Oral shingles, also known as herpes zoster or shingles affecting the mouth area, is a condition caused by the varicella-zoster virus. This virus is the same one that causes chickenpox. After chickenpox heals, the virus can remain dormant in the body for years. Later, it can reactivate as shingles, which may affect the skin and, in some cases, the mouth.
In this article, we will explore how oral shingles develop, the symptoms to watch for, risk factors, and treatment options to help you understand and manage the condition.
What Is Oral Shingles?
Oral shingles is a viral infection that occurs when the varicella-zoster virus reactivates after being dormant in the body. It primarily affects the nerve tissue and can cause painful, blistering rashes around the mouth, gums, tongue, and inside the cheeks. It is less common than shingles on the body but can be equally uncomfortable.
When the virus reactivates, it travels along the nerves to the skin or mucous membranes. The infection can cause not only physical discomfort but also complications if not properly treated.
Causes of Oral Shingles
The varicella-zoster virus (VZV) is responsible for both chickenpox and shingles. After a person recovers from chickenpox, the virus remains in their body, specifically in nerve cells near the spinal cord. This virus can remain dormant for many years and may reactivate due to various triggers.
When the virus reactivates, it can cause shingles, which often results in a painful rash and blisters. In cases where the rash and blisters appear in the mouth or around the mouth, it is referred to as oral shingles.
The exact cause of why the virus reactivates in certain individuals is still not fully understood. However, there are several factors that increase the likelihood of developing oral shingles.
How Is Oral Shingles Transmitted?
Oral shingles is caused by the same virus that causes chickenpox. However, shingles itself is not directly contagious. You cannot catch shingles by coming into contact with someone who has it. However, the varicella-zoster virus is highly contagious during the initial stages of a chickenpox infection.
If you have never had chickenpox or received the chickenpox vaccine, you can contract the varicella-zoster virus by coming into contact with the fluid from the blisters of a person with active shingles. This can lead to chickenpox rather than shingles, especially in young children or people with weak immune systems.
Once you have had chickenpox, the virus remains dormant in your body. It can reactivate years later, causing shingles. Therefore, oral shingles results from the reactivation of the virus that was already present in the body.
Risk Factors for Oral Shingles
While the varicella-zoster virus can affect anyone who has had chickenpox, some individuals are at a higher risk of developing oral shingles. Several factors can contribute to the reactivation of the virus and increase the likelihood of developing oral shingles:
Age: People over 50 years old are more likely to develop shingles because their immune system weakens with age.
Weakened Immune System: Conditions such as HIV/AIDS, cancer, or treatments like chemotherapy can weaken the immune system and make it easier for the varicella-zoster virus to reactivate.
Stress: High levels of stress can weaken the immune system and trigger the reactivation of the virus.
Trauma or Injury: Physical trauma, especially to the face or mouth, can trigger the reactivation of the virus.
Certain Medications: Medications that suppress the immune system, such as steroids or immunosuppressive drugs, can increase the risk of developing shingles, including oral shingles.
Previous Chickenpox: Anyone who had chickenpox during childhood is at risk for developing shingles later in life.
Vaccination Status: People who have not been vaccinated against chickenpox or shingles are at a higher risk of developing oral shingles.
Symptoms of Oral Shingles
Oral shingles can cause a variety of symptoms. The most common ones include:
Pain or Burning Sensation: Before the rash appears, individuals may experience pain, tingling, or a burning sensation in the area of the mouth or face.
Blisters and Rash: A rash develops around the affected area. This rash is usually painful and can form into small blisters. The blisters may break open and leak fluid.
Swelling and Redness: The affected area may become swollen and red, making it uncomfortable to talk, eat, or drink.
Fever and Fatigue: Some people experience flu-like symptoms, including fever, tiredness, and general discomfort.
Difficulty Eating or Drinking: The pain and sores in the mouth can make it difficult to chew or swallow food.
Headache: A headache may accompany the outbreak of oral shingles.
Sensitivity to Light: People with shingles affecting the face, including the mouth area, may experience sensitivity to light, especially if the eyes are involved.
Changes in Taste: Some individuals report altered taste or a loss of taste in the affected area.
How Is Oral Shingles Diagnosed?
If you suspect you have oral shingles, it is essential to visit a healthcare provider for a proper diagnosis. A doctor will examine your symptoms, including the rash and pain, and may ask about your medical history, including whether you had chickenpox in the past.
In some cases, a laboratory test may be conducted to confirm the presence of the varicella-zoster virus. This test may involve a sample from the blisters or an analysis of your blood.
Treatment for Oral Shingles
While there is no cure for shingles, treatment can help manage symptoms, reduce the severity of the condition, and shorten the duration of the outbreak. The goal of treatment is to relieve pain, reduce inflammation, and prevent complications.
Antiviral Medications: Doctors may prescribe antiviral medications, such as acyclovir, valacyclovir, or famciclovir. These medications can help stop the virus from spreading and speed up recovery. They are most effective when started early, within 72 hours of the onset of symptoms.
Pain Relief: Over-the-counter pain medications, such as ibuprofen or acetaminophen, can help relieve mild to moderate pain. In more severe cases, stronger prescription painkillers may be necessary.
Topical Creams: Pain-relieving creams, such as those containing capsaicin or lidocaine, may help soothe the pain of oral shingles.
Corticosteroids: In some cases, corticosteroids may be prescribed to reduce inflammation and improve recovery.
Home Remedies: Keeping the mouth clean and avoiding irritants like spicy or acidic foods can help alleviate discomfort. Rinsing the mouth with warm saltwater may also help reduce pain.
Vaccination: The shingles vaccine, which is recommended for people over 50, can help prevent shingles or reduce the severity of the symptoms if the virus does reactivate.
Complications of Oral Shingles
Oral shingles can lead to complications, particularly if left untreated or if the immune system is weakened. Some potential complications include:
Postherpetic Neuralgia: This is a condition where the pain from shingles persists long after the rash has healed. It is more common in older adults and can be debilitating.
Eye Involvement: If the virus affects the eyes, it can lead to complications such as conjunctivitis, corneal ulcers, or even vision loss in severe cases.
Secondary Infections: The open blisters caused by oral shingles can become infected by bacteria, leading to additional complications.
Scarring: In rare cases, the rash and blisters may leave scars, especially if the person scratches or picks at them.
Prevention of Oral Shingles
While you cannot completely prevent oral shingles, certain steps can reduce your risk:
Vaccination: The shingles vaccine is effective in preventing the reactivation of the varicella-zoster virus. It is recommended for adults over 50 years old.
Manage Stress: Reducing stress through relaxation techniques, exercise, or therapy can help keep your immune system strong.
Healthy Lifestyle: Eating a balanced diet, getting regular exercise, and avoiding smoking or excessive alcohol consumption can support your immune system.
Avoid Close Contact with Infected Individuals: Although shingles itself is not contagious, the varicella-zoster virus can be spread to someone who has never had chickenpox.
Conclusion
Oral shingles is a painful condition that occurs when the varicella-zoster virus reactivates in the mouth area. While it is less common than shingles on other parts of the body, it can cause significant discomfort. The good news is that antiviral medications and pain management strategies can help control symptoms and speed up recovery.
If you suspect you have oral shingles, it is important to see a healthcare provider for an accurate diagnosis and appropriate treatment. With early intervention, most people recover fully from oral shingles without long-term complications.
