Beyond the Diagnosis: Humility, Uncertainty, and the Care of Patients With Temporomandibular Disorders
by Jason Bullock, DMD, ABGD, MS
Abstract
Temporomandibular disorders (TMDs) occupy a unique space in dentistry. Although advances in diagnostic criteria, imaging, and pain science have improved our understanding of these conditions, many patients continue to present with symptoms that cannot be fully explained by objective findings alone. This disconnect creates one of the greatest challenges in TMD care: balancing scientific uncertainty with compassionate clinical practice. The absence of a definitive diagnosis should never be interpreted as the absence of disease or suffering. Rather, clinicians must recognize that uncertainty is an inherent feature of medicine and dentistry, particularly in chronic pain disorders. This commentary argues that intellectual humility—the willingness to acknowledge the limits of current knowledge while remaining committed to patient-centered care—is a fundamental clinical competency for practitioners treating TMD.

The Problem With Normal
Modern healthcare has become exceptionally proficient at identifying disease through objective testing. Radiographs reveal fractures, laboratory studies detect inflammatory processes, and advanced imaging identifies structural abnormalities with remarkable precision. These tools have transformed patient care and undoubtedly improved outcomes.
However, they have also shaped an implicit expectation: that every symptom should ultimately correspond to an identifiable abnormality.
Patients with temporomandibular disorders frequently challenge this assumption.
Many present with persistent pain despite unremarkable imaging, minimal structural pathology, or inconsistent objective findings. Others exhibit radiographic changes that bear little relationship to the severity of their symptoms. This disconnect is not unique to TMD but is common across many chronic pain disorders.
The temptation in these situations is understandable. When objective evidence fails to explain subjective suffering, clinicians may unconsciously begin questioning the symptom rather than the diagnosis.
This represents a subtle but important shift.
Instead of asking, "Why is this patient experiencing pain?" we begin asking, "Why does this patient report pain despite normal findings?"
Although these questions appear similar, they reflect fundamentally different approaches to patient care.
Pain Is Not Simply Tissue Damage
Contemporary pain science has fundamentally altered our understanding of chronic pain. Pain is no longer viewed solely as a direct consequence of tissue injury but as a multidimensional experience influenced by peripheral nociception, central nervous system processing, psychosocial factors, previous experiences, sleep quality, stress, and numerous biologic mechanisms.
This does not diminish the legitimacy of pain.
Rather, it emphasizes its complexity.
Patients with persistent TMD symptoms often exist within this complexity. Structural abnormalities may contribute to symptoms, but they rarely tell the entire story. Likewise, the absence of structural pathology should not be interpreted as evidence that meaningful pain does not exist.
Subjective experiences are not inherently unreliable simply because they cannot be quantified.
Pain remains subjective because it is experienced by a person, not because it lacks biologic reality.
The Limits of Clinical Knowledge
Medicine and dentistry are often presented as collections of established facts. In reality, both professions are defined by evolving knowledge.
History repeatedly demonstrates that diseases once considered idiopathic later become understood through scientific discovery. Peptic ulcer disease, once attributed primarily to stress and lifestyle factors, was fundamentally redefined following recognition of Helicobacter pylori. Autoimmune disorders, neuropathic pain syndromes, and central sensitization continue to evolve as areas of active investigation.
Temporomandibular disorders represent a similarly dynamic field.
Although significant advances have occurred through initiatives such as the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), substantial gaps remain in our understanding of disease mechanisms, symptom variability, and treatment response.
Recognizing these limitations is not a weakness of clinical practice.
It is an honest reflection of scientific reality.
The Role of Intellectual Humility
Healthcare traditionally rewards decisiveness. Patients understandably seek confident answers, and clinicians strive to provide them.
Yet confidence should not be mistaken for certainty.
One of the most important clinical skills in chronic pain management is the ability to communicate uncertainty without diminishing patient trust.
Statements such as:
"I do not yet know why you are experiencing these symptoms."
or
"Your imaging is reassuring, but it does not explain everything you are experiencing."
are not admissions of failure.
They are acknowledgments of the current limits of medical knowledge while affirming the patient's lived experience.
Patients rarely expect omniscience.
They expect honesty, curiosity, and commitment.
Implications for TMD Education
Dental education understandably emphasizes diagnostic classification, treatment planning, and procedural competency. These remain essential components of clinical training.
However, less attention is devoted to managing uncertainty.
Residents entering the field of TMD frequently encounter patients who have consulted multiple providers without satisfactory explanations. These interactions require more than technical knowledge.
They require communication skills.
They require emotional intelligence.
Most importantly, they require intellectual humility.
Teaching future clinicians to acknowledge uncertainty while maintaining patient confidence may prove just as important as teaching them how to interpret a magnetic resonance image or fabricate an occlusal appliance.
Redefining Success
In procedural dentistry, success is often defined by restoration, extraction, or surgical correction.
Chronic pain requires a broader definition.
Successful treatment may involve meaningful improvements in function, reductions in symptom severity, improved sleep, restoration of daily activities, or decreased fear associated with pain.
Complete symptom resolution remains an ideal outcome.
It should not be the only acceptable one.
Patients frequently judge clinical success not solely by whether pain disappears but by whether they feel heard, believed, and partnered throughout the diagnostic and therapeutic process.
Conclusion
Temporomandibular disorders remind us that dentistry is both a science and a profession grounded in human relationships. Scientific advances continue to improve our understanding of chronic orofacial pain, yet uncertainty remains an unavoidable aspect of clinical practice.
The measure of an exceptional TMD clinician is not the ability to explain every symptom immediately but the willingness to remain curious when explanations are incomplete, humble when knowledge is limited, and compassionate when patients are most vulnerable.
The absence of a diagnosis should never become the absence of care.
