MargotRobbieKnowsAGreatSmileIsWorthProtecting

On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.

“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”

Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.

Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.

A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.

Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.

So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.

ALowSugarHighFiberDietwillHelpKeepYourTeethandGumsHealthy

If you’re brushing and flossing daily, as well as seeing your dentist at least every six months, you’re doing the top things needed to maintain your dental health. But all your hygiene efforts could be undermined if you’re not eating a dental-friendly diet. Simply put, there are foods that protect and promote dental health and those that increase your risk of dental disease.

Diets in the latter category are typically high in added sugar and low in natural food fiber. The largest sources of these are processed sugars from sugar cane or beets and high fructose corn syrup. With just a little knowledgeable label reading, you can find sugar and its various aliases added to thousands of processed food items including pastries, candies, sodas and energy drinks.

Heavy consumption of processed sugars also contributes to dental disease. Disease-causing bacteria thrive on sugar as a food source, which fuels both their growth and their production of oral acid. Elevated acid levels can dissolve the minerals in tooth enamel faster than saliva can keep up. Softened enamel opens the door to tooth decay, while increased bacterial growth can lead to periodontal (gum) disease.

A diet, however, low in added sugar and high in fiber can have the opposite effect. Although fresh fruits and vegetables contain natural sugars, they also have indigestible parts called fiber that slow the digestion of any sugars and allow the body to more efficiently process them.  With the higher quantity of vitamins and minerals found in unprocessed foods, the overall effect of this diet is a decrease in your risk for dental disease.

Speaking of dental-friendly foods, we should also give honorable mentions to certain dairy items like cheese and milk that stimulate saliva production and are rich in calcium needed for tooth strength. Another beneficial category is both black and green tea, which contain antioxidants to fight disease and fluoride to strengthen enamel.

Adopting a low-sugar/high-fiber diet can have a profound impact on your overall health. Over time, you’ll also reap dental health rewards with stronger teeth and gums and a lower risk of tooth decay and gum disease.

WhySmokingandDentalImplantsDontMix

With a 95-plus percent survival rate after ten years, dental implants are one of the most durable replacement restorations available. Implants can potentially last much longer than less expensive options, which could make them a less costly choice in the long run.

But although a rare occurrence, implants can and do fail—often in the first few months. And tobacco smokers in particular make up a sizeable portion of these failures.

The reasons stem from smoking’s effect on oral health. Inhaled smoke can actually burn the outer skin layers in the mouth and eventually damage the salivary glands, which can decrease saliva production. Among its functions, saliva provides enzymes to fight disease; it also protects tooth enamel from damaging acid attacks. A chronic “dry mouth,” on the other hand, increases the risk of disease.

The chemical nicotine in tobacco also causes problems because it constricts blood vessels in the mouth and skin. The resulting reduced blood flow inhibits the delivery of antibodies to diseased or wounded areas, and so dramatically slows the healing process. As a result, smokers can take longer than non-smokers to recover from diseases like tooth decay or periodontal (gum) disease, or heal after surgery.

Both the higher disease risk and slower healing can impact an implant’s ultimate success. Implant durability depends on the gradual integration between bone and the implant’s titanium metal post that naturally occurs after placement. But this crucial process can be stymied if an infection resistant to healing arises—a primary reason why smokers experience twice the number of implant failures as non-smokers.

So, what should you do if you’re a smoker and wish to consider implants?

First, for both your general and oral health, try to quit smoking before you undergo implant surgery. At the very least, stop smoking a week before implant surgery and for two weeks after to lower your infection risk. And you can further reduce your chances for failure by practicing diligent daily brushing and flossing and seeing your dentist regularly for cleanings and checkups.

It’s possible to have a successful experience with implants even if you do smoke. But kicking the habit will definitely improve your odds.
