For over a century now, health providers have depended on blood and urine samples to diagnose many forms of disease. Very soon, though, we may routinely use a different bodily fluid that's easier and cheaper to collect: saliva.
Secreted by six hundred or more glands in the mouth, saliva performs a number of important functions for digestion and overall oral health. Saliva lubricates the mouth to make food easier to swallow. Its enzymes begin the digestion process breaking down food even before we swallow. It also helps wash out food particles that could build up as plaque on the teeth and harbor disease-causing bacteria.
In terms of dental health, its greatest role is as a neutralizer of food acid. It's natural after we eat for the acid levels in the mouth to rise above normal. If acid remains in contact with enamel for an extended period of time it can soften the enamel's minerals and make it easier for them to erode. Within thirty minutes to an hour after eating, saliva neutralizes acid and restores the mouth's normal pH level. Saliva also contains calcium and phosphate materials, which helps restore some of the minerals the enamel may have lost from the acid contact.
But we're discovering saliva can do even more: we can now use it as an indicator for certain conditions in the body. Like blood or urine, saliva contains molecules that can serve as biological markers for different types of disease. By employing devices calibrated to detect these markers, we can use saliva to uncover cancer, diabetes or other systemic conditions.
As these particular devices are manufactured and become more available, the use of saliva for disease diagnosis will rise. In the future, you may not need a trip to the bathroom or wince at a needle stick — a swab of your saliva will do!

Everyone knows that in the game of football, quarterbacks are looked up to as team leaders. That's why we're so pleased to see some NFL QB's setting great examples of… wait for it… excellent oral hygiene.
First, at the 2016 season opener against the Broncos, Cam Newton of the Carolina Panthers was spotted on the bench; in his hands was a strand of dental floss. In between plays, the 2105 MVP was observed giving his hard-to-reach tooth surfaces a good cleaning with the floss.
Later, Buffalo Bills QB Tyrod Taylor was seen on the sideline of a game against the 49ers — with a bottle of mouthwash. Taylor took a swig, swished it around his mouth for a minute, and spit it out. Was he trying to make his breath fresher in the huddle when he called out plays?
Maybe… but in fact, a good mouthrinse can be much more than a short-lived breath freshener.
Cosmetic rinses can leave your breath with a minty taste or pleasant smell — but the sensation is only temporary. And while there's nothing wrong with having good-smelling breath, using a cosmetic mouthwash doesn't improve your oral hygiene — in fact, it can actually mask odors that may indicate a problem, such as tooth decay or gum disease.
Using a therapeutic mouthrinse, however, can actually enhance your oral health. Many commonly available therapeutic rinses contain anti-cariogenic (cavity-fighting) ingredients, such as fluoride; these can help prevent tooth decay and cavity formation by strengthening tooth enamel. Others contain antibacterial ingredients; these can help control the harmful oral bacteria found in plaque — the sticky film that can build up on your teeth in between cleanings. Some antibacterial mouthrinses are available over-the-counter, while others are prescription-only. When used along with brushing and flossing, they can reduce gum disease (gingivitis) and promote good oral health.
So why did Taylor rinse? His coach Rex Ryan later explained that he was cleaning out his mouth after a hard hit, which may have caused some bleeding. Ryan also noted, “He [Taylor] does have the best smelling breath in the league for any quarterback.” The coach didn't explain how he knows that — but never mind. The takeaway is that a cosmetic rinse may be OK for a quick fix — but when it comes to good oral hygiene, using a therapeutic mouthrinse as a part of your daily routine (along with flossing and brushing) can really step up your game.
