Why Is Saliva Important?

Saliva is the best natural defence against decay.

Acid from bacteria can be neutralised by saliva.

A dry mouth can increase your risk of decay.

Causes of reduced saliva might include:

• Medications -- especially neurological medications.
• Excessive intake of caffeine -- found in coffee, tea, chocolate and cola drinks.
• Working in a dry environment and not rehydrating often enough.
• Some specific diseases or conditions such as Sjogren's syndrome.
