Routine Oral Care

Continuing good dental hygiene during and after cancer treatment can reduce complications such as cavities, mouth sores, and infections. It is important to clean the mouth after eating. The following are guidelines for everyday oral care during chemotherapy and radiation therapy:

Tooth brushing

• Brush teeth and gums with a soft bristle brush 2 to 3 times a day for 2 to 3 minutes.

• Rinse the toothbrush in hot water every 15 to 30 seconds to soften the bristles, if needed.

• If it is necessary to use a foam toothbrush, use it with an antibacterial rinse, when possible.

• Allow the toothbrush to air dry between brushings.

• Choose toothpaste with care:
  • Use a mild-tasting toothpaste; flavoring may irritate the mouth.
  • If toothpaste irritates the mouth, brush with a solution of 1 teaspoon of salt added to 4 cups (1 quart) of water.
  • Use a fluoride toothpaste.

Rinsing

• Rinse the mouth 3 or 4 times while brushing.
• Avoid rinses containing alcohol.
• One of the following rinses made with salt and/or baking soda may be used:
  • 1 teaspoon of salt in 4 cups of water.
  • 1 teaspoon of baking soda in 1 cup (8 ounces) of water.
  • ½ teaspoon salt and 2 tablespoons baking soda in 4 cups of water.
• An antibacterial rinse may be used 2 to 4 times a day for gum disease. Rinse for 1 to 2 minutes.
• If dry mouth occurs, rinsing may not be enough to clean the teeth after a meal. Brushing and flossing may be needed.

Flossing

• Floss gently once a day.

Lip care

• Use lip care products to prevent drying and cracking.

Oral Mucositis

Mucositis is an inflammation of mucous membranes in the mouth.

The terms “oral mucositis” and “stomatitis” are often used in place of each other, but their meanings are different.

• Mucositis is an inflammation of mucous membranes in the mouth. It usually appears as red, burn-like sores or as ulcer -like sores throughout the mouth.

• Stomatitis is an inflammation of tissues in the mouth, such as the gums, tongue, roof and floor of the mouth, and tissues inside the lips and cheeks. It includes infections of mucous membranes.

Mucositis may be caused by either radiation therapy or chemotherapy. In patients receiving chemotherapy, mucositis will heal by itself, usually in 2 to 4 weeks when there is no infection. Mucositis caused by radiation therapy usually lasts 6 to 8 weeks, depending on the duration of treatment.

The following problems may occur:

• Pain.
• Infection.
• Bleeding, in patients receiving chemotherapy. Patients undergoing radiation therapy usually do not have a bleeding risk.
• Inability to breathe and eat normally.

Swishing ice chips in the mouth for 30 minutes may help prevent mucositis from developing in patients who are given fluorouracil. Medication may be given to help prevent mucositis or keep it from lasting as long in patients who undergo high-dose chemotherapy and bone marrow transplant.

Care of mucositis during chemotherapy and radiation therapy focuses on cleaning the mouth and relieving the symptoms.

Treatment of mucositis caused by either radiation therapy or chemotherapy is generally the same. After mucositis has developed, proper treatment depends on its severity and the patient’s white blood cell count. The following are guidelines for treating mucositis during chemotherapy, stem cell transplantation, and radiation therapy:

Cleaning the mouth

• Clean the teeth and mouth every 4 hours and at bedtime, more often if the mucositis becomes worse.

• Use a soft bristle toothbrush.

• Replace the toothbrush often.

• Use water-soluble lubricating jelly to moisturize the mouth.

• Use bland rinses or plain sterile water. Frequent rinsing removes particles and bacteria from the mouth, prevents crusting of sores, and moistens and soothes sore gums and the lining of the mouth. The following rinse may be used to neutralize acid and dissolve thick saliva:
  • ½ teaspoon salt and 2 tablespoons baking soda in 4 cups of water.

• If crusting of sores occurs, the following rinse may be used:
  • Equal parts hydrogen peroxide and water or saltwater (1 teaspoon of salt in 4 cups of water).

This should not be used for more than 2 days because it will keep mucositis from healing.

Fatigue from chemotherapy can range from a mild to extreme feeling of being tired. Many people describe fatigue as feeling weak, weary, worn out, heavy, or slow. Resting does not always help.

Many people say they feel fatigue during chemotherapy and even for weeks or months after treatment is over. Fatigue can be caused by the type of chemotherapy, the effort of making frequent visits to the doctor, or feelings such as stress, anxiety, and depression. If you receive radiation therapy along with chemotherapy, your fatigue may be more severe.

Fatigue can also be caused by

• Anemia
• Pain
• Medications
• Appetite changes
• Trouble sleeping
• Lack of activity
• Trouble breathing
• Infection
• Doing too much at one time
• Other medical problems

Fatigue can happen all at once or little by little. People feel fatigue in different ways. You may feel more or less fatigue than someone else who gets the same type of chemotherapy.

Ways to manage

• Relax. You might want to try meditation, prayer, yoga, guided imagery, visualization, or other ways to relax and decrease stress.
• Eat and drink well. Often, this means 5 to 6 small meals and snacks rather than 3 large meals. Keep foods around that are easy to fix, such as canned soups, frozen meals, yogurt, and cottage cheese. Drink plenty of fluids each day–about 8 cups of water or juice.

Plan time to rest. You may feel better when you rest or take a short nap during the day. Many people say that it helps to rest for just 10 to 15 minutes rather than nap for a long time. If you nap, try to sleep for less than 1 hour. Keeping naps short will help you sleep better at night.

• Be active. Research shows that exercise can ease fatigue and help you sleep better at night. Try going for a 15-minute walk, doing yoga, or riding an exercise bike. Plan to be active when you have the most energy. Talk with your doctor or nurse about ways you can be active while getting chemotherapy.
• Try not to do too much. With fatigue, you may not have enough energy to do all the things you want to do. Choose the activities you want to do and let someone else help with the others. Try quiet activities, such as reading, knitting, or learning a new language on tape.

Sleep at least 8 hours each night. This may be more sleep than you needed before chemotherapy. You are likely to sleep better at night when you are active during the day. You may also find it helpful to relax before going to bed. For instance, you might read a book, work on a jigsaw puzzle, listen to music, or do other quiet hobbies.

• Plan a work schedule that works for you. Fatigue may affect the amount of energy you have for your job. You may feel well enough to work your full schedule. Or you may need to work less–maybe just a few hours a day or a few days each week. If your job allows, you may want to talk with your boss about ways to work from home. Or you may want to go on medical leave (stop working for a while) while getting chemotherapy.
• Let others help. Ask family members and friends to help when you feel fatigue. Perhaps they can help with household chores or drive you to and from doctor’s visits. They might also help by shopping for food and cooking meals for you to eat now or freeze for later.
• Learn from others who have cancer. People who have cancer can help by sharing ways that they manage fatigue. One way to meet others is by joining a support group–either in person or online. Talk with your doctor or nurse to learn more.

• Try not to do too much. With fatigue, you may not have enough energy to do all the things you want to do. Choose the activities you want to do and let someone else help with the others. Try quiet activities, such as reading, knitting, or learning a new language on tape.

• Keep a diary of how you feel each day. This will help you plan how to best use your time. Share your diary with your nurse. Let your doctor or nurse know if you notice changes in your energy level, whether you have lots of energy or are very tired.
• Talk with your doctor or nurse. Your doctor may prescribe medication that can help decrease fatigue, give you a sense of well-being, and increase your appetite. He or she may also suggest treatment if your fatigue is from anemia.

Changes in taste are common during chemotherapy and radiation therapy.

Change in the sense of taste is a common side effect of both chemotherapy and head and/or neck radiation therapy. Foods may have no taste or may not taste as they did before therapy. These taste changes are caused by damage to the taste buds, dry mouth, infection, and/or dental problems. Chemotherapy patients may experience unpleasant taste related to the spread of the drug within the mouth. Radiation may cause a change in sweet, sour, bitter, and salty tastes.

In most patients receiving chemotherapy and in some patients undergoing radiation therapy, taste returns to normal a few months after therapy ends. For many radiation therapy patients, however, the change is permanent. In others, the taste buds may recover 6 to 8 weeks, or later, after radiation therapy ends. Zinc sulfate supplements may help with the recovery for some patients.
