Saliva probably doesn’t rate high on your amazement meter. You’re more likely to notice its absence and the dry irritation that results.
But you might be more impressed with this unsung bodily fluid if you knew all the things it does. It’s definitely a multi-tasker, performing a number of jobs (including aiding in digestion) that not only keep your oral health on track, but your general well-being too. And there are even new testing methods where saliva may even tell us when you’re not doing so well.
Here are 3 more tasks your saliva is doing for your mouth right now that truly makes it amazing.
Cleansing. Your teeth’s chewing action shreds food so it’s easier to digest. But that also leaves behind tiny particles in your mouth. Bacteria feast on these particles (especially carbohydrates like sugar) and produce acid as a byproduct, which can increase your risk of tooth decay. Saliva serves as a kind of “rinse cycle” for your mouth, helping to wash a good bit of these errant particles down your throat and away from hungry bacteria.
Defense. Speaking of bacteria, your mouth is home to millions of them. While most are harmless or even beneficial, a fraction can harm your teeth and gums. Saliva is your first line of defense, emitting an antibody known as Immunoglobulin A that targets these bacteria. Saliva also produces an antibacterial substance called lyzozyme that prevents bacteria from growing.
Enamel Protection. Although it’s the strongest substance in the body, your teeth’s enamel can’t withstand the effects of mouth acid, the by-product of bacterial feeding and growth. Acid levels naturally rise after eating; but even this sudden rise can begin the process of demineralization where minerals in enamel dissolve. Saliva saves the day by first neutralizing the acid and restoring the mouth’s normal pH in about thirty minutes to an hour. It also helps restore minerals in enamel, a process called remineralization. It’s all in a day’s work for this remarkable fluid.

Some people are lucky — they never seem to have a mishap, dental or otherwise. But for the rest of us, accidents just happen sometimes. Take actor Jamie Foxx, for example. A few years ago, he actually had a dentist intentionally chip one of his teeth so he could portray a homeless man more realistically. But recently, he got a chipped tooth in the more conventional way… well, conventional in Hollywood, anyway. It happened while he was shooting the movie Sleepless with co-star Michelle Monaghan.
“Yeah, we were doing a scene and somehow the action cue got thrown off or I wasn't looking,” he told an interviewer. “But boom! She comes down the pike. And I could tell because all this right here [my teeth] are fake. So as soon as that hit, I could taste the little chalkiness, but we kept rolling.” Ouch! So what's the best way to repair a chipped tooth? The answer it: it all depends…
For natural teeth that have only a small chip or minor crack, cosmetic bonding is a quick and relatively easy solution. In this procedure, a tooth-colored composite resin, made of a plastic matrix with inorganic glass fillers, is applied directly to the tooth's surface and then hardened or “cured” by a special light. Bonding offers a good color match, but isn't recommended if a large portion of the tooth structure is missing. It's also less permanent than other types of restoration, but may last up to 10 years.
When more of the tooth is missing, a crown or dental veneer may be a better answer. Veneers are super strong, wafer-thin coverings that are placed over the entire front surface of the tooth. They are made in a lab from a model of your teeth, and applied in a separate procedure that may involve removal of some natural tooth material. They can cover moderate chips or cracks, and even correct problems with tooth color or spacing.
A crown is the next step up: It's a replacement for the entire visible portion of the tooth, and may be needed when there's extensive damage. Like veneers, crowns (or caps) are made from models of your bite, and require more than one office visit to place; sometimes a root canal may also be needed to save the natural tooth. However, crowns are strong, natural looking, and can last many years.
But what about teeth like Jamie's, which have already been restored? That's a little more complicated than repairing a natural tooth. If the chip is small, it may be possible to smooth it off with standard dental tools. Sometimes, bonding material can be applied, but it may not bond as well with a restoration as it will with a natural tooth; plus, the repaired restoration may not last as long as it should. That's why, in many cases, we will advise that the entire restoration be replaced — it's often the most predictable and long-lasting solution.
Oh, and one more piece of advice: Get a custom-made mouthguard — and use it! This relatively inexpensive device, made in our office from a model of your own teeth, can save you from a serious mishap… whether you're doing Hollywood action scenes, playing sports or just riding a bike. It's the best way to protect your smile from whatever's coming at it!

The next time you visit your dentist you might see an item quite different from the other dental instruments and equipment in the office: a blood pressure cuff. Checking blood pressure is becoming a more common occurrence in dental offices across the country.
Abnormal blood pressure and some of the medications used to treat it are often a factor in some dental procedures, particularly if anesthesia is involved. But your dentist may also check your blood pressure for another reason: dental visits represent another avenue to screen for this condition that increases the risk of serious health problems.
Undiagnosed high blood pressure is a prevalent but often “silent” problem because the early stages of the condition may not display any symptoms. Many people first become aware they have an issue only after a blood pressure check at their family doctor, pharmacy or a health fair, for example. Otherwise, they could go months, even years without this vital knowledge about their health.
But while people may only visit their doctor once a year (or less) many see their dentist much more often, even twice a year, for routine cleanings and checkups. Including blood pressure screenings as a routine part of dental treatment could alert patients to a potential issue much earlier than their next doctor’s visit.
In fact, one study published in the Journal of the American Dental Association looked at a group of dental patients with no reported heart disease risk and who had not seen a doctor in the twelve months before their dental visit. During their visit their blood pressure was checked. Of those then referred to a physician for an abnormal reading, 17% learned for the first time they had an increased risk of cardiovascular disease.
It’s estimated about 80 million Americans have some form of cardiovascular disease and many don’t even know it. Diagnosing and controlling high blood pressure is a key factor in treating these life-threatening conditions. And many dentists are joining the fight by making this simple screening method a part of their dental care services.

How many actresses have portrayed a neuroscientist on a wildly successful TV comedy while actually holding an advanced degree in neuroscience? As far as we know, exactly one: Mayim Bialik, who plays the lovably geeky Amy Farrah Fowler on CBS' The Big Bang Theory… and earned her PhD from UCLA.
Acknowledging her nerdy side, Bialik recently told Dear Doctor magazine, “I'm different, and I can't not be different.” Yet when it comes to her family's oral health, she wants the same things we all want: good checkups and great-looking smiles. “We're big on teeth and oral care,” she said. “Flossing is really a pleasure in our house.”
How does she get her two young sons to do it?
Bialik uses convenient pre-loaded floss holders that come complete with floss and a handle. “I just keep them in a little glass right next to the toothbrushes so they're open, no one has to reach, they're just right there,” she said. “It's really become such a routine, I don't even have to ask them anymore.”
As many parents have discovered, establishing healthy routines is one of the best things you can do to maintain your family's oral health. Here are some other oral hygiene tips you can try at home:
Brush to the music — Plenty of pop songs are about two minutes long… and that's the length of time you should brush your teeth. If brushing in silence gets boring, add a soundtrack. When the music's over — you're done!
Flossing can be fun — If standard dental floss doesn't appeal, there are many different styles of floss holders, from functional ones to cartoon characters… even some with a martial-arts theme! Find the one that your kids like best, and encourage them to use it.
The eyes don't lie — To show your kids how well (or not) they are cleaning their teeth, try using an over-the-counter disclosing solution. This harmless product will temporarily stain any plaque or debris that got left behind after brushing, so they can immediately see where they missed, and how to improve their hygiene technique — which will lead to better health.
Have regular dental exams & cleanings — When kids see you're enthusiastic about going to the dental office, it helps them feel the same way… and afterward, you can point out how great it feels to have a clean, sparkling smile.
One of the keys to a healthy mouth is daily oral hygiene. These tasks have one objective: remove plaque, a thin film of bacteria and leftover food particles, from tooth surfaces. Plaque fosters bacterial growth that can cause diseases like tooth decay or periodontal (gum) disease.
Brushing does an effective job removing plaque from the broad surfaces of teeth. But because plaque can also grow between teeth where your brush can’t reach, you also need to floss.
Unfortunately, flossing is a lot of people’s least favorite hygiene task. It can be time-consuming and requires a little more dexterity than brushing. As a result, it’s common for people to brush but not floss — and potentially miss plaque that could trigger dental disease.
There is an easier alternative to traditional string flossing: an oral irrigator. These countertop appliances deliver a stream of pulsating water at high pressure through a handheld device that looks similar to a power toothbrush. The user directs the water stream through the nozzle tip (which comes in various sizes) between the teeth. The water vibrates plaque loose and then rinses it away.
Besides people with limited dexterity, water flossers are also ideal for individuals wearing braces or other orthodontic hardware. Because of the metal hardware on and around teeth, flossing can be an arduous task. An oral irrigator makes it easier to floss and reduce plaque buildup, a perennial problem for orthodontic patients. In fact, one study of orthodontic patients found that using an irrigator with a tip especially designed for braces removed five times as much plaque as patients using only a manual toothbrush.
Of course, anyone can use an oral irrigator as an alternative to traditional flossing. Your dentist and staff can advise you on what to look for in equipment and provide instruction on how to use it. If traditional flossing isn’t your thing, consider an oral irrigator to get rid of plaque and keep your teeth and gums healthy and attractive.
