Located in Marunouchi, Chiyoda-ku, Tokyo, this dental clinic provides dental care services. Based on the director's experience of undergoing 13 cavity treatments and maintaining cavity-free teeth for over 15 years by applying knowledge from university studies, the clinic's approach focuses on two pillars: thorough preventive dentistry and precision treatment to minimize retreatment. In preventive dentistry, they perform plaque removal using Airflow and high-concentration fluoride application, placing emphasis on self-care instruction including fluoride toothpaste selection and proper use of interdental brushes and dental floss. For precision treatment, they strictly implement rubber dam isolation during cavity treatment and root canal treatment to prevent saliva and bacterial contamination, thereby minimizing adhesive failures and recurrence. In addition, all dentists and dental hygienists use microscopes, magnifying the view dozens of times to check for remaining cavities and verify the fit of fillings and crowns. The clinic also records microscope footage to show patients, helping them understand their oral condition and prompting behavioral changes. The clinic supports English, accepts credit cards and electronic payments, and provides parking and barrier-free accessibility. The implant treatment volume is minimal at about one case per month, reflecting their commitment to preserving natural teeth.
