Daizawa Dental Clinic, located in Daizawa, Setagaya Ward, Tokyo, supports the oral health of the community as a specialized dental clinic. One of the clinic's key features is its strong commitment to preventive dentistry. Through parent-child tooth brushing guidance and dental IQ improvement programs, the clinic emphasizes preventive care from early childhood, providing comprehensive support so that entire families can maintain oral health over the long term. The clinic maintains high standards for infection control, having introduced Class B autoclaves, which meet the world's highest standards, and using extraoral vacuum systems to keep the indoor air environment clean, ensuring a safe treatment environment. During examinations, the clinic practices informed consent by displaying intraoral photos and X-ray results directly to patients on a monitor in front of the dental chair, carefully explaining treatment options. The clinic's fundamental approach is not to perform forced procedures, but rather to propose multiple treatment methods tailored to each patient's values, lifestyle, and oral condition. For orthodontic treatment, the clinic offers clear aligner therapy using transparent devices, allowing a wide range of patients from elementary school students to adults to straighten their teeth discreetly. In September 2025, the clinic became a certified clinic for GBT (Guided Biofilm Therapy) advocated by EMS Switzerland, further strengthening its system for providing scientifically-based preventive care. The facility is barrier-free and accepts credit cards and electronic payments, making it a convenient dental clinic widely used by diverse patients.
