Welcome to PreBeau Oral Care. We aim to help you maintain your oral health in a great condition. We do not perform unnecessary procedures that may compromise your oral health. We listen to your voice, and customize treatment plans to cater to your dental needs. At our clinic, our core philosophy is centered around the “No-Drill” concept, providing minimally invasive, gentle treatments utilizing the latest global technology and knowledge.
Dr. Kuniyasu Mori, DDS
Nice to meet you. I am Dr. Kuniyasu Mori, the Director of PreBeau Oral Care.
My foundation as a dental professional lies in learning cutting-edge dentistry in both
Japan and the United States.
When approaching dental care, I always prioritize the perspective of “considering systemic health starting from the oral cavity.” The origin of this philosophy comes from my physiology studies at the University of Washington. By deeply studying how the human body functions and how different organs interact, I became acutely aware of how intimately the oral environment is connected to overall health.
After returning to Japan, I honed my skills at multiple clinics and served as the Director of Kasumigaseki Dental Office starting in November 2022. In April 2026, I proudly opened “PreBeau Oral Care” here in Akasaka.
To stay at the forefront of constantly evolving dental medicine, I actively acquire certifications and participate in academic societies.
Beyond clinical practice, I am actively involved in writing, translating, and lecturing to widely share the knowledge I have gained.
Throughout my career, I have deeply pursued specialized treatments in implants and periodontics. Through this experience, I strongly realized the paramount importance of prevention—specifically, how to protect and preserve your own natural teeth.
At PreBeau Oral Care, our guiding concept is “No-Drill” dentistry. For example, our Icon treatment, which we heavily focus on, is a highly effective, non-invasive method that improves the appearance of “white spots” without drilling the tooth. As a certified instructor for this treatment, I provide care that maximizes this specialized knowledge.
“No-Drill” dentistry is not just about reducing damage to the teeth. It is the first step in preventive dentistry, and I am convinced that maintaining a healthy oral environment is directly linked to supporting your overall systemic health.
If you are thinking, “I don’t want my teeth drilled,” or “I want minimally invasive treatment that also considers my overall health,” we are here to answer your needs with advanced techniques and rich experience. I look forward to supporting your beautiful smiles and lifelong health right here in Akasaka. Please feel free to consult with us.
