What is Dry Mouth?

Dry mouth, also known as ‘xerostomia,’ is a condition in which the mouth stops producing enough saliva and helps to keep it adequately moist. This leads to the mouth being uncomfortably dry along with hoarseness in the throat.

The American Academy of Oral Medicine estimates that around 65% of the overall world population suffers from xerostomia(1).

Very commonly, dry mouth is caused due to the side effects of certain medicines, treatments, and infections. Also, it can also be caused by nerve damage, severe dehydration, or surgical removal of the salivary glands. The symptoms of dry mouth are:

  • Recurrent thirst
  • Dry tongue
  • Sore throat
  • Sores in the mouth
  • Bad breath
  • Problems in speaking, chewing and swallowing
