Background

Hairy tongue (lingua villosa) is a commonly observed condition of defective desquamation of the filiform papillae that results from a variety of precipitating factors. The condition is most frequently referred to as black hairy tongue (lingua villosa nigra); however, hairy tongue may also appear brown, white, green, pink, or any of a variety of hues depending on the specific etiology and secondary factors (eg, use of colored mouthwashes, breath mints, candies).[1, 2] See the images below:

Pathophysiology

Precipitating factors for hairy tongue include poor oral hygiene, the use of medications (especially broad-spectrum antibiotics), and therapeutic radiation of the head and the neck. All cases of hairy tongue are characterized by a hypertrophy and elongation of filiform papillae, with a lack of normal desquamation. Normal filiform papillae are approximately 1 mm in length, whereas filiform papillae in hairy tongue have been measured at more than 15 mm in length.

Epidemiology

Frequency

United States

The prevalence of hairy tongue varies widely, from 8.3% in children and young adults to 57% in persons who are addicted to drugs and incarcerated. Hairy tongue has been reported with greater frequency in males, those who use tobacco, those who heavily drink coffee and tea, patients infected with HIV, and those who are HIV negative and use intravenous drugs.

Mortality/Morbidity

Hairy tongue is rarely symptomatic, although overgrowth of Candida albicans may result in glossopyrosis (burning tongue). Patients frequently complain of a tickling sensation in the soft palate and the oral pharynx during swallowing. In more severe cases, patients may actually complain of a gagging sensation. Retention of oral debris between the elongated papillae may result in halitosis.

Race

No racial predilection is associated with hairy tongue.

Sex

Although hairy tongue is reported more often in males, it is not uncommon in females, especially those who drink coffee or tea and/or those who use tobacco.

Age

The incidence and the prevalence of hairy tongue increases with age, possibly because a higher percentage of the population engage in activities (eg, using tobacco, drinking coffee or tea) that predispose to the condition.
