Often described as "cotton mouth", Dry Mouth Syndrome (Xerostomia) is a condition caused by a decrease in saliva production.  This occurs when the Salivary Glands do not function properly, leaving the mouth dry and uncomfortable.  Saliva aids in the digestion process.  It helps to protect teeth from decay, and lubricates the tongue and other tender tissues of the mouth.  It also helps to prevent infections and sores in the mouth.  Dry Mouth occurs when the salivary glands stop working effectively.   Dry Mouth can be difficult to diagnose because of the nature of the condition: what feels dry to one patient may not be no tic able to another.  Sometimes the amount of saliva may be reduced by 50% before symptoms occur.  Dentists are sometimes able to diagnose Xerostomia based on visual signs in the patient's mouth.  A Dentist may notice a thickness or lack of saliva, an increased decay rate, or cracked, dry lips.  Sometimes mouth mirrors or instruments will stick to the side of the patient's mouth.  Due to the lack of saliva flow, the patient may have an increase susceptibility to Periodontal Disease or mouth sores.   If visible signs are not present, a diagnosis can be made by talking with the patient about what they have been experiencing.

25% of patients experience Dry Mouth at some point in their life.  For some people, however, it can be a daily problem.  Patients over the age of 50 are more likely to experience Dry Mouth.  As we get older, our mouths naturally produce less saliva, and older patients tend to take more medications which have been linked to Xerostomia..

Causes of Dry Mouth

Prescription and over-the-counter medications are the most common cause of Dry Mouth, contributing to   70% of all cases.  The number of medications one takes and how they interact is also directly related to Xerostomia.  If medications are the cause of your Dry Mouth, speak with your Doctor.  It may be possible to change the medication or lower the dosage to help minimize the symptoms of Dry Mouth.  Some medications which have been shown to cause dry mouth include but are not limited to:
