Safe Oral Hygiene Routines During Treatment
Cancer treatments like chemotherapy and radiation can make your mouth more sensitive—but that doesn’t mean you should stop brushing or flossing. In fact, consistent, gentle oral hygiene is one of the best ways to prevent painful complications like infections, mouth sores, or tooth decay.
This guide will walk you through a safe, daily routine that’s easy to follow—even on tough treatment days. It is important to see your dentist before starting chemotherapy or radiation. Some dental procedures should be completed prior to starting therapy to eliminate current or potential areas from infection.
Brush Gently, Twice a Day
- Use a soft-bristled toothbrush (or an extra-soft baby toothbrush if your mouth is sore).
- Brush with fluoride toothpaste—ask your dentist if prescription-strength is right for you.
- Don’t scrub—use small, circular motions and be gentle around your gum line.
Floss Once a Day – Carefully
- Flossing helps prevent gum infections, but go slowly and carefully.
- If your gums are bleeding or very sore, ask your dentist if it’s safe to pause flossing temporarily.
- Waterpiks or Waterflossers are a great adjunct. Make sure it is on the lowest setting available.
Rise After Every Meal
- Use a non-alcoholic, gentle mouth rinse—or make your own:
- Mix 1/2 tsp salt + 1 Tbsp. baking soda + 1 Qt water
- Avoid store-bought rinses that contain alcohol or strong mint flavors—they can sting sensitive tissues. Biotene or Spry are good alternatives.
Keep Your Mouth Moist
- Sip water frequently throughout the day.
- Suck on ice chips or sugar-free lozenges.
- Try saliva substitutes or moisturizing gels (your doctor or dentist can recommend a brand).
- Biotene sprays help throughout the day
- Frozen grapes are great too
