Yes. There are a several things you can do to help alleviate the discomfort of mouth sores (called mucositis), including:
Staying hydrated will help. Drink a lot of fluids.
Try sucking on ice chips to keep your mouth moist.
Many patients find that chewing sugarless gum or sucking on hard candy can help.
Try eating moist foods instead of dry, scratchy foods. Moistening dry foods before chewing them may be helpful.
Avoid very acidic foods, like tomatoes, oranges, and grapefruits, which that can exacerbate the sores. Try eating gentler foods like apricots, pears, beans, squash or peas.
Avoid very salty and spicy foods.
Rinse your mouth every 3 to 4 hours with a mixture of 1/2 teaspoon baking soda or salt and
8 ounces of water.
Rinse with alcohol-free mouthwash, like Biotene, every 2 hours. You might want to try a chamomile mouthwash, which has a soothing effect on the mouthís mucous membranes.
Keeping your lips moist with a nurturing balm can also help.
Use a soft toothbrush. If that is too painful, use cotton swabs to brush your teeth.
