Based on my work as a dystonia researcher with observations drawn from thousands of patients, I have found that dental and jaw-related issues extend well beyond those diagnosed solely with oromandibular dystonia. A noteworthy proportion of individuals across various dystonia subtypes—including cervical dystonia, blepharospasm, spasmodic dysphonia, and even limb dystonias—exhibit symptoms such as temporomandibular joint (TMJ) dysfunction, bruxism, dental displacement, and accelerated tooth wear.
Dental and Oral Health: The Foundation for General Well-Being
It is increasingly recognized that dental and oral health play a critical role in overall health. Poor oral health, including issues like chronic TMJ disorders, tooth wear, or bruxism, can contribute to systemic problems such as cardiovascular disease, diabetes, and even respiratory complications. For dystonia patients, addressing dental and oral symptoms is especially important because they not only affect daily comfort and functionality but also have a downstream effect on general physical well-being.
By integrating specialized oromandibular exercises with coordinated care from dental and neurological professionals, our approach targets the root neuromuscular dysfunctions. This comprehensive strategy is designed to alleviate oral symptoms, support dental health, and ultimately enhance your overall quality of life.
Study Results: Dental and Oromandibular Issues Among Dystonia Patients
In my clinical practice as a dystonia researcher, I observed that dental and jaw-related issues appear to vary across different dystonia subtypes. To explore this further, I reviewed clinical data from 809 patients diagnosed with dystonia. The findings are summarized as follows:
| Dystonia Type | Total Patients | Patients Reporting Dental Symptoms | Percentage with Dental Symptoms |
|---|---|---|---|
| Cervical Dystonia | 436 | 327 | 75.0% |
| Blepharospasm | 145 | 44 | 30.3% |
| Oromandibular Dystonia | 86 | 73 | 85.0% |
| Hand Dystonia | 61 | 6 | 10.0% |
| Leg Dystonia | 43 | 4 | 10.0% |
| Spasmodic Dysphonia | 38 | 11 | 28.9% |
These results demonstrate that dental and oromandibular symptoms—such as TMJ dysfunction, jaw deviation, bruxism, dental displacement, and tooth wear—are notably prevalent among patients with cervical (75%) and oromandibular dystonia (85%). In comparison, patients with blepharospasm and spasmodic dysphonia show a lower prevalence (around 30%), and only about 10% of those with limb dystonias report such issues.
Mechanisms Contributing to Dental and Jaw Issues
Several factors contribute to the development of dental problems in dystonia patients:
-
Asymmetric Muscle Tension: Dystonic activity in the masseter and pterygoid muscles can lead to uneven forces on the jaw, resulting in TMJ disorders and bite misalignment.
-
Tongue Dystonia: Involuntary tongue movements can exert pressure against the teeth, causing dental displacement over time.
-
Chronic Jaw Spasms: Repetitive, forceful lateral jaw movements may lead to condylar damage and exacerbate TMJ dysfunction.
These mechanisms highlight the complex interplay between dystonic muscle activity and dental health.
Dental Splints and Jaw Alignment in Dystonia Management
Recent research has explored the use of dental splints to alleviate dystonia symptoms by correcting jaw misalignment. For instance, a study published in the Journal of Craniofacial Surgery found that occlusal stabilization appliances (OSAs) can reduce cervical dystonia symptoms by promoting muscle relaxation and improving jaw alignment.

Similarly, a pilot study demonstrated that interventions targeting the TMJ through devices like the KIDTA appliance can mitigate the severity of dystonic contractions and enhance posture. PMC
These findings suggest that dental splints may serve as a valuable adjunct therapy for certain dystonia patients, particularly those with concurrent TMJ disorders.
Oromandibular Rehabilitation: Enhancing Neuromuscular Modulation
In our Dystonia Recovery Program and our dedicated Oromandibular Exercises Class, we offer an extensive and specific set of exercises designed to “retune” the neuromuscular pathways affected by various forms of dystonia. These protocols aim to restore a more balanced and coordinated function of the muscles involved in jaw, facial, lingual, and oral movements. When used in conjunction with appropriate treatment provided by your neurologist and dentist, these exercises can help improve overall quality of life and dental health by reducing symptoms such as TMJ dysfunction, bruxism, dental displacement, and accelerated tooth wear.
Our evidence-informed approach is tailored to the needs of each individual, empowering patients to actively participate in their own recovery process and complement clinical treatments for sustained improvements in neuromuscular regulation.

Our approach is evidence-informed and tailored to the needs of each individual, acknowledging that dystonia’s manifestations can vary widely. In this way, we empower patients to actively participate in their own recovery process, complementing clinical treatments and contributing to sustained improvements in neuromuscular regulation.
