Roof of Mouth Soreness as a New COVID Symptom with Omicron

Roof of Mouth Hurts: Could It Be a COVID Symptom?

As the COVID-19 pandemic continues to evolve, researchers have noticed that the common symptoms associated with the virus seem to be changing as well. While the original and delta variants were associated with loss of taste and smell, the latest data shows this may no longer be the case. One symptom that seems to be more prevalent with the omicron variant is a sore roof of the mouth.

Examining the Changing COVID Symptoms

A recent study published in May 2022 examined the most common COVID-19 symptoms among people infected with the omicron variant. Researchers used data from the Zoe COVID Study app, where people self-report their COVID symptoms. The analysis included symptoms from over 63,000 COVID positive cases from December 2021 to March 2022 in the UK, when omicron was the dominant strain.

Researchers found that the top 5 symptoms for omicron infection were:

1. Sore throat
2. Runny nose
3. Headache
4. Fatigue
5. Sneezing

Two hallmark symptoms of earlier variants, loss of smell and loss of taste, were much less common with omicron. Previously, these symptoms were in the top 10 for COVID illness, but now they rank outside the top 20 most reported symptoms.

Why Are COVID Symptoms Changing?

Researchers believe there are a few reasons why omicron symptoms seem to differ from earlier variants:

• Omicron has over 50 genetic mutations, which alter the behavior of the virus.
• Omicron replicates faster in the upper respiratory tract (nose, mouth, throat) rather than the lungs, leading to more upper respiratory symptoms.
• Previous variants may have spread to olfactory nerve endings responsible for loss of smell more readily than omicron does.

Understanding the most common symptoms associated with the current dominant variant can help individuals recognize if they should isolate and get tested for COVID-19.

How a Sore Roof of Mouth May Relate to COVID

The roof of the mouth, known medically as the palate, may become sore for a variety of reasons. Some potential causes include:

• Allergies
• Common cold
• Strep throat
• Oral thrush
• Canker sores
• Injury from hot foods

During the omicron wave, many people reported a sore or scratchy throat as a common early COVID symptom. A sore palate can accompany a sore throat.

How Omicron May Cause a Sore Roof of Mouth

Here are some theories as to why omicron may specifically cause pain in the roof of the mouth for some people:

• The rapid replication of omicron in the nose, mouth and throat can cause inflammation and irritation throughout the upper respiratory tract.
• Lymph nodes in the neck and throat may become swollen as the body fights off the virus. This throat swelling may radiate up to the palate.
• Omicron viruses attach to cells lining the throat and palate, causing lesions and discomfort known as oral thrush.
• Sneezing and coughing from COVID can result in a raw, sore palate.

Other COVID Symptoms Linked to Sore Palate

Along with a sore throat, here are some other COVID symptoms that may accompany a painful palate:

• Runny nose - nasal discharge can cause irritation as it drips down the throat.
• Nasal congestion - swollen nasal passages combined with mouth-breathing at night can dry out and inflame the palate.
• Fever and chills - these indicate an active immune response that may also cause body aches.
• Cough and sneezing - repeated irritation of the throat from coughing can make the palate sore.
• Fatigue and headache - potential signs of viral infection taxing the body.

While a sore palate alone is not definitive proof of a COVID infection, it warrants attention when combined with other symptoms of the virus.

Getting an Accurate COVID Diagnosis

Because omicron symptoms can mimic other respiratory viruses and conditions, testing is important to confirm a COVID-19 infection. There are a few testing options available:

PCR Tests

The PCR test is considered the gold standard for COVID-19 diagnosis. This lab test detects genetic material from the SARS-CoV-2 virus through a nasal swab sample. Results take 1-3 days.

Rapid Antigen Tests

Rapid antigen tests quickly detect COVID viral proteins through a nasal swab. Results are available in 10-30 minutes. Rapid tests may miss some omicron infections, so a PCR test for confirmation may be recommended.

At-Home Tests

There are many at-home rapid COVID tests now available over-the-counter. Popular options include BinaxNOW, iHealth, Flowflex, InteliSwab, and more. At-home tests provide quick results but are not as sensitive as lab PCR tests.

Consult your doctor if you are unsure which COVID test is right for your situation and symptoms.

Treatment Options for Sore Palate Pain Relief

Whether due to COVID or other causes, a number of home remedies and over-the-counter medications can provide relief for a sore roof of mouth. Some options include:

Saltwater Rinses and Gargles

Rinsing with warm saltwater can help reduce oral inflammation and soothing irritation. Dissolve 12 teaspoon salt in a cup of warm water and rinse several times a day.

Throat Lozenges and Sprays

Cough drops, throat sprays, and oral anesthetics containing ingredients like phenol, benzocaine, and menthol can temporarily numb roof of mouth discomfort.

OTC Pain Relievers

Medications like acetaminophen, ibuprofen, and naproxen sodium can reduce sore throat and palate pain and swelling.

Cold Foods and Beverages

Sucking on ice chips, popsicles, frozen fruit, or cold beverages can calm oral pain and inflammation.

Avoid spicy, acidic, crunchy, or abrasive foods that may further irritate the palate while it heals. Soft, cool foods are ideal.

Hydrogen Peroxide and Honey

These have natural antimicrobial effects that can aid recovery. Mix 1 tablespoon honey with 14 cup warm water and a small splash of hydrogen peroxide. Swish gently for 30 seconds before swallowing.

Be sure to get adequate rest and stay hydrated as well while recovering. If roof of mouth pain persists or worsens, see your doctor to rule out complications like sinusitis, tonsillitis, or oral infections.

Preventing Viral Infections Including COVID-19

Practicing healthy habits can help lower your risk of developing a painful sore throat and mouth pain from COVID-19 and other viruses.

• Get vaccinated and stay up-to-date on recommended COVID boosters.
• Wash hands frequently with soap and water.
• Use alcohol-based hand sanitizer when soap is unavailable.
• Avoid close contact with sick individuals.
• Don't touch your face, eyes, nose or mouth with unwashed hands.
• Wear a high-quality mask in crowded public settings.
• Clean and disinfect frequently touched surfaces.
• Get adequate sleep and stay hydrated.

While COVID cases associated with omicron continue to climb, understanding the most common symptomslike a scratchy sore throat and mouthis key. This can ensure prompt testing and care when needed. Consult your doctor with any specific questions or concerns about symptoms you may be experiencing.
