A Word to the Profession
On Truth, Courage, and the Future of Your Profession
Whether you graduated last spring or thirty years ago, you completed one of the most demanding educational journeys a human being can undertake. Years of sacrifice, discipline, and relentless study earned you the right to call yourself a doctor. And in the subject of this letter, every one of us was once new.
Whether the busyness of practice is still ahead of you or has already claimed years of your life — before the pressures of overhead and debt push you toward efficiency over excellence, before the culture of your profession finishes teaching you to stop asking hard questions — I want to speak to you about something that your dental education most likely failed to adequately address.
The bite. The jaw. The physiologic health of the human masticatory system.
Not as a technical checkbox. Not as an afterthought following your restorative work. But as the foundational biological reality upon which everything you do in that operatory either succeeds or fails long term.
Dental schools are extraordinary institutions in many ways. But there is a gap — widely acknowledged even by those within the system — that has persisted for generations. That gap is occlusion. The physiologic relationship between the teeth, the muscles, the temporomandibular joints, and the entire craniocervical complex.
Most dentists graduate without a working clinical understanding of how to objectively determine where the human mandible belongs physiologically. Most cannot measure masticatory muscle function. Most cannot objectively assess TMJ health. Most rely on techniques that are largely subjective — feeling for resistance, manipulating the jaw to a reference position, trusting articulating paper and clinical intuition.
And here is what makes this particularly significant: most of those dentists know it. Ask them in honest conversation and they will tell you. Occlusion and TMD are the topics that make experienced clinicians uncomfortable precisely because they sense the gap between what they were taught and what their patients actually need.
You practice in a profession that has collectively agreed — often silently — to work around a foundational problem rather than solve it. You do not have to accept that agreement.
Every biological system in nature seeks homeostasis. Unstrained, balanced, physiologically harmonious function. The cardiovascular system. The neurological system. The musculoskeletal system. Nature does not design for dysfunction — dysfunction is what happens when systems are forced to operate outside their physiologic parameters over time.
Your patient’s jaw system is no different.
The question that should drive every clinical decision you make is this:
Is this patient’s masticatory system functioning in genuine physiologic health — objectively, measurably, reproducibly — or are we simply managing their adaptation to dysfunction?
That is not a philosophical question. It is a clinical one. And the remarkable thing is that today we have the instrumentation to answer it objectively. Surface electromyography can measure muscle function and dysfunction in real time. Jaw tracking technology can map mandibular movement with precision. Low frequency TENS can relax musculature to reveal a physiologic resting position uncontaminated by muscle memory and engram patterns. Joint vibration analysis can assess TMJ health objectively.
These are not experimental tools. They carry FDA clearance. They are internationally recognized. They have substantial peer-reviewed research supporting their validity and reliability.
The question worth sitting with is not whether these tools work. The question worth sitting with is why measuring the physiologic health of the masticatory system objectively is not already the standard of care in dentistry.
You will be told many things in your career with great authority and confidence. You will be told what the standard of care is. You will be told which approaches are evidence-based and which are controversial. You will be told which CE courses are mainstream and which are fringe. You will be told, implicitly and explicitly, where the boundaries of acceptable thinking in your profession lie.
Here is what history teaches us about those boundaries: they are almost always drawn by people with something to protect.
Semmelweis was institutionally destroyed for insisting doctors wash their hands. Barry Marshall drank H. pylori to prove that ulcers were bacterial rather than psychological — the consensus had been catastrophically wrong for decades while patients suffered unnecessarily. Dentistry is not immune to this pattern.
Consensus is not truth. Consensus is the current majority position. Those are fundamentally different things.
This does not mean you should reject consensus reflexively. It means you should hold consensus to the same standard of evidence you apply to everything else. Ask where it came from. Ask what it is actually based on. Ask what it cannot explain. Ask what happens to the patients it fails.
For decades occlusal dentistry has been divided into camps. The gnathologists on one side — rigorous, mechanically precise, focused on joint position and occlusal morphology. The neuromuscular practitioners on the other — physiologically driven, focused on muscle health and function, pioneering the use of objective instrumentation to measure biological responses rather than assume them.
Both camps produced genuine insights. Both camps also carried blind spots born of their own limitations.
What the most advanced thinking in this space has recognized is that separating these two frameworks was itself the problem.
Gnathology gives you the mechanical precision of joint position and occlusal morphology. Neuromuscular science gives you the physiologic, measurable, muscle-based reality of how the system actually functions. Combining both with objective instrumentation is arguably more complete than either camp alone. That is a sophisticated position, and it is one the critics rarely engage with honestly because most of them are firmly planted in one camp.
The synthesis is not a compromise. It is an advancement. It is what happens when clinicians refuse to plant their flag in one camp and instead ask what the evidence actually supports across the entire landscape of the question.
Your patients will not come to you asking about centric relation or myocentric position or gnathologic versus neuromuscular philosophy. They will come to you with headaches that no one has been able to explain. With jaw pain that has been dismissed or misdiagnosed for years. With worn teeth and broken restorations and muscle tenderness and clicking joints and a history of being told everything looks fine on the X-ray.
They are not asking for your philosophy. They are asking to be genuinely helped.
The dentist who can objectively measure their masticatory muscle function, assess their joint health, determine their physiologic mandibular position, and build treatment upon that measured foundation rather than assumption and educated guessing — that dentist can help them in ways that most of their previous providers could not.
That dentist is who you have the opportunity to become.
Everything described in this letter requires courage. The courage to invest in knowledge and instrumentation that your colleagues may question. The courage to tell a patient that their long-standing symptoms have a physiologic explanation that can be objectively identified and addressed. The courage to challenge a system that has grown comfortable with its own inadequacies. The courage to keep asking hard questions long after the culture of your profession has stopped expecting you to.
Nature does not design biological systems for dysfunction. Your job — your deepest professional obligation — is to align your clinical practice with how the human body is actually designed to function.
Measure. Observe. Question. Synthesize. Serve.
The future of dentistry belongs to the clinician who refuses to guess when they can measure, refuses to assume when they can observe, and refuses to accept comfortable consensus when the evidence points somewhere more demanding and more true.
That future starts with you.
Written in the spirit of honest inquiry, for every new dentist with the courage to ask the questions the profession has too long avoided.
