Understanding Mouth Sores: What Are They?
Mouth sores, also known as oral lesions, are painful or uncomfortable areas that appear on the mucous membranes inside the mouth. They can take various forms, including canker sores (aphthous ulcers), cold sores (caused by herpes simplex virus), and other ulcerations or erosions. Mouth sores can result from a variety of causes such as viral infections, trauma, nutritional deficiencies, autoimmune diseases, and allergic reactions.

COVID-19 and Oral Symptoms: What Does the Evidence Say?
From the early stages of the pandemic, clinicians observed that some COVID-19 patients developed unusual symptoms beyond the typical respiratory issues.
Notably, oral manifestations have been reported in a subset of people infected with SARS-CoV-2.
- Loss of Taste and Smell: One of the most common oral-related symptoms is a sudden loss or alteration in taste (ageusia or dysgeusia). This is believed to be caused by the virus’s impact on sensory nerves and cells in the oral and nasal cavities.
- Dry Mouth (Xerostomia): Many COVID-19 patients report dry mouth, which can contribute to discomfort and make the oral environment more susceptible to infections.
- Oral Lesions and Sores: Various studies have documented the presence of mouth sores, ulcers, and other lesions in COVID-19 patients. These lesions have been described as painful ulcers, blisters, erosions, and erythematous (red) areas.
How Common Are Mouth Sores in COVID-19 Patients?
The exact prevalence of mouth sores among COVID-19 patients remains unclear due to differences in study designs and patient populations. However, some research provides insight:
- A study published in the Journal of Medical Virology reported that approximately 10-15% of COVID-19 patients experienced oral lesions.
- Other case reports have highlighted patients presenting with painful ulcers on the tongue, palate, and inner cheeks during or shortly after COVID-19 infection.
It’s important to note that these symptoms are not universal, and many patients with COVID-19 never develop any oral lesions.

Possible Mechanisms: Why Does COVID-19 Cause Mouth Sores?
Several theories attempt to explain why COVID-19 might lead to the development of mouth sores:
- Direct Viral Infection: SARS-CoV-2 uses the ACE2 receptor to enter human cells. These receptors are abundantly present in oral mucosal tissues, such as the tongue and salivary glands. This suggests that the virus might directly infect cells in the mouth, causing localized damage and sores.
- Immune Response and Inflammation: COVID-19 triggers a strong immune response. In some cases, excessive inflammation (a “cytokine storm”) might damage the oral mucosa, resulting in ulcerations.
- Secondary Infections: The immunosuppression or immune dysregulation caused by the virus may make patients more vulnerable to secondary infections, such as fungal or bacterial infections, which can cause mouth sores.
- Stress and Systemic Effects: The physical and psychological stress associated with COVID-19 illness may contribute to the development of canker sores or exacerbate pre-existing oral conditions.
- Medication Side Effects: Treatments used to manage COVID-19 symptoms, including certain antivirals and antibiotics, may have side effects that include mouth irritation or sores.

Diagnosing Mouth Sores in the Context of COVID-19
Because mouth sores can have many causes, it is essential for healthcare providers to carefully assess patients presenting with oral lesions during or after COVID-19 infection. The diagnosis involves:
- Clinical examination of the mouth to characterize the size, location, and appearance of the sores.
- Reviewing the patient’s medical history, including COVID-19 status and any medications.
- Considering other possible causes such as herpes simplex virus, nutritional deficiencies, or autoimmune disorders.
In some cases, biopsies or laboratory tests may be necessary to rule out other conditions.

Management and Treatment of COVID-19-Related Mouth Sores
COVID-19, caused by the SARS-CoV-2 virus, is primarily known for its respiratory symptoms; however, it has become evident that the virus can also manifest with a range of oral symptoms, including mouth sores.
These oral lesions, which may include ulcers, blisters, and mucosal inflammation, can cause significant discomfort and impact a patient’s quality of life. Effective management of COVID-19- related mouth sores requires a comprehensive approach that addresses symptom relief, promotes healing, and considers the underlying viral infection.
Understanding COVID-19-Related Mouth Sores
Oral lesions associated with COVID-19 appear to result from a combination of factors including direct viral impact on oral mucosa, immune system dysregulation, secondary infections, and systemic inflammation. Common presentations include aphthous-like ulcers, herpetiform lesions, and erythematous patches. These sores can be painful, making eating, drinking, and speaking difficult for patients.
Assessment and Diagnosis
Healthcare providers should conduct a thorough oral examination for patients with COVID-19 who report oral discomfort. Differentiating COVID-19-related lesions from other causes, such as herpes simplex virus infection, aphthous stomatitis, or drug reactions, is important. A detailed medical history including recent medication use, comorbidities, and symptom timeline aids in accurate diagnosis.
Management Strategies
Symptomatic Relief:
- Topical Analgesics: Application of topical agents such as benzocaine gels or lidocaine rinses can provide temporary pain relief.
- Anti-inflammatory Mouthwashes: Mouth rinses containing corticosteroids (e.g., dexamethasone) or non-steroidal anti-inflammatory agents may reduce mucosal inflammation.
- Antiseptic Rinses: Chlorhexidine gluconate mouthwash can help minimize secondary bacterial infections and promote healing.
Promoting Healing:
- Maintain Oral Hygiene: Encouraging patients to maintain gentle but effective oral hygiene reduces the risk of secondary infection.
- Nutritional Support: Ensuring adequate hydration and a balanced diet, possibly with soft foods, aids tissue repair.
- Avoid Irritants: Patients should avoid spicy, acidic, or rough-textured foods that can exacerbate mucosal irritation.
Addressing Underlying Causes:
- Antiviral Therapy: While specific antiviral treatments for COVID-19 mouth sores are not established, managing the systemic viral infection may indirectly improve oral symptoms.
- Immune Modulation: In cases where immune dysregulation contributes, corticosteroids prescribed systemically or topically under medical supervision may be beneficial.
- Management of Secondary Infections: If bacterial or fungal infections complicate mouth sores, appropriate antimicrobial therapy should be initiated.
Monitoring and Referral:
Patients with persistent, worsening, or atypical oral lesions should be referred to specialists such as oral medicine experts or infectious disease clinicians for further evaluation and management.
Preventive Measures
For individuals at risk, preventive strategies include maintaining excellent oral hygiene, avoiding tobacco and alcohol, managing underlying systemic illnesses, and following COVID-19 preventive protocols to reduce infection risk.
Conclusion
Mouth sores related to COVID-19, while often self-limiting, require attentive management to alleviate symptoms and prevent complications.
A multidisciplinary approach involving symptom control, promotion of healing, and treatment of underlying factors ensures optimal patient outcomes.
As research evolves, clearer guidelines on targeted therapies for COVID-19-associated oral lesions are anticipated, underscoring the importance of ongoing clinical vigilance and patient education.
