Located in Higashi-Toyo, Koto Ward, Tokyo, East 21 Dental Office is a dental clinic operated by Medical Corporation Ikedakai. The clinic's core philosophy is 'Informed Choice,' an approach where dentists carefully explain the patient's condition and treatment options, then leave the decision of whether to proceed with treatment to the patient themselves. Rather than providing uniform treatments, the clinic offers customized treatment plans tailored to each individual's condition and preferences, with no two treatment plans being identical. Operating hours are from 9:30 AM to 1:00 PM and 2:00 PM to 6:30 PM, with the clinic closed on Sundays, public holidays, and during the year-end and New Year period. In terms of facilities, the clinic has a parking lot and accommodates access by car. Additionally, the clinic features barrier-free design, creating an environment where wheelchair users and those with mobility concerns can visit with peace of mind. This is a dental clinic that successfully balances a patient-centered approach respecting self-determination with thoughtful consideration for accessibility.
