Metallic Taste in Mouth Post COVID-19

Do you feel taste like old pennies in your mouth? This condition is known as Dysgeusia or parageusia. Covid-19 causes a change in your sense of taste such as metal mouth that can be an indication of a variety of medical issues.

Metallic taste in mouth, also known as dysgeusia can be a symptom of COVID-19. This is a taste disorder that tends to last longer than other symptoms. Alike, respiratory infections such as the common cold can also leave people with a metallic taste. SARS-CoV-2-Vaccine also leads to metallic taste hours to week after the vaccination apart from COVID-19 infection. SARS-CoV-2 Vaccinations also induce transient symptoms including muscle aches or fevers.

People commonly might develop a metal taste immediately after receiving the COVID-19 vaccine and mainly it is no reason to be concerned. This is a benign side effect that resolves on its own within a day or two and is usually rare.

If you develop a loss of smell, loss of taste, or if these symptoms begin a day or two after your shot, then see a doctor. A loss of smell or taste after vaccination is mostly due to COVID-19 infection.

Symptoms of COVID-19 & Metallic Taste in Mouth

COVID-19 is a viral infection caused by coronavirus, which can cause a wide range of flu-like symptoms 2 to 14 days after exposure.

People with this condition also might have it in tandem with burning mouth syndrome , where your mouth has a burning sensation that causes pain.

Typically, metal mouth resolves itself once the underlying cause has been treated, but a COVID-19-induced metallic taste in the mouth could stick around for weeks or even months after your recovery from the virus.

Cause of Metallic Taste in Mouth

Taste is one of the important part of the five senses. Taste would involve several neurological functions. There could be various reasons for metallic taste on mouth, such as coronavirus infection. During Covid-19 infection the perception of taste could be due to the innate immune system.

For some people the metallic taste results from the zinc absorption being affected by other drugs. A low zinc level can also cause the metallic taste. For other people, the cause of metallic taste is idiopathic. Some of the rare reasons include:

  • Medication-induced changes in saliva production,
  • Presence of the drug in your saliva,
  • Changes in normal cell function,

  • Infection, and
  • Changes to the nervous system.

If the metallic taste is because of COVID-19 the doctor would run a test to confirm the diagnosis.
