What is the reason for yellow saliva

Everyone has saliva, and a lot of it is secreted every day. Normal saliva is colorless and transparent, and has no odor, so why is saliva yellow? Yellow saliva may be caused by oral disease, such as bacterial infection. If oral hygiene is not maintained well, the saliva may easily change color, so it is very important to maintain oral hygiene.

First of all, it may be due to improper sleeping posture. Sleeping on the table or sleeping on your side can easily cause drooling.

Secondly, inflammation in the mouth can also promote 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.

Dental deformity is the third cause of 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.

In addition to the above-mentioned oral problems, some systemic diseases may also cause drooling while sleeping. Some patients with neurosis or other systemic diseases that may cause autonomic nervous system disorders may also experience abnormal excitement of the parasympathetic nervous system during sleep, which may cause the brain to send erroneous signals and lead to increased saliva secretion.

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

Saliva, medically known as spit, is a colorless, transparent, foamy, slightly turbid liquid. The amount of saliva secretion is similar to that of urine, averaging about 1,500 ml per day.

Drooling while sleeping is generally caused by the following factors:

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. These adverse factors are stimulating and can cause drooling while sleeping.

2. Malformation of front teeth: This may be due to genetic factors and acquired bad habits, such as biting nails, sticking out tongue, biting pencil heads, etc., which cause deformity of front teeth and drooling while sleeping.

3. Neuroregulatory disorders: 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 in daily life. Therefore, disorders in neural regulation may also cause drooling while sleeping.

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. Therefore, the saliva that flows out while sleeping tastes salty and is light yellow in color.
