The COVID-19 pandemic has presented a wide range of symptoms, many of which extend beyond the commonly known fever, cough, and loss of smell. One less publicized but increasingly reported symptom is tongue pain. But is there a direct link between COVID-19 and a painful tongue, or are other factors at play? Let’s delve into the possible connections, potential causes, and what you can do to find relief.
Understanding the Connection: COVID-19 and Oral Manifestations
While respiratory symptoms are the hallmark of COVID-19, the virus can affect various organ systems, including the oral cavity. Researchers are discovering that oral manifestations, such as taste alterations, dry mouth, and yes, even tongue pain, can be associated with COVID-19.
Taste Alterations and COVID-19
Loss of taste (ageusia) and distorted taste (dysgeusia) are well-documented symptoms of COVID-19. These alterations can indirectly contribute to tongue discomfort. When your sense of taste is compromised, you might find yourself consuming foods or beverages that are too hot, too spicy, or too acidic, leading to tongue irritation and pain. The frustration of not experiencing flavors properly can also lead to dietary changes that further exacerbate oral sensitivity.
Dry Mouth and its Impact on Tongue Health
COVID-19 can sometimes lead to dry mouth (xerostomia), either as a direct effect of the virus or as a side effect of medications used to treat the illness. Saliva plays a crucial role in maintaining oral health. It helps neutralize acids, remineralize teeth, and wash away food particles and debris. When saliva production is reduced, the tongue becomes more vulnerable to irritation, inflammation, and pain. A dry tongue can also feel rough and uncomfortable, further contributing to the sensation of pain.
Direct Viral Impact on Oral Tissues
Some theories suggest that the SARS-CoV-2 virus, responsible for COVID-19, can directly infect the cells in the oral cavity, including those of the tongue. The ACE2 receptor, which the virus uses to enter cells, is present in oral tissues, making them a potential target. This direct infection could lead to inflammation, ulceration, and pain in the tongue. While research is ongoing, studies have detected the virus in saliva and oral mucosa, supporting this possibility.
Possible Causes of Tongue Pain During or After COVID-19
Tongue pain, medically termed glossodynia, can stem from various underlying causes. Determining the precise reason for tongue pain during or after a COVID-19 infection can be complex. However, several factors may contribute.
COVID Tongue: A Distinctive Presentation?
“COVID tongue” isn’t a formal medical term, but it’s used to describe a range of oral symptoms that some individuals experience during a COVID-19 infection. These symptoms can include:
- Swollen tongue
- Patches or lesions on the tongue
- Altered taste sensation
- Increased sensitivity
- Pain or burning sensation
The underlying cause of COVID tongue is still being investigated, but it’s thought to involve a combination of factors, including viral infection, inflammation, and changes in the oral microbiome.
Inflammation and Immune Response
COVID-19 triggers a systemic inflammatory response. This widespread inflammation can affect various parts of the body, including the oral cavity. The tongue, being a highly vascular and sensitive organ, can be particularly susceptible to inflammatory processes. This inflammation can manifest as swelling, redness, and pain. The body’s immune response, while crucial for fighting off the virus, can sometimes contribute to tissue damage and pain.
Nutritional Deficiencies
Illness, including COVID-19, can sometimes lead to reduced appetite and poor dietary intake. Nutritional deficiencies, particularly deficiencies in B vitamins, iron, and zinc, can manifest as oral symptoms, including tongue pain and inflammation. These deficiencies can impair the health of the oral mucosa and make the tongue more susceptible to irritation.
Medication Side Effects
Many medications used to treat COVID-19, such as antibiotics, antiviral drugs, and corticosteroids, can have side effects that affect the oral cavity. These side effects can include dry mouth, taste alterations, and increased susceptibility to oral infections. These secondary effects can indirectly contribute to tongue pain.
Opportunistic Infections
A weakened immune system, often associated with COVID-19, can increase the risk of opportunistic infections, such as oral thrush (candidiasis). Oral thrush is a fungal infection that can cause white patches on the tongue and inner cheeks, accompanied by pain and discomfort. These secondary infections can contribute to or exacerbate existing tongue pain.
Stress and Anxiety
The COVID-19 pandemic has been a source of significant stress and anxiety for many people. Stress can manifest physically in various ways, including muscle tension, teeth grinding (bruxism), and changes in saliva production. These factors can contribute to temporomandibular joint (TMJ) disorders and other conditions that can cause referred pain to the tongue. Stress can also lower the immune system and make a person more vulnerable to oral infections.
When to Seek Medical Attention
While mild tongue pain might resolve on its own, it’s essential to seek medical attention if you experience any of the following:
- Severe or persistent tongue pain that doesn’t improve with home remedies.
- Difficulty swallowing or speaking.
- Swelling of the tongue or throat.
- Red or white patches on the tongue that don’t go away.
- Fever, chills, or other signs of infection.
- Sudden onset of tongue pain, especially if accompanied by other neurological symptoms.
A healthcare professional can evaluate your symptoms, identify the underlying cause of your tongue pain, and recommend appropriate treatment.
Diagnosis and Treatment Options
Diagnosing the cause of tongue pain can involve a thorough medical history, physical examination, and possibly some diagnostic tests.
Diagnostic Procedures
A healthcare provider may perform the following diagnostic procedures:
- Oral examination: A visual inspection of the tongue and oral cavity to look for signs of inflammation, lesions, or infection.
- Medical history: A detailed review of your medical history, including any underlying health conditions, medications, and recent illnesses (like COVID-19).
- Blood tests: Blood tests can help identify nutritional deficiencies, infections, or other underlying medical conditions.
- Swab culture: A swab of the tongue can be taken to test for fungal or bacterial infections.
- Biopsy: In rare cases, a biopsy of the tongue tissue may be necessary to rule out more serious conditions.
Treatment Approaches
Treatment for tongue pain will depend on the underlying cause. Some common treatment approaches include:
- Oral hygiene: Maintaining good oral hygiene, including regular brushing and flossing, can help prevent infections and reduce inflammation.
- Topical medications: Topical pain relievers, such as benzocaine or lidocaine, can provide temporary relief from tongue pain.

Can COVID-19 directly cause tongue pain?
While a sore throat is a well-known COVID-19 symptom, direct tongue pain is less commonly reported. However, some individuals infected with COVID-19 have described experiencing a burning sensation, tingling, or general discomfort on their tongue. This pain can manifest in various ways and might be linked to inflammation affecting the nerves in the mouth or changes in taste perception triggered by the virus. Additionally, dehydration, a common symptom of COVID-19, can exacerbate existing mouth dryness and contribute to tongue discomfort.
It’s important to note that the exact mechanisms by which COVID-19 could cause tongue pain are still being investigated. The observed tongue pain may also be an indirect effect of the virus impacting other systems in the body or related to underlying conditions worsened by the infection. Therefore, while a direct link isn’t definitively established in all cases, tongue pain could potentially be a symptom associated with COVID-19, warranting medical evaluation.
What is “COVID tongue,” and how is it related to tongue pain?
“COVID tongue” is a term that gained some traction during the pandemic, referring to various changes observed on the tongue of individuals with COVID-19. These changes can include swelling, inflammation, discoloration (ranging from white patches to redness), ulcers, and a change in texture, sometimes described as a “furry” or “hairy” appearance. While not everyone with COVID-19 experiences these tongue changes, and not all cases of these tongue changes are necessarily caused by COVID-19, they are worth noting as possible associations.
These changes on the tongue, especially inflammation and ulcers, can indeed contribute to tongue pain. The presence of lesions or an altered surface texture can make the tongue more sensitive to touch, temperature, and certain foods, resulting in pain or discomfort. If you notice significant changes to your tongue along with other COVID-19 symptoms, it’s crucial to consult a healthcare professional for proper diagnosis and management.
Besides COVID-19, what other conditions can cause tongue pain?
Tongue pain is a symptom that can arise from a multitude of causes, independent of COVID-19. Some common culprits include oral thrush (a fungal infection), canker sores (small ulcers that develop inside the mouth), glossitis (inflammation of the tongue), and geographic tongue (a condition that causes patches on the tongue’s surface). Nerve damage, nutritional deficiencies (such as vitamin B12 or iron deficiency), and allergic reactions can also lead to tongue discomfort.
Furthermore, certain medications, dental procedures, and even stress or anxiety can contribute to tongue pain. Acid reflux, which can irritate the mouth and throat, is another potential cause. If you experience persistent tongue pain without other COVID-19 symptoms, exploring these alternative possibilities with your doctor is essential to identify the underlying cause and receive appropriate treatment.
What are some home remedies to relieve tongue pain associated with COVID-19 or other causes?
Several home remedies can provide temporary relief from tongue pain. Maintaining good oral hygiene by gently brushing your teeth and tongue can help prevent infection and irritation. Rinsing your mouth with warm salt water can also soothe inflammation and promote healing. Avoiding spicy, acidic, or very hot foods can prevent further irritation of the tongue.
Drinking plenty of fluids is crucial for maintaining hydration, which can alleviate dryness and discomfort in the mouth. Over-the-counter pain relievers, such as ibuprofen or acetaminophen, may help manage the pain. Additionally, sucking on ice chips or popsicles can provide a numbing effect and reduce inflammation. However, if the pain persists or worsens, seeking professional medical advice is necessary.
When should I see a doctor for tongue pain, especially if I suspect COVID-19?
It’s important to consult a doctor if your tongue pain is severe, persistent, or accompanied by other concerning symptoms. If you also experience fever, cough, shortness of breath, loss of taste or smell, or other typical COVID-19 symptoms, it’s crucial to get tested for COVID-19 and follow your doctor’s recommendations. Even if you test negative for COVID-19, medical evaluation is still necessary to determine the cause of the tongue pain.
Other warning signs that warrant medical attention include difficulty swallowing or speaking, significant changes in the appearance of your tongue (such as unusual growths or discoloration), bleeding from the tongue, or a rash on the skin along with tongue pain. These symptoms could indicate a more serious underlying condition that requires prompt diagnosis and treatment.
How is tongue pain diagnosed if it’s not clearly related to COVID-19?
Diagnosing tongue pain involves a thorough examination of your mouth and a review of your medical history. Your doctor will likely ask about the onset, duration, and characteristics of the pain, as well as any other symptoms you may be experiencing. They will also inquire about medications you’re taking, any underlying medical conditions, and your oral hygiene habits. A physical examination of the tongue and surrounding tissues will help identify any visible abnormalities.
Depending on the initial assessment, your doctor may order further tests to rule out other potential causes. These tests could include blood tests to check for nutritional deficiencies or infections, cultures to identify fungal or bacterial infections, or even a biopsy of the tongue tissue if there are suspicious lesions. In some cases, a referral to a specialist, such as an oral surgeon or ENT (ear, nose, and throat) doctor, may be necessary for further evaluation.
Is there a specific treatment for tongue pain caused by COVID-19?
There is no single, specific treatment for tongue pain directly caused by COVID-19. Treatment typically focuses on managing the underlying viral infection and alleviating the symptoms. This may involve rest, hydration, and over-the-counter pain relievers to address fever and discomfort. For tongue-specific pain, maintaining good oral hygiene and using soothing mouth rinses can provide relief. If other symptoms like taste alteration are present, they generally resolve as the body recovers from the infection.
In more severe cases, a doctor might prescribe antiviral medications to combat the COVID-19 infection. If secondary infections arise, such as oral thrush, antifungal medications may be necessary. Ultimately, the best approach is to consult with a healthcare professional to develop an individualized treatment plan that addresses both the COVID-19 infection and any associated tongue pain or oral symptoms. They can also provide guidance on managing symptoms and preventing complications.
