Cutting Mouth Pain from Cancer Treatments

 image mouth pain

 We should treat our mouths with kid gloves through cancer treatments; as nearly half of us who go through chemo and or radiation deal with oral problems–especially people with head or neck cancer or who’ve had a bone marrow transplant. Here’s some of why the pain and trouble swallowing happen, and what you can do to keep your teeth and mouth healthy during and after treatments.


What’s the connection between cancer treatment and oral problems?


Chemotherapy goes after all rapidly dividing cells, the good and the bad ones. Cells in our mouths are among the most rapidly dividing ones. So you may have problems with your teeth and gums; moist lining of your mouth; and glands that make saliva. The consequences?  Pain (from inflammation). Dry mouth (from reduced saliva). Changes in taste known to some as “metal mouth” (from irritated taste buds). And then there are the lovely mouth sores.


How long can mouth pain last?

If you are doing chemo, know that mucositis (inflammation of mucous membranes in the mouth) typically heals on its own within 2 to 4 weeks. Mucositis from radiation may last 6 to 8 weeks.


Bonuses of seeing a dentist early after a cancer diagnosis 

You’ll increase your chance of being able to stay on track with your treatment regimen. You’ll likely bypass dehydration; malnutrition; gum infections; and later, tooth decay. With foods, well some of us still deal with metal mouth, but at least what you eat will taste closer to what it’s supposed to. And there’s a chance you’ll  nip this annoyance in the bud altogether. Also if you have dentures, you should make sure they fit well as soon as possible for smoother sailing through treatments.


Mouth Care Tips from the National Cancer Institute  

Routine care

  • Clean the mouth after eating
  • Brush with a soft bristle brush 2 to 3 times daily for 2 to 3 minutes. Brush where the teeth meet the gums and rinse often
  • Use a foam brush only if a bristle brush cannot be used, and use an antibacterial rinse
  • Rinse the toothbrush in hot water often to soften the bristles, if needed
  • Use a mild-tasting, fluoride toothpaste; flavoring may be irritating



  • One of the following rinses may be used:
      •    1 teaspoon of salt in 4 cups of water
      •  1 teaspoon of baking soda in 1 cup 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 daily for gum disease. Rinse for 1 to 2 minutes
      • If dry mouth occurs, brushing more often and flossing (once daily) may be needed


Lip care

  • Use lip care products to prevent drying and cracking


About eating and drinking

  • Drink a lot of water and suck on ice chips (especially helpful while you’re getting chemo)
  • Lay low on gum and hard candies, especially with sugar
  • Take a break from spicy or acidic foods like citrus fruits and juices
  • Eat soft foods, and if you still have trouble swallowing, soften your food with yogurt, gravy, broth, or other liquids
  • Sip liquids with your meals so food slides down easier


About mouthwashes

Mouthwash helps with pain and inflammation. But skip the ones containing alcohol. And if store-bought mouthwashes don’t work, you may want to ask your doctor about bringing out the big guns. There are prescriptions, like magic mouthwash (First-Mouthwash BLM, First-BXN Mouthwash, others). Magic mouthwash usually contains at least three of these ingredients:  An antibiotic, antihistamine or local anesthetic for pain, corticosteroid for inflammation.

There’s’ a fairly new prescription drug called Caphosol (generic name: artificial saliva solution). You may want to read up on it and ask your doctor about.
