GumDiseaseisStillaThreattoYourDentalImplants

You’ve invested quite a bit in your new dental implants. And it truly is an investment: because of implants’ potential longevity, their long-term costs could actually be lower than other restorations whose upfront costs might be less.

But to better ensure their longevity, you’ll need to keep your implants and the natural tissues supporting them clean of bacterial plaque, a sticky biofilm that can cause periodontal (gum) disease. Although the implant itself is unaffected by disease, the natural tissues around it can be.  An infection could ultimately weaken the bone supporting the implant and lead to its failure.

Such an infection involving implants could advance rapidly because they don’t have the natural defenses of the original teeth. Our natural teeth are connected to the jaw through the periodontal ligament, a collagen network that attaches to both the teeth and the bone through tiny tissue fibers. This connection also provides access to antibodies produced by the body to fight infection.

By contrast, we place implants directly into the jawbone. While this creates a very secure attachment, the implant won’t have the same connection as teeth with the body’s immune system. That means any infection that develops in surrounding tissues can spread much more rapidly—and so must be dealt with promptly.

Treating this particular form of gum disease (known as peri-implantitis) is similar to infections with natural teeth and gums, with one important difference involving the tools we use to remove plaque from them. While natural teeth can handle metal scalers and curettes, these can create microscopic scratches in the porcelain and metal surfaces of an implant and create havens for further bacterial growth. Instead, we use instruments made of plastic or resin that won’t scratch, as well as ultrasonic equipment to vibrate plaque loose.

To avoid an infection, it’s important that you brush your implants and surrounding tissues just like you would your natural teeth (be sure you use a soft-bristled brush). And keep up regular dental visits for thorough cleanings and checkups to stay ahead of any developing gum infection. Maintaining your dentures will help ensure they continue to brighten your smile for a long time.

LoosePermanentTeethisaProblem-takeActionNow

If you've noticed one of your teeth feeling loose, you're right to believe it's not a good thing. Loose permanent teeth are a sign of an underlying problem.

Periodontal (gum) disease is usually the culprit. Caused by bacterial plaque, a thin film of food particles, gum disease causes the tissues that support teeth to weaken and detach. While a tooth can become loose from too much biting force (primary occlusal trauma), it's more likely bone loss from gum disease has caused so much damage that even the forces from normal biting can trigger looseness.

A loose tooth must be treated or you may lose it altogether. If it's from gum disease, your treatment will have two phases.

In the first phase we need to stop the gum infection by removing plaque and calculus (hardened plaque deposits). Hand instruments known as scalers or ultrasonic equipment are usually sufficient for removing plaque and calculus around or just below the gum line. If the plaque extends deeper near or around the roots, we may need to consider surgical techniques to access these deeper deposits.

Once the infection is under control and the tissues have healed, we can then undertake the second phase: reducing biting forces by breaking clenching and grinding habits, doing a bite adjustment for advanced problems and securing loose teeth with splinting.

Although there are different types of splinting — both temporary and permanent — they all link loose teeth to adjacent secure teeth much like pickets in a fence. One way is to bond dental material to the outer enamel of all the teeth involved; a more permanent technique is to cut a small channel extending across all the teeth and bond a rigid metal splint within it.

To reduce biting forces on loose teeth, we might recommend wearing a bite guard to keep the teeth from generating excessive biting forces with each other. We may also recommend orthodontics to create a better bite or reshape the teeth's biting surfaces by grinding away small selected portions of tooth material so they generate less force.

Using the right combination of methods we can repair loose teeth and make them more secure. But time is of the essence: the sooner we begin treatment for a loose tooth, the better the outcome.

AmericasDentistsGotTalent-forFixingDamagedorMissingTeeth

A recent episode of “America’s Got Talent” featured an engaging 93-year-old strongman called The Mighty Atom Jr. The mature muscleman’s stunt: moving a full-sized car (laden with his octogenarian “kid brother,” his brother’s wife, plus Atom’s “lady friend”) using just his teeth. Grinning for host Howie Mandel, Atom proudly told the TV audience that his teeth were all his own; then he grasped a leather strap in his mouth, and successfully pulled the car from a standstill.

We’re pleased to see that the Atom has kept his natural teeth in good shape: He must have found time for brushing and flossing in between stunts. Needless to say, his “talent” isn’t one we’d recommend trying at home. But aside from pulling vehicles, teeth can also be chipped or fractured by more mundane (yet still risky) activities — playing sports, nibbling on pencils, or biting too hard on ice. What can you do if that happens to your teeth?

Fortunately, we have a number of ways to repair cracked or chipped teeth. One of the easiest and fastest is cosmetic bonding with tooth-colored resins. Bonding can be used to fill in small chips, cracks and discolorations in the teeth. The bonding material is a high-tech mixture of plastic and glass components that’s extremely lifelike, and can last for several years. Plus, it’s a procedure that can be done right in the office, with minimal preparation or discomfort. However, it may not be suitable for larger chips, and it isn’t the longest-lasting type of restoration.

When more of the tooth structure is missing, a crown (or cap) might be needed to restore the tooth’s appearance and function. This involves creating a replacement for the entire visible part of the tooth in a dental lab — or in some cases, right in the office. It typically involves making a model of the damaged tooth and its neighbors, then fabricating a replica, which will fit perfectly into the bite. Finally, the replacement crown is permanently cemented to the damaged tooth. A crown replacement can last for many years if the tooth’s roots are in good shape. But what if the roots have been dislodged?

In some cases it’s possible to re-implant a tooth that has been knocked out — especially if it has been carefully preserved, and receives immediate professional attention. But if a tooth can’t be saved (due to a deeply fractured root, for example) a dental implant offers today’s best option for tooth replacement. This procedure has a success rate of over 95 percent, and gives you a natural looking replacement tooth that can last for the rest of your life.

So what have we learned? If you take care of your teeth, like strongman Atom, they can last a long time — but if you need to move your car, go get the keys.
