The constant interplay between the gut microbiota and the nervous system has led to a new field of research, primarily focusing on changes in the microbial community ('dysbiosis') as a contributing factor to neurological disease and pain development. It is here that the focus of the present narrative review is aimed. Discussed will be the relationship between gut microbiota and neurological health. After detailing the nature and origins of oral neuropathic pain and chronic somatic pain, the weight of evidence linking these diseases to gut dysbiosis is highlighted. Finally, the promising therapeutic implications of re-establishing normal gut microbiota composition by probiotics or Fecal Microbiota Transplantation (FMT) are touched upon.

Symptoms related to the impairment of peripheral nerves constitute chronic disorders, often of high prevalence. Although the etiology is different, neuropathic pain conditions lead to long-term treatment deficits. This likely reflects an insufficient knowledge of the etiology of neuropathic pain conditions. Recently, an association between the presence of neuropathic pain and conspicuous changes in gut bacteria ('dysbiosis') was noticed. As a variety of bacterial strains are known to induce an inflammatory response with sequential pain symptom appearance, inflammation in the intestine gave a plausible explanation for the observations.
