How to Prevent and Relieve

Dry Mouth at Night

When you experience dry mouth, achieving a refreshing night’s sleep will be hard. Dry mouth is the condition caused by not having sufficient saliva to keep the mouth moisturized and lubricated. This is a problem that results from salivary glands not producing adequate saliva. Dry mouth can cause immense discomfort especially at night and can also lead to several negative effects on your oral health. This is more so given that saliva is needed to deal with acid and bacteria build up in the mouth. Saliva fights tooth decay and prevents bad breath. The medical term for dry mouth is Xerostomia. This is more of a symptom than a disorder.
