Unfortunately, there is such a thing as a hairy tongue
Even though it may sound gross, it is actually possible for hair-like structures to grow on our tongue if we neglect proper dental care. A young man recently went to the dermatologist with thin black fibers on his tongue. These fibers looked a lot like human hair, and they had a yellowish color in the middle.
The condition was easier to cure than we thought it would be. When we first saw the pictures, we assumed that this man’s tongue would need surgery in order to be fixed. But, it only took 20 days of proper cleaning for his tongue to look normal again – the discoloration included.
