Coping with Mouth Problems
Cancer treatments, such as chemotherapy and radiation therapy to the head or neck, may cause changes in the mouth. Some of these changes are redness, dryness, swelling, ulcers and white patches, and are called “mucositis.” Mucositis most commonly occurs 7-14 days after the start of therapy and heals when your blood counts return to normal. Good mouth care is a must during cancer treatment.
- Check your mouth for changes every day.
- Brush with a soft toothbrush and toothpaste after meals, at bedtime or after vomiting. (If not eating, brush 4 times a day.) Rinse with tap water.
- Floss once a day if you usually floss. Do not floss areas that are sore or bleeding. Leukemia patients should check with their oncologist before flossing.
- Keep lips moist with lip balm.
- Drink plenty of fluids.
- Rinse your mouth often with water. Frequent rinsing 4-10 times a day can help reduce mouth problems.
- Do not use mouthwash that contains alcohol. You may be told to use special mouthwashes if you have teeth or gum disease.
- Only wear dentures when eating. Clean dentures daily and change solution daily.
- Avoid foods that are hot, spicy, salty or acidic. Soft, bland, cool foods are best. Avoid tobacco or alcohol.
Report to your doctor or nurse any of the following
- new ulcers or white patches
- difficulty swallowing
