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.

Via a recent Instagram post, pop diva Ariana Grande became the latest young celebrity to publicly acknowledge a dental milestone: having her wisdom teeth removed. The singer of hits such as “Break Free” and “Problem” posted an after-surgery picture of herself (wearing her signature cat-eye eyeliner), with a caption addressed to her teeth: “Peace out, final three wisdom teeth. It’s been real.”
With the post, Grande joined several other celebs (including Lily Allen, Paris Hilton and Emile Hirsch) who have shared their dental surgery experience with fans. Will "wisdom teeth removal" become a new trending topic on social media? We aren’t sure — but we can explain a bit about the procedure, and why many younger adults may need it.
Technically called the “third molars,” wisdom teeth usually begin to emerge from the gums between the ages of 17 and 25 — presumably, around the same time that a certain amount of wisdom emerges. Most people have four of these big molars, which are located all the way in the back of the mouth, on the left and right sides of the upper and lower jaws.
But when wisdom teeth begin to appear, there’s often a problem: Many people don’t have enough space in their jaws to accommodate them. When these molars lack sufficient space to fully erupt (emerge), they are said to be “impacted.” Impacted teeth can cause a number of serious problems: These may include pain, an increased potential for bacterial infections, periodontal disease, and even the formation of cysts (pockets of infection below the gum line), which can eventually lead to tooth and bone loss.
In most cases, the best treatment for impacted wisdom teeth is extraction (removal) of the problem teeth. Wisdom tooth extraction is a routine, in-office procedure that is usually performed under local anesthesia or “conscious sedation,” a type of anesthesia where the patient remains conscious (able to breathe normally and respond to stimuli), but is free from any pain or distress. Anti-anxiety medications may also be given, especially for those who are apprehensive about dental procedures.
So if you find you need your wisdom teeth extracted, don’t be afraid to “Break Free” like Ariana Grande did; whether you post the results on social media is entirely up to you. If you would like more information about wisdom tooth extraction, please call our office to schedule a consultation.
