While it doesn’t garner the star power of blood, saliva is still an important bodily fluid. A true multi-tasker, saliva contributes in many ways to the function and health of the body, from stronger teeth to more efficient digestion.
Here are six ways saliva helps your mouth and body function properly and stay healthy.
The mouth’s natural cleanser. Bacteria are responsible for much of the dental disease that plagues us, particularly tooth decay and gum disease. Saliva clears the mouth of food remnants, bacteria’s primary feeding source, after we eat. This leaves a cleaner mouth and fewer bacteria to cause infection.
The immune system’s partner. Saliva contains an antibody called Immunoglobulin A (IgA) that attacks disease-causing microorganisms. Along with secreting other antibacterial agents like lactoferrin and lyzozyme that curb the growth and development of bacteria, saliva serves as the body’s first line of defense against pathogens entering through the mouth.
Acid neutralizer. The optimal oral environment is a neutral pH of 7. Many of our foods and beverages, though, are highly acidic, which can raise the mouth’s acid level. The acidic environment causes the minerals in tooth enamel to soften and dissolve (a process called de-mineralization). Saliva restores the balance by neutralizing any remaining acid after we eat (a process that takes about 30 to 60 minutes).
Mineral replacer. Even under normal conditions, enamel will de-mineralize to some extent whenever the mouth becomes acidic. Saliva restores some of the enamel’s lost minerals like calcium and phosphate while it’s neutralizing acid. If fluoride is also present in saliva from fluoridated drinking water or toothpaste, it too is absorbed by the enamel making it stronger and more resistant to acid attacks.
Digestion enhancer. Saliva lubricates the mouth while we eat, making it easier for us to chew (and taste) our food. Saliva also releases the enzyme amylase as we chew to break down starches before the food enters our stomach. The end result is more efficient and comfortable digestion.
The wave of the future in diagnostics. Like blood and urine, saliva contains genetic and disease markers that could tell a physician if a patient has a certain condition. Since collecting a saliva sample is much easier than with these other bodily fluids, diagnosing disease with saliva will become more prevalent as more calibrated devices reach the market.

Even though coronavirus lockdowns have prevented TV hosts from taping live shows, they're still giving us something to watch via virtual interviews. In the process, we're given occasional glimpses into their home life. During a Tonight Show interview with Seahawks quarterback Russell Wilson and his wife, R & B performer Ciara, Jimmy Fallon's daughter Winnie interrupted with breaking news: She had just lost a tooth.
It was an exciting and endearing moment, as well as good television. But with 70 million American kids under 18, each with about 20 primary teeth to lose, it's not an uncommon experience. Nevertheless, it's still good to be prepared if your six-year-old is on the verge of losing that first tooth.
Primary teeth may be smaller than their successors, but they're not inconsequential. Besides providing young children with the means to chew solid food and develop speech skills, primary teeth also serve as placeholders for the corresponding permanent teeth as they develop deep in the gums. That's why it's optimal for baby teeth to remain intact until they're ready to come out.
When that time comes, the tooth's roots will begin to dissolve and the tooth will gradually loosen in the socket. Looseness, though, doesn't automatically signal a baby tooth's imminent end. But come out it will, so be patient.
Then again, if your child, dreaming of a few coins from the tooth fairy, is antsy to move things along, you might feel tempted to use some old folk method for dispatching the tooth—like attaching the tooth to a door handle with string and slamming the door, or maybe using a pair of pliers (yikes!). One young fellow in an online video tied his tooth to a football with a string and let it fly with a forward pass.
Here's some advice from your dentist: Don't. Trying to pull a tooth whose root hasn't sufficiently dissolved could damage your child's gum tissues and increase the risk of infection. It could also cause needless pain.
Left alone, the tooth will normally fall out on its own. If you think, though, that it's truly on the verge (meaning it moves quite freely in the socket), you can pinch the tooth between your thumb and middle finger with a clean tissue and give it a gentle tug. If it's ready, it should pop out. If it doesn't, leave it be for another day or two before trying again.
Your child losing a tooth is an exciting moment, even if it isn't being broadcast on national television. It will be more enjoyable for everyone if you let that moment come naturally.

Tooth decay is more prevalent than diseases like cancer, heart disease or influenza. It doesn't have to be—brushing with fluoride toothpaste, flossing, less dietary sugar and regular dental cleanings can lower the risk of this harmful disease.
Hygiene, diet and dental care work because they interrupt the disease process at various points. Daily hygiene and regular dental cleanings remove dental plaque where oral bacteria flourish. Reducing sugar eliminates one of bacteria's feeding sources. With less bacteria, there's less oral acid to erode enamel.
But as good as these methods work, we can now take the fight against tooth decay a step further. We can formulate a prevention strategy tailored to an individual patient that addresses risk factors for decay unique to them.
Poor saliva flow. One of the more important functions of this bodily fluid is to neutralize mouth acid produced by bacteria and released from food during eating. Saliva helps restore the mouth's ideal pH balance needed for optimum oral health. But if you have poor saliva flow, often because of medications, your mouth could be more acidic and thus more prone to decay.
Biofilm imbalance. The inside of your mouth is coated with an ultrathin biofilm made up of proteins, biochemicals and microorganisms. Normally, both beneficial and harmful bacteria reside together with the “good” bacteria having the edge. If the mouth becomes more acidic long-term, however, even the beneficial bacteria adapt and become more like their harmful counterparts.
Genetic factors. Researchers estimate that 40 to 50 hereditary genes can impact cavity development. Some of these genes could impact tooth formation or saliva gland anatomy, while others drive behaviors like a higher craving for sugar. A family history of tooth decay, especially when regular hygiene habits or diet don't seem to be a factor, could be an indicator that genes are influencing a person's dental health.
To determine if these or other factors could be driving a patient's higher risk for tooth decay, many dentists are now gathering more information about medications, family history or lifestyle habits. Using that information, they can introduce other measures for each patient that will lower their risk for tooth decay even more.
