For OLP Avoidance of certain foods works the best. Some days it’s anything acidic, tomatoe based, spicy, having cinnamon, & lots of unknowns in food that set it off. The gluten thing seems to have mixed reactions. Stress is a biggy.

The active treatments I do are biotene toothpaste & mouthwashes, benedryl every night at bedtime & steroid gel for when it hurts.
I have ok days, bad days & even worse days. It’s been active now for about 4 yrs & can get pretty depressing.
