My mouth is constantly dry. What can it be?

Expert answer:

A dry mouth may be a sign that the body is not producing enough saliva. Its main causes are: use of medication, little water intake, nervousness or stress, aging and radiation treatments.

THE xerostomia, a medical term for "dry mouth", can cause problems for oral health, since saliva helps protect teeth against cavities, prevents infections, acts on food digestion and promotes chewing and swallowing.

In addition, dryness in the mouth can cause discomfort to use prosthetic, loss of taste, bad breath, dry lips, difficulty speaking, chewing and swallowing food, burning sensation on the tongue, dry throat, metallic taste in the mouth and still sore in the mouth.

O treatment for dry mouth is to identify the cause and correct it or remove it from the patient. Not being possible, as in cases of radiation treatments or medications, the treatment is only intended to ease the symptoms.

Among the measures indicated to treat the problem are the use of chewing gum or sugarless bullets to stimulate salivation, increase water consumption, use of artificial saliva and lip lubricant, and changes in diet. To reduce the risk of caries, local application of fluoride may be indicated.

The dentist is the right professional to diagnose and treat xerostomia.
