At Miguel De Leon, DMD in San Mateo, CA, we believe dentistry is about more than just teeth. Your mouth is a gateway to your entire body, and every decision we make is guided by the belief that oral health and overall health are deeply connected. Through a comprehensive approach that includes advanced diagnostics, minimally invasive treatment, and a systems-based understanding of oral health, we help patients achieve outcomes that support their total wellness—not just their smile.

What Is Comprehensive Oral-Systemic Care?
Comprehensive oral-systemic care considers how your dental health interacts with other systems in your body. Rather than treating isolated issues like cavities or gum disease, Dr. De Leon looks at the bigger picture—examining how inflammation, bacteria, airway issues, diet, and lifestyle impact not just your teeth and gums, but your sleep, cardiovascular health, and immune system. This model of care allows us to address root causes, not just symptoms, and create personalized treatment plans based on your unique risk factors and wellness goals.
Leveraging Technology For Deeper Insight
Our office is equipped with some of the most advanced dental technology available, designed to elevate diagnostics and reduce the need for invasive treatments. Tools like digital imaging, 3D scanning, and real-time salivary diagnostics allow us to analyze your oral environment with exceptional accuracy. We also offer saliva pH testing and sleep apnea screening—tests that provide critical data about your body’s balance and function. With this information, we can make informed decisions that promote longevity and comfort in your care.
Conservative Dentistry Guided By Precision
Dr. De Leon follows a philosophy of conservative care: treat only when necessary and always prioritize preserving natural tooth structure. Thanks to our precision diagnostics, we’re able to catch potential issues earlier—before they evolve into more serious problems. This means smaller restorations, fewer procedures, and better long-term outcomes. Whether we’re restoring a tooth or adjusting your bite, our goal is to intervene as little as possible while still providing the highest standard of care.
Kois-Inspired Risk-Based Care Planning
Our approach is rooted in continuing education and evidence-based systems, including the respected Kois Center methodology. This framework allows us to assess each patient’s individual risk factors across categories like periodontal health, occlusion, function, and esthetics. From your first visit, we’re using science-backed tools to determine what’s most important for your health—and how to prioritize treatments in a way that aligns with your overall wellbeing. By focusing on long-term stability rather than short-term fixes, we create plans that are both proactive and sustainable.
Airway & Sleep Health Matter
Sleep-disordered breathing, including conditions like obstructive sleep apnea, can silently impact your energy levels, focus, and heart health. We incorporate sleep health screening into our exams because your airway function is just as critical to your wellness as your bite or gum health. If you’re waking up tired, grinding your teeth at night, or struggling with concentration, our screenings can identify issues early—and connect you with solutions ranging from oral appliance therapy to collaborative care with medical specialists.
Why Patients Trust Miguel De Leon, DMD
At our practice, no two patients receive the same treatment plan—because no two patients are the same. Dr. De Leon listens closely, evaluates comprehensively, and collaborates with each individual to create care strategies that work with their biology, not against it. Our commitment to modern technology, continuous learning, and compassionate care is what sets us apart—and it’s why patients throughout San Mateo, CA turn to us for care that’s thoughtful, effective, and life-enhancing.
