Taking medications like Pepto-Bismol, (or other drugs) that have bismuth as an ingredient, can cause a black discoloration or staining on your tongue for a few days. Other causes of a black tongue are debris, bacteria, or other organisms can collect on the papillae and result in discoloration. A black hairy tongue is a temporary and harmless condition that is often caused by an overgrowth of bacteria in your mouth. Certain types of bacteria accumulate on the papillae (the small projections that cover the tongue) and create red blood cell pigments, which can make the tongue look black.
If this discoloration does not go away within a week or worsens, see your doctor.
