can iodine cause yellowing of the tongue?

[Guest guest]

I just got back from the dentist and he asked me if I had candida or liver

issues because my tongue is yellowish. It seems impossible for me to have

candida since I don't eat sugar (except I do drink wine twice a week), being

gluten free I don't eat cakes cookies etc.., I don't have any digestive issues.

I did see online that it can be related to thyroid but I don't have one...
