Chemotherapy-Related Mouth Mucositis in Children
What is chemotherapy-related mouth mucositis?Chemotherapy is the use of medicines to treat cancer. The medicines can cause an inflammation of the lining of the mouth. The mouth is lined with mucous membranes. When these are inflamed, it’s called mouth mucositis. The mucous membranes may be red, swollen, painful, irritated, and have sores. The mucositis can affect any part of the digestive system, from the mouth to the anus. Mouth mucositis can be very painful. It can cause problems with eating, talking, and swallowing. It can also lead to serious infections and other problems.
What causes chemotherapy-related mouth mucositis?Chemotherapy kills cells that grow fast, such as cancer. Mucous membrane cells also grow fast, so some types of chemotherapy may harm them.
Who is at risk for chemotherapy-related mouth mucositis?
Children are more likely to get mouth mucositis than adults. Type, dose, and length of time of chemotherapy treatment are factors. A child may also be at higher risk of mouth mucositis due to:
- Poor dental and mouth care
- Loss of body fluid (dehydration)
- Being underweight
- Other long-term (chronic) health problems
- Cancer of the blood
- Smoking, using chewing tobacco, or drinking alcohol
What are the symptoms of chemotherapy-related mouth mucositis?
Mouth mucositis may start 5 to 10 days after starting chemotherapy. It may last for weeks. Symptoms can also occur a bit differently in each child. They may include:
- Red, shiny, swollen mouth, tongue, or gums
- Bleeding in the mouth

How is chemotherapy-related mouth mucositis diagnosed?
The healthcare provider will ask about your child's chemotherapy treatment and mouth symptoms. He or she will examine your child’s mouth, gums, and tongue. The healthcare provider may note how severe the problem is with a grading system. The mucositis may be graded from 1 to 4. This can help guide treatment. If needed, your child may be tested for other conditions. Some mouth conditions can have similar symptoms, such as oral candidiasis (thrush).
How is chemotherapy-related mouth mucositis treated?
There are many ways to treat mouth mucositis. Some treatments are simple and may help with mild symptoms. More severe symptoms may need to be treated with prescription medicines. In some cases, your child may need to spend some time in the hospital. Your child's oncologist will work with you to make your child as comfortable as possible.
To help ease mild symptoms, try the below:
- Give your child ice pops or ice water to cool and numb his or her mouth.
- If your child is old enough, give him or her ice chips, hard candy, throat drops (lozenges), or chewing gum.
- Don’t let your child eat spicy, hot, or rough foods.
- An older child can use mouth rinses after eating and at bedtime. Your child's oncologist or nurse can suggest rinses to try.
- Brush your child’s teeth very gently with a soft toothbrush.
- Use lip balm to keep your child’s lips moist. Don’t use petroleum jelly.
For more severe symptoms, your child's oncologist may advise:
- Cleaning sores with solutions that you mix or with other products
- Using pain relievers that are applied to the mouth or taken by mouth (oral)
- Time in the hospital if your child has an infection, or can’t eat or drink
What are possible complications of chemotherapy-related mouth mucositis?

- Infection in the mouth

Can chemotherapy-related mouth mucositis be prevented?
Mouth mucositis can’t be fully prevented. But there are medicines that can help prevent mucositis from happening. Talk with your child's oncologist about these medicines. You can also help lessen the chance and the severity of the condition by making sure your child:

- Has excellent mouth care every day, including brushing with a soft toothbrush and mild toothpaste, rinsing, and very gentle flossing
