One of the unexpected side effects of chemotherapy is mouth sores. Some types of chemo, as well as some radiation treatments, affect the sensitive tissue of your lips, cheeks, gums, and throat. This condition is called mucositis, and it's a common side effect of cancer treatments.
You may develop burn-like sores anywhere in your mouth or throat or on your lips. You may also have generalized swelling or tenderness all over your mouth and throat. The symptoms can make it uncomfortable to eat, drink, or talk.
Taking some precautions before and during treatment may help you minimize the effects of mouth sores.
See the Dentist
Before you start chemo, you should pay a visit to your dentist. If you have any cavities or gingivitis, your dentist can treat those for you. You want your teeth and gums to be as healthy as possible before treatment begins.
Take Care of Your Mouth
It's important to brush and floss during chemo. Your immune system will be suppressed, and you'll be more prone to infections of all kinds. Taking care of your teeth and gums will lower the chances that you'll have problems with your general dental health.
Preventing Mouth Sores
Your doctor may have ways to reduce your risk of mouth sores. Ask about what medications you'll be taking. If your breast cancer treatment plan includes a drug called fluorouracil {5-FU), swishing cold water or ice chips in your mouth might prevent sores.
Managing Pain From Mouth Sores
If you start having pain in your mouth, you should avoid foods and drinks that can make it worse, like:
- Alcohol
- Mouthwash that contains alcohol
- Salty or spicy foods
- Acidic foods and drinks like citrus fruits and juices, tomatoes, and tomato sauce
- Very hot or cold foods and liquids
- Tobacco
Your doctor can suggest topical medications to numb the pain in your mouth. There are numbing creams you can put on small areas of your lips or inside your mouth. If your whole mouth is hurting, there are rinses that can coat the entire area and provide some relief.
Rinsing your mouth regularly may help as well. You can use lukewarm water or a mouthwash that doesn't have alcohol. Your doctor may suggest a rinse of salt water or water and baking soda.
Before you begin treatment, you should talk to your doctor about the possibility of mouth sores. They can tell you what specific steps you need to take before your chemo regimen begins. If you develop sores, ask them for advice on relieving the pain.
