A hairy tongue is almost always painless and rarely causes any other symptoms. Still, some symptoms or complications of hairy tongue can occur at the same time as the elongated FP. These additional symptoms include: Burning on the tongue: The bacteria or yeast growth may cause a burning or stinging sensation.
Usually these papillae are approximately 1 millimeter in length. Hairy tongue occurs due to lack of stimulation / abrasion to the top of the tongue. The result is a buildup of a protein known as keratin (the same protein that makes up the hair on your head). In severe cases, the length of these papillae can become quite long, giving a hair-like appearance to the top of the tongue (see Below and Right).
