Black: Your tongue may get black color as a result of debris and bacteria building up on its surface. It is often caused by taking oral antibiotics or an abuse of tobacco. It can be removed with careful cleaning and brushing.
Red: This is caused by a deficiency of vitamin B12. Also, scarlet fever and Kawasaki disease have red tongue symptoms.
Brown: This is one of the rare discoloring effects, and it may be a sign of one form of skin cancer-melanoma.
Yellow: Dehydration, smoking, fevers can often result with a yellow tongue. In some extreme cases, this may be a sign of liver illness.
Your tongue is not only responsible for your taste, but it can show you some signs that something else is going on in your body. That’s why you need to take care of your tongue as all the other part of your body.
