Managing Mouth Sores During Ovarian Cancer Treatment

Mouth sores (also called oral mucositis) are a common side effect of cancer treatment, and there are several practical strategies to help manage them effectively.

Why Mouth Sores Develop

Chemotherapy and radiation therapy attack rapidly dividing cells throughout your body—including the healthy cells lining your mouth. This damage can lead to painful sores, dry mouth, and changes in taste. The good news is that these sores are usually temporary and manageable with the right approach.

Practical Management Strategies

Dietary Approaches

Choose soft, moist, bland foods over spicy or acidic options that can irritate sores
Use a straw when drinking beverages to bypass sore areas in your mouth
Increase protein intake—the amino acids in protein may help mouth sores recover more quickly
Avoid foods that are hot, crunchy, or difficult to swallow
Consider nutritional drinks (like Ensure or Boost) if solid food is too painful

Oral Care Routine

Brush gently with a soft-bristled toothbrush after each meal
Rinse thoroughly with water or a salt-based mouth rinse (you can make one with a pint of cooled boiled water and a teaspoon of salt)
Avoid alcohol-based mouthwashes—they can make dry mouth worse
Flossing with traditional floss or a Waterpik is generally not recommended during treatment, as it can irritate your gums or mouth and potentially cause infection

Managing Dry Mouth

Your doctor can prescribe special mouthwash that helps generate saliva
Suck on sour candy or ginger candy—this stimulates saliva production
Use products designed to promote overnight salivation and prevent bacterial buildup (ask your nurse or pharmacist for recommendations)
Stay well-hydrated by drinking plenty of water throughout the day

When to Contact Your Care Team

Tell your oncologist or care team if:

Mouth sores are severe or spreading
You're having difficulty eating or drinking
You develop signs of infection (increased pain, swelling, or white patches)
Sores don't improve within a week or two after treatment

Your doctor may be able to prescribe topical numbing agents or other medications to help manage severe sores. In some cases, they might adjust your treatment timing or dosage if oral side effects are significantly affecting your quality of life.

Important Preventive Step

Have a thorough dental exam and cleaning BEFORE starting treatment. This is one of the most important things you can do. Addressing any existing dental issues beforehand helps prevent complications during treatment, including "chemo cavities" (tooth decay caused by changes in mouth bacteria during treatment).
