Answer

Answer

The pathophysiology of burning mouth syndrome (BMS) is not understood.

It was originally considered a psychogenic illness; however, a neuropathic mechanism for burning mouth syndrome (BMS) is currently favored. This is based on objectively measured abnormalities of physiologic responses of the trigeminal nerve in burning mouth syndrome (BMS) patients. [7, 8] There is also evidence to suggest histopathologic changes in nociceptive fibers in BMS patients. [9] The differentiation between a peripheral versus a central etiology has not been determined.
