A Santa Clarita Dentist Rebuilt His Practice Around One Idea: Prevent the Problem Before It Starts

SANTA CLARITA, CA — In an industry built largely around fixing what has already gone wrong, Dr. Brian Edwards set out to build something different: a dental practice where the most important work happens before a problem ever appears. That idea became Three Two Three® Dentistry, a Santa Clarita practice that has turned prevention into both a philosophy and a method, and has done so well enough to earn a 100 Dental.me Score and a 5.0-star average across 372 patient reviews.

A Founder's Reckoning

Dr. Edwards did not arrive at this approach casually. After years in practice, he grew troubled by a pattern he saw again and again: good, caring patients developing serious problems not from neglect, but because they had never been given the time, education, or modern tools to catch disease early. "I realized dentistry had become too focused on fixing problems after they happened instead of helping people prevent them in the first place," he has said of the realization that reshaped his career. Rather than accept that as the standard, he built Three Two Three® around a different premise entirely: that the best dentistry is measured not by how much a practice fixes, but by how long it keeps patients healthy in the first place.

The 323 Method: Prevention, Hygiene, Diagnostics

That philosophy now has a name and a structure. Three Two Three® organizes its entire model of care — the 323 Method — around three pillars: prevention as the foundation of every visit, hygiene as the engine of long-term health, and diagnostics as the tool that brings clarity and precision to every decision. Instead of the rushed, six-month cleaning cycle familiar to most patients, the practice builds in longer hygiene visits, advanced detection protocols, and ongoing education so patients understand not just what is happening in their mouths today, but what is likely to happen years from now. The philosophy has reached beyond the practice's own operatory walls: Dr. Edwards has shared the prevention-first approach nationally through lectures, education, and partnerships aimed at advancing hygiene-first dentistry across the profession.

Two Dentists, Two Deep Academic Pedigrees

The clinical foundation behind that philosophy runs deep. Dr. Edwards earned his degree in biological sciences cum laude from the University of the Pacific before backpacking for six months through Western Europe, New Zealand, and Australia — an experience he credits with broadening his perspective before he returned to dentistry in earnest. At the University of the Pacific School of Dentistry in San Francisco, he distinguished himself with three separate honors: the Quintessence Restorative Award for outstanding clinical performance, the OKU Clinical Excellence Award in removable prosthodontics, and the Fredrick T. West Clinical Award for his work across all five pre-doctoral orthodontic courses. He went on to practice in Orange County, Woodland Hills, and Pasadena before returning to build his own practice in Santa Clarita, the town where he grew up and where he now lives with his wife, Ashley — his high school sweetheart — and their four sons.

He is joined by Dr. Amanda Jenney, whose own path to dentistry began while studying biology at Cal Poly San Luis Obispo, drawn to what she describes as the blend of art and science the profession offers. She went on to earn her dental degree at Case Western Reserve School of Dentistry, one of the country's most respected dental education programs, and has now spent twenty years in private practice. Raised on a horse farm in Temecula, Dr. Jenney has called Santa Clarita home since 1999, raising her own family in the community she now treats.

Guided Biofilm Therapy: Prevention Made Precise

The clearest expression of the practice's prevention-first identity is its use of Guided Biofilm Therapy, an advanced, touchless cleaning technology that gently removes harmful bacteria with far greater comfort than a traditional cleaning. Paired with digital imaging, salivary diagnostics, and early disease detection, GBT allows hygienists — who are specifically trained to recognize the earliest signs of disease — to guide patients toward healthier outcomes long before a filling or crown becomes necessary. The practice treats the hygiene visit not as a routine formality but as the foundation of everything else that happens in the chair, built on longer appointments and a relationship with each patient that develops over time rather than a single rushed encounter.

What a Visit Feels Like

Patients at Three Two Three® describe a visit built around four deliberate stages: a genuine welcome, real conversation, clear explanation, and careful treatment. The goal, as the practice frames it, is that no patient leaves without understanding why they are getting cavities, what their actual gum health looks like, what risks lie ahead, and exactly what to do next. That emphasis on clarity and education, paired with a calm, judgment-free environment, has made the practice a comfortable option even for patients who typically dread the dentist's chair.

Access, Care Options, and Community Roots

Three Two Three® Dentistry is open Monday through Thursday from 8:30 a.m. to 5 p.m. and Friday from 7:30 a.m. to 4 p.m., giving Santa Clarita patients consistent weekday access at 23504 Lyons Ave #104. The practice accepts many dental insurance plans, offers flexible financing for qualified patients, and maintains a VIP Membership Plan with preventive-care benefits for patients without insurance. Beyond the clinical offering, both doctors have deep ties to the Santa Clarita Valley itself — Dr. Edwards as a hometown native raising his own family there, and Dr. Jenney as a twenty-six-year resident who has built her life and career in the same community she serves.
