Tips on Coping with Mouth, Gum, and Throat Problems Related to Radiation Therapy
Understanding the Problem

Using Coping Strategies
- Check your mouth every day to detect problems, such as mouth sores or white patches. Report any problems to your doctor.
- Keep your mouth moist. You can do this by:
- Sucking on ice
- Sipping water or spraying your mouth with water often throughout the day
- Chewing sugar-free gum or sucking on hard candy
- Taking medication prescribed by your doctor to increase saliva
- Brush your teeth, gums, and tongue after eating and before going to bed. Use a soft toothbrush and fluoride toothpaste. Also, floss gently once a day.
- Do not use mouthwashes that contain alcohol. Instead, mix ¼ teaspoon (1.23 milliliters [ml]) baking soda, 1/8 teaspoon (.62 ml) salt, and 1 cup (237 ml) of warm water. Rinse your mouth with this solution every 1-2 hours.
- If you wear dentures, soak and brush them every day.
- Do not smoke cigarettes, cigars, pipes or use chewing tobacco.
