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.

The vast majority of teeth and gum problems stem from two dental diseases: dental caries (tooth decay) and periodontal (gum) disease. But although these dental diseases are all too common in our society, there’s a good chance you can prevent them from harming your own dental health.
That’s because we know the primary cause for both of them—dental plaque, a thin film of bacteria and food particles that can build up on tooth surfaces usually as a result of poor oral hygiene. Remove this plaque build-up daily and you dramatically decrease your risk for disease.
The primary way to do this is with a daily habit of brushing and flossing. While regular dental cleanings remove plaque and tartar (calcified plaque) from hard to reach places, it’s your regular practice that removes the bulk of daily buildup. Interrupting plaque buildup helps keep disease-causing bacteria at bay.
That also means performing these two hygiene tasks thoroughly. For example, you should brush all tooth surfaces, especially in the rear and along the entire gum line (a complete brushing should take at least 2 minutes). And by the way, “thorough” doesn’t mean “aggressive”—a gentle circular motion is all you need. If you scrub too hard, you run the risk over time of damaging your gums.
And while many people discount flossing as a hard and unpleasant task, it’s still necessary: at least half of the plaque in your mouth accumulates between the teeth where brushing can’t reach effectively. If you find flossing too difficult, you can take advantage of tools to make the task easier. A floss threader will make it easier to get floss through your teeth; you could also use an oral irrigator, a device that emits a pressurized spray of water to loosen and flush away some plaque.
Along with dental visits at least twice a year, daily brushing and flossing is the best way to reduce your risk of both tooth decay and gum disease. Avoiding these two diseases will help ensure your smile is attractive and healthy throughout your life.

Along with thumb sucking, childhood teeth grinding is one of the top concerns anxious parents bring to their dentists. It’s so prevalent, though, many providers consider it normal behavior—the sleep-disturbing sound it can generate is often the worst consequence for the habit.
But that doesn’t mean you should brush aside all concern, especially if the habit continues into late childhood. Long-term teeth grinding could eventually damage the teeth and gums.
Teeth grinding (or clenching) is the involuntary movement of the jaws when not engaged in normal functions like chewing, speaking or swallowing. The action often produces higher than normal chewing forces, which over time can accelerate tooth wear, cause fractures, or contribute to loose teeth, all of which could increase the risk of dental disease. While it can occur at any time it’s most common among children during nighttime sleep.
While stress is the usual trigger for teeth grinding in adults, with young children the causes for the habit are more complex and less understood. Most doctors hold to the theory that most pediatric teeth grinding arises during shifts from lighter to heavier, rapid-eye-movement (REM) sleep. The child’s immature neuromuscular chewing control may engage involuntarily during this shift. Teeth grinding is also prevalent among children who snore or mouth-breathe, or who take anti-depressant medication.
But as mentioned before, there’s usually no cause for concern unless the habit persists beyond about age 11. If the habit isn’t fading, you should speak to your dentist about ways to reduce it or its effects. One way is with a custom-made night guard worn during sleep. The smooth, plastic surface of the appliance prevents teeth from making solid contact with each other during a grinding episode.
You might also seek treatment from an ear, nose and throat (ENT) specialist if your child is having issues with airway obstruction, which could also relieve teeth grinding. And children experiencing stressful situations or events may find relief both emotionally and physically from psychological therapy.
At younger ages, you can safely regard your child’s grinding habit as normal. But if it persists, it’s worth looking for ways to reduce it.
