For decades, temporomandibular disorders (TMD) have been seen as a dental issue, often treated with occlusal splints as the first, and sometimes only—intervention. While splints can certainly help relieve symptoms for patients with clenching or bruxism, they don’t always provide the full solution.
The reality is that many patients continue to suffer despite splint therapy. That’s not because the splint was poorly designed, but because the condition itself is frequently misunderstood. TMD is a complex, multifactorial condition, with significant contributions from the musculoskeletal and nervous systems.
Understanding this complexity is key to more effective, long-term outcomes, especially for patients whose symptoms don’t fit the traditional dental mould.
Why splints alone may not be enough
Occlusal splints can help reduce mechanical stress on the temporomandibular joints, promote a more relaxed jaw position, and protect dental structures. However, they are not designed to:
- Restore mobility in the cervical spine
- Relieve myofascial trigger points in the jaw or neck
- Rehabilitate postural issues involving the head, neck, and shoulders
- Address nervous system sensitisation or central pain processing
- Encourage better breathing patterns or break oral habits
- Restore joint mobility within the TMJ
Put simply, a splint can’t mobilise a stiff C1–C2 joint, teach diaphragmatic breathing, or re-educate poor oral posture.
Patients who clench excessively often experience compression within the TMJ joint, reducing the exchange of synovial fluid (or weeping lubrication). Over time, this leads to a loss of joint glide, a major factor in stiffness, clicking, and locking. Manual therapy is needed to restore this mobility; splints and exercises alone can’t do the job.
Looking through a neuro-musculoskeletal lens
The jaw does not function in isolation. Normal jaw function requires movement in the cervical spine, especially the upper segments, and coordination of the deep neck flexors and suprahyoid muscles.
For patients with forward head posture, a history of whiplash, or a sedentary desk-based lifestyle, restrictions in the cranio-cervical junction are common, and they can affect jaw mechanics.
Furthemore, the trigeminal nerve (the sensory nerve of the face) shares a convergence point in the brainstem with the upper cervical nerves. This explains why patients with C1-C2 dysfunction can present as facial pain, ear fullness, or even sinus-like pressure symptoms that are easily mistaken for primary TMD or ENT pathology.
TMD doesn’t always look like jaw pain
Not all patients with TMD complain of jaw pain. In fact, many are unaware that the jaw is involved at all. They may present with:
- Ear symptoms such as blocked sensation, pain, or tinnitus
- Facial pain or pressure
- Clicking or locking of the jaw
- Neck pain or stiffness
It’s not uncommon for these patients to have already seen multiple practitioners, such as dentists, ENTs and neurologists, without finding a resolution. In many cases, no one has assessed the TMJ and neck together in an integrated, functional way.
The value of hands-on, collaborative care
At our clinic, we take a multidisciplinary approach to managing TMD. Our team of physiotherapists and osteopaths are trained in orofacial pain and TMJ conditions, and we offer comprehensive, manual therapy-based care.
This may include:
- Joint mobilisation of the TMJ and upper cervical spine
- Myofascial release techniques for the jaw and neck
- Postural retraining
- Breathing education (diaphragmatic and nasal)
- Habit reversal and neuromuscular re-education
Together, these approaches help restore joint mobility, reduce muscle tension, calm the nervous system, and bring back natural, pain-free movement of the jaw.
Why collaboration matters
TMD management shouldn’t rest on the shoulders of dental professionals alone. Much like chronic back pain, it often requires a team-based approach. Medical doctors, ENTs, physios, osteopaths, and even psychologists can all play a role.
Understanding referred pain, posture, airway factors, and stress-driven habits is essential to helping these patients long-term.
In conclusion
Occlusal splints still have a place in TMD care, but they are only part of the picture. When we broaden our view to include the musculoskeletal and neural systems, we start to see more complete and lasting improvements for our patients.
If you’re seeing patients with orofacial pain, jaw clicking, persistent headaches, or ear symptoms that haven’t improved with standard care, consider referring them to our team for a targeted TMJ and cervical spine assessment. We’d be happy to work collaboratively to achieve better outcomes.
