Overview
Geographic tongue, also known as benign migratory glossitis, is a harmless condition affecting the surface of the tongue. It appears as smooth, red patches with white or yellow borders that may change location, pattern, and size over time. While the condition is usually benign, it can cause discomfort or sensitivity to certain foods. South Korea’s dental and medical facilities can effectively diagnose and manage symptoms.
What is Geographic Tongue?
Geographic tongue is a condition where the tongue develops irregular, map-like patches due to the loss of papillae on the surface. The exact cause is unknown, but it is considered a benign, inflammatory condition. It is not contagious and does not indicate an underlying systemic disease in most cases.
