The typical color of a healthy human tongue is pink. A pink tongue generally indicates good oral health, with a smooth surface and even texture. It reflects a healthy blood supply and the absence of infections or diseases. Changes in tongue color, such as redness, a whitish coating, or patches, can signal potential health issues, including dehydration, infections, or nutrient deficiencies. It’s important to maintain proper oral hygiene and monitor the appearance of the tongue, as it can be an indicator of overall health.
