Normal saliva flow is based upon complicated chemical and nerve reactions. When the mouth or taste buds are stimulated and or smell is stimulated, the body produces or shuts off saliva production.

 Functions of Saliva

There are many things that saliva does for us. It keeps the mouth from being too acidic which can cause cavities. It functions to remove food debris, lubricate the tissues, prevent wounds, and it is antimicrobial to boot.

 Problems due to xerostomia

Anything that impairs the functions of sailva, will cause problems. Tooth decay can soar in the mouths of people without healthy saliva. Dry foods can be difficult to eat and glands that produce salivaswallowing in general may be tough. Oral ulcers and oral fungal infections, like candidiasis may flourish. Bad breath is likely to be more common as saliva plays an important role is cleansing the body of dead tissue that add to the volatile sulfur compounds (VLC’s) responsible for bad breath.

They include diuretics, antihistamines, anorexiants, antihypertensives, antipsychotics, anti-Parkinson agents, anticholinergics, antidepressants, and sedatives. Other drug classes that commonly cause xerostomia include antiemetics, antianxiety agents, decongestants, analgesics, antidiarrheals, bronchodilators and skeletal muscle relaxants.

 Oral Cancer and radiation therapy

Radiation as a way of treating cancer cells in the mouth, can cause permanent damage to salivary cells impairing the ability to produce saliva. Often these patients will describe a thick ropey saliva and a difficulty with swallowing. Occasionally the damage is temporary and sometimes there is an improvement over time. Oral Hygiene is critical for these patients.
