Xerostomia (Dry Mouth)

Xerostomia OR Dry Mouth

What is Xerostomia?

Xerostomia is the condition when your salivary gland doesn’t produce enough saliva to keep the mouth wet.

Why Saliva is important for mouth health?

Saliva is very important to keep the mouth healthy. It moistens and breaks down food, washes away food particles from the teeth and gums, and helps people with swallowing. Lack of saliva makes chewing, swallowing, and even talking difficult.

Saliva keeps harmful germs in check. Therefore, the lack of saliva also increases the risk of tooth decay and fungal infections in the mouth. Saliva also contains important minerals such as calcium and phosphate that help keep teeth strong and fight tooth decay.

What are the causes of Xerostomia (Dry Mouth)?

It can happen when you are nervous or stressed. Dry mouth is not a normal part of aging.

  • Diseases like Sjögren’s syndrome, HIV/AIDS, and diabetes
  • Side effects of medicines like anti-hypertensives, anti-depressants, etc.
  • Radiation therapy during cancer treatment. Radiation destroys the salivary glands.
  • Drugs used to treat cancer can make saliva thicker, causing dry mouth
