WhyKathyBatesChoseThisAlternativetoBracesandsoMightYou

Kathy Bates has been a familiar face to filmgoers since her Oscar-winning performance as Annie Wilkes in Misery. She's best known for playing true-to-life characters like Wilkes or Barbara Jewell in last year's Richard Jewell (for which she earned her fourth Oscar nomination). To keep it real, she typically eschews cosmetic enhancements—with one possible exception: her smile.

Although happy with her teeth in general, Bates noticed they seemed to be “moving around” as she got older. This kind of misalignment is a common consequence of the aging process, a result of the stresses placed on teeth from a lifetime of chewing and biting.

Fortunately, there was an orthodontic solution for Bates, and one compatible with her film career. Instead of traditional braces, Bates chose clear aligners, a newer method for moving teeth first introduced in the late 1990s.

Clear aligners are clear, plastic trays patients wear over their teeth. A custom sequence of these trays is developed for each patient based on their individual bite dimensions and treatment goals. Each tray in the sequence, worn in succession for about two weeks, places pressure on the teeth to move in the prescribed direction.

While clear aligners work according to the same teeth-moving principle as braces, there are differences that make them more appealing to many people. Unlike traditional braces, which are highly noticeable, clear aligners are nearly invisible to others apart from close scrutiny. Patients can also take them out, which is helpful with eating, brushing and flossing (a challenge for wearers of braces) and rare social occasions.

That latter advantage, though, could pose a problem for immature patients. Clear aligner patients must have a suitable level of self-responsibility to avoid the temptation of taking the trays out too often. Families of those who haven't reached this level of maturity may find braces a better option.

Clear aligners also don't address quite the range of bite problems that braces can correct. Some complex bite issues are thus better served by the traditional approach. But that gap is narrowing: Recent advances in clear aligner technology have considerably increased their treatability range.

With that said, clear aligners can be an ideal choice for adults who have a treatable bite problem and who want to avoid the appearance created by braces. And though they tend to be a little more expensive than braces, many busy adults find the benefits of clear aligners to be worth it.

The best way to find out if clear aligners could be a viable option for you is to visit us for an exam and consultation. Like film star Kathy Bates, you may find that this way of straightening your smile is right for you.

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.

WhyandHowtoSaveaDiseasedTooth

Let's say you have a diseased tooth you think might be on its last leg. It might be possible to save it, perhaps with a significant investment of time and money. On the other hand, you could have it replaced with a life-like dental implant.

That seems like a no-brainer, especially since implants are as close as we have to natural teeth. But you might want to take a second look at salvaging your tooth—as wonderful as implants are, they can't beat the real thing.

Our teeth, gums and jaws form an intricate oral system: Each part supports the others for optimum function and health. Rescuing a troubled tooth could be the best way to preserve that function, and replacing it, even with a dental implant, a less satisfying option.

How we save it will depend on what's threatening it, like advanced tooth decay. Caused by bacterial acid that creates a cavity in enamel and underlying dentin, decay can quickly spread into the tooth's pulp and root canals, and eventually threaten the supporting bone.

We may be able to stop decay and save the tooth with a root canal treatment. During this procedure, we remove diseased tissue from the pulp and root canals through a drilled access hole, and then fill the empty spaces. We then seal the access and later crown the tooth to protect it against future infection.

A second common threat is periodontal (gum) disease. Bacteria in dental plaque infect the outer gums and, like tooth decay, the infection quickly spreads deeper into the root and bone. The disease weakens gum attachments to affected teeth, hastening their demise.

To treat gum disease, we manually remove built-up plaque and tartar (hardened plaque). This deprives the infecting bacteria of their primary food source and “starves” the infection. Depending on the disease's advancement, this might take several cleaning sessions and possible gum surgery to access deep pockets of infection around the root.

Because both of these treatment modalities can be quite in-depth, we'll need to assess the survivability of the tooth. The tooth could be too far gone and not worth the effort and expense to save it. If there is a reasonable chance, though, a rescue attempt for your troubled tooth might be the right option.

WecanBuildupLostBoneBeforeYourImplant

The “magic” behind a dental implant’s durability is the special affinity its imbedded titanium post has with bone. Over time bone grows and attaches to the titanium surface to produce a strong and secure hold.

But there’s one important prerequisite for ultimate implant success—there must be an adequate amount of bone available initially to properly position the post during implantation. Otherwise, the implant may not have enough support to position it properly or cover the implant surface completely with bone.

Inadequate bone can be a problem for patients who lost teeth some time before and now desire to an implant restoration. This happens because when teeth are missing, so are the forces they generate during chewing. These forces stimulate new bone growth around the tooth root to replace older, dissolved bone at a healthy rate. If that replacement rate is too slow, the volume and density of bone may gradually diminish.

There is a way, though, to build up the bone for future implantation. Known as bone preservation procedure or a ridge augmentation, it’s a surgical procedure in which the dentist adds bone grafting material to the extraction socket or the bony ridge. The graft serves as a scaffold for new bone cells to grow and multiply. If successful, there will be enough new bone volume after several months of healing to support proper implant placement.

Bone grafting can add more time to the implant process. It may also mean you will not be able to undergo immediate crown placement after implantation (a “tooth in one day” procedure). Instead we would probably suture gum tissue over the implant to protect it and allow for full integration with the bone over a few more months. In the meantime, though, we could fit you with a temporary restoration like a removable partial denture (RPD) or a bonded bridge to improve the appearance of the space while the bone continues to heal.

After several months, your implant will have a better chance of a secure hold and we can then attach a life-like crown. Even if you’ve suffered bone loss, you’ll then have the benefit of not only a durable implant but also a new smile.

AlthoughRareAllergicReactionstotheMetalinImplantsCouldbeaConcern

You’re considering dental implants and you’ve done your homework: you know they’re considered the best tooth replacements available prized for durability and life-likeness. But you do have one concern — you have a metal allergy and you’re not sure how your body will react to the implant’s titanium and other trace metals.

An allergy is the body’s defensive response against any substance (living or non-living) perceived as a threat. Allergic reactions can range from a mild rash to rare instances of death due to multiple organ system shutdowns.

A person can become allergic to anything, including metals. An estimated 17% of women and 3% of men are allergic to nickel, while 1-3% of the general population to cobalt and chromium. While most allergic reactions occur in contact with consumer products (like jewelry) or metal-based manufacturing, some occur with metal medical devices or prosthetics, including certain cardiac stents and hip or knee replacements.

There are also rare cases of swelling or rashes in reaction to metal fillings, commonly known as dental amalgam. A mix of metals — mainly mercury with traces of silver, copper and tin — dental amalgam has been used for decades with the vast majority of patients experiencing no reactions. Further, amalgam has steadily declined in use in recent years as tooth-colored composite resins have become more popular.

Which brings us to dental implants: the vast majority are made of titanium alloy. Titanium is preferred in implants not only because it’s biocompatible (it “gets along” well with the body’s immune system), but also because it’s osteophilic, having an affinity with living bone tissue that encourages bone growth around and attached to the titanium. Both of these qualities make titanium a rare trigger for allergies even for people with a known metal allergy.

Still, implant allergic reactions do occur, although in only 0.6% of all cases, or six out of a thousand patients. The best course, then, is to let us know about any metal allergies you may have (or other systemic conditions, for that matter) during our initial consultation for implants. Along with that and other information, we'll be better able to advise you on whether implants are right for you.
