Is Your Tongue Sore? It Could Be a COVID-19 Symptom

While COVID-19 is commonly associated with respiratory symptoms, the virus can also affect other parts of the body, including the mouth. Some people experience unusual symptoms like a burning sensation or pain on the tongue, which can be uncomfortable, especially when eating. In this article, we’ll explore how COVID-19 can impact the mouth and tongue, what might cause these symptoms, and what steps you can take to manage the discomfort.

Is Your Tongue Sore? It Could Be a COVID-19 Symptom


COVID-19 and Oral Symptoms: An Overview

COVID-19 is primarily known for its respiratory symptoms, such as cough, fever, and shortness of breath. However, as the pandemic has progressed, it has become clear that the virus can also cause a wide range of other symptoms, some of which are less commonly discussed. These can include gastrointestinal issues, skin rashes, and importantly, oral symptoms.

One of the less well-known symptoms is discomfort or pain in the mouth, specifically on the tongue. This can manifest as a burning sensation, similar to what you might feel after eating something too hot, or a general soreness that makes eating and speaking uncomfortable.


Common Oral Symptoms of COVID-19

As research into COVID-19 continues, healthcare professionals have identified several oral symptoms that can be associated with the virus: 

  1. Loss of Taste (Ageusia) or Altered Taste (Dysgeusia): One of the hallmark symptoms of COVID-19 is the sudden loss or alteration of taste. This can range from a complete inability to taste to experiencing unusual or distorted tastes.
  2. Oral Ulcers and Lesions: Some COVID-19 patients develop painful ulcers or sores in the mouth, including on the tongue. These can resemble canker sores and may cause significant discomfort.
  3. Tongue Pain or Burning Sensation: Another symptom reported by some COVID-19 patients is a burning or stinging sensation on the tongue. This can feel similar to burning your tongue on hot food or drink and can make eating and speaking painful.
  4. Dry Mouth (Xerostomia): COVID-19 can also lead to dry mouth, which can exacerbate oral discomfort. Dry mouth can make the tongue feel rough and sensitive, and can contribute to the development of oral ulcers.

Why Does COVID-19 Affect the Mouth?

The exact mechanisms by which COVID-19 affects the mouth and tongue are still being studied, but several theories have been proposed: 

  1. Viral Infection of Oral Tissues: The virus that causes COVID-19, SARS-CoV-2, enters cells by binding to a receptor called ACE2, which is found in various tissues throughout the body, including in the mouth. It’s possible that the virus directly infects the cells in the mouth and tongue, leading to inflammation and pain.
  2. Immune Response: The body’s immune response to the virus can cause widespread inflammation, which might affect the mouth. This inflammation could contribute to symptoms like oral ulcers or a burning sensation on the tongue.
  3. Dry Mouth: COVID-19 can cause dry mouth either as a direct symptom or as a side effect of medications used to treat the virus. A dry mouth lacks the saliva necessary to keep the mouth moist and comfortable, leading to irritation and discomfort.
  4. Nutritional Deficiencies: Some COVID-19 patients may experience a reduced appetite or difficulty eating due to symptoms like loss of taste, leading to nutritional deficiencies. Deficiencies in certain vitamins, such as B vitamins or zinc, can contribute to oral symptoms like soreness or burning.

Managing COVID-19-Related Tongue Pain and Discomfort

If you’re experiencing tongue pain or a burning sensation due to COVID-19, there are several steps you can take to manage the discomfort: 

  1. Rinse with Salt Water: Gargling with a warm saltwater solution can help soothe the tongue and reduce inflammation. Mix half a teaspoon of salt in a glass of warm water and swish it around your mouth for 15-30 seconds before spitting it out. This can be done several times a day.
  2. Stay Hydrated: Drinking plenty of water is crucial, especially if you’re dealing with dry mouth. Staying hydrated can help maintain saliva production and reduce irritation on the tongue.
  3. Avoid Irritating Foods: While your tongue is sore, try to avoid foods that can irritate it further. This includes spicy foods, acidic foods like citrus fruits, and crunchy foods that can scratch the surface of the tongue.
  4. Eat Soft, Bland Foods: Stick to soft foods that are easy to chew and swallow, such as mashed potatoes, yogurt, smoothies, and soups. These foods are less likely to cause discomfort when your tongue is sensitive.
  5. Use Over-the-Counter Pain Relief: If the pain is significant, over-the-counter pain relievers like acetaminophen (Tylenol) or ibuprofen (Advil) may help reduce discomfort. However, it’s important to use these medications as directed and consult with a healthcare provider if you have any concerns.
  6. Avoid Tobacco and Alcohol: Smoking and drinking alcohol can further irritate the mouth and slow down the healing process. It’s best to avoid these substances until your symptoms have resolved.

When to See a Doctor

While many oral symptoms related to COVID-19 are mild and will resolve on their own as you recover from the virus, there are situations where you should seek medical attention: 

  1. Severe or Persistent Pain: If the pain in your tongue or mouth is severe, doesn’t improve with home care, or gets worse over time, it’s important to consult with a healthcare provider. They can check for any underlying issues that may need specific treatment.
  2. Difficulty Eating or Drinking: If your oral symptoms are so severe that you’re unable to eat or drink properly, you should seek medical advice. Dehydration and malnutrition can be serious concerns, especially when you’re already dealing with COVID-19.
  3. Signs of Infection: If you notice signs of an infection in your mouth, such as increased swelling, redness, pus, or a fever, it’s important to seek medical attention promptly. These could be signs of a secondary bacterial infection that requires treatment.
  4. Persistent Loss of Taste or Smell: While it’s common for COVID-19 patients to lose their sense of taste or smell, these symptoms should gradually improve as you recover. If they persist for weeks or months after your other symptoms have resolved, it’s a good idea to discuss this with your doctor.

The Importance of Oral Health During COVID-19

Maintaining good oral hygiene is important, especially when you’re sick. COVID-19 can weaken your immune system, making you more susceptible to other infections, including those in your mouth. Here are some tips to help keep your mouth healthy during your recovery:

  1. Brush and Floss Regularly: Continue to brush your teeth at least twice a day and floss daily to remove food particles and plaque that can contribute to oral health issues.
  2. Use an Antimicrobial Mouthwash: Using a mouthwash can help reduce bacteria in your mouth and prevent infections, especially if you’re dealing with dry mouth.
  3. Avoid Sharing Utensils or Personal Items: If you live with others, be mindful not to share eating utensils, drinking glasses, or toothbrushes to reduce the risk of spreading the virus.
  4. Stay on Top of Your Overall Health: Eating a balanced diet, staying hydrated, and getting enough rest are all important for your recovery from COVID-19 and for maintaining good oral health.

Conclusion

While it’s less commonly discussed, oral symptoms like tongue pain or a burning sensation can be part of the COVID-19 experience. If you’re dealing with these symptoms, taking steps to soothe your mouth and avoid further irritation can make a big difference in your comfort level. Most importantly, if your symptoms are severe or not improving, don’t hesitate to reach out to a healthcare professional for advice. As with any illness, paying attention to your body and taking proactive steps to manage your health will help you recover more smoothly.
