[|Human|] I spit in the sink and something black was mized with my saliva. my tongue is also kind of black. i had it black once before but that was after pepto tablets. i havent had pepto though so I dont know whats wrong. Im freaking out. I did have some soda though, could that be it?
[|AI|]  Helloi have gone through your query. A black tongue discoloration is most commonly caused by organisms such as yeast and bacteria growing on the surface of the tongue. These bacteria and yeast produce blood cell pigments called porphyrins which give rise to the black color characteristically seen. The overgrowth of bacteria can also cause cells of the tongue to be shed more slowly, causing the tongue to take on a hairy appearance, known as a black hairy tongue.maintaining a good oral hygiene is the best way to treat black hairy tongue. Gently brush your teeth twice a day with a soft toothbrush. Also, brush your tongue. You can use a tongue scraper to make sure you're spotless the area. If you smoke, quit. Having soda won't cause this. Antibiotics or an antifungal Chat Doctor.  Topical medications, such as retinoid (Retina) may help. Hope this ans helpsRegards
