In daily life, many people are curious about questions like “What causes saliva drooling during sleep? What leads to dry mouth during sleep?” These seemingly ordinary phenomena often have multiple underlying factors. Understanding these reasons can not only clear up people’s doubts but also help detect potential health issues in a timely manner.
Causes of Saliva Drooling During Sleep
Saliva drooling during sleep can be attributed to several factors. Firstly, improper sleeping positions are a common cause. When sleeping on the stomach or side, the force of gravity makes it difficult for saliva in the mouth to stay in its normal position, thus easily causing it to flow out.
Especially for those who are accustomed to sleeping on their stomachs, the pressure on the face changes the oral cavity space, making saliva more likely to leak out.
Poor oral hygiene should not be overlooked. If oral cleaning is neglected, food residues accumulate between the teeth and along the gums, providing a breeding ground for bacteria and leading to oral inflammations such as periodontitis and gingivitis. Irritation from these inflammations increases saliva production.
Since swallowing actions decrease during sleep, the excess saliva flows out. Additionally, dental deformities, especially severe protrusion of the front teeth, can affect oral closure. As a result, the mouth cannot be fully closed during sleep, leading to saliva drooling.
Certain neurological diseases can also cause saliva drooling during sleep. For example, in patients with facial nerve palsy, the abnormal movement of facial muscles makes it impossible to properly control the muscles around the mouth, preventing normal saliva swallowing.
People with Parkinson’s disease, whose nervous system function is impaired, may experience muscle stiffness and swallowing dysfunction, often accompanied by saliva drooling during sleep.
Causes of Dry Mouth During Sleep
The causes of dry mouth during sleep are also quite complex. The most common one is insufficient water intake. If a person drinks little water during the day, the body becomes dehydrated, and as water continues to be lost during sleep at night, dry mouth occurs easily.
Moreover, sleep environment factors play a significant role. Extremely dry indoor air with low humidity causes the rapid evaporation of moisture in the mouth, leading to dryness.
When breathing through the mouth during sleep, air enters the mouth without being humidified by the nasal cavity, accelerating the loss of oral moisture.
Some diseases can also trigger dry mouth during sleep. In diabetic patients, elevated blood sugar increases osmotic pressure, resulting in frequent urination and significant water loss from the body, which causes dry mouth symptoms, even during sleep.
For patients with Sjögren’s syndrome, the autoimmune system attacks exocrine glands such as salivary glands, reducing saliva secretion, and dry mouth is one of its typical symptoms.
People with hyperthyroidism have an accelerated metabolism, consuming more water, and they are more prone to feeling dry mouth, especially during sleep.
Frequently Asked Questions
Do I need to see a doctor for saliva drooling and dry mouth during sleep? Occasional saliva drooling or dry mouth during sleep without other discomforts may be related to short – term factors.
You can first make self – adjustments, such as improving your sleeping position or increasing indoor humidity. However, if these symptoms occur frequently or are accompanied by other symptoms like pain, numbness, or sudden weight changes, it is advisable to seek medical advice promptly to rule out potential diseases.

Maintain good oral hygiene by brushing your teeth correctly twice a day and using dental floss to clean between your teeth. For saliva drooling caused by dental deformities, consult a dentist and consider orthodontic treatment. If you suspect it is caused by a disease, actively treat the relevant condition.
What methods can relieve dry mouth during sleep? Drink an appropriate amount of water before bed, but avoid overdrinking to prevent disrupting your sleep.
Use a humidifier to adjust indoor humidity. Try to correct the habit of mouth breathing, and you can use an oral appliance for assistance.
For dry mouth caused by diseases, treatment should be carried out under a doctor’s guidance according to the cause, such as controlling blood sugar or treating Sjögren’s syndrome.
