Managing Mouth Sores From Cancer and Dry Mouth Throughout Treatment

When undergoing chemotherapy treatment and other cancer treatments, such as radiation treatment, dealing with side effects can feel overwhelming. Oral health issues like dry mouth, mouth pain, mouth sores, cavities, and a burning sensation in your mouth are common challenges for patients going through chemotherapy or radiation. While these symptoms can’t be fully resolved until your treatment is complete, there are steps you can take to manage them and make things more comfortable.

This article will walk you through practical tips for managing these oral health challenges.

Understanding Mouth Sores and Dry Mouth

1. What are Mouth Sores?

Mouth sores, also known as oral mucositis, are a common side effect of certain cancer treatments, particularly chemotherapy and radiation therapy. These sores can manifest as red or white patches, ulcers, or blisters on the tongue, gums, lips, or the lining of the mouth. They can even extend down the throat and into the digestive tract. The presence of mouth sores can cause significant pain and discomfort, making it difficult to eat, swallow, and speak. This can be particularly challenging for patients already dealing with the stress and fatigue of cancer treatments. Understanding what mouth sores are and recognizing their symptoms can help you take proactive steps to manage them effectively.

2. What is Dry Mouth?

Dry mouth, medically known as xerostomia, occurs when the salivary glands do not produce enough saliva, leading to a dry, sticky feeling in the mouth. This condition is often a side effect of cancer treatments like chemotherapy and radiation therapy, as well as certain medications. Dry mouth can make everyday activities such as eating, swallowing, and speaking more difficult. Additionally, it increases the risk of tooth decay and other oral health problems because saliva plays a crucial role in neutralizing acids and washing away food particles. Recognizing the symptoms of dry mouth early can help you take steps to alleviate the discomfort and protect your oral health.

Causes of Mouth Sores and Dry Mouth

1. Cancer Treatments That Can Cause Mouth Sores

Cancer treatments, including chemotherapy and radiation therapy, are known to cause mouth sores and dry mouth. Chemotherapy can damage the rapidly dividing cells that line the mouth and throat, leading to painful sores and ulcers. Radiation therapy, especially when targeted at the head and neck, can damage the salivary glands, reducing saliva production and causing dry mouth. Other cancer treatments, such as targeted therapy and immunotherapy, can also contribute to these oral health issues. Understanding the link between your cancer treatment and these side effects can help you and your healthcare team develop strategies to manage them effectively.

Managing Mouth Sores

1. Magic Mouthwash

Magic Mouthwash is often recommended by dentists and healthcare providers to help alleviate the discomfort of mouth sores. It’s not a one-size-fits-all solution since there are different formulations, but it’s worth exploring. If one version doesn’t work, ask your pharmacist or dentist about trying a different formula.

Magic Mouthwash isn’t available over the counter, so you’ll need a prescription. Until you can get one, a warm saltwater rinse can provide temporary relief. But don’t wait too long—schedule a visit with your dentist to find the best solution for your unique needs. Always consult your health care team to find the best solution for your unique needs.

2. L-Glutamine as an Option

Another option to consider is L-glutamine powder. Some studies suggest that using it as a mouthwash can help prevent mouth sores and reduce discomfort by soothing irritated tissue. While more clinical research is needed to confirm its effectiveness, it’s a safe topic to bring up with your healthcare team. Even if it doesn’t fully eliminate the pain, it might provide some additional relief.

3. Trial and Error with Products

Managing mouth sores often involves a bit of trial and error. There are many products available to help alleviate symptoms, but Magic Mouthwash is one of the most widely known and effective options. Be patient and open to experimenting with different remedies to find what works best for you.

Managing Dry Mouth (Xerostomia)

1. Over-the-Counter Products

Dry mouth, or xerostomia, is another common side effect of cancer treatment. Thankfully, there are numerous over-the-counter products designed to help, such as mouthwashes, sprays, mints, and toothpaste. If you’re not finding relief right away, don’t get discouraged! Keep experimenting until you find the right combination that works for you. Sucking on ice chips can also provide temporary relief by keeping your mouth moist.

2. Impact of Medications

Medications prescribed during cancer treatment—and even those for unrelated conditions like allergies or anxiety—can also contribute to dry mouth. These include antihistamines, antidepressants, narcotics, and certain blood pressure medications. That’s why it’s critical to keep your dentist informed about any medications you’re taking. They can adjust your oral care routine to better meet your needs and alleviate discomfort in your mouth or throat.

3. Bonus Tips for Dry Mouth

Stay Hydrated: Drinking plenty of water throughout the day can help keep your mouth feeling more comfortable.

Use a Humidifier: Adding moisture to the air, especially at night, can prevent your mouth from drying out while you sleep.

Preventing Infection and Maintaining Oral Hygiene

1. Importance of Home Care Routine

Maintaining a good oral hygiene routine is crucial, even when dealing with a mouth sore. When brushing and flossing is uncomfortable or painful, try using an over-the-counter numbing gel or spray before you brush and floss. This can help you clean your teeth properly without causing additional pain.

2. Risk of Cavities

Dry mouth and sore mouth increase your risk for cavities, so staying on top of your oral hygiene is even more important. Regular dental checkups and a consistent brushing and flossing routine can help minimize this risk.

3. Keeping Updated Health History

Always inform your dentist and dental hygienist about any medications you’re taking or health changes you’re experiencing. Keeping your health history up to date allows them to tailor their advice and care to your specific situation.

Mouth Sores From Cancer Treatments

Managing mouth sores and dry mouth during cancer treatment isn’t easy, but small steps can make a big difference in your comfort. Remember, this is all about finding relief and maintaining your oral health until your treatment is complete. Once you finish chemotherapy or radiation, your mouth will often start to heal and improve quickly. This is especially important for patients undergoing intensive treatments like a stem cell transplant.

Stay strong, stay hydrated, and don’t hesitate to reach out to your dentist or healthcare team for personalized advice. You’ve got this!
