➤ Overview
Tongue color is an important indicator of overall health and can reveal clues about nutrition, hydration, oral hygiene, or systemic diseases. Variations in color, coating, or texture may signal minor oral issues or serious medical conditions, including infections, liver or kidney problems, and blood disorders.
In South Korea, assessment of tongue color is commonly performed by dentists, ENT specialists, and traditional Korean medicine practitioners. Modern clinics combine visual examination, laboratory testing, and imaging to identify underlying causes and provide targeted treatment. Understanding tongue color can help in early detection and preventive care.
