If you’re undergoing radiotherapy for head and neck cancer, you may have heard about oral mucositis—a painful side effect that can make eating, drinking, and speaking difficult. Recent research suggests that Limosilactobacillus reuteri, a beneficial probiotic strain, could help reduce its severity. At Melbourne Oral Medicine, we stay updated with the latest evidence-based treatments to support your oral health during cancer care. Here’s what you need to know about this emerging option.

What Is Oral Mucositis?

Oral mucositis is inflammation and ulceration of the mouth’s lining, often caused by high-dose radiotherapy or chemotherapy. It typically appears within 1–2 weeks of treatment and can last for several weeks, leading to symptoms like:

• Painful sores or white patches in the mouth
• Difficulty swallowing or chewing
• Increased risk of infections
• Altered taste or dry mouth

While oral mucositis is common in cancer patients, its severity can vary. If symptoms become severe—such as persistent bleeding, fever, or difficulty breathing—seek medical attention immediately.

How Can Limosilactobacillus reuteri Help?

A 2024 study published in Nature Communications explored the use of Limosilactobacillus reuteri (formerly known as Lactobacillus reuteri) as a preventive measure for radiation-induced oral mucositis. The research found that this probiotic strain may help reduce inflammation and promote healing by modulating the gut-mouth axis and supporting immune balance. While more clinical trials are needed, early results are promising for patients undergoing radiotherapy.

Why Is Early Triage Important?

If you’re experiencing persistent mouth sores or discomfort during or after radiotherapy, it’s crucial to rule out complications like infections or late-stage damage. A remote consultation with our Oral Medicine Specialist, Dr Suhaib Alqudah, can help assess your symptoms without the need for travel. During your telehealth appointment, we may:

• Review your medical history and current medications
• Discuss potential dietary or probiotic interventions (like L. reuteri)
• Recommend oral hygiene strategies to prevent secondary infections
• Arrange blood tests or imaging if needed for further evaluation

This approach ensures you receive personalised care while minimising unnecessary clinic visits.

When Should You Seek Help?

While mild oral mucositis may resolve on its own with supportive care, seek professional advice if you experience:

• Severe pain that interferes with eating or drinking
• Signs of infection (pus, fever, or worsening sores)
• Difficulty opening your mouth or swallowing
• Unusual bleeding or persistent white patches

Our Australia-wide telehealth consultations allow you to discuss these concerns with Dr Alqudah from the comfort of home, ensuring timely intervention.

Question? Can Limosilactobacillus reuteri replace other treatments for oral mucositis?

No, L. reuteri is not a standalone cure but may be used as a supportive measure alongside standard care, such as mouth rinses and pain management. Always follow your oncologist’s recommendations and consult our team for personalised advice.

Question? Is this probiotic safe for everyone?

While generally considered safe, L. reuteri may interact with certain medications or immune-suppressing treatments. Dr Alqudah will assess whether it’s suitable for your specific case during your consultation.

Question? How soon can I expect results if I try this?

Effects vary by individual, but some patients report reduced inflammation within weeks of starting L. reuteri. Consistency and proper oral hygiene are key to seeing benefits.
