Overview
Mouth Ulcer
A mouth ulcer is a small, painful sore that develops on the lining of the mouth, including the inside of the lips or cheeks, tongue, gums, or other soft tissues. Many mouth ulcers are minor and heal on their own within one to two weeks. They can be triggered by accidental injury, irritation, stress, illness, or nutritional deficiencies. Persistent or unusual ulcers require dental or medical assessment.
COVID-19
COVID-19 is an illness caused by the coronavirus SARS-CoV-2. It spreads mainly when an infected person breathes out respiratory droplets and very small particles containing the virus. Illness can range from mild to severe, and some people develop complications or longer-lasting symptoms after the initial infection. Testing, vaccination, and appropriate medical care are important parts of prevention and management.

Mouth Ulcer
Most mouth ulcers are diagnosed by examining the sore and reviewing the person’s history. A clinician or dentist may assess its size, location, appearance, duration, and recurrence. Testing is generally unnecessary for a typical short-lived ulcer. Blood tests or other investigations may be considered when ulcers are frequent, severe, persistent, associated with other symptoms, or suggest an underlying nutritional or systemic condition.
COVID-19
COVID-19 is diagnosed using tests that detect SARS-CoV-2 infection. Testing may be recommended when symptoms develop or after an appropriate exposure, depending on the situation. Common symptoms can include fever, cough, tiredness, sore throat, congestion, and changes in taste or smell, although symptoms vary. Healthcare providers consider symptoms, exposure history, and test results when evaluating illness.
Prevention
Mouth Ulcer
Some mouth ulcers cannot be completely prevented, but avoiding known triggers may reduce recurrences. Protect the mouth from injury, maintain good oral hygiene, and use care when eating very hot or hard foods. Dental problems and poorly fitting appliances should be corrected. A balanced diet helps prevent nutritional deficiencies. Seek evaluation for ulcers that do not heal within a reasonable period or repeatedly return.
COVID-19
COVID-19 risk can be reduced by staying up to date with recommended vaccines, improving indoor ventilation, and avoiding close contact with people known to be infected. Staying home when sick and following current public-health guidance can reduce transmission. People at higher risk of severe disease should discuss prevention and early treatment options with their healthcare provider.
Risk Factors
Mouth Ulcer
Risk factors include previous mouth ulcers, accidental biting or other oral injury, dental appliances, sharp teeth, emotional stress, hormonal changes, and nutritional deficiencies. Certain medicines and foods may trigger ulcers in susceptible people. Poorly fitting dentures and other sources of repeated irritation can also increase the chance of developing sores.
COVID-19
The risk of severe COVID-19 increases with older age and certain underlying medical conditions. Risk can also be affected by immune-system problems and other factors that make it harder for the body to fight infection. Previous vaccination or infection can provide protection against severe disease, although protection changes over time. Exposure to an infected person increases the chance of becoming infected.
