Dry Mouth / Xerostomia

Dry Mouth

Dry mouth, also known as xerostomia is a result of reduced saliva. To keep the mouth moist and healthy the normal flow of saliva is about 1.5 litres per day. Dry mouth cannot only affect both the health of teeth and gums but also the enjoyment and digestion of food. Untreated, dry mouth can lead to serious oral complications and health problems.

Saliva serves many important roles such as controlling pH balance, and washing away food. Saliva is also necessary for tasting, chewing, swallowing, digesting, speaking and lubricating the mouth. Saliva is also necessary for re-mineralizing teeth to help prevent cavities

Symptoms of Dry Mouth Include

-Stringy, sticky or foamy saliva -Bad Breath

In many cases it is not possible to correct the dry mouth itself, and treatment focuses on relieving the symptoms and preventing tooth decay and gum disease.

-Sip water & avoid sugary beverages which contribute to tooth decay

-Use sugar-free gum or hard candies

-Use over-the-counter saliva substitutes (lubricants) such as Biotene
