SixWaysSalivaHelpsYourMouthandBodyStayHealthy

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.

ManageYourOsteoporosisMedicationtoAvoidJawboneProblems

Around 20 million people—mostly women after menopause—take medication to slow the progress of osteoporosis, a debilitating disease that weakens bones. But although effective, some osteoporosis drugs could pose dental issues related to the jawbones.

Osteoporosis causes the natural spaces that lie between the mineral content of bone to grow larger over time. This makes the bone weaker and unable to withstand forces it once could, which significantly increases the risk of fracture. A number of drugs have been developed over time that stop or slow this disease process.

Two of the most prominent osteoporosis drugs are alendronate, known also by its trade name Fosamax™, and denosumab or Prolia™. While originating from different drug families, alendronate and denosumab work in a similar way by destroying specialized bone cells called osteoclasts that break down worn out bone and help dissolve it. By reducing the number of these cells, more of the older bone that would have been phased out lasts longer.

In actuality this only offers a short-term benefit in controlling osteoporosis. The older bone isn’t renewed but only preserved, and will eventually become fragile and more prone to fracture. After several years the tide turns negatively for the bone’s overall health. It’s also possible, although rare, that the bone simply dies in a condition called osteonecrosis.

The jawbones are especially susceptible to osteonecrosis. Forces generated by chewing normally help stimulate jawbone growth, but the medications in question can inhibit that stimulus. As a result the jawbone can diminish and weaken, making eventual tooth loss a real possibility.

Osteonecrosis is most often triggered by trauma or invasive dental procedures like tooth extractions or oral surgery. For this reason if you’re taking either alendronate and denosumab and are about to undergo a dental procedure other than routine cleaning, filling or crown-work, you should speak to your physician about suspending your medication temporarily. Dentists often recommend a suspension of three to nine months before the procedure and three months afterward.

Some research indicates this won’t worsen your osteoporosis symptoms, especially if you substitute another treatment or fortify your skeletal system with calcium and vitamin D supplements. But taking this temporary measure could help protect your teeth in the long run.

MinimallyInvasiveDentistryANewApproachtoPreventingandTreatingDecay

Since the late 19th Century, dentists have used established protocols to successfully prevent and treat tooth decay. But there've been changes to this approach the last few years to improve its effectiveness, changes we now refer to as Minimally Invasive Dentistry or MID.

The older approach for treating dental caries (tooth decay) follows the protocols established by Dr. G.V. Black, considered the father of modern dentistry. Black advocated removing not only decayed structure but also some of the healthier but vulnerable portions of a tooth, to avoid further decay and make the tooth easier to clean. This resulted in larger fillings, although they've become smaller as dental techniques have advanced.

MID, on the other hand, aims to remove as little tooth structure as possible while still effectively treating and preventing future decay. To achieve that goal we begin first with a complete assessment of a patient's individual decay risk, known as Caries Management By Risk Assessment (CAMBRA).

With CAMBRA, we're looking at other factors besides individual tooth health: a patient's hygiene, lifestyle and dietary habits; the types and amount of bacteria present; and the quality of saliva flow, needed to neutralize mouth acid. With these the results we develop a customized prevention and treatment strategy.

MID also focuses on detecting dental caries as early as possible. Besides traditional x-rays, we're beginning to use other methods like dental microscopes, laser fluorescence, infrared photography or optical scanning. Early detection leads to early intervention, and with techniques that are much less invasive than the traditional approach.

The new approach also changes how we repair decayed teeth. We're increasingly using air abrasion, a technology that uses fine particles in a pressurized air stream to remove softer decayed tooth material and less healthy structure than the traditional dental drill. We're also using composite resin and other advanced materials for filings: these tooth-colored materials are stronger than previous versions and are quickly taking the place of metal amalgam, requiring less structural removal to accommodate them.

MID's core principles are early disease detection, proactive prevention and treatment with less structural removal. With this enhanced approach to effective dentistry, we're keeping your teeth healthy with minimal discomfort, lower costs and less long-term impact.

FanofSuperheroFilmBlackPantherBreaksSteelWirewithHerMouth

Some moviegoers have been known to crunch popcorn, bite their fingers or grab their neighbor’s hands during the intense scenes of a thriller. But for one fan, the on-screen action in the new superhero film Black Panther led to a different reaction.

Sophia Robb, an 18-year-old Californian, had to make an emergency visit to the orthodontic office because she snapped the steel wire on her retainer while watching a battle scene featuring her Hollywood crush, Michael B. Jordan. Her jaw-clenching mishap went viral and even prompted an unexpected reply from the actor himself!

Meanwhile, Sophia got her retainer fixed pronto—which was exactly the right thing to do. The retention phase is a very important part of orthodontic treatment: If you don’t wear a retainer, the beautiful new smile you’re enjoying could become crooked again. That’s because if the teeth are not held in their new positions, they will naturally begin to drift back into their former locations—and you may have to start treatment all over again…

While it’s much more common to lose a removable retainer than to damage one, it is possible for even sturdy retainers to wear out or break. This includes traditional plastic-and-wire types (also called Hawley retainers), clear plastic retainers that are molded to fit your teeth (sometimes called Essix retainers), and bonded retainers: the kind that consists of a wire that’s permanently attached to the back side of your teeth. So whichever kind you use, do what Sophia did if you feel that anything is amiss—have it looked at right away!

When Black Panther co-star Michael B. Jordan heard about the retainer mishap, he sent a message to the teen: “Since I feel partly responsible for breaking your retainers let me know if I can replace them.” His young fan was grateful for the offer—but even more thrilled to have a celebrity twitter follower.

If you have questions about orthodontic retainers, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “The Importance of Orthodontic Retainers” and “Bonded Retainers.”

GettheFactsAboutPopularArtificialSweeteners

Barley malt, corn syrup, maltodextrin — these and over fifty other label ingredients are all names for refined sugar. Under its various aliases, this sweet carbohydrate is tucked away in three-quarters of packaged foods in the U.S.

Although in recent years the general health effects from too much sugar have gained the spotlight, its effect on dental health has been known for decades. Accumulated sugar in the mouth is a prime food source for bacteria that cause tooth decay and gum disease.

For both general and oral health, people have been looking to artificial alternatives to satisfy their sweet tooth. But do they have their own issues that can impact overall health? Here is an overview of some of the more popular brands of artificial sweeteners and their effect on health.

Saccharin — One of the most widely used artificial sweeteners, saccharin is often used under the names Sweet’N Low or Sugar Twin in low-calorie foods because it contains no calories. According to the Food and Drug Administration (FDA) there are no associated health risks with consuming saccharin in recommended servings.

Aspartame — used commonly in beverages as Equal or NutraSweet, aspartame is unsuitable for cooking because its chemical structure breaks down under high heat. Although generally safe for consumption, it can affect people with a rare condition known as phenylketonuria that can’t adequately break down its chemicals.

Sucralose — marketed as Splenda, this sweetener is made by chemically altering refined table sugar so the body can’t process it. This may be one reason it has the most recognized natural flavor profile among consumers and is a market leader. It’s stable at high temperatures, so it’s often used in cooked or baked goods.

Stevia/Erythritol — this combination of an extract from the extremely sweet herb stevia and the sugar alcohol erythritol is marketed as Truvia. Unlike other calorie-free artificial sweeteners, this and other alcohol-based sweeteners have a low calorie level due to sugar alcohol’s characteristic of slow and incomplete absorption during digestion.

Xylitol — although all the previously mentioned sweeteners won’t promote bacterial growth like refined sugar, the sugar alcohol xylitol — often added to chewing gum and mints — has an added benefit: it may actually reduce levels of bacteria most likely to cause decay.
