This book represents the culmination of a sustained and deeply personal inquiry into the intersections of professional practice, lived experience, spiritual reflection, and human transformation. The Smile Gate: A Shamanic Journey Through the Teeth of Time was conceived as an exploration of how the human body, particularly the teeth, bones, jaw, and voice, may function not only as biological structures but also as vessels of memory, emotion, identity, trauma, healing, and consciousness.

For many years, Marc Mortiboy's work as a dentist placed him in close relationship with pain, fear, illness, and the silent emotional histories often carried within the body. Over time, questions began to emerge that conventional clinical frameworks alone could not fully answer. Why do certain patterns repeat within families and individuals? Why are emotional experiences so often reflected physically in the mouth and body? Why do trauma, identity, voice, and self-worth appear so intimately connected to oral health and wellbeing? These questions gradually led him beyond the boundaries of traditional practice and into wider explorations of healing, spirituality, ritual, symbolism, and ancestral wisdom.

The purpose of this work is therefore twofold. First, it offers a narrative journey that situates personal experience within broader questions of meaning, embodiment, consciousness, suffering, and transformation. Through story, memory, symbolism, and reflection, the book explores the ways human beings seek healing not only physically, but emotionally, spiritually, and psychologically. Second, it seeks to provide readers with reflections, insights, and practices that may serve as points of orientation within their own explorations of health, spirituality, emotional healing, and self-understanding.

Some passages arise directly from lived experience, while others speak through metaphor, dream, vision, and spiritual interpretation.

This book is intended for a broad readership, including those interested in the meeting point between scientific knowledge, lived experience, symbolic interpretation, spiritual philosophy, and holistic approaches to healing.

The practices, ideas, and symbolic frameworks described throughout this book are presented as invitations to reflection rather than prescriptions. Readers are encouraged to approach the material with openness, discernment, curiosity, and personal responsibility, taking from it only what genuinely resonates with their own experience and understanding.
