Noticing tongue discoloration on one fine morning could upset anyone. But seeing the tongue changing color from natural light pink to black is not a matter of concern. As black tongue is a temporary oral condition<\/a> which occurs due to overgrowth of bacteria<\/a> or fungi or buildup of protein keratin on the surface of the tongue. Of course, you would want the tongue color to get back to normal as soon as possible, but you need to understand the possible causes for better treatment and prevent recurrence. In most cases black tongue with hairy appearance clears up in just a few days without any serious medication, but if it persists for long you should consult an oral care hygienist for proper check up as this could be due to some other underlying medical condition.\u00a0<\/span><\/p>\n

Causes of Black Tongue<\/strong><\/h2>\n

The human tongue, a muscular organ covered with pink tissue called mucosa, plays a very important role in gastronomic and speech articulation functionalities. Hundreds of tiny bumps<\/a> called papillae<\/a> give the tongue its rough texture. When dead skin cells start building up on tips of papillae due to one reason or the other they start to appear longer and hairy, which get stained easily by bacteria or other coloring substances, thus making your tongue appear black or furry. Oral care experts<\/a> classify black tongue in two types based on causing factors.<\/span><\/p>\n

Black Hairy Tongue<\/strong><\/h4>\n

A protein called keratin covers the surface of the tongue, which normally gets cleaned up with dead skin cells. If keratin starts accumulating on the surface of the tongue due to one reason or the other, it may change the appearance of the tongue, making it look black and hairy. Oral care hygienists call such conditions the black hairy tongue. Here are some of the factors that boost the chances of keratin buildup on the surface of the tongue:\u00a0<\/span><\/p>\n

Poor Oral Hygiene:<\/strong> A healthy regimen of brushing, flossing, and scrapping is a must to keep oral cavity clean and healthy<\/a>. Even a minor negligence could lead to oral health challenges including black tongue. If you are not scraping your tongue regularly, dead skin cells will start accumulating making your tongue appear black.<\/span><\/p>\n

Low Saliva Secretion:<\/strong> Optimum saliva secretion ensures smooth chewing and swallowing. If saliva production is affected due to low water intake or salivary gland malfunction dead skin cells<\/a> might not get properly cleaned up, thus making your tongue appear black.\u00a0<\/span><\/p>\n

Liquid Diet:<\/strong> If you are on a liquid diet the natural scrapping stops. Chewing and swallowing hard foods keeps your tongue free of dead skin cells, which if not removed naturally or manually, will stain and make your tongue appear blackish.<\/span><\/p>\n

Side Effect of Medication and Therapies:<\/strong> If your immune system is weak to some medical conditions then it may affect your oral health<\/a>, thus causing black tongue. Medications like antibiotics might alter the delicate balance of bacteria in your oral space resulting in bacteria induced staining of papillae<\/a>. Radiation therapy could also affect your salivary glands. Some gastrointestinal medications containing bismuth subsalicylate react with traces of sulfur<\/a> in the mouth, which could make your tongue appear black.<\/span><\/p>\n

Food Habit:<\/strong> If you are a heavy consumer of caffeinated drinks, black tea, tobacco products, then chances of black tongue increases manifold as these substances stain elongated papillae very easily.\u00a0<\/span><\/p>\n

Oxidizing Mouthwashes:<\/strong> Excessive use of harsh mouthwashes<\/a> containing oxidizing agents, like peroxide, affects the bacterial ecosystem of your mouth, thus making you susceptible to black tongue development.\u00a0<\/span><\/p>\n

Pseudo-black Hairy Tongue<\/strong><\/h4>\n

If the cause is bacteria, fungus, or other oral infections, then it is called pseudo-black hairy tongue.<\/span><\/p>\n

Symptoms of Black Hairy Tongue<\/strong><\/h3>\n

Black hairy tongue (BHT) is characterized by the appearance of abnormally elongated filiform papillae on the surface of the tongue. Although the etiology of BHT is not clear, studies suggest that it is multifactorial and more prevalent among heavy tobacco and caffeine users. Depending on the underlying cause, the symptoms of this acquired and benign condition could vary from person to person. Before your tongue color changes from light pink to black, brown, or white, you will notice the surface of the tongue turning hairy due to elongation of the papillae. In most cases, people do not experience any other symptoms, but in some cases, symptoms could be:\u00a0\u00a0<\/span><\/p>\n
