Shingles and Oral Health: Understanding the Connection and Care

Back in 2018 I wrote a post on Shingles. This is basically an update. Why?: as the occurrence of shingles has increased (even my husband has suffered from it recently), I feel it is important to diagnose the condition early (get antivirals) and correctly (to avoid dental interventions if cause of pain is not identified).

Shingles, a painful viral infection caused by the varicella-zoster virus, is known for its characteristic rash and its association with chickenpox. While many people are aware of the skin-related symptoms, the connection between shingles and oral health is often overlooked. In this post, I will discuss the link between shingles and oral health, its impact on dental care, and how you can manage the condition for a healthier, happier life.

The Basics of Shingles:

Before delving into the oral health aspect, it’s important to understand the basics of shingles. Shingles, also known as herpes zoster, typically appears as a painful, blistering rash on one side of the body, often in a stripe or band-like pattern. It occurs due to the reactivation of the varicella-zoster virus, the same virus responsible for chickenpox. This reactivation often happens in individuals who have previously had chickenpox.

Shingles and the Oral Cavity:

Shingles can indeed affect the oral cavity, leading to a host of dental issues. The virus can attack the nerves in the head and neck region, potentially causing oral pain, tingling, or even a burning sensation. This pain can radiate from the face to the mouth, gums, and even the teeth, which is often misinterpreted as a dental issue. These symptoms are part of a condition known as “trigeminal zoster,” as the trigeminal nerve, responsible for sensations in the face, is often involved.

Oral Complications Associated with Shingles:

  1. Oral Pain: The most common oral symptom associated with shingles is intense pain, which can affect the mouth and face. This discomfort may make it difficult to chew, swallow, or speak.
  2. Cold Sores and Oral Ulcers: Shingles can sometimes manifest as cold sores or oral ulcers in and around the mouth. These sores can be painful and may lead to difficulty in eating or drinking.
  3. Dry Mouth: The medications prescribed to manage shingles can lead to dry mouth as a side effect. Dry mouth not only contributes to discomfort but also increases the risk of dental issues, such as tooth decay and gum disease.
  4. Loss of Taste: Some individuals with shingles may experience a temporary loss of taste sensation. This can affect one’s appetite and dietary choices.
  5. Neuralgia: Post-herpetic neuralgia is a common complication of shingles, which involves persistent pain in the affected area, including the oral cavity. This can disrupt one’s daily life and even impact oral hygiene practices.
  6. Secondary Infections: The weakened immune system and open sores caused by shingles can make the oral cavity vulnerable to secondary bacterial or fungal infections, such as thrush.

Oral Health Care During Shingles:

Taking care of your oral health during a shingles outbreak is crucial. Here are some steps to consider:

  1. Oral Hygiene: Continue brushing your teeth gently, but be extra cautious around any painful or ulcerated areas. A soft-bristle toothbrush may be more comfortable during this time.
  2. Oral Rinses: Rinsing your mouth with warm salt water can help soothe any mouth sores and maintain oral hygiene. Avoid commercial mouthwashes containing alcohol, as they can be irritating.
  3. Moisturise: If dry mouth is a concern, stay hydrated by drinking plenty of water. Consider using sugar-free gum or lozenges to stimulate saliva production.
  4. Diet: Stick to a soft, bland diet that minimizes irritation to your mouth and gums. Avoid spicy, acidic, or crunchy foods that may exacerbate discomfort.
  5. Pain Management: Consult with your healthcare provider or dentist about appropriate pain management techniques and medications.
  6. Avoid Irritation: Be mindful of any oral habits that could irritate your mouth, such as smoking, using tobacco products or vaping.
  7. Regular Dental Checkups: Even during a shingles outbreak, it’s important to maintain your regular dental appointments. Your dentist can monitor your oral health and provide guidance on managing any shingles-related issues.

Post-Shingles Oral Health:

After recovering from shingles, it’s important to continue monitoring your oral health. Post-herpetic neuralgia, a common complication of shingles, can persist, leading to chronic oral discomfort. Regular dental checkups are essential for addressing any ongoing issues and maintaining optimal oral health.

Shingles can have a significant impact on oral health, causing discomfort, pain, and other related issues in the mouth and oral cavity. By understanding the potential complications and taking proactive steps to manage them, individuals with shingles can maintain their oral health and overall well-being. Remember to consult with healthcare professionals for guidance and support throughout your shingles journey, ensuring a healthier and happier life beyond the pain and discomfort.
