Transient Lingual Papillitis: Symptoms, Causes & Treatment

Transient lingual papillitis is an inflammation of the fungiform papillae, the small structures on the tongue that contain taste buds. It causes small bumps on the tongue that may be white or red and can appear alone or in clusters.

These bumps may be painful and can cause a burning, tingling, or itchy sensation. Transient lingual papillitis may be triggered by tongue irritation, viral infections, hormonal changes, smoking, or stress.

Treatment is not always necessary, as the condition usually clears up on its own within a few days. However, if symptoms are severe, keep returning, or do not improve, a primary care provider or dentist should evaluate the cause and recommend appropriate treatment.

Main symptoms

The main symptoms of transient lingual papillitis include:

• One or more small bumps on the tongue

• Small white, yellow, or red swollen bumps on the tongue

• Pain or discomfort, even when not eating or drinking

• A burning, tingling, or itching sensation on the tongue

• Increased sensitivity to hot foods

• Changes in taste or dry mouth

The bumps caused by transient lingual papillitis may appear on the sides of the tongue, the tip, or the top surface. In some cases, the bumps are painless, and swelling may be the only symptom.

Symptoms usually go away within a few hours to 2 or 3 days. However, they may last longer or return repeatedly.

If symptoms last longer than expected or keep coming back, see a primary care provider or dentist. Children should be evaluated by a pediatrician to confirm the diagnosis and determine whether treatment is needed.

Confirming a diagnosis

Transient lingual papillitis is diagnosed based on a physical exam and review of symptoms. A primary care provider, dentist, or pediatrician can usually make the diagnosis by examining the tongue.

In most cases, no tests are needed. However, if the diagnosis is unclear, the doctor may perform a biopsy of the tongue bumps to confirm transient lingual papillitis, identify an underlying cause such as an infection, and rule out other conditions with similar symptoms, including human papillomavirus (HPV).

Possible causes

Transient lingual papillitis is caused by inflammation of the fungiform papillae, which are located mainly on the sides and tip of the tongue but are also found on the top surface.

Factors that may increase the risk of developing transient lingual papillitis include:

• Mechanical trauma, such as burning the tongue with very hot food or biting the tongue

• Irritation from orthodontic appliances or rubbing against the teeth

• Food allergies

• Acidic, spicy, or very sugary foods

• Stress and lack of sleep

• Poor nutrition

• Hormonal changes during the menstrual cycle or menopause

• Smoking or excessive alcohol use

Inflammation of the fungiform papillae may also be associated with dental tartar, dental fillings, or geographic tongue.

Another possible cause is a viral infection, such as herpes simplex virus (HSV), which has been suggested as a possible trigger for recurrent episodes of transient lingual papillitis.

Main types

Transient lingual papillitis can be classified based on its symptoms and the appearance of the tongue lesions. The main types include:

1. Classic transient lingual papillitis

Classic transient lingual papillitis usually causes painful red or white bumps on the tip of the tongue that last about 1 to 2 days before going away on their own.

2. Keratotic papular lingual papillitis

Keratotic papular lingual papillitis causes multiple white or yellow bumps on the surface of the tongue without other symptoms. This type may recur over time.

3. Eruptive lingual papillitis

Eruptive lingual papillitis develops suddenly and mainly affects children. It causes bumps on the tongue, especially on the tip and sides, along with fever, swollen lymph nodes, difficulty eating, and excessive drooling.

Some people may also develop blisters or fissures on the tongue, sores, redness, or crusting at the corners of the mouth, a condition known as angular cheilitis.

This type may last for several weeks and can come back over time. It may be linked to a viral or bacterial infection.

4. U-shaped transient lingual papillitis

U-shaped transient lingual papillitis is characterized by scattered pink patches on the tongue, a burning sensation in the mouth, tongue swelling, or canker sores.

This type has been associated with COVID-19 because SARS-CoV-2 can infect the lining of the mouth. It may also occur after oxygen therapy or with poor oral hygiene.

Treatment options

Treatment for transient lingual papillitis should be guided by a primary care provider, dentist, or pediatrician. In many cases, no treatment is needed because symptoms usually improve within a few days.

To help relieve pain and discomfort, your provider may recommend:

• Rinsing your mouth with warm salt water

• Antiseptic mouthwash

• Oral anesthetics

• Topical corticosteroids, such as triamcinolone acetonide

• Cold foods and drinks

Your provider may also recommend avoiding acidic and spicy foods, candy, and chewing gum. According to the American Dental Association, teeth should be brushed twice a day for 2 minutes using fluoride toothpaste.

For eruptive lingual papillitis, pain relievers or nonsteroidal anti-inflammatory drugs (NSAIDs), such as acetaminophen or ibuprofen, may be recommended. Antibiotics may also be prescribed if a bacterial infection is confirmed.
