The human tongue is normally covered with small, pinkish-white colored bumps called papillae, which are short, fine, and hairlike in appearance. Geographic tongue is known as a harmless condition affecting the surface of the tongue. These kinds of patches give your tongue a map-like, or geographic view. The normally-healed lesion in one area afterward moves to different parts of the tongue. It is sometimes called benign migratory glossitis.
Having this kind of condition may seem disturbing, but it doesn’t cause health issues and is not related to disease or malignancy. However, it can become troublesome due to tongue discomfort and sensitivity to substances, like salt, spices, and even desserts.
