sounds and voices during treatment are not audible to other patients. To address anxiety and pain associated with dental treatment, three methods have been introduced: applying surface anesthesia before anesthesia injections, using ultra-fine injection needles, and providing nitrous oxide sedation. Additionally, considerations for convenience and accessibility include English language support, acceptance of credit cards and electronic payments, and barrier-free accessibility.
