Over the past 30 years, complex head and neck pain management is now a very narrow subspecialty characterized between restorative dentistry, neurology, and physical medicine. The orofacial pain specialist, a practitioner trained in diagnosis and nonsurgical treatment of chronic pains occurring in the oral and facial regions, is central to this field. This specialty is also different from general dental practice, which is basically treating the hard tissues of teeth in that this area does examine the relationships between other structures such as the temporomandibular joint (TMJ), trigeminal nerve and cervical musculature.
This field is based on the concept of referred pain and biology of the trigeminal nervous system. Although the trigeminal nerve, a cranial nerve, is the primary sensory pathway for the face, it is also an intricate web in which signals may cross. Example: Patient feels extreme pain in a healthy tooth that is actually referred from a "trigger point" in the masseter muscle or other dysfunction in the cervical spine. A clinician must be able to separate "site" and "source," a phenomenon known as heterotopic pain,8 prior to instituting treatment. Using a multidisciplinary diagnostic strategy may be beneficial in determining the actual neurological or muscle origin of the pain.
Temporomandibular Disorder or TMD is one of the most common pathologies treated by an Orofacial Pain Specialist. The temporomandibular joint is a unique "giggly MO arthrodial" joint, which means it works as both a hinge and sliding joints. the movement is smoothly bounded by fibrocartilaginous disc. The disc that becomes displaced–which oftentimes can be heard by popping, clicking’s sounds and limited range of movement–cues up the inflammatory response. Practitioners are using advanced imaging like MRI or Cone Beam Computed Tomography (CBCT) to see where the disc is. The engineering of tools that are precision calibrated to offload pressure from the joint and allow for healing of the rhetorical tissues is now possible.
Aside from mechanical joint-related issues, the specialty includes the management of other conditions characterized as "neuropathic pain," including trigeminal neuralgia or burning mouth syndrome. These don't occur due to physical injury to the tissues; it is rather a malfunctioning of how their nerves send signals to the brain. Utilizing pharmacotherapeutic protocols to calm down overstimulated nerve fibres are precisely taught to an Orofacial Pain Specialist such as membrane-stabilising medications and topical neuro-modulators. In addition, "trigger point injections" may be used to release of myofascial pain with muscle over contraction that has gone into a chronic myoplasm and become stocked in an ischemic or low blood flow state.
One link to chronic facial pain is what is referred to as the "Oral-Systemic Link." Bruxism and TMD are often comorbid with a number of different conditions including obstructive sleep apnea (OSA). Decreased airflow during sleep causes the brain to signal the jaw muscles to clench in a protective reflex. This practice causes a great deal of stress on the TMJ and muscles in the face resulting in morning soreness. As part of a comprehensive evaluation by a specialized practitioner, the patient is assessed as to their airway health and in many instances the care of this practitioner may be closely aligned with that from sleep physicians who may also prescribe treatment relating to oral appliance therapy addressing both the nature of the respiratory obstruction but also its resultant muscular endeavours.
The final pillar of expertise is "central sensitization," the psychological component of chronic pain. If this goes on for too long, the central nervous system can become 'sensitised' meaning it responds to normal touch or movement as if it were pain. That entails a "biopsychosocial" treatment approach. Among these clinical strategies are cognitive behavioural strategies, including stress reduction to deactivate the nervous system. This means that the patient is doing more than just addressing a symptom; they are actually rewiring the body’s response to and when dealing with stressors.
Current treatment regimens prioritize "first line conservatively, reversible therapy." Therefore, aggressive surgeries or permanent changes to the bite should be avoided until any inflammatory/neurological issues that may be underlying contribute your pain have been stabilized. This strategy combines an almost biomimetic approach that keeps the anatomy of tissues intact while allowing for restoration through stimulating the natural healing process using anatomically-appropriate physical and biological factors. Since facial pain can be mistaken for both sinus headaches or an ear infection, serious underlying pathologies must be ruled out.
Conclusion
In conclusion, specialized head and neck diagnostics is the framework for restoration. Through the lens of biomechanics, neurology and sleep medicine, we can put together the pieces that have so many patients with unanswered questions frustrated with traditional methods. From adjusting dislocated TMJ discs to alleviating pain from hyper-sensitive nerve pathways, each tactic is tailored towards providing life-enhancing relief. In the end, pursuing advanced clinical care is a journey to discover the source of troubling symptoms, with an evidence-based pathway into a functional, symptom-free tomorrow.
