What causes drooling while sleeping?

In real life, many people drool while sleeping. Frequent drooling while sleeping can not only easily lead to oral diseases, but also easily affect normal sleep. There are many reasons for drooling while sleeping. Generally, it is due to excessive saliva secretion caused by periodontitis or gastrointestinal diseases. Dental deformities can also easily lead to drooling while sleeping.

What causes drooling while sleeping?

1. Poor oral hygiene

The temperature and humidity in the mouth are most suitable for the reproduction of bacteria. The accumulation of food residues or sugar substances in the gaps between teeth and on the tooth surfaces can easily lead to caries and periodontal disease.

Inflammation in the mouth increases saliva secretion. If the mouth is infected by bacteria, there will be obvious pain and drooling. Local medication is needed to promote ulcer healing and the drooling will disappear automatically.

If you drool while sleeping, the drool tastes salty, and your pillowcase is light yellow, it is most likely due to poor oral hygiene, accumulation of food residues, and excessive tartar over time, which can cause gingivitis and even a small amount of bleeding gums.

2. Anterior Teeth Deformity

Dental deformities can also cause drooling while sleeping. Especially for patients with convex tooth deformity, the front teeth protrude more obviously, and the lips are often open and the teeth are exposed. It is difficult for the lips to completely cover the front teeth when sleeping, and the upper and lower lips often separate naturally, which makes it easy to drool. It is best for such patients to correct their teeth as soon as possible.

Three neuroregulatory disorders

In addition to the above-mentioned oral problems, some systemic diseases may also cause drooling while sleeping. The regulation of saliva secretion is completely neuroreflexive. The so-called "looking at the plum to quench thirst" is an example of conditioned reflex saliva secretion. Therefore, disorders in neural regulation may also cause drooling while sleeping. Some patients with neurosis or other systemic diseases that may cause autonomic nervous system disorders may experience abnormal excitement of the parasympathetic nerves during sleep, which can cause the brain to send erroneous signals and lead to increased saliva secretion.

Four drug factors

In addition, one of the side effects of taking certain anti-epileptic drugs is drooling, so you need to be careful when choosing drugs.

What to do when you drool while sleeping

Ways to prevent drooling while sleeping: first, pay attention to oral hygiene, and develop the habit of brushing teeth in the morning and evening, and rinsing mouth after meals; second, you can ask a dentist for treatment to eliminate tartar, gingivitis and other diseases; third, correct sleeping posture to reduce adverse stimulation to the oral cavity.
