Palliative cancer care - oral problems - Management
How should I manage someone with halitosis due to an oral problem?

  • Encourage:
    • Regular oral hygiene, including tongue cleaning.
    • Good care of dentures.
    • Fluid intake.
    • Modification of diet (e.g. exclude garlic and onions).
    • Smoking cessation.
  • Regular use of a gargle or mouthwash containing an antimicrobial agent (e.g. chlorhexidine) may reduce breath odour.
  • Consider artificial saliva if the mouth is very dry.
  • Treat any underlying cause. See:
Clarification / Additional information
  • Oral hygiene should include tooth brushing, tongue scraping, and dental flossing.
  • The tongue is the main source of malodour and can be cleaned with an ordinary toothbrush, a paediatric toothbrush, a tongue brush or a 'tongue scraper' [Davies and Finlay, 2005].
    • The aim of the cleaning is to remove the coating on the tongue without damaging the mucosa of the tongue.
    • Clean as far back as possible as the putrefaction occurs mainly on the posterior part of the tongue.
    • Discontinue cleaning once the coating has been removed or becomes difficult to remove.
  • A gargle or mouthwash should be used daily on waking and after meals and at bedtime.
  • Using cider and soda water in equal parts has also been suggested as a gargle/mouthwash [Regnard et al, 1997].
