enlarged circumvallate papillae

Do enlarged circumvallate papillae indicate a problem, or can they be cause by an alergic (allergic) reaction to something like toothpaste, or mouth wash. What should you do if you have enlarged circumvallate? And do they go away by there selves?

If ther are no signs of inflammation, which consist of redness, swelling, heat, and pain, you may try to avoid any toothpaste ,mouth rinse, or irritating food. If circumvallet papilla turn out positively, you can assume it's probably allergic reaction. Once they are normal, challange with suspected allergen each time. Probably you can identify which substance is the culprit.
