Wondering if those painful mouth sores could signal COVID-19/ Are mouth sores a symptom of covid ? Discover the surprising connection between mouth ulcers and the virus — and what you need to watch for to stay safe!
So , what do you think .?- Are mouth sores a symptom of covid.?
Since the emergence of COVID-19 in late 2019, the scientific and medical communities have worked tirelessly to understand the wide array of symptoms associated with this novel virus.
While respiratory symptoms such as cough, fever, and shortness of breath have been the most commonly reported, other less typical symptoms have also surfaced, including those affecting the oral cavity.
One such symptom that has raised questions is the appearance of mouth sores during or after COVID-19 infection.
This article explores whether mouth sores are a symptom of COVID-19, the possible causes behind them, and the implications for diagnosis and treatment.
What Are Mouth Sores?
Mouth sores are painful lesions or ulcers that develop on the mucous membranes inside the mouth, including the tongue, gums, inner cheeks, and palate.
They can appear as white, red, or yellow spots surrounded by inflamed tissue. Common types include:
- Aphthous ulcers (canker sores): Small, shallow, and painful ulcers that typically heal within one to two weeks.
- Herpetic stomatitis: Caused by the herpes simplex virus, these sores may be accompanied by systemic symptoms like fever.
- Traumatic ulcers: Result from injury to the mouth lining.
- Other causes: Including fungal infections, autoimmune conditions, nutritional deficiencies, and reactions to medications.

Mouth Sores and COVID-19: What Does the Research Say?
The link between mouth sores and COVID-19 has been a subject of growing investigation.
Early in the pandemic, these symptoms were not widely recognized or reported.
However, as more patients were studied, some reports indicated that a subset of COVID-19 patients experienced oral manifestations, including ulcers and other mucosal lesions.
Prevalence and Presentation -Are mouth sores a symptom of covid ?
A number of case reports and small-scale studies have noted the presence of oral ulcers in COVID-19 patients. These sores often presented alongside other symptoms such as:
- Loss of taste or altered taste sensation (ageusia or dysgeusia)
- Dry mouth (xerostomia)
- Red or swollen tongue
- Burning sensations
The sores themselves varied in appearance, sometimes resembling aphthous ulcers, other times showing characteristics similar to herpetic lesions.
The prevalence of mouth sores in COVID-19 patients varies among studies, but estimates suggest that between 5% and 15% of individuals may experience oral manifestations.
Possible Mechanisms
Several theories have been proposed to explain why mouth sores may develop in the context of COVID-19:
- Direct Viral Infection:
The SARS-CoV-2 virus enters human cells via the ACE2 receptor, which is expressed not only in the respiratory tract but also in oral mucosal tissues. This suggests that the virus could directly infect cells in the mouth, leading to inflammation and ulceration. - Immune Response and Inflammation:
COVID-19 triggers an immune response, sometimes causing an exaggerated inflammatory reaction known as a cytokine storm. This heightened immune activity can damage tissues, including the mucous membranes of the mouth, leading to sores. - Secondary Infections:
The virus may weaken the immune system, making patients more susceptible to secondary infections such as herpes simplex virus reactivation or candidiasis (fungal infection), both of which can cause oral sores. - Medication Side Effects:
Treatments used for COVID-19, such as antiviral drugs, antibiotics, or steroids, may also contribute to the development of mouth sores as adverse effects. - Stress and Nutritional Deficiencies:
The stress of illness and hospitalization, combined with poor nutrition or dehydration, may also predispose patients to developing mouth ulcers.
Differentiating COVID-19 Related Mouth Sores from Other Causes
Because mouth sores can arise from many conditions, it is important to evaluate them carefully in the context of COVID-19.
Factors to consider include:
- The timing of the sores in relation to other COVID-19 symptoms
- Presence of systemic symptoms such as fever and respiratory problems
- Patient history, including previous episodes of oral ulcers or herpes.
- Medication history and potential side effects
- Laboratory tests if needed to rule out other infections or conditions
Implications for Patients and Healthcare Providers
For Patients –
For patients experiencing mouth sores during or after COVID-19 infection, the following points are important:
- Seek medical evaluation:
While mouth sores are often benign and self-limiting, they can be painful and interfere with eating and speaking. Persistent or severe sores require professional assessment.
- Maintain oral hygiene:
Gentle cleaning of the mouth and avoiding irritants such as spicy or acidic foods can help alleviate symptoms.
- Use symptomatic treatments: Over-the-counter topical gels or mouth rinses may reduce pain and inflammation.
- Monitor for secondary infections: If sores worsen or do not heal, further evaluation for other infections may be necessary.
Implications for healthcare providers include:
Mouth sores can be an occasional symptom observed in some COVID-19 patients, though they are not among the most common or defining signs of the infection.
For healthcare providers, it’s important to recognize that while COVID-19 primarily affects the respiratory system, it can also manifest with diverse symptoms, including oral lesions such as mouth sores, ulcers, or blisters.
These may result from the virus itself, secondary infections, immune responses, or as side effects of treatments
- Differential Diagnosis: Mouth sores should prompt consideration of COVID-19 in the broader clinical context, especially if accompanied by other symptoms like fever, cough, or loss of taste and smell. Providers should also rule out other causes such as herpes simplex virus, aphthous ulcers, or medication reactions.
- Infection Control: Recognizing oral symptoms linked to COVID-19 can aid early identification and appropriate isolation measures to prevent transmission.
- Patient Management: Addressing mouth sores can improve patient comfort and nutrition; providers may consider supportive treatments and monitor for secondary infections.
- Documentation and Reporting: Providers should document oral manifestations to contribute to the evolving understanding of COVID-19’s clinical spectrum.
In summary, while mouth sores are not a hallmark symptom of COVID-19, their presence warrants attention within a comprehensive assessment to ensure accurate diagnosis and effective patient care.
