Why Spit is Important

The mouth or the oral cavity is the first stop in the human gastrointestinal tract. It is the area that receives the food. Inside the mouth are the salivary glands, which is an important fluid that aids in the process of digestion. 98% of human saliva is composed of water, while the remaining amount is made up of other compounds.

In the initial stage of digestion, saliva is produced to break down some of the fat and starch in the food. Saliva contains some enzymes that enable the breakdown of these food components. It also helps in enabling people to experience the different tastes of food.

Saliva also has antibacterial compounds. These compounds break down some of the food that is stuck in the teeth; this helps protect the teeth from bacteria that cause cavities and decay. Salivary fluids also lubricate the parts inside the mouth, like the teeth and tongue.

When a person experiences dry mouth due to lack of saliva, he is said to have xerostomia. Xerostomia can be caused by low production of saliva, or by excessive breathing through the mouth. Low saliva production can be a symptom of other underlying diseases that affect the salivary glands. It can also be a side effect of certain drugs and medications. A dentist Jackson, Tennessee has may warn that xerostomia itself can be a cause of some oral health problems.

Insufficient production of saliva can cause difficulty in eating, swallowing and speaking. A person with a dry mouth may experience frequent thirst, and a dry feeling in the throat; in some cases, it can even be a bit painful. The teeth, tongue, gums, and other oral tissues may be more susceptible to some diseases. A dentist in Jackson, TN would tell his patients that a lack of salivary fluids can, for instance, increase the risk of developing dental caries and gum diseases.

Sores in the mouth, cracked or dry lips, bad breath or halitosis can also be experienced by a person with xerostomia. If it is not caused by other physiological diseases, xerostomia may be treatable. A dentist in Jackson may recommend that a person with a dry mouth should drink plenty of water and liquids to keep the mouth moist. Chewing or sucking on sugarless gum or candy can also help stimulate the salivary glands.
