A sore mouth and throat may be caused by radiation therapy, certain medications, chemotherapy and/or infections. Eating can be made easier by taking care of your mouth and carefully choosing the foods that you eat.

General Mouth Care

  • Make sure your doctor is aware of any mouth problems you may be experiencing. Your doctor or nurse will be able to give you tips about mouth care and mediations that will ease mouth or throat pain.
  • Rinse your mouth with baking soda and water mouthwash often during the day to help clean and refresh your mouth. See below for the recipe.
  • Drink at least 8 glasses of fluids daily to avoid dehydration.
  • Make every bite count. Choose foods and drinks that are high in calories and protein.
  • Eat and drink frequently during the day. Try eating every two hours and sipping fluids throughout the day.
  • Choose foods that are easy for you to chew and swallow. Start with high calorie fluids if chewing is difficult for you. Gradually introduce solid foods as you are able.
