Causes of dry mouth

The Saliva is necessary to moisten and cleanse the mouth and help digest food; it also prevents infections, controlling fungi and bacteria, but when the mouth is dry, it is a very uncomfortable situation, which can be caused by the following causes:

  • Surgical removal of the salivary glands.
  • Tobacco can affect the production of saliva, which together with continuous breathing with the mouth open, especially at night, aggravates the problem.
  • Dehydration, which produces fever, excessive sweating, vomiting and diarrhea.
  • Nerves damaged in the head or neck, by surgery
  • Diseases , such as Jorgen’s syndrome, HIV / AIDS, Alzheimer’s disease, Parkinson’s disease, diabetes, anemia, cystic fibrosis, rheumatoid arthritis, hypertension, stroke and viral infections such as mumps.
  • Medical treatments, which can damage the salivary glands, such as radiation or chemotherapy.
  • Certain medications. Dry mouth is a common side effect of many medications, such as those used to treat depression, anxiety, pain, allergies and colds; as well as urinary incontinence, bronchodilators, Parkinson’s disease, sedatives and muscle relaxants.
