Black Tongue: A Surprising Occurrence in Decatur, GA As the owner of Metro Decatur Dental Group PC, I am well aware of the concern and confusion that can arise when you notice a sudden dark discoloration on the surface of your tongue. This unusual condition can be alarming, but fear not, it is often harmless and can be resolved with proper care and attention.

Understanding Black Hairy Tongue Our tongues are covered with tiny bumps called papillae, responsible for our sense of taste. Under normal circumstances, the cells on the tongue’s surface shed naturally, making way for fresh cells. However, sometimes these cells don’t shed properly, leading to the accumulation of keratin, a protein, on the papillae’s surface. This buildup causes the papillae to enlarge and take on a long, hairy appearance. The trapped food debris, bacteria, and yeast within these enlarged papillae result in the tongue turning black – a condition aptly named “black hairy tongue.”

Symptoms and Culprits One of the most noticeable symptoms of black hairy tongue is the tongue’s black appearance, though it may also take on shades of green, brown, beige, or yellow depending on the bacteria present in the papillae. Along with the discoloration, individuals may experience bad breath, a metallic taste in the mouth, and irritation or gagging sensations due to overgrown papillae in the throat. The tongue’s top surface may appear furry or hairy as well.

Several factors can contribute to the development of black tongue. Extensive use of antibiotics, certain medications like oral sprayed steroids and bismuth subsalicylate, and even peroxide-containing mouthwashes can be responsible. Poor oral hygiene, dry mouth (xerostomia), and a low-fiber diet are other potential culprits. Additionally, medical conditions that weaken the immune system, such as diabetes, HIV, or undergoing radiation therapy, can make individuals more susceptible.

Effective Treatments and Prevention Fortunately, black tongue can often be managed and resolved with some straightforward steps. Increasing fiber intake in the diet aids in the removal of dead skin cells from the tongue’s surface. If medication is the cause, consulting your doctor for alternatives may be helpful. Dentists can use dental lasers to remove the hairy growths, and topical retinoids may be prescribed to exfoliate the tongue’s surface cells.

To prevent black tongue, maintaining good oral hygiene is key. Brushing your teeth twice a day for at least two minutes, using a tongue scraper or a soft toothbrush to gently remove dead skin cells after meals, and rinsing with salt water three times a day are effective measures. Drinking plenty of water, chewing gum with xylitol to increase saliva flow, and using fluoride toothpaste are also beneficial.
