TMJ Mobilization Helps Vertigo: Study Findings

A 2026 randomized controlled trial has found that adding jaw joint therapy to standard vertigo treatment can improve balance and jaw function, but does not provide extra relief from dizziness itself. The study, published in Scientific Reports, investigated whether temporomandibular joint (TMJ) mobilization could help individuals with Benign Paroxysmal Positional Vertigo (BPPV).

Why Jaw Health Might Affect Dizziness and Balance

Benign Paroxysmal Positional Vertigo is the most common cause of peripheral vertigo, triggered by tiny crystals dislodging in the inner ear’s balance canals. While highly effective maneuvers exist to reposition these crystals, some patients continue to experience residual dizziness or imbalance. This has led researchers to explore contributing factors beyond the inner ear.

“Temporomandibular joint dysfunction has been associated with vestibular symptoms, including dizziness, imbalance, and tinnitus,” note the study authors from Bahçeşehir University and Alaaddin Keykubat University in Turkey. The TMJ is a complex hinge connecting the jawbone to the skull. Dysfunction in this joint and the surrounding muscles can create tension and altered sensory input that may affect the closely connected systems responsible for balance.

This connection is why many patients with chronic tinnitus or misophonia also report jaw pain or tension. The study aimed to test if directly addressing TMJ issues could improve outcomes for people undergoing treatment for a confirmed BPPV episode.

Testing a Combined Treatment Approach

The researchers recruited 42 adults diagnosed with posterior canal BPPV. After one participant dropped out, 41 completed the trial. Participants were randomly assigned to one of two groups. The control group received only the standard treatment: canalith repositioning maneuvers (like the Epley maneuver) performed by an ENT specialist. The intervention group received the same standard maneuvers plus a weekly session of TMJ and soft tissue mobilization for four weeks.

This mobilization, performed by a physiotherapist, involved gentle techniques to improve jaw joint mobility and release tension in the chewing muscles. The primary outcome measured was the change in dizziness-related disability using the Dizziness Disability Inventory (DDI). The team also assessed jaw function using the Jaw Functional Limitation Scale and measured static balance by timing how long participants could hold a tandem stance (heel-to-toe) with eyes open.

Jaw Therapy Improves Balance, But Not Dizziness Scores

Both groups saw their dizziness disability scores improve significantly after treatment, confirming the effectiveness of the standard repositioning maneuvers. However, there was no statistical difference in dizziness reduction between the group that received extra jaw therapy and the group that did not. The addition of TMJ mobilization did not make the vertigo attacks or their perceived disability resolve faster or more completely.

The results diverged on other measures. The intervention group demonstrated a “significantly greater improvement in temporomandibular function” compared to the control group. More notably, their balance improved more. Those who received jaw therapy could maintain a tandem stance with eyes open for nearly four seconds longer, on average, than those who received only standard care. The mean difference was 3.90 seconds (95% CI 1.70-6.10; p=0.001).

“Adding temporomandibular joint and soft tissue mobilization to conventional treatment may improve balance performance and temporomandibular function in individuals with benign paroxysmal positional vertigo,” the authors conclude.

What These Results Mean for Patients

The findings have clear practical implications. For individuals with BPPV, the study reinforces that canalith repositioning maneuvers remain the essential, primary treatment for the vertigo itself. The new data does not support using TMJ therapy as a way to enhance dizziness relief from BPPV.

However, for patients who have co-existing TMJ dysfunction or who continue to feel unsteady on their feet even after successful repositioning, the study offers a potential avenue for help. Improving jaw joint function and the associated muscle tension may contribute to better postural control. This is particularly relevant because imbalance is a major risk factor for falls, especially in older adults.

The link between jaw health and sensory systems also intersects with other hearing-related conditions. For instance, the stress of chronic conditions like tinnitus can exacerbate jaw clenching, creating a vicious cycle. Techniques to manage this musculoskeletal component, similar to those explored in mind-body practices for tinnitus relief or neuroplasticity strategies, may offer indirect benefits for overall stability.

A Holistic View of Vestibular Health

This research, available with full details via its PMID: 42168393 or DOI: 10.1038/s41598-026-52637-x, moves toward a more integrated model of balance disorder management. It suggests that successful treatment may sometimes require looking at adjacent systems, even after the root cause in the inner ear is fixed.

The separation of outcomes—helping balance and jaw function but not dizziness intensity—is instructive. It shows that different symptoms may have different contributing factors, even within the same diagnosis. This nuanced understanding can help clinicians tailor rehabilitation. A patient whose main complaint is unsteadiness might benefit from a referral to a physiotherapist skilled in TMJ and cervical treatment, while a patient focused on acute vertigo spells would prioritize the repositioning maneuvers.

Furthermore, the connection between physical tension, sensory processing, and conditions like tinnitus or misophonia is well-established. As research explores links between tinnitus, depression, and sleep, the role of the musculoskeletal system as a mediator or contributor warrants attention. This study provides evidence that addressing jaw health can have measurable, positive effects on physical function, adding another tool for comprehensive patient care.
