JimmyFallonCanrsquotCatchaBreak-ExceptinHisTooth

Want to know the exact wrong way to pry open a stubborn lid? Just ask Jimmy Fallon, host of NBC-TV’s popular “Tonight Show.” When the 40-year-old funnyman had trouble opening a tube of scar tissue repair gel with his hands, he decided to try using his teeth.

What happened next wasn’t funny: Attempting to remove the cap, Fallon chipped his front tooth, adding another medical problem to the serious finger injury he suffered a few weeks before (the same wound he was trying to take care of with the gel). If there’s a moral to this story, it might be this: Use the right tool for the job… and that tool isn’t your teeth!

Yet Fallon is hardly alone in his dilemma. According to the American Association of Endodontists, chipped teeth account for the majority of dental injuries. Fortunately, modern dentistry offers a number of great ways to restore damaged teeth.

If the chip is relatively small, it’s often possible to fix it with cosmetic bonding. In this procedure, tough, natural-looking resin is used to fill in the part of the tooth that has been lost. Built up layer by layer, the composite resin is cured with a special light until it’s hard, shiny… and difficult to tell from your natural teeth. Best of all, cosmetic bonding can often be done in one office visit, with little or no discomfort. It can last for up to ten years, so it’s great for kids who may be getting more permanent repairs later.

For larger chips or cracks, veneers or crowns may be suggested. Veneers are wafer-thin porcelain coverings that go over the entire front surface of one or more teeth. They can be used to repair minor to moderate defects, such as chips, discolorations, or spacing irregularities. They can also give you the “Hollywood white” smile you’ve seen on many celebrities.

Veneers are generally custom-made in a lab, and require more than one office visit. Because a small amount of tooth structure must be removed in order to put them in place, veneers are considered an irreversible treatment. But durable and long-lasting veneers are the restorations of choice for many people.

Crowns (also called caps) are used when even more of the tooth structure is missing. They can replace the entire visible part of the tooth, as long as the tooth’s roots remain viable. Crowns, like veneers, are custom-fabricated to match your teeth in size, shape and color; they are generally made in a dental lab and require more than one office visit. However, teeth restored with crowns function well, look natural, and can last for many years.

So what happened to Jimmy Fallon? We aren’t sure which restoration he received… but we do know that he was back on TV the same night, flashing a big smile.

KeepanEyeontheJawBoneAfteraTeenagersToothLoss

Accidents happen, especially to teenagers involved with sports or similar activities. In an instant they can lose one or more teeth and permanently alter their smile.

Fortunately we can restore a teenager’s lost teeth, but often not immediately as a permanent restoration with a dental implant requires maturity of their jaw structure. Our focus then turns to the age of the patient and the condition of the underlying bone. A future dental implant, your best choice for tooth replacement, depends on bone for support, but also the age of the patient as it relates to jaw development.

There are a couple of ways an accidental tooth loss can harm supporting bone: first and foremost, the impact of the accident itself can damage the bony socket. To find out for sure we may need to perform a cone beam scan, a type of x-ray that allows us to view the area three-dimensionally. If we do find damage, we can attempt to repair the socket through bone grafting.

Bone can also suffer from the long-term absence of a tooth. Bone has a growth cycle in which older cells dissolve and new ones form to take their place. The force generated by teeth when we eat or chew helps stimulate this growth. Without stimulation, as with a missing tooth, the bone may not grow at a healthy rate. In time, it could lose some of its volume and density and not be able to support an implant.

Installing an implant right after tooth loss could help avoid this situation. Bone has a natural affinity with the titanium post imbedded in the jaw and will naturally grow and adhere to it. But we can’t place an implant with a teenager. This is because the jaw is still developing so an implant would gradually become misaligned as the jaw grows. It’s best to install an implant later after full jaw development in early adulthood.

Today, we can place a bone graft in the empty socket right after tooth loss. The graft serves as a scaffold for bone cells to grow on and will help keep the bone volume at a healthy level until we can install an implant.

Timing is everything in restoring a teenager’s accidental tooth loss. But with coordination and care for the supporting bone, a teenager can eventually enter their adult years with their smile intact.

DentalCrownsfortheKingofMagic

You might think David Copperfield leads a charmed life:  He can escape from ropes, chains, and prison cells, make a Learjet or a railroad car disappear, and even appear to fly above the stage. But the illustrious illusionist will be the first to admit that making all that magic takes a lot of hard work. And he recently told Dear Doctor magazine that his brilliant smile has benefitted from plenty of behind-the-scenes dental work as well.

“When I was a kid, I had every kind of [treatment]. I had braces, I had headgear, I had rubber bands, and a retainer afterward,” Copperfield said. And then, just when his orthodontic treatment was finally complete, disaster struck. “I was at a mall, running down this concrete alleyway, and there was a little ledge… and I went BOOM!”

Copperfield’s two front teeth were badly injured by the impact. “My front teeth became nice little points,” he said. Yet, although they had lost a great deal of their structure, his dentist was able to restore those damaged teeth in a very natural-looking way. What kind of “magic” did the dentist use?

In Copperfield’s case, the teeth were repaired using crown restorations. Crowns (also called caps) are suitable when a tooth has lost part of its visible structure, but still has healthy roots beneath the gum line. To perform a crown restoration, the first step is to make a precise model of your teeth, often called an impression. This allows a replacement for the visible part of the tooth to be fabricated, and ensures it will fit precisely into your smile. In its exact shape and shade, a well-made crown matches your natural teeth so well that it’s virtually impossible to tell them apart. Subsequently, the crown restoration is permanently attached to the damaged tooth.

There’s a blend of technology and art in making high quality crowns — just as there is in some stage-crafted illusions. But the difference is that the replacement tooth is not just an illusion: It looks, functions and “feels” like your natural teeth… and with proper care it can last for many years to come.  Besides crowns, there are several other types of tooth restorations that are suitable in different situations. We can recommend the right kind of “magic” for you.

BeSuretoHaveaDentalExamBeforeWhiteningYourTeeth

You’ve been embarrassed for a while now by your yellowed, dull teeth. You’re ready for a change.

There’s a simple and cost-effective way to make that change: you can temporarily brighten your smile with teeth whitening, possibly at home. But before you try it, you should first have a dental examination to find out if whitening is the right choice for you.

First off, healthy teeth with outer enamel staining are the best candidates for whitening. Teeth and gums with tooth decay or periodontal (gum) disease should be treated first before undergoing whitening. A dental exam will uncover any health issues you may have with your mouth.

In the same vein, you’ll want to consider whitening carefully if you have dental work like veneers, crowns or implants. Unlike natural teeth, these non-biological materials won’t be affected by the bleaching agent. We can discuss any potential for color mismatch between your whitened natural teeth and your dental work during your examination.

A dental exam can also uncover one other crucial fact — what kind of tooth staining you have. There are two basic types: extrinsic, staining on the outside enamel as we’ve mentioned earlier; and intrinsic, staining that originates from inside a tooth. The whitening kits you purchase from a store and even some of the whitening techniques we use in the office only diminish extrinsic, not intrinsic staining. To address an intrinsically-stained tooth requires a much more involved, invasive clinical technique only performed by dental professionals.

Finally, a dental examination is a good discussion forum for helping you decide between a home kit and a clinical procedure. While DIY kits are effective for the most part, you won’t be able to precisely control the degree of brightness like we can. This could be important if you want a specific shade of whiteness, from a more subtle and natural shade to dazzling “Hollywood” bright. Shade control could also help minimize color mismatch with dental work.

In the end, we want to help you make the best choice for teeth whitening. Even if you decide to pursue whitening at home, we can offer you valuable advice on what to look for when you buy a kit and how to use it. That alone could help ensure you get the new, bright smile you desire!

If we've told you that you require dental fillings find out why composite fillings may be the way to go.fillings

Finding out you have a cavity is certainly never fun, but our Pittsburgh, PA, cosmetic dentist, Dr. Gary Machiko, makes the process as easy as possible so that you don’t have to fret. Getting a tooth filled won’t hurt a bit and you’ll be happy to hear that we can even restore the tooth without having to place unsightly metal fillings.

What are composite fillings?

When some people smile you may notice specks of metal in some of their teeth. This is because their dentist placed metal amalgam fillings to restore those teeth after a cavity. While this used to be the norm decades ago, dental technology has made it possible to place tooth-colored fillings so that no one will even know that you have fillings.

Composite resin is a great material because it is easy to mold and shape to your tooth. Better yet, our Pittsburgh cosmetic dentist will use a shade guide to determine the perfect color of resin we should use to restore your tooth.

How are composite resin fillings placed?

Immediately after removing the decayed portions of the tooth we will get to work restoring it with a filling. Since this resin is putty-like, we can apply it in thin layers. Each layer, after being shaped, is hardened with a laser. Once the filling is complete we will give it a good polish so that it shines like the rest of your tooth.

What are the benefits of composite fillings?

One of the most obvious benefits is that no one will even know that you have a filling when you smile. You’ll feel confident knowing that no one will be able to tell. There is nothing more important than having a tooth that is fully restored and healthy, and composite fillings can offer that. Apart from the cosmetic advantages, cosmetic fillings can also make a tooth stronger and more resilient.

If you are interested in getting aesthetic dentistry in Pittsburgh, PA, turn to the specialists who will be able to make this happen for you. Call us today to find out more about the many great dental services we can offer you and your smile.
