From Titanium to Zirconia: How Dr. Andrés Fernández is Redefining Oral Surgery

Dr. Andrés Fernández is a leading oral and maxillofacial surgeon in Costa Rica whose career has been defined by a commitment to advancing biological dentistry and systemic health. With over fifteen years of experience, he has become recognized for tackling complex cases that others often avoid.

He now brings that expertise to “Bye Ol’ Dentistry,” the new documentary from Lolli Brands Entertainment that challenges outdated dental practices and showcases biological dentistry as the future of care. By weaving together patient stories, cutting-edge science, and the insights of pioneers like Dr. Fernández, the film highlights how oral health is inseparable from whole-body wellness.

From Conventional Surgery to Biological Innovation

Dr. Andrés Fernández is an oral and maxillofacial surgeon practicing in Costa Rica. He currently serves as the Surgeon of Bioregenerative Interventions Director at TRYBE and is the former president of the Costa Rica Academy of Oral and Maxillofacial Surgery. He has completed advanced courses at universities including Harvard and the University of Pennsylvania. For the past fifteen years, he has specialized in biological dentistry, zirconia implants, cavitation surgery, and treating the kinds of cases that most dentists either do not know how to handle or prefer not to touch.

Like many in his field, Dr. Fernández began his career trained in conventional oral surgery. He learned to extract teeth, place titanium implants, and perform jaw surgeries using standard protocols. But something felt incomplete. Patients often returned with the same problems or developed new, unexplained conditions—chronic fatigue after extractions, autoimmune flare-ups that coincided with dental procedures, or inflammation with no clear source.

The turning point came when Dr. Fernández began to see the connection between what was placed in patients’ mouths and the impact on their overall health. Metal implants, he realized, were not just replacing teeth; they were creating chronic inflammation and triggering immune responses due to biocorrosion. Extractions were not healing properly, leaving cavitations that became silent sources of systemic disease.

That realization shifted his perspective: dentistry was not just about treating teeth, but about treating people. The mouth could not be seen as an isolated system; it was integral to whole-body health.

Inside TRYBE’s Mission to Redefine Dentistry and Health

Dr. Alejandro Mora, Regenerative Aesthetics Director at TRYBE, has been his partner in this journey from the beginning. Together, they built their practice on a simple principle: whatever is placed in a patient’s mouth should support health, not compromise it. Whether Dr. Mora works on restorative cases or Dr. Fernández performs complex jaw surgery, both believe that beauty and function should never come at the expense of biology.

The incorporation of Dr. Arturo Lizano, Human Optimization Director, further strengthened TRYBE’s foundation. As head of functional medicine, he brought a deeper understanding of how oral health connects to systemic wellness, making their approach even more comprehensive.

This philosophy led the team to develop their proprietary biological protocol—simple in concept but radical in practice: remove interference, support the system, and rebuild with materials the body recognizes as safe. Every case is approached with the patient’s long-term health in mind.

By 2018, they recognized a responsibility to share their knowledge. They opened their doors to dentists worldwide who wanted to see biological dentistry in action. Since then, more than 200 doctors from the United States, Germany, Poland, Switzerland, and beyond have traveled to Costa Rica to learn from their clinic.

Showcasing Biological Dentistry on the Global Stage

When the Lolli family invited Dr. Fernández to be part of “Bye Ol’ Dentistry,” he did not hesitate. They understood what he had been witnessing for years: that conventional dentistry, despite its intentions, carries fundamental blind spots that harm patients. The film is not about dismantling a profession, but about shining a light on practices that must evolve.

What excites Dr. Fernández about the documentary is that it does more than expose problems—it presents solutions. It features professionals who work differently, not out of contrarianism, but because they have seen what truly helps patients heal. He has witnessed lives transformed when toxic burdens are removed from the mouth, and chronic symptoms resolved when cavitations are addressed—conditions that often go undetected in traditional practice.

For him, biological dentistry is not a trend or a marketing phrase. It is a recognition that dentistry can be better: more precise in diagnosis, more thoughtful in material use, and more respectful of the body’s natural ability to heal.

That vision now extends to the screen through “Bye Ol’ Dentistry,” the upcoming Lolli Brands Entertainment documentary produced by Anthony and TereZa Lolli, exposing the hidden risks of outdated practices while showcasing biological dentistry as a path to true systemic wellness. By combining powerful patient stories, scientific evidence, and the voices of pioneers like Dr. Andrés Fernández, the film underscores a message that is long overdue: oral health is the foundation of whole-body health.

Dr. Fernández and Dr. Mora have built their careers around this principle. Every day, they meet patients whose symptoms were dismissed as “just stress” or “just aging,” only to find real relief when oral health is treated as the root cause.

To Dr. Fernández, the future of dentistry lies not in reverting to old methods but in advancing with wisdom—using technologies and materials that align with the body. It is about treating the person, not just the tooth.

What excites him most about being featured in “Bye Ol’ Dentistry” is contributing to a conversation that is long overdue: one that puts patient health first, always.
