Serizawa Dental Clinic is a conveniently located dental practice in Ohara, Setagaya Ward, Tokyo, just a 2-minute walk from Daitabashi Station on the Keio Line. The clinic's treatment philosophy centers on the concept of 'mottainai' (avoiding waste), recognizing that teeth and periodontal tissues, once lost, are difficult to fully restore. Based on this understanding, their fundamental policy is to prioritize treatment methods that preserve natural teeth whenever possible. To provide treatment tailored to each patient's wishes and circumstances, the clinic emphasizes informed consent, using digital cameras, X-rays, and dental models to clearly visualize and explain the current condition of the patient's mouth. They carefully present necessary treatment options in an easy-to-understand manner. In 2022, the clinic established an in-house CT examination system, enabling more precise diagnoses. They also support online eligibility verification using My Number cards and accept Suginami Ward adult health checkups. Clinic hours are 10:00 AM to 1:00 PM and 2:30 PM to 7:00 PM on weekdays and Saturdays, with the clinic closed on Wednesdays, Sundays, and public holidays.
