Dry Mouth (Xerostomia)

Dental Surgery

What is Xerostomia?

Xerostomia is characterized by a lack or reduced flow of saliva. Saliva is secreted by numerous large and small salivary glands located in the mucous membranes of the tongue, cheeks, and palate.

Causes of Xerostomia

  • Xerostomia can occur at any age. Various diseases, treatments, radiation, and immune system disorders are among the primary causes.
  • Many medications are known to cause dry mouth.
  • Conditions such as Sjögren’s syndrome, gland obstruction or infection, glandular aplasia, and radiation therapy contribute to xerostomia.
  • Other contributing factors include dehydration, diabetes, hypertension, thyroid disorders, hormonal imbalances, Parkinson’s disease, anemia, sialolithiasis, depression, anxiety, cardiovascular issues, and the use of diuretics.

Symptoms of Xerostomia

  • Dry and smooth mucous membranes, inflammatory fissures on the tongue, and microbial plaque
  • Burning sensation in the mouth, glossitis, stomatitis, mouth ulcers, and difficulty speaking
  • Changes in taste and smell are also common symptoms
  • Increased dental plaque and periodontitis
  • Difficulty swallowing and altered taste perception
  • A significant reduction in the natural protective function of saliva, leading to severe demineralization of the teeth
  • Patients with dentures often experience retention problems

Prevention and Treatment

Preventing xerostomia is usually not possible, as it is often a side effect of necessary medical treatments, such as medication use. Therefore, efforts focus on managing its symptoms.
