Maintaining Dental Health During Chemotherapy: Tips for Cancer Patients

Going through chemotherapy is challenging in so many ways. While most people focus on managing fatigue, nausea, and hair loss, oral health is often overlooked. Yet, chemotherapy can take a toll on your mouth, causing dryness, soreness, infections, and changes in taste.  Taking care of your teeth and gums isn’t just about comfort; it can help you stay healthier and feel a little more in control during treatment.

The importance of oral care during chemo

Chemotherapy focuses on cells that multiply quickly, and these cells include cancer cells. It unfortunately spreads to healthy cells in your mouth, which can cause complications like:

• Dry mouth (xerostomia): A lack of saliva may result in discomfort during eating and speaking. 
• Mouth sores (mucositis): Painful ulcers can make even soft foods hard to swallow
• Infections: A weakened immune system makes your mouth more vulnerable
• Changes in taste: Your favourite foods might suddenly taste different or bland.

These side effects can make daily life harder and even affect your nutrition, which is why taking proactive steps matters.

Practical tips to keep your mouth healthy

• Brush gently, often: Use a soft-bristled toothbrush and brush after meals and before bed. Avoid scrubbing too hard, especially if your gums are sensitive.
• Floss carefully: Flossing is important, but do it gently. If your platelet counts are low, check with your healthcare team first.
• Stay hydrated: Drink plenty of water throughout the day. Chewing sugar-free gum or sucking on ice chips can help stimulate saliva.
• Rinse with saltwater or baking soda: A simple rinse—like 1/4 teaspoon of salt in a cup of warm water—can soothe sores and reduce bacteria. Avoid alcohol-based mouthwashes, which can sting.
• Mind your diet: Soft, bland foods are easier on the mouth. Cold foods like smoothies or ice cream can also provide relief for soreness.
• Avoid irritants: Steer clear of alcohol, tobacco, and overly spicy or acidic foods.
• Regular dental check-ups: See your dentist before starting chemotherapy and keep them informed throughout treatment. They can monitor problems early and provide tailored advice.

Your smile, your strength

Taking care of your teeth and gums during chemotherapy isn’t optional rather, it’s part of your overall health plan. Even easy measures such as mild brushing, hydration, or frequent visits to the dentist could make a big difference in comfort and safety. A study in The Lancet Regional Health, Southeast Asia, highlights that maintaining oral hygiene can reduce complications during treatment and even lower long-term health risks like cancer or cardiovascular disease.

During treatment, your mouth can become sore, but given a bit of attention, you can reduce complications and keep yourself as healthy and comfortable as possible.
