Causes Of Black Tongue: Symptoms, Home Remedies And More

Black tongue is a benign oral condition with temporary formation. The name of this condition may confuse you, but it won’t turn your tongue black. Instead, you may witness hairy growth on your tongue.   

Black tongue occurs when keratin named protein grows on the surface of the tongue. Excessive buildup of bacteria inside the mouth can also cause your tongue to appear blackish. The condition isn’t permanent and usually goes away without treatment.  

Keep reading to learn about the causes of black tongue. You’ll also find home treatments that will help get rid of this condition.  

What causes this condition?

Black hairy tongue and pseudo-black hairy tongue are the two types of black tongue. The cause for both is different. 

Black hairy tongue

The surface of the tongue is covered in keratin protein. Usually, keratin discharges when the skin cells discharge. But sometimes, the body stops eliminating the dead skin, and keratin grows, making the tongue look black and ugly. 

Here are some factors that elevate the chances of keratin accumulation on your tongue. 

• If you don’t regularly brush your teeth and tongue, there are higher chances that dead skin cells will build upon your tongue. 
• If your body isn’t producing enough saliva, dead skin cells will linger on your tongue. 
• Solid food items help scratch away the dead skin cells from the tongue’s surface. But if you only intake liquids, there can be a problem.  
• Certain medications can cause dry mouth, making it easier for dead skin cells to build up.  
• Weakened immunity due to health condition
• Radiotherapy
• Nerve disorder trigeminal neuralgia that affects the nerves of the face 

Why Is My Tongue Turning Black?

• Excessive use of antibiotics. Antibiotics kill good and bad body bacteria, disturbing the bacterial balance in your mouth. This helps certain bacteria and yeasts to grow. 
• Tobacco use. Chewing or smoking tobacco can stain the elongated tongue papillae.
• Drinking too much black tea or coffee can also discolor elongated papillae.
• Mouthwashes. Mouthwashes containing peroxide can disturb the balance of bacteria in the mouth.  

Pseudo-black hairy tongue

Some people may have a black furry tongue. The cause of this type is a bacterial or fungal infection. Other oral diseases can also result in a hairy tongue.  

When you have a buildup of dead skin cells on your tongue, bacteria and other substances can get caught in them. This can make your tongue look dark brown or blackish.

Symptoms

Several symptoms are associated with black tongue, all depending on the cause.  

Other than the hairs on the tongue, people with this condition rarely have other symptoms. But those who do may experience the following.  

• change in tongue color
• fuzzy tongue

Home remedies

A black tongue doesn’t cause any harm, but it tells about lingering oral issues.
