Dry mouth at night (xerostomia) most often results from breathing through the mouth. Side effects of medications such as blood pressure drugs, antidepressants and antihistamines, not drinking enough water, systemic diseases such as diabetes and Sjögren’s syndrome, and aging are also among the main causes. In the long term, it can pave the way for tooth decay and gum disease.
- Reduced saliva flow can lead to decay, gum inflammation and bad breath.
- It is recommended to see a dentist first for this complaint.
- If necessary, you will be referred to an ENT specialist or internist.
- Drinking water before bed and keeping the room humid may help.

What causes dry mouth while sleeping at night? Do you wake up in the morning with extreme dryness in your mouth, a sticky feeling on your tongue or difficulty swallowing? Dry mouth, medically called xerostomia, can seriously reduce quality of life, especially at night. More than just causing a feeling of thirst, this condition can also pave the way for tooth decay and gum disease in the long term.
What Causes Dry Mouth at Night?
There can be many different causes of dry mouth while sleeping. Here are the most common:
-
Mouth Breathing: Breathing through the mouth due to nasal congestion, a deviated septum or sleep apnea causes saliva to dry out quickly.
-
Medication Side Effects: Blood pressure medications, antidepressants and antihistamines can slow down the salivary glands.
-
Dehydration: Not drinking enough water during the day comes back as dry mouth at night.
-
Systemic Diseases: Conditions such as diabetes, high blood pressure and Sjögren’s syndrome are among the main causes of dry mouth.
-
Aging: Saliva production can naturally tend to decrease with age.
How Does Dry Mouth Affect Dental Health?
Saliva neutralizes acids in the mouth and cleans the teeth naturally. Reduced saliva flow during the night can lead to the following problems:
-
Rapidly progressing tooth decay.
-
Gum inflammation and recession.
-
Severe bad breath (halitosis).
