Classically, burning mouth syndrome is accompanied by gustatory disturbances like dysgeusia, parageusia and subjective xerostomia.
The pathophysiology is considered as psychogenic illness but however, a neuropathic mechanism for burning mouth syndrome is currently favored. Burning mouth syndrome is sometimes described as being fairly common, and one estimated prevalence is about 1-2% of the general population.
