Allergies are infrequently identified in patients with burning mouth syndrome (BMS) but have been suggested as a cause of Type 3 burning mouth syndrome (intermittent symptoms). However, typically they are associated with signs of mucosal irritation. Suggested irritants include dental materials such as mercury (present in amalgam), methyl methacrylate, cobalt chloride, zinc and benzoyl peroxide. [34] Components of lotions such as petrolatum cadmium sulfate, octyl gallate, benzoic acid, and propylene glycol have been implicated. Food allergens include peanuts, chestnuts, cinnamon, and sorbic acid. [6] Nicotinic acid has also been suggested.
