What is Dry Mouth?

Dry Mouth or Xerostomia is not a disease in itself, but can
be a symptom of certain diseases.

It can negatively affect a patient's quality of life-impacting
on eating habits, nutritional health, speech, taste, tolerance
to dental prosthesis (such as dentures) and can increase
the likelihood of dental decay.

What are the causes of Dry Mouth?

Dry Mouth can result from a number of causes, such as
the use of
certain drugs (such as anti-hypertensives,
tricyclic anti-depressants, analgesics, tranquilizers,
diuretics and anti-histamines); inflammatory conditions
such as
Mumps, TB, Sarcoidosis and Sjögren's
Syndrome; obstructions such as salivary stones;
conditions such as
dehydration, diabetes, cardiac and
renal failure, toxic goitre, menopause and senility;
nutritional causes such as
Vitamin A and iron deficiency;
cancer treatment such as chemotherapy and radiotherapy;

What can be done to relieve Dry Mouth?

The lack of saliva can have a profound effect on the mouth and the teeth.

There are a number of things you can do to relieve the symptoms:

  • Sip / drink water frequently.
  • Stimulate saliva with sugar-free gum (such as Xylitol), diabetic sweets, Salivix
    or SST if advised.
  • Keep your mouth clean, paying special attention to the teeth.
  • Use an artificial saliva (Artificial Saliva, Glandosane, Luborant) or saliva
    substitute (such as Orthana or Oral Balance-Biotène).
  • Use an antiseptic mouthwash (such as Corsodyl or Biotène).
  • Avoid alcohol-based mouth rinses.
  • Spray a water and glycerine solution into your mouth, mixed in a small aerosol
    bottle.
  • Always take water or non-alcoholic drinks with meals.
  • Avoid anything that worsens the dryness, such as certain drugs (see above),
    alcohol, smoking, caffeine and mouth-breathing.
  • Protect against dental decay by using a Fluoride mouth rinses / gels (such as
    Fluorigard), regular dental checks, avoiding sugary foods / drinks and sticky
    food.
  • Protect against Thrush & Halitosis by your mouth very clean and moist, rinsing
    twice daily with chlorhexidine (Corsodyl, Chlorhex or Eludril) or Triclosan
    (Plax), brushing or scraping of tongue, keeping dentures out at night and
    soaked in hypochlorite (eg Miltons or Dentural) and use of anti-fungals (if
    prescribed by your clinician).
  • Protect the lips with a lip salve or petroleum jelly (eg Vaseline).
  • Consider a humidifier in the room.

You can also make dietary changes to help the condition - blended and mixed foods
are easier to swallow.

Eat hard cheeses instead of soft cheeses and use
sucralose in place of sugar.  
Avoid spicy, hard crunchy or dry foods.  Take small bites and eat slowly.  
Pineapple has an enzyme that helps clean the mouth.

Drugs such as
pilocarpine or cevimeline are sometimes prescribed but these drugs
have many side effects that many people can not tolerate.
