Your tongue's color, texture, coating, and shape offer clues to your health, with signs like a white coating potentially indicating yeast (thrush) or dehydration, a red tongue suggesting B vitamin deficiency or infection (like scarlet fever), a smooth tongue pointing to iron/B12 lack, and a black, hairy look often from hygiene or medication, but persistent changes in any area need a doctor's attention as they can signal deficiencies, infections, or, rarely, oral cancer.
If any new lesions, masses, discolorations or irregular patches are noted on the tongue's surface, they may be signs of a bacterial or fungal infection, an immune deficiency or even a pre-cancerous condition. Coating. Tongue coating is complex because it can change based on diet.

Pernicious anemia causes the tongue's surface to look smooth and appear red instead of the pinkish color of a normal tongue. The tongue might also appear thick or beefy in texture. Some tongues might even be swollen or seem to have cracks.
The deficiency of vitamin B12 has a clear effect on taste as it causes disruption in epithelial cells, producing tongue pain, redness of the tongue, and the absence of papilla, thereby increasing the taste. In addition, ALA and Vitamin C have a positive impact on the sense of taste.
