Connections Between the Gut, Chewing Muscles, and Jaw Joint Pain

Updated Feb 9, 2026

Abstract

Orofacial pain is now the most common debilitating disease affecting quality of life.

There is a complex relationship between gut health and various body systems, including the cardiovascular and neurological systems.
Recent studies suggest a connection between imbalances in gut bacteria and chronic orofacial and temporomandibular joint (TMJ) pain.
Metabolites from gut bacteria may influence pain mechanisms in different types of orofacial pain, including chronic, neuropathic, and inflammatory pain.
Gender predisposition may play a role in the experience of orofacial pain.
Non-invasive therapeutic options for treating orofacial and TMJ pain are currently being reviewed.

Simplified

Orofacial pain has become the most common debilitating disease resulting in high healthcare costs, and compromising the quality of life, speech, aesthetics and masticatory function of those affected. As its aetiology is multifactorial and as the treatment involves a multidisciplinary holistic approach, arriving at a confirmative diagnosis is challenging. Numerous studies have been published that support the bidirectional link between gut health and other organs like the cardiovascular system, respiratory system, neurological and hormonal. Recent studies indicate a potential link between gut microbiota dysbiosis and chronic orofacial and temporomandibular joint (TMJ) pain. In this review, we enumerate the link between the metabolites released by the gut bacteria and how they regulate the pain mechanism of various types of orofacial pain like chronic, neuropathic and inflammatory in the orofacial and TMJ regions. We also discuss the potential link between pain and gender predisposition. Further, we review the recent non-invasive therapeutic options which can be put forth to use for treating orofacial and TMJ pain.
