Dry Mouth Syndrome: Xerostomia

Xerostomia (dry mouth) is not a condition everyone should expect.  You may notice it as you age due to a change in hormones, medication, and/or radiation therapy in the head and neck region.

Why Xerostomia Is a Problem
Saliva is important to oral health for several reasons.  The flow of saliva helps clear debris from the oral cavity.  It provides minerals neccessary to support the process of remineralization.  Tooth enamel daily undergoes acid attack that removes inorganic minerals from teeth.  This is called demineralization.  Remineralization is the opposite of demineralization.  It occurs when inorganic molecules flow into a region of weakened enamel and make it stronger.

When the salivary flow is reduced, a chain of events occurs.  The natural cleansing action is diminished, as are the buffering action and remineralization properties of saliva.  People with diminished salivary flow experience a very fast rate of decay, many times faster and over several teeth.  This type of decay is typically found along the gumline, around dental work that already exists, and on exposed root surfaces.

You can help prevent dental decay that can result from xerostomia.
  • Brushing and flossing correctly at least once each day becomes very important. (See This Post)
  • Frequent sips of water during the day can help moisten the mouth and can help clear debris.
  • Daily use of a mouthrinse containing fluoride can help remineralize the teeth.

  • Use a toothpaste containing sodium fluoride.
  • We recommend a daily brushing with a prescription, high-concentration sodium fluoride gel or paste.  We will either dispense this or give you a prescription for it.

  • Chew sugarless gum or a rubber band to help stimulate salivary flow.
  • In moderate to severe cases, special fluoride delivery trays can be made for you to use at home.  These will keep the high-concentration fluoride in a position to "soak" your teeth with fluoride for several minutes at a time.
  • We recommend that you have your teeth cleaned, polished, and an office-applied topical fluoride treatment every 3 months while the condition persists.
Dry mouth can have serious dental consequences and must be treated accordingly.

  4. Thanks for the post. Dental insurances are very popular in USA. But sometimes these insurances alone cannot cover all the dental treatment expenses. Dental discount plans OH are very helpful to cover the investigation cost as well.
