While oral hygiene, a nutritious diet and regular dental visits are all crucial to long-term oral health, these efforts complement what your body already does to keep your mouth healthy. One of the major players in this function is saliva.
Produced by hundreds of glands located throughout the mouth, saliva does much more than help you swallow and wash away food. As you chew, an enzyme in saliva known as amylase breaks down starches in your food to make it easier to digest in the stomach. Saliva also contains antibodies, similar to what’s in tears, which can fight bacteria and other disease-causing organisms.
Perhaps its most important function, though, is its ability to protect and maintain healthy tooth enamel. The strongest substance in the body, enamel nevertheless has one primary enemy — the acid found in certain foods or as a byproduct of bacteria feeding on sugar and other carbohydrates.
When the ideally neutral pH level of the mouth becomes too acidic (nearly every time you eat), minerals in the enamel begin to soften and dissolve. The increased saliva flow when we eat floods the mouth with buffering agents that neutralize the acid and restore the mouth’s normal pH level. Not only does saliva stop demineralization, but it also restores a good bit of the enamel’s mineral content.
In recent years, a new role for saliva has begun to emerge as a means to diagnose disease. Like blood, urine and other bodily fluids, saliva contains molecules that serve as biological markers for disease. Given the right equipment, saliva has the potential to indicate early signs of cancer (including oral), diabetes and other systemic conditions. As the means to examine saliva for these markers increases it promises to be easier and less expensive to collect and sample than blood, while reducing the chances of transmitting bloodborne diseases to healthcare workers.
It’s a lot to consider with this fluid that you hardly notice, except when it isn’t there. Saliva is proof that our efforts at keeping our mouths healthy cooperate and depend on our bodies’ amazing systems.

Fans of the primetime TV show The Middle were delighted to see that high school senior Sue, played by Eden Sher, finally got her braces off at the start of Season 6. But since this popular sitcom wouldn’t be complete without some slapstick comedy, this happy event is not without its trials and tribulations: The episode ends with Sue’s whole family diving into a dumpster in search of the teen’s lost retainer. Sue finds it in the garbage and immediately pops it in her mouth. But wait — it doesn’t fit, it’s not even hers!
If you think this scenario is far-fetched, guess again. OK, maybe the part about Sue not washing the retainer upon reclaiming it was just a gag (literally and figuratively), but lost retainers are all too common. Unfortunately, they’re also expensive to replace — so they need to be handled with care. What’s the best way to do that? Retainers should be brushed daily with a soft toothbrush and liquid soap (dish soap works well), and then placed immediately back in your mouth or into the case that came with the retainer. When you are eating a meal at a restaurant, do not wrap your retainer in a napkin and leave it on the table — this is a great way to lose it! Instead, take the case with you, and keep the retainer in it while you’re eating. When you get home, brush your teeth and then put the retainer back in your mouth.
If you do lose your retainer though, let us know right away. Retention is the last step of your orthodontic treatment, and it’s extremely important. You’ve worked hard to get a beautiful smile, and no one wants to see that effort wasted. Yet if you neglect to wear your retainer as instructed, your teeth are likely to shift out of position. Why does this happen?
As you’ve seen firsthand, teeth aren’t rigidly fixed in the jaw — they can be moved in response to light and continuous force. That’s what orthodontic appliances do: apply the right amount of force in a carefully controlled manner. But there are other forces at work on your teeth that can move them in less predictable ways. For example, normal biting and chewing can, over time, cause your teeth to shift position. To get teeth to stay where they’ve been moved orthodontically, new bone needs to form around them and anchor them where they are. That will happen over time, but only if they are held in place with a retainer. That’s why it is so important to wear yours as directed — and notify us immediately if it gets lost.
And if ever you do have to dig your retainer out of a dumpster… be sure to wash it before putting in in your mouth!
