ZerØ Pain Dentistry®
40 years of experience for a new vision of dental care

Dr Stéphane Diaz
​Founder of Zero Pain Dentistry®

For 40 years, I have been exploring one path: that of a dentistry that is more efficient, more ethical and pain-free.

“You don’t get a second chance to perform a first painless clinical gesture.”

My practice has been guided by a simple conviction and a clear conclusion : pain is not inevitable. Preventing, controlling and eliminating pain, for both the patient and the practitioner, is at the heart of my approach.

Trainer for 25 years

40 years of clinical experience

Thousands of dentists trained

40-year journey driven by the pursuit of excellence and a vision of care

A dental surgeon passionate about humanness, clinical excellence and transmission

From the very beginning, I have been deeply affected by patients’ pain.
The idea of causing pain, or even being confronted with their fear of pain, was unbearable to me. This sensitivity became a standard to uphold, and the driving force behind an unwavering question: How can we provide high-quality care without pain, neither for the patient nor for the practitioner?

For more than forty years, I practiced closely alongside patients, first as a general practitioner, then dedicating myself to the most complex situations in endodontics and implantology. Driven by a constant desire to progress and always do better, I explored every possible training path. My teachers, my inspirations, and even my failures shaped my practice, before I became a trainer myself, first by chance, then with growing passion as I continued learning.

It is through teaching that I learned the most: to transmit is to deepen, to observe, to structure, and to understand differently.
Since 1998, I have had the privilege of training thousands of practitioners, in France and internationally: endodontics, anesthesia, patient communication, chair-side posture, and many other topics.

A multifaceted journey: a true “Swiss Army knife” of dentistry

My path has never been limited to the dental office: training, research and development, editorial direction of a professional journal, conferences, coaching, and roles in decision-making, negotiation and communication within representative bodies at local, national and international levels.

This diversity is no accident: it reflects a continuous curiosity and a 360° vision of the profession.

Clinician, trainer, teacher, author, researcher, editor, auditor, lecturer, consultant, coach, designer, mediator…
Each of these experiences, successive or simultaneous, completed a piece of the puzzle, ultimately shaping a unique, global and integrated approach, both technical and human, to dental care: ZerØ Pain Dentistry®.

ZerØ Pain Dentistry® ?

ZerØ Pain Dentistry® is a form of dentistry that is technically demanding, compassionate, and deeply human.

A care model based on:

  • the precise control of anesthesia and clinical procedures,

  • the effective management of pre-operative pain,

  • the elimination of intra-operative pain,

  • the prevention of post-operative pain,

  • the mastery of stress and chairside communication,

  • the practitioner’s comfort as a cornerstone of quality care,

  • the patient relationship, both the starting point and the result of the method.

Caring means taking care

“You never get a second chance to perform a first pain-free clinical gesture.”

I am convinced that a calm, confident practice begins with the mastery of technical gestures, one of the essential conditions for pain-free treatment. But it goes far beyond that. It also relies on the practitioner-patient relationship: knowing how to listen, speak, stay silent, welcome without absorbing… These skills can be learned, cultivated, and transmitted, just like technical procedures.

Good treatment also requires taking care of yourself

Throughout my career, I have realized that pain does not concern patients alone. We, as practitioners, experience it as well: physical pain from posture, tension, stress, mental fatigue, the solitude of daily responsibilities… These are the silent ailments of the profession.
Learning to relieve the patient’s pain also means learning to soothe our own.

My vision

Today, my mission is to help practitioners and their teams work with comfort, serenity, ease, and confidence.

Because I now believe that true excellence in any profession requires full-time dedication, I have chosen to commit myself entirely to transmitting what forty years of clinical practice have taught me: the alliance between clinical expertise and genuine care is not only possible, it is essential.


This alliance is the foundation of high-quality dentistry that is human, precise, efficient, and visionary.
