Essential Oral Health Tips for Cancer Patients

Cancer treatment is a challenging journey, and while you focus on recovery, don't overlook your oral health. Chemotherapy, radiation to the head and neck, and certain medications can cause difficult side effects like mouth sores (mucositis), dry mouth, and an increased risk of infection and decay. Being proactive is key to managing these issues.

During Treatment: Gentle and Diligent Care

Before treatment, see your dentist to address any existing issues, as a healthy mouth reduces complications. Throughout your therapy, maintain a super-gentle, meticulous routine.

Use a soft-bristled toothbrush (or foam swab if needed) and a mild-tasting, fluoridated toothpaste; many find unflavoured or children's toothpaste helpful. Brush gently after every meal and before bed, and be sure to clean your tongue. If flossing causes bleeding, check with your care team.

Hydration is crucial for combating dry mouth (xerostomia). Sip water frequently, suck on ice chips or sugar-free sweets/gum. Avoid alcohol-based mouthwashes, which can be irritating. Instead, rinse several times a day with a bland solution like warm salt water or a prescribed rinse. Avoid sharp, hot, spicy, or acidic foods and use lip balm to soothe dry lips. Report any painful sores, bleeding, or white patches to your doctor immediately.

Life After Treatment: Long-Term Vigilance

Even after treatment, your mouth may be more vulnerable. Reduced saliva, especially after head and neck radiation, can lead to aggressive tooth decay.

Commit to lifelong, regular dental check-ups—every three to six months initially—and continue using a high-fluoride toothpaste or gel as prescribed by your dentist. Protect your teeth by limiting sugary and acidic foods and drinks, keeping them to mealtimes only. Maintaining this diligent approach will help you preserve your oral health and ensure your beautiful smile is part of your successful recovery.
