In simple words

Dry mouth, also called xerostomia, is a dry or sticky mouth caused by reduced saliva or a change in saliva.

Clinical Meaning

Saliva protects teeth and helps with speech, eating, swallowing, and taste. Persistent dryness can cause discomfort, tooth decay, thrush, and difficulty eating.

Common Causes

  • Dehydration, anxiety, or breathing through the mouth at night
  • Medicines, including some antidepressants, antihistamines, and water tablets
  • Cancer treatment, oral thrush, or a blocked nose
  • Conditions such as diabetes or Sjögren's syndrome

Clinical Red Flags

Seek urgent medical attention at an emergency department or primary care clinic if you present with any of the following symptoms:

  • Arrange a review if dryness makes talking or eating difficult, persists after several weeks, or comes with dry eyes, frequent urination, mouth pain, swelling, bleeding, or white patches.
  • Seek urgent help for inability to swallow fluids, severe dehydration, confusion, or severe allergic swelling of the mouth or throat.
  • Do not stop a prescribed medicine without advice, even if you think it is causing dryness.

Lifestyle & Diet Support

Sip water regularly, use sugar-free gum or sweets if suitable, protect lips, brush twice daily with fluoride toothpaste, and use alcohol-free mouthwash. A pharmacist can advise on gels, sprays, or lozenges that keep the mouth moist.

Frequently Asked Questions

Yes. Many medicines can contribute. Ask the prescriber or pharmacist for advice rather than stopping it yourself.
Saliva helps protect teeth. Persistent dryness increases the risk of tooth decay and oral infections, so dental care is important.
Seek advice if it persists, affects eating or speaking, or is associated with dry eyes, mouth pain, swelling, bleeding, white patches, or increased urination.
