1. What is the physiology of oral factors?

1, breathe through your mouth

When the nose doesn't get enough oxygen, people can't help but start breathing through their mouths, and saliva will easily burst out.

2. Tooth protrusion

If the front teeth protrude forward obviously, the lips can't completely cover the tooth surface when sleeping, which will easily lead to saliva flowing out of the mouth.

Two. Other factors

1, material side effects

Some drugs may have the side effect of increasing saliva, such as central nervous system inhibitors. Sometimes drinking can have a similar effect.

2. Sleeping posture

When you sleep on your stomach or side, your chin will unconsciously open and saliva will easily flow out of your mouth.

Three. Pathological factors

1, oral infection

The most common infection and inflammation of oral periodontal tissue and mucosal tissue stimulates salivary gland secretion, which increases saliva secretion.

2, digestive tract diseases

Various digestive tract diseases that cause acid reflux can also stimulate abnormal saliva secretion, causing drooling during sleep.

3. Other diseases

Some patients with neurosis or other systemic diseases that may cause autonomic nerve disorders will also have abnormal excitement of parasympathetic nerves during sleep, causing increased saliva secretion.

Why does the saliva stink?

Most of them are due to poor oral hygiene, the smell produced by the accumulation and fermentation of food residues or sugar substances between teeth and tooth surfaces, or tartar, which leads to gum inflammation and odor.

What should I do if I drool when I sleep?

1. If the symptoms of drooling are caused by oral periodontal disease, you need to go to the stomatology department for corresponding treatment.

2. If there is a problem with the digestive tract, you need to go to the Department of Gastroenterology to actively treat digestive system diseases.

3. Rinsing your mouth and brushing your teeth before going to bed and doing a good job in oral hygiene are also important measures to control involuntary drooling.

4. You can sleep with a towel.
