Woman diagnosed with rare black hairy tongue condition: Here’s what it is:

A woman in India has been diagnosed with a rare condition known as black
hairy tongue, which is characterized by a black, fuzzy coating on the
tongue. The condition occurs when the small bumps on the tongue, called
papillae, grow longer and become stained with bacteria, food, or other
substances. While the condition is harmless and typically resolves on its
own, it can be uncomfortable and unsightly. It is often caused by poor oral
hygiene, certain medications, or tobacco use. Treatment typically involves
improving oral hygiene and avoiding the underlying causes.
