It’s probably never good to have a “rash” of anything in your life except maybe bacon, and even in that context, your cardiologist might want to have a word of culinary caution with you.
While bacon at breakfast may leave a good taste in most mouths, looking in the mirror in the morning and finding a rash in your mouth is certain to have the opposite effect.
And let’s face it, with the COVID-19 pandemic over the past two years, most of us have had enough anxiety for a lifetime so we do not need to be wondering … “Why do I have a rash in my mouth?”
The good news is that most rashes in your mouth are caused by irritants such as poorly fitting dentures, dental devices such as braces and retainers, sharp or broken teeth, tobacco products, or even damage from hot food or beverages.
It’s often not easy to pinpoint the cause of mouth irritation because, in addition to what was mentioned above, there are many other causes of mouth sores or rashes, including:
Women can be even more susceptible to mouth rashes than men with hormonal changes during pregnancy causing them.
Another thing that can cause a rash in your mouth: Stress!
This, of course, can be a destructive circle because the discovery of a rash in your mouth can often lead to more stress.
Speaking of stress, during the pandemic it has become a habit to associate any unusual symptoms with the possibility of the onset of the COVID-19 virus.
And some have attributed mouth rash as another in a long line of COVID-19 symptoms.
“While rashes on the skin have long been tied to COVID-19, doctors in Spain report that rashes on the inside of the mouth are also occurring in some cases,” reported Brigham and Women’s Hospital.
The rashes in the case of coronavirus are known as enanthem.
“An enanthem is a rash [small spots] on the mucous membranes," explained Dr. Michele Green, who practices at Lenox Hill Hospital in New York City, to Health Day News. "It is very common in patients with viral infections like chickenpox and hand, foot, and mouth disease. It is characteristic of many viral rashes to affect mucous membranes."
The Spanish study looked at 666 patients with COVID-19 and found almost half (304) had mucocutaneous manifestations (visual markers in assessing a viral infection) including 25.7 percent (78 cases) with some sort of rash in their oral cavity or mouth.
According to Brigham and Women’s Hospital “the mouth rash appeared anywhere from two days before the onset of other COVID symptoms to 24 days after, with an average time of about 12 days after onset of symptoms.”
COVID-19 is not the only medical condition that can cause a rash or sores in your mouth.
According to Medical News Today, diseases and medical conditions that can cause mouth sores to include:
“When in doubt, you can be examined by your dentist, doctor, or oral surgeon. They may perform a blood test or even biopsy the area to test for the presence of cancer or other health issues,” says Dr. Stephen C. Dwyer of Northwest Oral and Maxillofacial Surgery.
In many cases, your mouth rash will disappear as fast as it appeared, often clearing up within a week or two.
Some tips to treat your mouth rash at home include:
If your mouth rash does not clear up, then a visit to your dentist or doctor is in order and they will be able to help identify what is causing your mouth rash and to prescribe a treatment plan including prescribing anti-inflammatory and/or pain-relieving medications.
For sure, make a healthcare appointment if you have any of the following signs:
“Remember, most rashes in your mouth have benign causes, but if you get frequent mouth rashes, or have a mouth rash that is getting worse or causing you concern, then reach out to a healthcare professional today,” said Dr. Dwyer.
