Dr. Denys Kovalchuk, DDS
Comprehensive dentistry in Mill Valley, with the time and care to see the full picture.
From Kyiv to Mill Valley
Dr. Kovalchuk earned his first degree in dental medicine at Bogomolets National Medical University in Kyiv, Ukraine, where dentistry is taught as part of a medical university. After moving to the United States, he completed his dental education at the University of the Pacific, Arthur A. Dugoni School of Dentistry in San Francisco, graduating with honors. He has practiced dentistry since 2008 and opened his Mill Valley practice in 2014.
Taking the Time to Get It Right
Dr. Kovalchuk's philosophy is simple: take the time to do it right. Whether you need a single crown, a cosmetic improvement, an implant, or ongoing preventive care, he starts by understanding the full picture: your dental history, your overall health, and your goals.
That full picture matters because oral health and overall health are connected. Gum disease, for example, is a chronic bacterial infection linked through systemic inflammation to heart disease, stroke, and diabetes, and the connection runs both ways. Conditions like diabetes, and many common medications, can make gum disease harder to control, while treating it can help improve blood sugar control and may reduce the inflammation linked to heart disease and stroke. Advanced salivary diagnostics, which identify the specific bacteria involved, help personalize treatment plans. Learn more about periodontal treatment and salivary diagnostics.
In practice, that means a thorough first visit. He reviews your health history, dental history, and medications, looks beyond the teeth to your gums, jaw, bite, and soft tissues, and explains what he finds and what your options are.
Treatment plans are built around your health, your priorities, and your timeline, and the work itself is done carefully and precisely. Patients often mention in their reviews how much time he takes to explain and answer questions.
Technology
The practice uses technology where it makes care more accurate or more comfortable:
- CEREC same-day crowns: custom porcelain crowns designed, milled, and placed in a single visit
- Digital X-rays: lower radiation and detailed images
- Intraoral cameras: see what Dr. Kovalchuk sees
- Intraoral scanners: precise digital impressions instead of traditional putty impressions
- Guided implant surgery: implants planned virtually in advance and placed using precise surgical guides
- Digital Smile Design: preview cosmetic changes before treatment begins
Continuing Education
Dr. Kovalchuk continues to train throughout his career, learning from international leaders in dentistry through advanced coursework in restorative, cosmetic, and implant dentistry.

The practice is at 591 Redwood Highway in Mill Valley, just off Highway 101 and minutes from the Golden Gate Bridge, with a view of the bay from the dental chair. It's an easy drive from Mill Valley, Sausalito, Tiburon, Corte Madera, and San Rafael.
Beyond the Practice
