4 reasons why you drool while sleeping

Drooling while sleeping may be caused by improper sleeping posture, such as sleeping on the table or sleeping on your side, which can easily cause drooling. But if this continues for a long time, it may be caused by some physical illness and requires attention. Four factors can cause 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.

3. 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.

4. 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.
