What is Dry Mouth?

Dry mouth - or xerostomia - is a surprisingly common condition that occurs when your salivary glands do not produce enough saliva to keep your mouth comfortably moist. It can range from a mild irritation to a significant daily - and nightly - disruption to your quality of life.

Symptoms can be sporadic or constant and may be worse at certain times of day - particularly at night, when saliva production naturally slows and discomfort intensifies.

Symptoms:

  • A persistent sticky or parched feeling in the mouth
  • Waking at night with a dry mouth and the urge to drink water
  • Cracked, sore lips and dry skin at the corners of the mouth
  • A burning or tingling sensation on the tongue and oral tissues
  • A dry, sore or raw-feeling throat
  • Difficulty chewing, swallowing or speaking
  • Bad breath
  • A change in taste perception

Why is Dry Mouth Worse at Night?

Saliva production follows your body's natural rhythm, stimulated during the day by eating, talking and swallowing, but slowing significantly during sleep. For those who already struggle with reduced saliva, this nightly drop can tip discomfort into real disruption. Mouth breathing, snoring, CPAP use, certain medications, and conditions such as Sjögren's Syndrome or sleep apnoea can make things worse.

XyliMelts are uniquely suited to overnight use. Place a disc on each side of your mouth before bed and let the slow-release formula work through the night, keeping your mouth moist so you can sleep undisturbed.
