It’s National Smile Month. In this blog, Quality and Evaluation Officer Rachael discusses some ways to keep your mouth healthy if you are going through cancer treatment.

National Smile Month is an annual campaign to promote good oral health (the health of our mouths). You can find out more about the campaign here.

The importance of oral health

Oral health is important to allow us to do many things we take for granted each day, such as talking, smiling and eating. The health of our mouths can also have a big impact on our identity and self-confidence.

Oral health and cancer

If you have cancer, you may be facing new challenges in looking after your oral health. This is because some treatments for cancer can lead to a sore or dry mouth. Treatments that can do this are:

Mouth problems usually gradually improve when treatment ends. But for some people changes may be permanent. Making changes to how you look after your mouth during and for a time after treatment can help with some problems.

Eating and drinking

If you have a sore or dry mouth, changing the way you eat and drink can improve your oral health, as well as making you feel more comfortable. It may help to:

  • drink plenty of fluids, especially water
  • keep your food moist by adding sauces and gravies
  • choose cold foods and drinks, as these may be soothing
  • avoid salty and spicy foods.


Other tips for a healthy mouth

Your doctor or specialist nurse will be able tell you about other things that can help. This might mean:

  • visiting your dentist before you start treatment
  • using a softer toothbrush
  • sucking on an ice cube to sooth your mouth
  • using a mouthwash recommended by your nurse or doctor.
