Reducing dental and gum problems

Dental and gum problems are a frequent side effect of cancer. Your doctor and dentist should work closely together to fix any problems with your teeth before you start treatment.

If you eat often or eat a lot of sweets, you may need to brush your teeth more often. Brushing after each meal or snack is a good idea.

Here are some other ideas for preventing dental problems:

  • let your doctor or dentist know about any dental problems you are having;
  • see your dentist regularly. Patients who are receiving treatment that affects the mouth — for example, radiation to the head and neck — may need to see the dentist more often than usual;
  • use a soft toothbrush. Ask your doctor, nurse, or dentist to suggest a special kind of toothbrush and/or toothpaste if your gums are very sensitive;
  • rinse your mouth with warm water when your gums and mouth are sore;
  • if you are eating foods high in sugar or foods that stick to your teeth brush or rinse your mouth afterward. In this way the sugar won't damage your teeth.

Sorbitol, a sugar substitute that is contained in many sugar-free foods, can cause diarrhoea. If diarrhoea is a problem for you, check the labels of sugar-free foods before you buy them and limit your use of them.
