Glossodynia (synonym: burning mouth syndrome) is thought to be a disorder w
ith a wide range of possible causes. Aetiologies may include haematological
diseases, vitamin deficiencies, dental work, hormonal factors, or infectio
ns. In addition, psychological disorders such as neuroses, depression, or p
hobias have been reported as playing a significant role in the initiation o
f burning mouth syndrome. Typically, the oral mucosa is found to be normal
in most burning mouth syndrome patients. A multidisciplinary approach appea
rs to be essential for appropriate assessment of this disorder, i.e. the di
agnostic procedure should involve dentistry, neurology, and internal medici
ne. If possible, careful treatment of underlying causes must be undertaken.
However, the replacement of suspected but unproven hormonal/nutritional de
ficiencies should be avoided.
