Toothpaste?: You may be allergic to things you use on your mouth such as certain toothpaste or mouthwash. Cinnamon is likely the most common allergen. Try switching to different toothpaste or mouth wash for 10 days and observe for any changes. It is unlikely to be from food allergy which does not last this long.
