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.

When the multi-platinum recording artist, songwriter and TV personality Jason Derulo was recently asked about his ideal woman, his answer covered a remarkably broad spectrum. "There’s no specific thing," he said, "so I think it’s unfair to say what my ‘type’ is." But it turns out that there is one thing the So You Think You Can Dance judge considers essential: A beautiful smile.
"I’m not into messy teeth," Derulo said. "If the grill has spaces and different colors, it’s not my vibe."
As it turns out, he may be on to something: A number of surveys have indicated that a bright, healthy smile is often the first thing people notice when meeting someone new. Yet many are reluctant to open up that big grin because they aren’t satisfied with the way their teeth look. If you’re one of them, consider this: Modern cosmetic dentistry offers a variety of ways to improve your smile — and it may be easier and more affordable than you think.
For example, if your smile isn’t as bright as you would like it to be, teeth whitening is an effective and economical way to lighten it up. If you opt for in-office treatments, you can expect a lightening effect of up to 10 shades in a single one-hour treatment! Or, you can achieve the same effect in a week or two with a take-home kit we can custom-make for you. Either way, you’ll be safe and comfortable being treated under the supervision of a dental professional — and the results can be expected to last for up to two years, or perhaps more.
If your teeth have minor spacing irregularities, small chips or cracks, it may be possible to repair them in a single office visit via cosmetic bonding. In this process, a liquid composite resin is applied to the teeth and cured (hardened) with a special light. This high-tech material, which comes in colors to match your teeth, can be built up in layers and shaped with dental instruments to create a pleasing, natural effect.
If your smile needs more than just a touch-up, dental veneers may be the answer. These wafer-thin coverings, placed right on top of your natural teeth, can be made in a variety of shapes and colors — from a natural pearly luster to a brilliant "Hollywood white." Custom-made veneers typically involve the removal of a few millimeters of tooth enamel, making them a permanent — and irreversible — treatment. However, by making teeth look more even, closing up spaces and providing dazzling whiteness, veneers just might give you the smile you’ve always wanted.
