Why does the mouth dry?

Our saliva moisturizes and cleanses the oral cavity, promotes the digestion of food, inhibiting the growth of fungi and bacteria, prevents the possibility of infection. We feel a lack of saliva as discomfort and dryness. But why the mouth dries and is it possible to somehow fight this?

Why dries in the mouth:

  • due to the side effects of certain drugs (antiallergic, painkillers and coughs, tranquilizers, antidepressants; drugs used in the treatment of epilepsy or obesity);
  • this is a manifestation of certain infections or diseases (rheumatoid arthritis, cystic fibrosis, anemia, diabetes, Alzheimer's disease, HIV / AIDS, Shergen syndrome, mumps, stroke, Parkinson's disease, hypertension);
  • This is a side effect of certain therapies (chemotherapy, radiation therapy for cancer of the head);
  • due to dehydration (burns, blood loss, diarrhea, vomiting, excessive sweating, high fever);
  • due to surgical removal of the salivary glands;
  • This is a manifestation of lifestyle - chewing or smoking tobacco reduces saliva production, which exacerbates the feeling of dryness.

Signs of insufficient moisture:

  • dryness and stickiness in the mouth;
  • cracks in the corners of the mouth and lips, irritated places on the oral mucosa;
  • increased thirst;
  • itching or burning of the mouth;
  • dry throat;
  • difficulty swallowing and chewing, taste, speech;
  • redness, roughness and dryness of the tongue;
  • the appearance of bad breath;
  • sore throat, dryness on the mucous membrane of the nasal passages, hoarseness.

The consequence of dry mouth can be the development of infections of the oral cavity, caries, gingivitis.

How to deal with it

If you suspect that dryness is caused by medication, the question of why the mouth dries at night can be discussed with your doctor. He will change the prescription, may recommend rinsing his mouth, prescribe a drug that stimulates salivation. Others that can increase the production of saliva include taking a significant amount of water, chewing gum or “sucking” lozenges, preventing dental diseases, moistening the bedroom with evaporators.In some cases it is necessary to use non-prescription saliva substitutes, it is useful to develop the habit of breathing more with the nose.
