What a difference forty years can make: Dental bridges once occupied the top spot for choices to replace missing teeth until the arrival of dental implants in the 1980s. Today, dental implants are the gold standard for dental restoration.
But although bridgework may have lost “first chair” in the orchestra of restorations, it's still a viable option. In fact, it can be the best option in certain situations.
Bridges consist of a series of porcelain crowns fused together like fence pickets. The center crowns, known as the pontics, “bridge” the gap left by a missing tooth or teeth. The crowns on each end, the abutment teeth, crown the natural teeth on either side of the gap to support the bridge.
Bridges are effective and durable, but with a major downside: To accommodate the abutment crowns, we must reduce the size of the natural teeth to which they'll be attached. This alteration can weaken those teeth's structure and require them from then on to have some form of restoration. They're also at higher risk for tooth decay.
Implants, on the other hand, don't require this alteration, and may also be more durable than bridges. Why then consider a bridge?
Price can be a factor: Implants may be more expensive, especially involving multiple teeth. Keep in mind, though, that this only compares the initial cost: Because implants have a 95% or more ten-year success rate, with further evidence they could potentially last for decades, they may actually cost less in the long-run than bridge restorations that have a higher chance of being replaced sooner.
But the prime reason is that some dental situations aren't suitable for dental implants. For instance, implants require a certain amount of bone for proper placement, so people with extensive bone loss may not be able to acquire them. Health conditions like uncontrolled diabetes or a compromised immune system can also complicate implant installation. A bridge in these cases may represent a better alternative.
With the help of your dentist, you'll need to consider your individual situation, dental and financial, in deciding between an implant or a bridge. And, if a dental bridge is your best option, it will be a solid choice for restoring your missing teeth and your smile.

Dental implants are a reliable way to replace teeth. More than 95% of implants survive ten years after their installation, and many of these could conceivably continue for decades.
But that still leaves a tiny few that don't reach the ten-year mark. Some fail early because the implant didn't integrate fully with the bone to create a durable hold. But others fail later—usually for one of two major causes.
Some failures occur due to over-stressing of the implant from abnormally high biting forces, usually because of teeth grinding. People who have this involuntary habit generate excessive force as they grind their teeth, which can damage implants (as well as natural teeth). To reduce this force, a patient's dentist can fit them with a biteguard they wear in the mouth to prevent teeth from making solid contact with each other during a grinding episode.
Fortunately, teeth grinding isn't that prevalent among adults—but that can't be said about the other major cause for implant failure: periodontal (gum) disease. This is a bacterial infection caused by dental plaque, a thin, bacterial film that accumulates on teeth. The implant itself isn't affected by the infection, but the gums and underlying bone supporting the implant can be.
Implants are most in peril from a form of gum disease called Peri-implantitis, which spreads deeper into the gum tissues around implants faster than infections around natural teeth. That's because implants lack the gum attachment of real teeth, which supply a collagen barrier that slows the spread of infection. Peri-implantitis can quickly infect the supporting bone and eventually weaken its connection with the implant.
Because of its aggressiveness and speed, we must diagnose and treat peri-implantitis as soon as possible to limit any damage to the support structures around an implant. If you notice any swollen, reddened or bleeding gums, you should call your dentist as soon as possible for an examination.
And in light of this potential danger to your implants, you should also strive to prevent gum disease through daily oral hygiene. Brushing and flossing your teeth, including around your implants, removes harmful plaque buildup. This daily habit and regular dental cleanings will help you avoid a costly gum infection and ensure your implants are there for years to come.

Daily oral hygiene and regular dental cleanings help keep your natural teeth and gums healthy and disease-free. But they're also a priority with dental implants. Here's why.
Unlike other restorations, an implant replaces both a tooth's crown and root, the latter by way of a titanium metal post imbedded into the jawbone. Bone cells grow and adhere to the metal surface, forming a secure and lasting hold.
But although quite durable, this hold differs significantly from natural teeth, which are actually held in place by a tough, elastic tissue called the periodontal ligament. The attachment of the ligament's tiny fibers to both tooth and bone secure the tooth in place, as well as supply it and the surrounding gums with nutrients and defensive antibodies to fight infection.
Implants don't have this relationship with the periodontal ligament. The tissues around an implant are thus susceptible to an aggressive form of periodontal (gum) disease called peri-implantitis. This kind of gum infection can progress rapidly, leading eventually to bone loss and possible failure of the implant.
Daily brushing and flossing of both natural and implant-supported teeth lowers the risk of gum disease, particularly peri-implantitis. It's also imperative that you undergo regular cleanings, at least every six months, with your dentist or dental hygienist.
These, however, won't be the typical cleanings performed on natural teeth. Hygienists don't use metal cleaning implements to remove plaque and tartar deposits because they can scratch the metal materials of the implant and crown. These microscopic scratches can then attract bacteria that trigger gum infections. Instead, they'll use instruments made of plastics or resins.
Hygienists also rely heavily on ultrasonic equipment that vibrates plaque loose on or around implants, which are then flushed away with water. The tips used with these instruments are also typically made of nylon or plastic sheathing.
Even with the extra hygiene care needed, implants still enjoy a 95% or higher survival rate after ten years. You can ensure your implants achieve that level of durability by keeping them clean and seeing your dentist at the first sign of a gum infection.

Complete tooth loss is a common condition among older adults, gradually occurring one or two teeth at a time. There often comes a point of realization, though, that all the teeth will eventually be lost.
This can create a dilemma: Do you replace teeth as they're lost, or go ahead and have all of them removed at one time?
Up until recently, the latter choice seemed the most practical and affordable. But most dentists would agree that keeping natural teeth for as long as practical is better for a person's overall oral health and to slow any potential bone loss.
The emergence of dental implants has made this less of a dilemma: We can use this technology to more affordably replace teeth in stages rather than all at once. This is because an implant is technically a root replacement: a dentist inserts a titanium metal post into the jawbone. Because of an affinity with titanium, bone cells grow and adhere to the implant surface, which creates a stronger hold. It also impedes bone loss.
We can, of course, use implants as individual tooth replacements. But the expense of this approach with multiple teeth puts it well out of reach financially for many people. But implants can also be used as connective points between the patient's jaw and other kinds of dental restorations like bridges, partial dentures, and full removable or fixed dentures.
Using this approach, we can adopt a strategy of allowing healthier teeth to remain until it's necessary to remove them. We initially place implants to support a bridge, for example; later we can use the same implants along with additional ones to support a larger restoration, even a fixed full denture.
An implant-supported restoration is typically more expensive than traditional bridges or dentures, but far less than replacing teeth with individual implants. And because the stages of restorations may occur over a long period of time, the cost can be spread out to make it more manageable.
If you're facing a future where it's likely you'll lose all your teeth, you don't have to lose them all at once. Staged restorations with implants could help you hold on to your natural teeth for as long as possible, slow bone loss and make for a healthier mouth.

Although costly in the beginning, dental implants often turn out to be the least expensive tooth replacement option. That's because their enviable record for longevity often outpaces dentures or bridges. Over the long-term you might spend less for implants than these other restorations.
But even with the high success rate of dental implants (greater than 95% survive the ten-year mark), we can't guarantee they won't fail. And if you're a tobacco smoker, the risk of failure might be even higher. One study, for example, found early implant failures were twice the rate for smokers over non-smokers. Although implant failures overall are low, smoking seems to be a factor in those that do.
There are a number of reasons to account for this. For one thing, inhaled smoke can damage salivary glands, reducing the flow of this important fluid. Saliva helps control bacterial growth and neutralize mouth acid, so without it you're more susceptible to tooth decay or periodontal (gum) disease. Either infection could ultimately weaken implant-supporting bone.
The nicotine in tobacco can also restrict oral blood vessels and lower their ability to supply antibodies and nutrients to the teeth and gums. This slows healing, which could have one particular effect on implant durability.
During the intervening weeks between implant placement and crown attachment, the implant's titanium post attracts bone cells that grow and adhere to its surface. The effects of nicotine on healing, especially right after implant surgery, can interfere with this integration process so that the implant doesn't anchor in the bone as well as it should.
If you're a smoker, you can increase your chances of implant success—and have a healthier mouth overall—by quitting smoking beforehand with the help of a cessation program. Or at the least, consider stopping smoking for one week before implant surgery and for two weeks afterward.
And be sure to brush and floss your teeth daily and visit your dentist regularly to keep your teeth and gums as healthy as possible. Stopping smoking and practicing effective oral hygiene could make a big difference in the success or failure of your implant.
