Black Hairy Tongue

Symptoms Of Black Hairy Tongue

Typically, the sole symptom is the altered appearance of your tongue, which isn't typically accompanied by pain. However, in some instances, you might also experience:

• Bad breath

• Dry mouth

• Altered or metallic taste

• Gagging or tickling sensation in the mouth

• Nausea

• Hairy tongue

• Bad breath

• Burning sensation (if caused by fungi- candida albicans)

While often treatable at home, mouth discoloration can signal more serious conditions. If you notice discoloration on your tongue, schedule an appointment with your doctor.

Causes Of Black Hairy Tongue

Hairy tongue happens when the top of the tongue doesn't get enough stimulation or abrasion, leading to a buildup of keratin (the same protein found in hair). In more severe cases, the papillae on the tongue can grow long, making it look like the tongue's surface is covered with hair. When these papillae don’t shed properly, food, bacteria, and sometimes yeast can get trapped, creating a mesh-like effect.

This buildup can cause the tongue to change color, appearing brown, white, green, or pink, depending on the cause. Certain mouthwashes, candy, or even specific bacteria and yeast can make the tongue look black, known as "black hairy tongue."

Risk Factors Of Black Hairy Tongue

Black hairy tongue is usually harmless, but several factors can increase the chances of developing it. These include:

Poor oral hygiene: Not brushing or cleaning the tongue can lead to a buildup of dead cells and bacteria.

Tobacco Use: Smoking or using tobacco products can cause discoloration and lengthening of the papillae.

Excessive coffee/black tea consumption: Drinking lots of coffee or black tea can stain the tongue and encourage bacteria growth.

Alcohol and intravenous drug use: Alcohol abuse and intravenous drug use are recognized risk factors for black hairy tongue.

Xerostomia (dry mouth): Dry mouth, often caused by medications or medical conditions, creates an environment where bacteria thrive on the tongue.

Medication use: Some medications, like antibiotics or bismuth-containing products (e.g., Pepto-Bismol), can disrupt the mouth's bacteria balance.

Weak immune system: Illnesses that weaken the immune system, such as HIV or cancer, can make it harder to control mouth bacteria.

Recent radiation therapy: Radiation therapy to the head and neck region is an important risk factor for black hairy tongue.

Diet: Liquid diets or foods that lower the tongue's pH, like herbal teas and sugars, may encourage bacterial growth.

Certain medications: Both systemic and local medications, including antibiotics like penicillin, aureomycin, erythromycin, doxycycline, and neomycin, have been implicated in the development of black hairy tongue.

Age and Gender:  It is more common in older adults and affects men three times more often than women.

Underlying medical conditions: Certain medical conditions, like HIV, advanced cancer, trigeminal neuralgia, and general illness, can raise the risk of black hairy tongue. Trigeminal neuralgia, specifically, limits tongue movement, which prevents the normal shedding of the tongue's surface cells.

Diagnosis Of Black Hairy Tongue

The diagnosis of black hairy tongue is usually straightforward and made through a clinical examination by a doctor or dentist. The condition is visually recognizable by the darkened and elongated filiform papillae on the tongue’s surface. The following steps are typically involved in the diagnosis:

I. Physical examination

A doctor or dentist will visually inspect the tongue to evaluate its color, texture, and any abnormalities. This examination helps rule out other potential causes of tongue discoloration, such as fungal infections (like oral thrush) or other underlying medical conditions.

II. Laboratory tests

1. Oral swab test: A swab from the tongue can be taken to identify any bacterial overgrowth contributing to black hairy tongue. This helps determine if specific bacteria are causing the discoloration or elongation of the papillae.

2. Fungal scrapings: Scrapings from the affected area may be analyzed to check for fungal infections, such as yeast, which can also lead to a black hairy tongue.

3. Tongue biopsy: In rare cases, a biopsy of the tongue tissue may be performed to rule out other conditions or confirm the diagnosis. This ensures that no underlying health issues are present.

If you suspect you have a black hairy tongue, it’s important to seek professional advice for proper diagnosis and treatment.

Prevention Of Black Hairy Tongue

Preventing black hairy tongues involves adopting good oral hygiene practices and making lifestyle changes to reduce risk factors associated with the condition. Here are some preventive measures:

1. Limit staining substances: Reduce your intake of coffee, tea, tobacco, and alcohol, as these can contribute to discoloration and buildup on the tongue.

2. Adjust your diet: Consider a healthier diet that includes more fruits and vegetables to support oral health and reduce tongue buildup.

3. Choose the right mouthwash: Switch to a mouthwash that does not contain peroxide or other oxidizing agents, which can exacerbate the condition.

4. Consult About Medications: If you or your doctor suspects that a medication may be contributing to black hairy tongue, discuss alternatives or adjustments with your healthcare provider.

5. Promote oral hydration: Ensure adequate hydration by drinking plenty of water to keep your mouth moist.

Treatment Of Black Hairy Tongue

Black hairy tongue is a benign condition that can usually be managed through good oral hygiene and lifestyle changes. Although there are no specific medications approved solely for its treatment, some products may help alleviate symptoms and promote tongue health. 

Here are a few examples:

1. First-Line Treatment

Discontinue inducing medications: If medications such as antibiotics or antipsychotics are identified as contributing factors, discontinuing these drugs is essential to address the condition.

Note: A person who develops black tongue as a result of antibiotic use may need to switch antibiotics.

Tongue brushing: Gently brush the tongue with a soft toothbrush or tongue scraper to remove debris and bacteria.
