Burning mouth syndrome
An intense burning sensation on the tongue, often at the tip of the tongue.
The burning mouth syndrome tends to develop in supertasters and post-menopausal women.
Supertasters have an unusually large density of taste buds, each surrounded by pain fibers.
Post-menopausal women with the burning mouth syndrome often lose their ability to sense bitter tastes.
Clonazepam, an anti-seizure drug, is reportedly effective in treating burning mouth syndrome in more than 70% of patients.
