The facts about Xerostomia
and how extra saliva can help.
How big a problem is Xerostomia? Over 10 million people in the UK suffer
from a sensation of dry mouth (xerostomia), the subjective report of oral
dryness.
The use of medication is one of the most common causes of xerostomia.
Over 400 commonly used drugs have been implicated in its aetiology.
These include antidepressants, antihistamines, antihypertensives,
antipsychotics, antiemetics, anticholinergics, decongestants, diuretics
and other blood pressure drugs.
Dry mouth is also associated with Rheumatoid Arthritis, Systemic Lupus
Erythematosis, Diabetes, Sjögren's Syndrome, Parkinson's Disease and
HIV/AIDS.
Oral dryness and quality of life. Xerostomics commonly suffer from caries
and oral soft tissue irritation, resulting in soreness and painful inflammation
within the oral cavity. Dry mouth sufferers are more susceptible to bacteria
and yeast infections (candidiasis). Diminished salivary flow results in
problems with tasting, chewing and swallowing food. Mouth malodor
(halitosis) is a common symptom. Speaking is also uncomfortable and
inhibited. Individuals who suffer with dry mouth experience both
psychological distress and social embarrassment.
Use of sugarfree gum to stimulate saliva. Saliva is a protectant against
plaque acid attack, tooth demineralisation, periodontal gingival disease
and oral infections.
Recently, considerable success has been achieved in the use of sugarfree
gum to relieve the symptoms of xerostomia by stimulating salivary flow.
Research among xerostomia patients has shown chewing gum stimulates
saliva by up to 7 times its normal flow rate relative to resting saliva,
providing immediate relief. Several studies have also shown that frequent
chewing of sugarfree gum has a residual effect on salivary flow even when
gum is no longer chewed.
Sugarfree gum for symptomatic relief. Xerostomia is likely to become more
widespread and take on increasing significance as our population becomes
older and more reliant on medications. Sugarfree gum provides simple and
effective relief from this common and often debilitating condition.
