Savoring food, chewing, and swallowing it without difficulty have a very close relationship with the amount of saliva produced in the mouth. Here the well-known adage applies: all extremes are vicious. If you have little saliva and a dry mouth, it is not the normal condition. In some circumstances, you may wonder: why does your mouth produce so excessive saliva? This is a situation known as hypersalivation. This is the opposite condition of a dry mouth.
Saliva is produced in the salivary glands. Every day, a person produces between 0.75 liters and 1.5 liters of saliva. Production peaks at the time of consuming food and reaches its lowest level during sleep.
Saliva moistens food, has antimicrobial action, maintains the integrity of the oral mucosa, remineralizes the oral cavity, and helps in food intake, making it easier to swallow. In addition, it has enzymes that aid digestion. It is also useful for healing wounds, prevents dry mouth, and is a barrier to irritants and toxins.
This is the excessive saliva production associated with muscle control. It is also called sialorrhea or ptyalism. Excess saliva accumulates and comes out involuntarily through the lower lip, i.e., drooling. Drooling is normal in the first two years of life, a stage in which the control of the muscles near the mouth has not yet developed. In other phases of life, it is an indicator that it is necessary to review the problem and find the cause.
Sialorrhea can be constant, intermittent, temporary, or chronic. This depends upon what generates it. It is a symptom of an underlying health situation that can be linked to a common and easily treated cause, perhaps even a complex health condition. If the hypersalivation is the consequence of an infection, the excessive production of saliva is a reaction to eliminate bacteria, and it will disappear when this health condition resolves. Oscar Castro Reino, President of the General Council of Dentists of Spain, points out that hypersalivation is more common in people diagnosed with neurodegenerative diseases.
Different causes can lead to hypersalivation; they may be related to a temporary event or to another condition that requires treatment for a certain period.
Excessive saliva production, or sialorrhea, can be caused by seeing, smelling, or tasting food. Some people produce too much saliva when thinking about certain foods, a situation popularly expressed as “I taste”, “I pass saliva”, and/or “the mouth waters”. It also occurs when eating foods high in citric acid or sugar, and chewing gum.
Hypersalivation may be the consequence of a chronic disease that affects and impairs muscle control. If it is not treated adequately and promptly, it causes difficulty in speaking clearly and in ingesting food and drinks without choking. Plus, the sense of taste is reduced, among other effects.
A person with sialorrhea is more likely to inhale saliva, food, or fluid into the lungs, which is colloquially described as going the old way, which can lead to aspiration pneumonia. You are more likely to face this situation when your gag and cough reflexes are impaired.
The objective of the diagnosis is to identify the root of the problem,\ or the underlying cause that generates excess saliva, and later prescribe the appropriate treatment.
Diagnosis is very important, as some of the possible causes may entail careful handling.
In cases of chronic hypersalivation, symptom management is a key factor.
Some of the symptoms that are recorded due to excessive saliva production are:
In the diagnostic stage, tests may be required:
Other criteria that must be taken into account in the diagnosis:
Treatment focuses on the underlying health condition causing hypersalivation and on controlling or reducing its immediate effects.
Treatment may include therapies, medications, or home remedies, depending on the cause of the excessive salivation. You can also incorporate behavior changes, speech therapy, posture and head control, lip-locking techniques, and improved tongue control.
Medication to reduce saliva production and anticholinergic medications may be prescribed, but they will manifest various side effects: drowsiness, irritability, restlessness, constipation, urinary retention, hot flashes, and blurred vision.
Cases of chronic hypersalivation require specific treatment, depending upon the health condition that generates excessive saliva production.
Botox injections are another alternative. This substance causes muscle paralysis and causes the salivary glands to stop producing saliva. The effect will disappear a few months later.
If it is an extreme case, the treating physician may recommend surgery to remove the salivary glands or relocate them to facilitate the passage of saliva through the back of the mouth.
An alternative to surgery is radiation therapy, which relieves hypersalivation and causes dry mouth.
Although sialorrhea is not a disease but a symptom of a health condition, it is a situation that requires diagnosis promptly. If it is a temporary circumstance, it may be treated with simple therapies, but it could require complex treatment that goes beyond home care.
