The Power of Saliva: Understanding it’s Importance


Saliva is often thought of as a mere byproduct of the mouth, something to be spit out or swallowed without much thought. But this clear, watery substance plays a vital role in our overall health and well-being. In this article, we’ll explore the many functions of saliva, from its role in the digestive process to its ability to protect our teeth and gums. We’ll also look at some of the latest research on saliva and its potential therapeutic uses.

The Basic Functions of Saliva

Saliva is produced by glands in the mouth and is composed mostly of water, electrolytes, and enzymes. It plays several key roles in the body, including:

  • Moistening and lubricating the mouth: Saliva helps keep the mouth moist, which makes it easier to speak, eat, and swallow. It also acts as a lubricant, which can help prevent dental problems such as tooth decay and gum disease.
  • Digestion: Saliva contains enzymes that begin the process of breaking down food in the mouth. The enzymes amylase and lipase start breaking down carbohydrates and fats, respectively, making it easier for the stomach and small intestine to continue the process.
  • Protection: Saliva contains antibodies and other substances that help defend the mouth against bacteria and viruses. It also helps neutralize acids produced by plaque, which can cause tooth decay.

The Latest Research on Saliva

Recent studies have shown that saliva may have even more functions than previously thought. For example, researchers have found that:

  • Saliva may have anti-inflammatory properties: Studies have shown that saliva contains molecules that can suppress inflammation. This may help explain why saliva is effective in treating conditions such as dry mouth and oral thrush.
  • Saliva may have therapeutic uses: Saliva contains a wide range of biomolecules, including hormones, growth factors, and other signaling molecules. Some researchers believe that these substances could be used to develop new treatments for various diseases.
  • Saliva may be a diagnostic tool: Saliva contains a wealth of information about a person’s health, including DNA, proteins, and other biomolecules. Scientists are working on developing new tests that can detect diseases such as cancer and diabetes using saliva samples.

Keeping Your Saliva Healthy

While saliva is an essential substance, there are steps you can take to maintain healthy saliva production and protect your oral health. These include:

  • Drinking plenty of water: Saliva is mostly water, so it’s important to stay hydrated to keep your saliva flowing.
  • Chewing sugar-free gum: Chewing gum can stimulate saliva production, which can help protect your teeth and gums.
  • Avoiding tobacco and excessive alcohol: Both of these substances can dry out the mouth and reduce saliva production.
  • Maintaining good oral hygiene: Brushing and flossing your teeth regularly can help remove plaque and bacteria that can harm your saliva.

Saliva may not seem like a particularly interesting or important substance, but it plays a vital role in our overall health and well-being. From moistening and lubricating the mouth to protecting against bacteria and viruses, saliva is essential for maintaining good oral health. And with new research showing that saliva may have therapeutic and diagnostic uses, this often-overlooked substance is worth paying more attention to. By keeping your saliva healthy, you can help protect your overall health and well-being.
