OvercomingBoneLossPreventingYouFromGettinganImplant

Introduced to the United States in the 1980s, dental implants have quickly become the go-to restoration for tooth replacement. And for good reason: they're not only incredibly life-like, they're highly durable with a 95% success rate.

But as desirable as they are, you may face a major obstacle getting one because of the condition of the bone at your implant site. To position the implant for best appearance and long-term durability, we must have at least 4-5 mm of bone available along the horizontal dimension. Unfortunately, that's not always the case with tooth loss.

This is because bone, like other living tissue, has a growth cycle: Older cells die and dissolve (resorb) and newer cells develop in their place. The forces transmitted to the jaw from the action of chewing help stimulate this resorption and replacement cycle and keep it on track. When a tooth is lost, however, so is this stimulus.

This may result in a slowdown in cell replacement, causing the eventual loss of bone. And it doesn't take long for it to occur after tooth loss—you could lose a quarter of bone width in just the first year, leaving you without enough bone to support an implant. In some cases, it may be necessary to choose another kind of restoration other than implants.

But inadequate bone isn't an automatic disqualifier for implants. It's often possible to regenerate lost bone through a procedure known as bone augmentation, in which we insert a bone graft at the missing tooth site. The graft serves as a scaffold for new bone cells to grow upon, which over time may regenerate enough bone to support an implant.

Even if you've had a missing tooth for some time, implementing bone augmentation could reverse any loss you may have experienced. In fact, it's a common practice among dentists to place a bone graft immediately after a tooth extraction to minimize bone loss, especially if there will be a time lag between extraction and implant surgery.

Bone augmentation could add extra time to the implant process. But if successful, it will make it possible for you to enjoy this popular dental restoration.

HowAFVsAlfonsoRibeiroSavedHisTooth

Remembered fondly by fans as the wacky but loveable Carlton on The Fresh Prince of Bel-Air, Alfonso Ribeiro is currently in his fifth year hosting America's Funniest Videos. It's the perfect gig for the 48-year-old actor, who loves to laugh and make others laugh as well. This is quite the opposite experience from one he had a few years ago that he remembers all too well: a severely decayed tooth.

After seeing his dentist for an intense toothache, Ribeiro learned he had advanced tooth decay and would need root canal treatment. Ribeiro wasn't thrilled by the news. Like many of us, he thought the procedure would be unpleasant. But he found afterward that not only was the root canal painless, his toothache had vanished.

More importantly, the root canal treatment saved his tooth, as it has for millions of others over the last century. If you're facing a situation similar to Alfonso Ribeiro's, here's a quick look at the procedure that could rescue your endangered tooth.

Getting ready. In preparation for root canal therapy, the tooth and surrounding gums are numbed, often first with a swab of local anesthesia to deaden the surface area in preparation for the injection of the main anesthesia below the surface. A dental dam is then placed to isolate the infected tooth from its neighbors to prevent cross-contamination.

Accessing the interior. To get to the infection, a small access hole is drilled. The location depends on the tooth: in larger back teeth, a hole is drilled through the biting surface, and in front teeth, a hole is drilled on the backside. This access allows us to insert special tools to accomplish the next steps in the procedure.

Cleaning, shaping and filling. Small tools are used to remove the diseased tissue from the interior tooth pulp and root canals. Then the empty spaces are disinfected. This, in effect, stops the infection. Next, the root canals inside the tooth are shaped to allow them to better accept a special filling called gutta percha. The access hole is then sealed to further protect the tooth from future infection, and a temporary crown is placed.

A new crown to boot. Within a couple weeks, we'll cap the tooth with a long-lasting lifelike crown (or a filling on certain teeth). This adds further protection for the tooth against infection, helps strengthen the tooth's structure, and restores the tooth's appearance.

Without this procedure, the chances of a tooth surviving this level of advanced decay are very slim. But undergoing a root canal, as Alfonso Ribeiro did, can give your tooth a real fighting chance.

SeeYourDentistASAPtoSaveYourLooseTooth

A loose adult tooth isn't normal. It could be loose because it's been subjected to high biting forces like those that occur with a tooth grinding habit. Or, it could be the result of periodontal (gum) disease or some other infection that has weakened some of the tooth's supporting gums and bone. Whatever the underlying cause, we'll need to act quickly to save your tooth.

Our first step is to find out this exact cause—that will determine what treatment course we need to follow. For a tooth grinding habit, for example, you might need to wear an occlusal guard or have your bite (teeth) adjusted. With gum disease, we'll focus on removing dental plaque, the thin film of bacteria and tartar (calculus) fueling the infection. This stops the infection and minimizes any further damage.

While we're treating the cause, we may also need to secure the loose tooth with splinting. This is a group of techniques used to join loose teeth to more stable neighboring teeth, similar to connecting pickets in a fence. Splinting can be either temporary or permanent.

Temporary splinting usually involves composite materials with or without strips of metal to bond the loose tooth to its neighbors as the periodontal structures heal. Once the tooth's natural attachments return to health, we may then remove the splint.

There are a couple of basic techniques we can use for temporary splinting. One way is to bond the splint material to the enamel across the loose tooth and the teeth chosen to support it (extra-coronal splinting). We can also cut a small channel across all the affected teeth and then insert metal ligatures and bond the splint material within the channel (intra-coronal).

If we're not confident the loose tooth will regain its natural gum attachment, we would then consider a permanent splint. The most prominent method involves crowning the loose tooth and supporting teeth with porcelain crowns. We then fuse the crowns together to create the needed stability for the loose teeth.

Whatever splinting method we use, it's important to always address the root cause for a tooth's looseness. That's why splinting usually accompanies other treatments. Splinting loose teeth will help ensure your overall treatment is successful.

IncreaseBoneMassforDentalImplantsthroughGrafting

Losing a tooth from disease or accident can be traumatic. The good news, though, is that it can be replaced with a life-like replica that restores your smile. One of the most popular and durable solutions is a dental implant, which replaces not only the root of the tooth but the crown as well.

But there's a possible wrinkle with implants — for accurate placement there must be a sufficient amount of bone around it. This could be a problem if you've been missing the tooth for sometime: without the stimulus provided by a tooth as you chew, older bone cells aren't replaced at an adequate rate. The bone volume gradually diminishes, as up to 25% of its normal width can be lost during the first year after tooth loss. A traumatic injury can damage underlying bone to an even greater extent.

There is a possible solution, but it will require the services of other specialists, particularly a periodontist trained in gum and bone structure. The first step is a complete examination of the mouth to gauge the true extent of any bone loss. While x-rays play a crucial role, a CT scan in particular provides a three-dimensional view of the jaw and more detail on any bone loss.

With a more accurate bone loss picture, we can then set about actually creating new bone through grafting procedures. One such technique is called a ridge augmentation: after opening the gum tissues, we place the bone graft within a barrier membrane to protect it. Over time the bone will grow replacing both the grafting material and membrane structure.

Once we have enough regenerated bone, we can then perform dental implant surgery. There are two options: a “one-stage” procedure in which a temporary crown is placed on the implant immediately after surgery; or a “two-stage” in which we place the gum tissue over the implant to protect it as it heals and bone grows and attaches to it. In cases of pre-surgical bone grafting, it's usually best to go with the two-stage procedure for maximum protection while the bone strengthens around it.

Necessary preparation of the bone for a future dental implant takes time. But the extra effort will pay off with a new smile you'll be proud to display.

HughJackmanIsAllSmilesforHisNewBroadway-InspiredShow

To anyone immersed in the “X-Men Universe” Hugh Jackman will always be Wolverine, a role he played in seven movies. But there’s more to this Australian actor than mutant bone claws and mutton chops that would make Elvis envious. Jackman has also starred in over 20 non-superhero films, including Les Misérables, for which he won a Golden Globe. He is also a Tony award-winning Broadway performer—with a winning smile.

With his famed character Logan/Wolverine fading in the rearview mirror, Jackman has returned to his musical roots. He will play Harold Hill in the Broadway revival of The Music Man, set to open in Fall 2020. And since May 2019 he’s been on world tour with Hugh Jackman: The Man. The Music. The Show., featuring Jackman and a supporting cast performing songs from favorite shows and films, including Les Misérables and the 2017 hit The Greatest Showman.

The Show, with 90 planned stops throughout Europe, North America and Oceania, is a decidedly different “universe” from the X-Men. As Wolverine, Jackman could get away with a scruffier look. But performing as Jean Valjean or the bigger-than-life P.T. Barnum, he has to bring a vastly different look to the role, which brings us to Jackman’s teeth…

Once upon a time, Jackman’s teeth were an unflattering gray—definitely not a good look for stage or film. So with the help of his dentist, Jackman set about upgrading his smile with teeth whitening. Teeth whitening is a great way to take a dull, stained smile and turn up the volume on its brightness—and attractiveness—a notch or two. A dentist applies a bleaching solution that stays in contact with the teeth for a few minutes. The process is often aided by special lighting.

A professional application is especially desirable if, like Jackman, you want “Goldilocks” brightness: not too little, not too much, but just right for you. Dentists can precisely control the tint level to get a brighter but more naturally looking white. Of course, you can also get a dazzling “Hollywood” smile if you so desire.

And although the effect of teeth whitening isn’t permanent, a dental application can last a while, depending on how well you manage foods and beverages that stain teeth. With a touchup now and then, you may be able to keep your brighter smile for years before undergoing the full procedure again.

One important note, though: This technique only works with outer enamel staining. If the discoloration originates from within the tooth, the bleaching agent will have to be placed internally, requiring access to the inside of the tooth. An alternative would be porcelain veneers to mask the discoloration, an option that also works when there is ultra-heavy enamel staining.

If you’re tired of your dull smile, talk with us about putting some pizzazz back into it. Teeth whitening could be your way to get a smile worthy of Broadway.
