Implant-SupportedDenturesCouldImproveYourBoneHealth

Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.

Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.

While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.

But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.

Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.

There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.

The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.

While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.

J-LosUnluckyBreakChippingaToothonStage

Whether she’s singing, dancing or acting, Jennifer Lopez is a performer who is known for giving it all she’s got. But during one show, Lopez recently admitted, she gave a bit more then she had planned.

“I chipped my tooth on stage,” she told interviewers from Entertainment Tonight, “and had to finish the show….I went back thinking ‘Can I finish the show like this?’”

With that unlucky break, J-Lo joins a growing list of superstar singers—including Taylor Swift and Michael Buble—who have something in common: All have chipped their teeth on microphones while giving a performance.

But it’s not just celebs who have accidental dental trouble. Chips are among the most common dental injuries—and the front teeth, due to their position, are particularly susceptible. Unfortunately, they are also the most visible. But there are also a number of good ways to repair chipped, cracked or broken teeth short of replacing them.

For minor to moderate chips, cosmetic bonding might be recommended. In this method, special high-tech resins, in shades that match your natural teeth, are applied to the tooth’s surface. Layers of resin, cured with a special light, will often restore the tooth to good appearance. Best of all, the whole process can often be done in just one visit to the dental office, and the results can last for several years.

For a more permanent repair—or if the damage is more extensive—dental veneers may be another option. Veneers are wafer-thin shells that cover the entire front surface of one or more teeth. Strong, durable and natural-looking, they can be used to repair moderate chips, cracks or irregularities. They can also help you get a “red-carpet” smile: brilliant white teeth with perfectly even spacing. That’s why veneers are so popular among Hollywood celebs—even those who haven’t chipped their teeth!

Fortunately, even if the tooth is extensively damaged, it’s usually possible to restore it with a crown (cap), a bridge—or a dental implant, today’s gold standard for whole-tooth replacement. But in many cases, a less complex type of restoration will do the trick.

Which tooth restoration method did J-Lo choose? She didn’t say—but luckily for her adoring fans, after the microphone mishap she went right back up on stage and finished the show.

If you have a chipped tooth but you need to make the show go on, please contact us or schedule an appointment for a consultation. You can also learn more by reading the Dear Doctor magazine articles “Artistic Repair of Chipped Teeth With Composite Resin” and “Porcelain Veneers.”

ALittleOrthodonticMagicCouldHelpanImpactedToothErupt

Bite problems aren't limited to teeth simply out of position. The problem could be some teeth aren't there—visibly, that is. They still exist below the gums and bone, but they've been crowded out and blocked from erupting. We call this condition impaction.

Any tooth can become impacted and affect the bite, but a person's smile suffers more if it involves visible front teeth. This is especially so if the teeth in question are upper canines or "eye teeth"—the smile doesn't look normal without these pointed teeth on either side of the central and lateral incisors.

Impacted teeth can also contribute to more than a cosmetic problem: they're more susceptible to abscesses (pockets of infection) or root damage both to themselves or neighboring teeth. To minimize these potential health issues, we'll often remove impacted teeth surgically (as is often done with wisdom teeth).

But because of their important role in not only appearance but also bite function, we may first try to assist impacted canines to fully erupt before considering extraction. It takes a bit of orthodontic "magic," but it can be done.

Before we can make that decision, though, we want to precisely locate the impacted teeth's positions and how it may affect other teeth. This initial evaluation, often with advanced diagnostics like CT scanning or digital x-rays, helps us determine if the impacted teeth are in a workable position to save. If they're not, we may then need to consider removing them and ultimately replacing them with a dental implant or similar restoration.

But if their position is workable and there are no other impediments, we can proceed with helping them erupt. To do this we'll have to first expose them by creating a small opening in the gums through minor surgery. We then bond a small bracket to the tooth, to which we'll attach a small chain that we then attach to orthodontic braces. This enables us to exert continuous pressure on the tooth.

Over time, the pressure coaxes the tooth to erupt. We may still need to apply other forms of orthodontics and cosmetic procedures, but using this procedure to rescue impacted canines can produce a healthier and more attractive smile.

NotSoFastReplacingThatTooth-ConsiderSavingitFirst

Dental implants have soared in popularity thanks to their life-likeness, functionality and durability. But these prized qualities have also created an ironic downside—people are much more likely to replace a tooth with an implant rather than go through the time and effort to preserve it.

We say downside because even though an implant is as close to a real tooth as we can now achieve in dentistry, it still can't rival the real thing. It's usually in your long-term health interest to save a tooth if reasonably possible. And, there are effective ways to do so.

Most dental problems arise from two common oral diseases. One is tooth decay, caused by contact with acid produced by bacteria living in dental plaque. We can often minimize the damage by treating the early cavities decay can create. But if we don't treat it in time, the decay can advance into the tooth's pulp chamber, putting the tooth in danger of loss.

We can intervene, though, using root canal therapy, in which we drill into the tooth to access its interior. We clean out the decayed tooth structure, remove the diseased pulp tissue and fill the empty chamber and root canals to seal the tooth and later crown it to further protect it from re-infection.

Periodontal (gum) disease also begins with bacteria, but in this case the infection is in the gum tissues. Over time the ensuing inflammation locks into battle with the plaque-fueled infection. This stalemate ultimately weakens gum attachment, the roots and supporting bone that can also increases risk for tooth loss.

We can stop a gum infection through a variety of techniques, all following a similar principle—completely removing any accumulated plaque and tartar from the teeth and gums. This stops the infection and starts the process of gum and bone healing.

You should be under no illusions that either of these approaches will be easy. Advanced tooth decay can be complex and often require the skills of an endodontist (a specialist in root canals). Likewise, gum disease may require surgical intervention. But even with these difficulties, it's usually worth it to your dental health to consider saving your tooth first before you replace it with an implant.

RootCanalsareaSafeWaytoSaveTeeth

Every year U.S. dentists perform around 25 million root canal treatments and save countless teeth from the ravages of decay. But if you search "root canal" on the Internet, you might encounter an unsettling charge against this tooth-saving treatment—that it causes cancer.

Root canal treatments are routinely used when tooth decay has infected the pulp, the innermost layer of a tooth. During the procedure, we access the pulp and remove all the infected tissue. We then fill the empty pulp and root canals, seal the access hole and later crown the tooth to prevent further infection. Without this intervention, the decay can continue to advance toward the roots and supporting bone, putting the tooth in imminent danger of loss.

So, is there any credibility to this claim that root canal treatments cause cancer? In a word, no: there's no evidence of any connection between root canal treatments and cancer—or any other disease for that matter. On the contrary: root canals stop disease.

As with other types of urban legends and internet hype, the root canal-cancer connection may have arisen from another discredited idea from the early 20th Century. A dentist named Weston Price promoted the notion that leaving a "dead" organ in the body led to health problems. From his perspective, a root canaled tooth with its removed pulp tissue fit this criterion.

In the mid-1950s, dentistry thoroughly examined Dr. Weston's theory pertaining to treatments like root canals. The Journal of the American Dental Association devoted an entire issue to it and found after rigorous scientific inquiry that the theory had no validity in this regard. Another study in 2013 confirmed those findings. In fact, the later study instead found that patients who underwent a root canal treatment had a 45 percent reduction in oral cancer risk.

Given the freewheeling nature of the Internet, it's best to speak with a dental professional about your oral health before trusting a post or article you've found online. Not only are they more informed than an unverified online source, they would certainly not knowingly subject you to a procedure to save a tooth at the expense of your health.
