Burning in the mouth in and of itself is not all that uncommon. It may result 
from a variety of local or generalized oral mucosal disorders, or may be 
secondary to referred phenomena from other locations. Primary burning mouth 
syndrome, on the other hand, is relatively uncommon. Burning mouth syndrome is 
an idiopathic pain disorder, which appears to be neuropathic in origin. Thoughts 
on management of secondary and particularly primary burning mouth syndrome are 
discussed.
