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.

What happens when you lose a tooth? In the short-run, it can certainly undermine your appearance and ability to efficiently chew and digest food. But a chain of events could also be set in motion that may cause the most harm to your appearance and health—and it all has to do with bone loss.
Our bones aren't just rigid structures providing a frame for our bodies. They're living tissue with other purposes like producing blood cells and regulating the endocrine system. Bone tissue is constantly replenishing itself as older cells die and newer ones take their place.
In the jawbone, the pressure generated by the teeth while biting and chewing travels through the roots to stimulate the growth of new bone. If a tooth goes missing, however, the bone around the tooth also loses this growth stimulus.
This can cause normal bone growth to slow so that dying bone cells aren't sufficiently replaced. The bone may then diminish at an alarming rate—a decrease in width of about 25% in the first year after a tooth loss and several millimeters in height after only a few years.
This bone loss can continue to advance, especially if multiple teeth are lost, until the jaw structure as a whole loses significant height. The bite may then collapse, forcing the front teeth to push forward. In this state, a person may not be able to adequately bite or chew food. It can also damage their appearance—their smile suffers, of course, but their entire face may also appear shrunken.
You may be able to avoid this scenario if you replace missing teeth with dental implants. In addition to their life-likeness and durability, implants can also stop or slow bone loss. This is because titanium, the principle metal used in an implant, has a strong affinity with bone: Bone cells readily grow and attach to the titanium surface and foster new growth.
But don't wait: Bone loss could eventually extend beyond what an implant can accommodate—you may then need grafting to build up the bone or consider a different type of restoration. So, speak with your dentist as soon as possible about an implant restoration for a lost tooth to help avoid significant bone loss.

Compared to other dental restorations—a few of which have been around for over a century—implants are a relatively recent development. But even though it's just now entering its fourth decade, recent advances have catapulted implant therapy well beyond where it began.
That's due mainly to digital technology. Two examples of this, computed tomography (CT) and 3-D printing, are increasing the accuracy and efficiency of implant placement.
Properly placing an implant is one of the most important elements in achieving a natural and attractive result. But finding the best location is often difficult due to a lack of suitable bone volume, the patient's bite or the proximity of anatomical structures like nerves and blood vessels. CT imaging, especially Cone Beam CT scanners (CBCT), is helping to make implant placement planning easier.
Unlike the static, two-dimensional views of standard x-rays, CBCT takes hundreds of images and digitally blends them together to create a virtual 3-D model of the patient's jaw and face. Dentists can view this highly detailed model on a computer monitor from various vantage points and better identify possible obstructions. With better information about what "lies beneath," they can more accurately pinpoint the best implant site.
Creating the ideal plan is one thing—successfully implementing it is another. Dentists often create a surgical guide that helps them drill in precisely the right positions during surgery. The guide, which resembles a mouthguard, fits over the gums and contains marker locations for drilling.
Many dentists are now using 3-D printing to create these surgical guides. A 3-D printer turns a digital model of the guide based on measurements of the patient's mouth and proposed implant locations into an actual physical object "printed out" layer by layer of special polymer material. The end product can be more precise than guides created by other means.
These and other technological developments are helping implant therapy rise to a new level of success. With the resulting increase in accuracy, efficiency and less treatment time, tomorrow's implant patients will be the ultimate beneficiaries.
