BruinsZdenoCharaBreaksHisJawDuring2019StanleyCup

Boston Bruins defenseman Zdeno Chara had a rough Stanley Cup final against the St. Louis Blues this past June. Not only did the Bruins ultimately lose the championship, but Chara took a deflected puck shot to the face in Game Four that broke his jaw.

With the NHL season now over, the 42-year-old Bruins captain continues to mend from his injury that required extensive treatment. His experience highlights how jaw fractures and related dental damage are an unfortunate hazard in hockey—not only for pros like Chara, but also for an estimated half million U.S. amateurs, many in youth leagues.

Ice hockey isn't the only sport with this injury potential: Basketball, football (now gearing up with summer training) and even baseball players are also at risk. That's why appropriate protective gear like helmets and face shields are key to preventing injury.

For any contact sport, that protection should also include a mouthguard to absorb hard contact forces that could damage the mouth, teeth and gums. The best guards (and the most comfortable fit) are custom-made by a dentist based on impressions made of the individual's mouth.

But even with adequate protection, an injury can still happen. Here's what you should do if your child has an injury to their jaw, mouth or teeth.

Recognize signs of a broken jaw. A broken jaw can result in severe pain, swelling, difficulty speaking, numbness in the chin or lower lip or the teeth not seeming to fit together properly. You may also notice bleeding in the mouth, as well as bruising under the tongue or a cut in the ear canal resulting from jawbone movement during the fracture. Get immediate medical attention if you notice any of these signs.

Take quick action for a knocked-out tooth. A tooth knocked completely out of its socket is a severe dental injury. But you may be able to ultimately save the tooth by promptly taking the following steps: (1) find the tooth and pick it up without touching the root end, (2) rinse it off, (3) place it back in its socket with firm pressure, and (4) see a dentist as soon as possible.

Seek dental care. Besides the injuries already mentioned, you should also see a dentist for any moderate to severe trauma to the mouth, teeth and gums. Leading the list: any injury that results in tooth chipping, looseness or movement out of alignment.

Even a top athlete like Zdeno Chara isn't immune to injury. Take steps then to protect your amateur athlete from a dental or facial injury.

HeresHowWeCanJazzupYourHolidaySmileThisSeason

The holidays have officially begun! Between Thanksgiving and New Year’s Eve, it’s fairly certain you’re going to be spending time with lots of folks. From family gatherings to neighborhood open houses to the office holiday party, you’ll find yourself rubbing elbows with all the in-laws and out-laws in your social orbit. And because it’s the season of cheer, you’ll probably smile—a lot.

So, before the festivities go full tilt, take a little time to freshen up that wonderful smile of yours. Here are a few suggestions for having a smile this holiday season that you’re confident to put on display.

Dental cleanings. While professional dental cleanings primarily remove any lingering disease-causing plaque and tartar, they can have the secondary benefit of improving your smile’s appearance. So, if it’s close to time for your regular dental visit or you would simply like to give your teeth a quick polish, schedule a cleaning appointment for a little extra holiday sparkle.

Teeth whitening. You can gain a noticeable increase in smile brightness with a professional whitening application. With our advanced bleaching solutions and techniques, we can precisely control the level of brightness you desire, from a more subdued natural white to a dazzling “Hollywood” shine. And with care, the effect could last for several months or even years with an occasional touch-up.

Bonding. A chipped tooth can stand out from your smile like a smudge on a masterpiece painting. In many cases, though, we can repair minor chips and other defects by bonding composite resin to the tooth in a single visit. The process is simple: We color-match the resin to the tooth, then apply, shape and cure it. Your tooth will look good as new.

Porcelain veneers. For a more durable and comprehensive solution, consider veneers for dental flaws you do not wish to live with. These thin wafers of porcelain are permanently bonded to the front of teeth to mask chips, heavy staining or slight misalignments. And they are quite affordable compared to more extensive cosmetic restorations.

All of these cosmetic options can fit into most people’s budgets and don’t take a lot of time in the dentist’s chair. Veneers are the one slight exception: These require more than one visit to the dental office because they are custom-made for you in a dental lab. Also note that veneers often require the permanent removal of tooth enamel, so the tooth will require a veneer or other restorative covering from then on.

All in all, though, it doesn’t take much to put some much-needed zing back into your smile. In most cases, it only takes one visit—just in time to brighten up your holiday season.

DontWorryAboutDentalAmalgamItsSafeforTreatingCavities

Dental amalgam—also known as “silver fillings”—has been used for nearly a hundred years to treat cavities. There are several reasons why this mixture of metals has been the go-to material among dentists: Malleable when first applied, dental amalgam sets up into a durable dental filling that can take years of biting forces. What’s more, it’s stable and compatible with living tissue.

But there’s been growing concern in recent years about the safety of dental amalgam, with even some wondering if they should have existing fillings replaced. The reason: liquid mercury.

Mercury makes up a good portion of dental amalgam’s base mixture, to which other metals like silver, tin or copper are added to it in powder form. This forms a putty that can be easily worked into a prepared cavity. And despite the heightened awareness of the metal’s toxicity to humans, it’s still used in dental amalgam.

The reason why is that there are various forms of mercury and not all are toxic. The form making headlines is known as methylmercury, a compound created when mercury from the environment fuses with organic molecules. The compound builds up in the living tissues of animals, particularly large ocean fish, which have accumulated high concentrations passed up through their food chain.

That’s not what’s used in dental amalgam. Dentists instead use a non-toxic, elemental form of mercury that when set up becomes locked within the amalgam and cannot leach out. Based on various studies, treating cavities with it poses no health risks to humans.

This also means there’s no medical reason for having an existing silver fillings removed. Doing so, though, could cause more harm than good because it could further weaken the remaining tooth structure.

The most viable reason for not getting a dental amalgam filling is cosmetic: The metallic appearance of amalgam could detract from your smile. There are newer, more life-like filling options available. Your dentist, though, may still recommend dental amalgam for its strength and compatibility, especially for back teeth. It’s entirely safe to accept this recommendation.
