What are the causes of increased salivation?

hypersalivation causes

Feeling of discomfort in humans is caused by any significant change in the amount of saliva in the mouth. Sometimes it’s not paid attention to. However, such phenomena can be a symptom of serious problems in the body, so a visit to the doctor is a must.

Too much saliva has a special term – hyper salivation.


The saliva is produced by special glands. Therapeutic norm is to develop fluid in an amount of 2 ml in ten minutes. The patient may complain of hyper activation of the secretory function of salivary glands already at 5 ml. In the mouth, there is always too much of fluid and there appears a reflexive desire to swallow it.

In some cases, this problem may be associated with inflammation in the oral cavity, all possible injuries, a tongue in particular. At the same time, a feeling of fullness of the liquid in the oral cavity is false since saliva is normal.

The same feeling symptomatic, are not justified by dysfunction of the salivary glands may also occur in patients who suffer no from dental or neurological problems, but are a subject to obsessive-compulsive disorder.

In some cases, hyper salivation may be accompanied by a change in taste senses – too strong or weak sensitivity, distortion of the sense of taste, and so on. Nausea sometimes adds when the amount of saliva is bigger.


Why is strongly saliva in adultsCauses of increased salivation in both men and women can be very different. It is difficult to list them all, for the most part, it is triggered by internal problems and changes:

  • Inflammation or swelling of the salivary glands themselves.
  • Mechanical stimulation. These may be dentures, dental and manipulation activities, chewing gum, candy, and any debrides that can cause irritation in the mouth.
  • Oral trauma. These are mechanical injuries (cuts, bounces, etc.), and thermal and chemical burns.
  • Dental disease. This refers to all kinds of problems with the oral cavity – stomatitis, gingivitis, inflammation, and infectious diseases.
  • Therapeutic diseases that affect the upper respiratory organs – a sore throat, bronchitis, pleurisy, viral and respiratory diseases, increased intracranial pressure.
  • Diseases associated with damage or disorder of the gastrointestinal tract – gastritis, chronic and acute, duodenal ulcer and gastric finding esophageal debris, the occurrence of tumors in the stomach, gall bladder disease.
  • Irritation of the vagus nerve in gastritis and might also not only trigger hyper salivation, in which case it is often accompanied by nausea and vomiting.
  • Sea sickness, pregnancy, problems with the vestibular system and so on.
  • Infectious disease – encephalitis, meningitis, tuberculosis and others.
  • Quite a large number of neurological disorders – Parkinson’s disease, cerebral palsy, bulbar and pseudobulbar syndromes and more.
  • Psychogenic hyper salivation. It is almost impossible to identify the root cause, although symptoms may dramatically various – be sure to wear a container to collect saliva. In this pathology changes in the nervous system are not detected.
  • Therapeutic or drug hyper salivation. Some medications and pharmaceuticals, which the patient is forced to take to resolve the underlying disease, may also lead to an increased release of saliva.

    Mostly such drugs are heart medications, which contain muscarine, pilocarpine, physostigmine, digitalis and other alkaloids. This is almost never a serious problem, as the phenomenon disappears after dose reduction or pause of medication intake.

  • The paralysis of the facial muscles. In this case, increased production of saliva is accompanied by involuntary expiration from a mouth, which is called ptyalism.

In some cases, hyper salivation is difficult to explain. Its cause may be hormonal disorders such as symptomatic menopause, stress and increased nervousness in completely healthy people.

In children

excessive salivation in a childFor children in the first year of life in general hypersalivation is not worth attention to the problem – it is a normal process in a healthy child’s body. Here at the forefront goes a reflex factor.

When teething, especially the first, milk teeth, when the gum has not been subjected to such tests, too much saliva, too, is not a pathological condition and does not require any medical intervention. Temporarily it may happen again when wisdom teeth are cut.

However, older children should not suffer from hypersalivation. If the problem occurs, it may be due to cerebral tissue injury due to shock and other diseases or injuries of the nervous system. It is necessary to consult a specialist.

Around three months the baby starts functioning salivary glands. It is especially then a strong salivation develops. However, in this case, ptyalism is not a medical problem, because babies some time definitely need to just learn to swallow saliva.

Another factor that causes hypersalivation is a part of the defense system of the little body. With the saliva flowing derived bacteria and infection go from the mouth. In addition, an abundance of liquids helps to soften and ease the eruption of the first tooth.

In very rare cases increased salivation in children may be a symptom and a consequence of brain damage, which occurred even in the perinatal period. This may be a consequence of a very difficult birth or postnatal injury.

In pregnancy

The body of pregnant women undergoes strong changes. For the most part, this is due to hormonal changes in general. In the early stages, (most often in the first three months) of pregnancy signs of hypersalivation may show up.

Usually, this phenomenon is accompanied by early toxipathy. If a pregnant has strong nausea, sometimes vomiting, then most likely, it will be observed at increased salivation, possibly drooling.

Sometimes this is completely unrelated to the real revitalization of the salivary glands. Just trying to suppress the approaching nausea and alleviate their condition, the woman begins to unconsciously swallow less. Therefore, there is a feeling that the saliva becomes larger.

Often pregnant condition worsens due to the appearance of cardialgy. Then the body gets the signal to mitigate the effect of acid with the help of saliva, which due to the content of bicarbonate refers to alkaline medium.

Also, hypersalivation during pregnancy can be caused by the same factors as in the other adults. It is, therefore, desirable to tell your doctor, to exclude certain of these factors.

Strong night hypersalivation

During sleep, the work of the salivary glands should be significantly slowed down. Sometimes it happens that in the state of wakefulness gland return before people wake up. This leads to self-draining of fluid from the mouth of a sleeping.

If such cases are rare, there’s no reason to worry about the health. This can be caused by the temporary malfunction or common factors that do not require specialist intervention. However, the regular recurrence of this phenomenon requires a consultation with a doctor.

Sometimes, during a very deep sleep, there is a temporary loss of control over the body and reflexes, then, there may be a leakage of saliva, which is not any deviation.

It may be triggered by chronic or just long disease, in which there are nasal congestion and breathing problems such as colds or viral. Hypersalivation usually goes away after the disappearance of reasons – difficulty breathing at night.

Another factor, the presence of which may lead to hypersalivation is malocclusion. This problem can be solved by the competent dental intervention, as well as the absence of teeth, which leads to further change in the position of the rest and a change of occlusion.

salivation at night treatmentAn appropriate treatment can be discussed only after the identification of the causes of hypersalivation. The determination of what is the main factor it is not always possible: sometimes it can be solely psychological reasons, but in most cases it is still possible.

First of all it is necessary to consult a doctor-therapist. He’s already on the results of inspection and analysis can guide you to the doctors with narrower specialization.

Depending on the underlying cause professionals can prescribe treatment, associated with it, that is not being treated from hypersalivation itself, but to resolve the problem, which led to its emergence. It may be dental, gastrointestinal, neurological, or other methods.

Sometimes, in particularly critical cases, doctors can assign specific treatment, acting on the salivation only:

  • Holinolitic agents (scopolamine, Riabal, platifillin and others). They suppress excessively strong saliva production.
  • Removal method (partly) of the salivary glands. This can lead to malfunctions of the facial nerve in some cases.
  • For scarring and destruction of the salivary ducts, radiation therapy can be assigned, which greatly affects the tooth enamel.
  • When neurological disorders sometimes massage of a face and exercise therapy are assigned.
  • To temporarily block the excessive work of the salivary glands, they can do injections of botulinum toxin.
  • Cold treatment – cryotherapy – can enhance the reflex swallowing saliva.

In addition to conventional drugs, some homeopathic drugs are also used. However, their reception is necessary to agree with the doctor.
