A 2003 literature review article stated researchers were connecting eugenol and other dental pain relievers, nerve injections, and possible damage to the lingual nerve with Burning Mouth Syndrome. Take a look and see what you think, but I have long suspected a link between dental work, oral surgery, and eventual extraction of my front teeth to the resultant burning mouth pain I have suffered for over a decade.
This is not, of course, the only cause possible. There are many people with BMS who have not had dental work done near the time of onset and so other factors must be in play.
