Saliva is a thing that everyone takes for granted….until it’s gone! This ingenious liquid produced by a healthy human body serves many purposes.
Besides it’s 99.5 % water content, saliva also contains substances that are important to keep the gingiva, teeth and tongue healthy and comfortable. It aids in swallowing, speech, and our ability to taste food. It even begins the digestive process.
The remaining composition of saliva includes mucus, which is the lubricant. Amylase begins the digestion of starches; lipase is an enzyme that starts the breakdown of fats. All of this is in an electrolyte solution that helps to moisten the food we eat. Antibacterial compounds are also in saliva in small amounts to protect us from certain bacteria. Saliva even keeps our teeth protected from decay by cleansing away food debris. Without saliva everything will stick to the teeth and gums increasing the chance of decay and gum inflammation.
Saliva is produced more when we chew by glands located in the cheeks and under the tongue. There are six major glands and hundreds of accessory glands. Saliva is deposited into the mouth thru ducts. Although everyone is different, the body will produce two to four pints of saliva per day with the majority flowing in the late afternoon and slowing to very little during sleep.
Dry mouth, or xerostomia, is a condition where the mouth’s salivary glands do not produce enough saliva to keep the mouth moist. Dry mouth is usually caused as a side effect of common medications such as decongestants, antihistimines, and high blood pressure meds. Medications, either over the counter or prescription can inhibit the body’s production of saliva or change its composition or consistency. Certain medical conditions such as Sjogren’s Syndrome, HIV/AIDS, diabetes and Parkinson’s Disease can lead to dry mouth. Chemotherapy and radiation therapy can cause xerostomia depending on the area of the body being treated. Even just simple dehydration can make the mouth dry and uncomfortable.
Combating dry mouth is a constant battle especially if one has to continue taking medications that cause it. Sipping on water throughout the day can keep the mouth more comfortable. Chewing sugar free gum or sucking on special mints that contain Xylitol can aid the salivary glands to extrude more saliva. Oral rinses and artificial saliva can be found over the counter to replace a small amount of moisture. Substitute saliva does not contain the important proteins, minerals and enzymes of natural saliva but it can help with the uncomfortable feeling of dry mouth.
