In this episode, Howard Farran welcomes back Dr. Densen Cao — physicist, prolific inventor, and founder and CEO of CAO Group and AMD Lasers — for his first return to the show in eight years. Mentored early in his career by Dr. Gordon and Dr. Rella Christensen, Dr. Cao has spent decades developing disruptive dental technologies at the intersection of physics, materials science, and clinical dentistry.

The heart of the conversation is his newly released LEAP procedure (Laser Endodontic Ablation Procedure), unveiled at AAE 2026 after five years of FDA review and more than 100 U.S. cases. Dr. Cao explains why disinfection — not obturation — is the true key to root canal success, and how LEAP uses a low-energy diode laser to ablate residual tissue and bacteria, paired with a proprietary LEAP solution of chlorhexidine and ethanol to reach the fins and side canals. The result, he says, is a five-nines (99.999%) bacteria reduction achieved in live patients, with an independent clinical study by Dr. Rella Christensen now underway.

The discussion then moves to prevention, where Dr. Cao introduces his caries risk testing strips — which measure salivary pH and buffer capacity with a simple lick — and "Cavity Fighter" mints designed to neutralize acid and remineralize enamel during the critical window after eating. Along the way, Howard and Dr. Cao explore why a small percentage of people never get cavities, the impact of vaping and dry mouth on caries risk, the physics of curing lights, and the history behind AMD Lasers. The episode closes with Dr. Cao's reflections on COVID and disinfection, the future of AI in dentistry, and what a lifetime in physics has taught him about trusting science and data above all.

Episode #1711 : Dentistry Uncensored with Howard Farran, Howard welcomes back his friend Dr. Densen Cao — physicist, inventor, and founder & CEO of CAO Group and AMD Lasers — eight years after his first appearance.

From a groundbreaking new laser root canal disinfection procedure (LEAP) that just earned FDA clearance, to caries risk strips and "Cavity Fighter" mints that could change how we prevent decay, Dr. Cao shares what happens when a physicist tackles dentistry's oldest problems.

?? A fascinating deep dive into disruptive innovation, science, and the future of dental care.
