The xerostomia is a nagging feeling of dry mouth that affects the ability to enjoy some food, to swallow and, in severe cases, is also a language problem. Dry mouth may only last a few hours or even a couple of days if is linked to a transient state of nervousness, which alters the normal functions of glandular secretion.

However, when it lasts for several days or weeks, it is a symptom of disease.

The most frequent symptoms that can accompany oral dryness are:

  1. viscous and pasty saliva mouth
  2. chapped lips
  3. ulcers on the internal cavities due to movements of the mouth in the absence of lubrication
  4. infections of the mouth and on the tongue
  5. dental caries and halitosis due to lack of salivary enzymes (lipase, amylase ...)

What are the causes of dry mouth?

The xerostomia, or the sensation of dry mouth, is generally caused by an incorrect operation of the salivary glands.

The major salivary glands, parotid, submandibular and sublingual, together with numerous other minor glands are positioned in the oral cavity that have the function of production and secretion of saliva which participates in the digestive process.

This function, controlled by the parasympathetic nervous system, may be compromised by some physiological conditions such as seniority, causes no pathological or by more complex diseases, for which the flow of saliva becomes insufficient.

Not always the xerostomia is caused by an altered salivary gland function!

Among the many non-pathological causes of dry mouth, these can be included:

  • Excessive consumption of alcohol that determine dehydration of the oral cavity

  • Smoking, increases keratinization of the interior of the oral cavity. The inner walls of the mouth, in fact, thicken as a defensive measure at the entrance of the cigarette smoke that dries the natural moistness of the mouth

  • Aanxiety and stress, age

  • Taking medications such as diuretics used to treat hypertension, these drugs induce the excretion of potassium and water causing the increase in urine volume and lowering the blood. However, the massive excretion of water leads to a slight dehydration of the tissue perceived as dry feeling in the mouth. Even prolonged use of antibiotics, cortisone and NSAIDs, can cause dry mouth through the imbalance of normal bacterial flora of the oral cavity guest, more susceptible to attacks in pathogens

  • Antineoplastic therapies and immunodeficiencies, as in diseases characterized by immune deficiency also in the course of chemo therapy and radiotherapy, there is a reduction in the functionality of the immune system. This condition makes the mouth more susceptible to infections and symptoms related to xerostomia
