Oral mucositis is a sore, inflamed mouth and throat that can occur during chemotherapy, radiotherapy, or other cancer treatments. This condition can make everyday activities such as eating, drinking, brushing teeth, and wearing dentures uncomfortable. Many people search for “mucositis relief,” “chemo sore mouth,” or “sore mouth from radiotherapy” when looking for practical ways to manage discomfort while supporting oral hygiene.
Explore easy-to-use pharmacy-grade options, including dry mouth sprays for instant moisture, mouth ulcer gels for targeted relief, protective pastes that shield sore areas, and soothing lozenges or pastilles for mouth-to-throat discomfort. Daily essentials like alcohol-free mouthwash and gentle toothpaste are also available to help maintain oral care. If you’re undergoing cancer treatment, always check labels and speak to your pharmacist or oncology team for guidance on suitable products.

FAQs
What is oral mucositis?
Oral mucositis is inflammation and soreness of the mouth or throat lining, often occurring during chemotherapy or radiotherapy, making eating, drinking, and oral care uncomfortable.
What products can help a sore mouth during treatment?
Supportive options include alcohol-free mouthwash, gentle toothpaste, dry mouth sprays, ulcer gels, protective pastes, and lozenges. Always check suitability with your pharmacist or oncology team.
What’s the difference between dry mouth and mouth ulcers?
Dry mouth (xerostomia) is reduced saliva causing a sticky or sore feeling. Mouth ulcers are painful localized spots. Some people have both simultaneously. Sprays help dryness; gels or pastes target sore areas.
Is mouthwash safe for sore mouths?
Alcohol-free or sensitive mouthwashes are usually well-tolerated. If a product causes burning or worsens symptoms, stop using it and seek a gentler alternative.
What should I avoid if my mouth is sore?
Very hot, spicy, acidic, or strong-flavoured foods may increase discomfort. Stick to what you can tolerate and consult a healthcare professional if eating or drinking is difficult.
Can mucositis indicate infection during chemotherapy?
Mucositis can increase infection risk, especially if your immune system is lowered. Seek urgent advice if you develop a fever, spreading swelling, pus, or worsening pain.
When should I seek urgent help?
Contact a healthcare professional immediately for fever, severe pain, difficulty swallowing, bleeding that won’t stop, dehydration signs, or suspected infection—especially during chemotherapy or radiotherapy.
