Black hairy tongue: Causes, symptoms


Black hairy tongue can make many people feel scared because of the name but it is actually a harmless condition. Black hair on the tongue is caused by an overgrowth of bacteria or fungi in the mouth. Black hair on the tongue is easily remedied by regular oral hygiene.

1. What causes the tongue to grow black hairs?


Black hairy tongue is caused by too much bacteria or yeast growing in the mouth. The bacteria accumulate on small, round spikes, called papillae. These papillae are located along the surface of the tongue. Instead of shedding and renewing at regular intervals, papillae begin to grow and lengthen, creating hair-like hairs. They can grow up to 15 times their usual length.
Black hairy tongue can also be due to increased keratin production or decreased demyelination (shedding of surface epithelial cells). A diet of whole soft foods also prevents the papillae on the tongue from wearing out naturally, which results in them becoming longer.
In a healthy human tongue, the papillae will be pinkish-white. But as they grow, pigments from food, drink, and possibly bacteria or yeast get caught in the papillae, staining the tongue a different color. The most common is black, hence the name black feathered tongue. However, the tongue can also turn brown, yellow, green, or a variety of other colors. Color is the result of the food, drink or products you consume.

Black hairy tongue is more common in men over 40 (with a history of poor oral hygiene, smoking, and antibiotic use), as well as those on intravenous medication or HIV positive. .
Black hairy tongue is uncommon in infants and, if present, is more likely due to bacterial and fungal colonization, rather than infection or antibiotic use, or a family history of a medical syndrome. Black hairy tongue in children usually subsides on its own and goes away after a few weeks.

2. Symptoms of a black hairy tongue


Except for the unusual appearance of the tongue, most people with black hairy tongue do not experience any other unpleasant symptoms. But in cases where too much Candida albicans yeast grows, it can cause a burning or stinging sensation on the tongue, known as glossopyrosis.
Some people may experience:
A tickling sensation on the back of the palate due to excessive hair growth. Feeling a bad smell in your mouth or feeling nauseous. Changes in taste caused by hairs growing so long that they cover the taste buds, preventing the ability to taste food properly. More seriously, black hair on the tongue can lead to a feeling of tightness in the throat, especially when swallowing. Sometimes, food trapped inside papillae too long can also cause bad breath. Bacteria or yeast growth can also cause odors. In this case, using mouthwash to get rid of the smell made the problem worse.
