Jaw pain, clicking, and facial pain are common reasons patients come into the clinic, and the research behind how these conditions are understood keeps developing. Here is a summary of what recent peer reviewed literature says, and how it lines up with the approach used in practice.

Diagnosis comes before treatment

A recent clinical review in Rambam Maimonides Medical Journal set out a systematic framework for physicians assessing orofacial and jaw pain, sorting non-dental causes into ten categories including temporomandibular joint disorders, masticatory muscle pain, neuropathic pain, and pain referred from other conditions in the head and neck (Abboud et al., 2026, DOI). The point worth taking from this for patients is straightforward. Not all jaw or facial pain has the same cause, and getting the diagnosis right before starting treatment matters more than starting treatment quickly.

Conservative therapy has real evidence behind it, with some caveats

A systematic review of randomized controlled trials in the Journal of Oral Rehabilitation looked at myofascial release therapy, a form of soft tissue physiotherapy, for muscle related temporomandibular disorders. It found the therapy reduced pain and improved mouth opening across the included trials, though the certainty of that evidence was rated low to very low by the researchers' own GRADE assessment, and only some of the trials showed improvement large enough to be considered clinically meaningful rather than merely statistically significant (Ferrillo et al., 2026, DOI). This is a useful reminder that conservative therapy can genuinely help, while also showing why it is usually combined with other measures rather than relied on alone.

Separately, a retrospective cohort study following patients with temporomandibular joint osteoarthritis through a full year of non-invasive, multimodal management found average patient reported pain fell substantially, from roughly 4.4 out of 10 at the start to roughly 0.6 out of 10 at one year, alongside imaging signs of reduced joint inflammation (Moncada et al., 2026, DOI). The same study flagged something worth noting: half of the patients screened showed probable anxiety on a standard screening scale, which connects to the next finding.

The link between wellbeing and jaw pain

A large Swedish cohort study following over 33,000 people through routine dental checkups found that better mental and physical wellbeing were associated with a lower likelihood of developing temporomandibular disorder pain, and a higher likelihood of it resolving once present. A history of extended sick leave was associated with the opposite pattern in both directions (Vallin et al., 2026, DOI). This does not mean TMJ pain is not physically real. It means the researchers found that a person's broader health and life circumstances measurably affect how the pain behaves over time, which is one reason treatment plans often look beyond the joint itself.

Where the field is heading

An international group of TMD researchers, clinicians, and patient representatives recently ran a structured consensus process to prioritise topics for future treatment guidelines, held as a workshop at the IADR General Session in Barcelona in 2025. The highest priority topic to come out of that process was primary care management of TMD in children, with the top research questions focused on comparing self-management strategies, behavioural approaches, and occlusal splints (Wielandt et al., 2026, DOI). It is a sign that the field sees real gaps in the evidence for how milder, more common presentations should be managed, particularly in younger patients, even as surgical management of the more severe end of the spectrum, such as joint ankylosis, remains well described in the literature (Roychoudhury et al., 2026, DOI).

What this means in the clinic

Taken together, this research supports a layered approach: an accurate diagnosis first, conservative management as the default starting point for most cases, attention to the broader factors that influence how pain persists or resolves, and surgery reserved for the smaller group of patients where structural joint damage does not respond to non-surgical care. That is the same sequence used in practice, and it is reassuring to see it holding up as the evidence base continues to grow.
