Mouth care

  • Good mouth care can enhance the quality of life for children in the palliative care setting
  • Full examination should always include inspection of the mouth as oral problems are easily overlooked, but can usually be easily managed

Consider cause and treat as appropriate:

  • Oral candidiasis
  • Dry mouth: mouth breathing, oxygen
  • Ulcers: traumatic, apthous, infectious
  • Bleeding gums
  • Dental caries
  • Gum hyperplasia
  • Medication e.g. morphine, antihistamines, anticholinergics; radiotherapy
Management

General measures

  • Keep mouth clean and moist. Clear a coated tongue by gently brushing with a soft toothbrush, or by using effervescent vitamin C
  • Regularly clean mouth and teeth with gauze dipped in water or mouthwash, particularly after eating/drinking
  • Refer to dentist if appropriate
  • Often a dry mouth can be a source of discomfort towards the end of life. This is well documented in the (more vocal) adult population and likely to a problem in children too. It often occurs in those who cannot eat or drink. General comfort can be increased by measures such as sucking ice or chips of ice lolly or sipping very cold water. Pleasure can still be had from placing tiny bits of chocolate in the mouth for example, but take care that you can retrieve less soluble substances if swallowing is an issue.

Dry mouth
  • If using oxygen, consider humidifying
  • Some medication will cause a dry mouth as a side effect e.g. morphine, anti-spasmodics, tricyclic anti-depressants and anticholinergic medication: consider changing or reducing dose if possible
  • Artificial saliva
    There are several preparations available in various forms including Glandosane spray
  • KY jelly
    Is well tolerated and can be used around the inside of the mouth

    Sucking fresh pineapple may help with dryness and also help to prevent candidiasis

    Applying Vaseline or a similar product regularly to lips will help prevent cracking
