What causes dry mouth?

A permanent feeling of dry mouth or decreased saliva flow can be caused by:

Biological ageing - this is a contributing factor, but probably does not cause it

Systemic diseases such as:

Rheumatoid conditions (example: Sjogren's Syndrome)

Dysfunctional immune system (example: AIDS)

Hormonal disorders (example: Diabetes)

Neurological disorders (example: Parkinson's disease)

Decreased chewing ability resulting in a liquid diet and soft food choice which tend to decrease the flow of saliva

Surgical removal of salivary glands

Dry mouth can also occur as a result of:

Radiation therapy - radiation can cause permanent damage to the salivary glands.

Drugs or medications - over 400 drugs cause dry mouth as a side effect, including:

Decongestants

Diuretics

Antihypertensives

Antidepressants

Antihistamines

So what if I have a dry mouth?

Having a decreased flow of saliva has some potentially serious consequences. Heavy plaque and food accumulations tend to occur with dry mouth (xerostomia). This can lead to tooth decay and gum disease.

Saliva is the body's self-cleansing mechanism. It helps remove food, debris, and plaque from the tooth surfaces which helps protect against oral diseases.

Saliva also protects against cavities. It cleanses the tooth surfaces and neutralises acids thereby protecting the teeth from decay. People who have dry mouth are very susceptible to cavities, especially on the roots of their teeth.

How to control dry mouth?

Sip water frequently

Keep fluids at bedside at night

Chew sugarless gum

Avoid tobacco, alcohol and foods high in sugar

Adjust the air humidity in your home

Use a saliva substitute - this is a commercial product which attempts to "wet" the mouth like saliva does.

Establish a good plaque control programme because heavy plaque accumulations occur with oral dryness

Use fluoride toothpaste, rinse, or gel
