I'm a dental hygienist, and I know a little about it. I assume you have been diagnosed?

There is usually a cause, such as diabetes, food sensitivities, or it could be fungal. If your dentist can't figure it out, you may want to see an oral surgeon. Sometimes, it takes a visit to the doctor and oral surgeon to get to the cause. In the meantime, you can suck on ice chips, chew surgarless gum, and swishing Milk of Magnesia can help. Stay away from whitening products and alcohol, until you know the cause. The last patient who I saw who had burning mouth syndrome, had a fungal infection in his mouth. It wasn't even obvious. Oral thrush, usually causes a thick, white coating on the tongue, or patches of white on the gums, linking of the cheeks, or soft palate. It wipes off, leaving a sore area underneath. This patient had a slight, white coating on his tongue, but that was it. It can be tough to diagnose the cause, but keep searching, until you get an answer! Best wishes!
