While anyone can lose a permanent tooth, the cause often varies by age group. Adults usually lose their teeth to disease, while those under twenty lose a tooth to accidents.
For adults, a dental implant is usually the best way to replace a missing tooth. Teenagers and younger, on the other hand, must wait to get implants until their jaws fully develop. An implant placed on an immature jaw will eventually look and feel out of place.
For most, their jaws won't reach full maturity until their early twenties. Even so, they still have a couple of good options for restoring their smiles in the meantime, albeit temporarily.
One is a removable partial denture or RPD, a device with the replacement prosthetic (false) tooth or teeth set in a gum-colored acrylic base. Of the various types of RPDs, most teenagers do well with a rigid but lightweight version called a “flipper,” called so because it can be flipped in and out of place with the tongue.
These RPDs are affordable, their fit easily adjusted, and they make cleaning the rest of the teeth easier. But they can break while biting down hard and—because they're dentures—aren't always well accepted among teenagers.
The other option is a bonded bridge. Unlike a traditional bridge secured with crowns cemented to natural teeth, a bonded bridge uses a strip of dental material affixed to the back of the prosthetic tooth with the ends of the strip extending outward horizontally. With the prosthetic tooth inserted into the empty space, these extended ends are bonded to the backs of the natural teeth on either side.
Though not as secure as a traditional bridge, a bonded bridge is more aesthetic and comfortable than an RPG. On the other hand, patients who have a deep bite or a teeth-grinding habit, both of which can generate abnormally high biting forces, run a higher risk of damaging the bridge. A bridge can also make hygiene tasks difficult and time-consuming, requiring a high degree of self-discipline from the patient.
Whichever you choose, both options can effectively replace a teenager's missing tooth while waiting for dental implants. Although temporary, they can make the long wait time for a teenager more bearable.
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.

Soon after the primary (baby) teeth begin to give way, the teeth a child will have the rest of their lives start erupting into the mouth. But while they’re permanent, they’re not as strong and developed as they will be in adulthood.
That’s why we treat young permanent teeth differently from older adult teeth. For example, a decayed adult tooth may need a root canal treatment; but this standard treatment would often be the wrong choice for a child’s tooth.
The reason why involves the pulp, the innermost layer of a tooth, which plays a critical role in early development. Young permanent teeth continue to grow in sync with the jaws and facial structure. Most of this growth is in the dentin, the layer between the enamel and pulp, which increases proportionally to the other layers as the tooth matures. The pulp generates this new dentin.
A root canal treatment completely removes the diseased tissue of the pulp. This isn’t a major issue for a mature tooth because it no longer needs to generate more dentin. But it can have long-term consequences for an immature tooth whose growth may become stunted and the roots not fully formed. The tooth may thus become brittle and darkened, and might eventually require removal.
Because of these potential consequences, a root canal treatment is a last resort for a young permanent tooth. But there are modified alternatives, depending on the degree of pulp exposure or infection. For example, if the pulp is intact, we may be able to remove as much soft decayed dentin as we can, place an antibacterial agent and then fill the tooth to seal it without disturbing the pulp. If the pulp is partially affected, we can remove that part and place substances that encourage dentin growth and repair.
Our main goal is to treat a young tooth with as little contact with the pulp as possible, so as not to diminish its capacity to generate new dentin. Avoiding a full root canal treatment if at all possible by using these and other techniques will help ensure the tooth continues to develop to full maturity.

Porcelain veneers have been used for several decades to enhance a dental patient's smile. These thin wafers of color-matched dental porcelain are bonded to the visible surface of teeth to mask chips, disfigurements, discoloring or slight misalignments and gaps. Thanks to the artistry of dentists and dental lab technicians, the average observer often can't distinguish a veneered tooth from a natural one.
Veneers are great—but they're even more life-like and versatile thanks to recent technological advances. Here are a few of these high tech means that can help make your veneers as attractive as possible.
Digital photography. There's a lot that goes into making sure an individual's veneers seamlessly blend in with other teeth. Photographs in digital form that can be transferred electronically to dental labs are invaluable, especially for accurate color matching. A high resolution photograph can also relay an enormous amount of information about a patient's existing teeth including shape, size, length and position.
Computer imaging. We want you to be satisfied with your final veneer appearance. The best way to ensure that—and to relax any jitters you may have over the process—is to enable you to “see” your new smile before your veneers are even made. We can do that with computer imaging software that modifies a current photo of your smile to look as it will be with veneers. It's also a great tool for making changes to the veneer plan based on what you see in the model.
Tryout veneers. We can even take it a step further, by letting you see how your proposed veneers will look like on your own teeth. We do this by creating provisional veneers made of composite materials that we temporarily bond to your teeth. You can try them out for a while (and get others' impressions) until your permanent veneers are ready. And as with computer imaging, tryout veneers can guide updates to your veneer schematics before they're made.
Using these and other advanced techniques can help fine-tune the design of your new veneers to make sure they're the best they can be. They're great tools in achieving our ultimate goal with your veneers—a beautiful smile that everyone thinks is natural.

Before implants, people often turned to a removable appliance to replace multiple missing teeth. Known as a removable partial denture (RPD), this appliance could restore both appearance and function at an affordable price.
But although implants may have diminished their use, RPDs haven't gone extinct. They're still a viable option for patients who can't afford implants or fixed bridgework, or who can't obtain implants due to the state of their dental health.
Although replacing only a few teeth rather than an entire arch, RPDs are similar in basic concept to full dentures. The prosthetic (artificial) teeth are anchored in a resin or plastic that's colored to resemble the gums, precisely placed to fit into the missing gaps. This assembly is further supported by a frame made of vitallium, a lightweight but strong metal alloy. The appliance fits upon the arch with the missing teeth, supported by vitallium clasps that grip adjacent natural teeth.
Each RPD must be custom designed for each patient to fit perfectly without excessive movement during chewing. Too much movement could warp the fit, reduce the RPD's durability or damage other teeth. To achieve this secure fit, dentists must take into account the number and location of missing teeth to be replaced, and then apply a specific construction pattern to balance the appliance.
There are RPDs that are meant to be used short-term, as with a teenager whose jaw isn't yet mature for dental implants. But the metal-framed RPDs we've described are designed for long-term use. There is, however, one primary downside: RPDs have a propensity to collect dental plaque, a thin biofilm most responsible for dental disease that could further deteriorate your dental health.
To avoid this, you'll need to keep both the RPD and the rest of your teeth and gums as clean as possible with daily brushing and flossing, and appliance care. And like dentures, it's best to remove the RPD when you go to bed at night to discourage the growth of harmful bacteria.
To see if an RPD to replace your missing teeth is an option for you, visit us for a complete dental exam. From there, we can advise you further as to whether an RPD could affordably restore your missing teeth and your smile.
