DRY MOUTH


Dry mouth or xerostomia is a term used to describe the absence or reduced flow of saliva. This is a very uncomfortable condition as saliva plays a very important role having many functions:

  • Acts as a cleansing agent

Causes of dry mouth

  • A variety of medicine causes dry mouth as a side effect. These include decongestants and antihistamines used to treat allergies and colds; sedatives and muscle relaxants. Bronchodilators used in the treatment of asthma, diuretics. Other drugs used to treat depression, Parkinsonism, diarrhea and nausea also have a similar effect.
  • Dry mouth is a common manifestation in people suffering from AIDS, mumps, Alzheimer’s disease, Sjogren’s syndrome, Parkinson’s disease, rheumatoid arthritis, cystic fibrosis, diabetes, anemia, stroke and hypertension.
  • Xerostomia is a common feature in patients who have undergone chemotherapy and radiation for head and neck cancers. This occurs when the salivary glands which produce saliva are damaged.
  • Also occurs when the salivary glands are removed as in case of cancer etc and dry mouth results.
  • Nerve damage to those supplying the salivary glands can result in xerostomia.
  • Certain conditions such as vomiting, diarrhea, and fever, loss of blood, burn injuries, and heavy sweating can cause dehydration of the body leading to dry mouth.
  • Habits such as smoking, tobacco chewing, open-mouthed breathing also leads to dry mouth.

Treatment of dry mouth

It is best to treat the cause of xerostomia rather than its symptoms.

If you are taking any medication which causes dry mouth or feel your mouth to be dry after starting a new drug then report to your doctor who can give you alternatives or reduce the dosage to resolve the problem.

Oral rinses are prescribed for relief from symptoms of dry mouth. Commonly prescribed is “salagen” which is effective in increasing salivary production. “Biotene” dry mouth products are also available as mouth washes, toothpaste, mouth sprays etc. they contain an enzyme and protein system that supplements saliva’s natural defenses.

Some home remedies are of the following:

  • Chewing sugar-free candy or gum
  • Drinking large quantities of water
  • Keeping the mouth closed
  • Using vaporizers that moisturize the air
  • Using fluoride toothpaste and mouth rinse to help prevent the incidence of caries.
  • Salivary substitutes
  • Regular visits to the dentist.
