Apart from loss of taste, look out for oral symptoms of Covid-19

Losing a sense of smell and taste can be one of the most sure symptoms of coronavirus and can take weeks to fully heal. As per studies, the sign is reported in more than 60% of COVID+ cases.

However, that may not be the ONLY way the SARS-COV-2 virus affects and alters your tastebuds. With researches and case studies constantly being brought forward, we are only beginning to learn the multitude of ways the virus wrecks havoc on the human body and impairs vital senses as well.

According to a new study conducted by the National Institute of Health (NIH), which has been published in the scientific journal, Nature Medicine, nearly half of Covid victims suffer from oral symptoms during the course of the infection.

Dry mouth

Dry mouth syndrome is usually connected to a lot of viral infections, autoimmune disorders and now, COVID-19 as well.

Experiencing a dry mouth basically means that the mouth goes through a tough time producing saliva, which keeps your mouth lubricated, aids digestion and most importantly, keeps the mouth protected against bad bacteria and other pathogens. A dry mouth can make you feel a sense of dryness or stickiness in the mouth and further, make the saliva a little thicker.

Having bad breath is also sometimes a common sign of dry mouth. It can also induce difficulties in chewing food, speaking and make you experience a harsh, burning sensation at the roof of your mouth. Unusual symptoms such as these, right now, need to be checked out at once.


When you go through a viral infection like COVID-19, one of the typical sensations you could experience is widespread inflammation, when the virus attacks muscle fibres, organ linings. This inflammation can show up in the form of lesions, painful bumps, including on the tongue and gum areas.

For some people, a viral infection in the mouth could also come up in the form of ulcers, irritations and allergies. While there’s no proven way to combat these lesions, experiencing painful bumps could put you off eating and avoid some food.

COVID tongue

COVID tongue is a much-discussed viral symptom right now. While there’s no exact reason we know right now as to what causes it, a virus like SARS-COV-2 could definitely impact your tongue. For one, according to a lot of case studies, experiencing a COVID tongue can be quite arduous. Patients also experience a burning sensation and inflammation on the surface of the tongue. Some doctors also agree that COVID tongue sensation could be linked to the skin rashes which have come to be associated with COVID-19.

Changes to the colour/ sensation of the tongue

Another way COVID-19 could impact the oral cavities, and most particularly, the tongue is by altering the colour and texture of the tongue.

Mouth irritation, swelling and multiplication of the pathogen near your oral cavities can make your tongue feel weird. It can also cause mouth irritation, make your lips, tongue tingle or feel a lot more irritated than it usually should be.

Do not ignore any symptoms

Do remember that changes in the mouth and tongue aren’t precise COVID-19 symptoms right now, and may not affect everyone. However, with the changing behaviour of the virus and a rise in cases, any symptoms and sudden, unusual symptoms are worth getting checked. Consider getting a test done at the earliest if you experience unusual changes or experience other COVID symptoms. Quarantine, isolate as needed and get help.             —Times of India
