Dental implants have revolutionized restorative dentistry. Not only are they the top choice for individual tooth replacement, implants also improve upon traditional dental work.
Dental bridges are a case in point. A few well-placed implants can support a fixed bridge instead of natural teeth, as with a traditional bridge. Furthermore, a fixed, implant-supported bridge can replace all the teeth on a jaw.
But although convenient, we can't simply install an implant-supported bridge and forget about it. We must also protect it from what might seem at first an unlikely threat—periodontal (gum) disease.
Although the bridge materials themselves are impervious to infection, the natural tissues that underly the implants—the gums and bone—are not. An infection plaguing the gums around an implant can eventually reach the bone, weakening it to the point that it can no longer support the imbedded implants. As the implants fail, so does the bridge.
To guard against this, patients must regularly remove any buildup of plaque, a thin biofilm that feeds disease-causing bacteria, adhering to the implant surfaces in the space between the bridge and the gums. To do this, you'll need to floss—but not in the traditional way. You'll need some form of tool to accomplish the job.
One such tool is a floss threader. Similar to a large needle, the threader has an eye opening at one end through which you insert a section of floss. You then gently pass the threader between the bridge and the gums toward the tongue.
Once through, you release the floss from the threader, and holding each end, you work the floss along the implant surfaces within reach. You then repeat the threading process for other sections until you've flossed around all the implants.
You might also use a water flosser, a device that directs a spray of water between the bridge and gums. The pressure from the spray loosens and flushes away any plaque around the implants.
Whatever the method, it's important to use it every day to reduce the threat of gum disease. You should also see your dentist regularly for further cleanings and checkups. Keeping your implants clean helps ensure gum disease won't ruin your fixed bridge—or your attractive smile.

Here's some good news: Teenagers are less likely than adults to lose teeth to dental disease. But there's also a flip side. Teens can still lose teeth, more likely from traumatic injury.
Fortunately, there are several options for replacing lost teeth like dentures or bridges. But the choice considered best by most dentists and patients is a dental implant. An implant tooth looks and functions like the real thing—and it's durable, capable of lasting for years, if not decades.
But there's a hitch with teens getting an implant: Even though they may have all their permanent teeth by adolescence, their jaws are still growing and developing. Natural teeth, with their attachment to the jaws by way of a periodontal ligament, can keep pace with this growth—but implants can't.
That's because an implant doesn't have this attachment to gum tissue like natural teeth, but to the jawbone alone. Hence, an implant tooth can't keep up with jaw development, and may eventually look like it's "sunk" into the gums in relation to the teeth around it.
It's best, then, to wait until a teen's jaws have fully developed before attempting an implant. In the meantime, though, they don't have to endure a smile marred by missing teeth, but can replace them with a temporary restoration. The two most common options are a partial denture or a modified bridge.
The partial denture is a lightweight version that's quite affordable. Although not as durable as other types of dentures, the appliance is only intended to last until the patient is old enough for a permanent implant.
The modified bridge is a prosthetic tooth with strips of dental material extending behind it that are bonded to the backs of the teeth on either side to hold it in place. It's likewise not as durable as a traditional bridge, but it can fill the bill until time to place an implant.
Although this adds an additional step in a teen's restorative journey after losing a tooth, it's necessary—waiting to place an implant after jaw maturity will help ensure a long-lasting result. In the meantime, a temporary tooth replacement will help them to enjoy a normal smile.

Due to financial circumstances, people often have a lost tooth restored with a removable partial denture, an effective appliance that restores function and a degree of aesthetic appearance. Later, though, they may want to improve both function and appearance with a dental implant.
If this describes you, you’re making a great choice. Dental implants are the closest technology we have to a natural tooth. But there may be a roadblock to your implant, especially if a long time has passed since your tooth loss—there may not be enough bone at the site to place an implant.
The heart of an implant is a titanium metal post surgically imbedded in the jawbone. The titanium naturally attracts bone cells, which grow and adhere to it to form a solid hold that can support a porcelain crown or other restorations like bridges or dentures. But to achieve a natural appearance it’s important that the implant is placed in the right location. To achieve that requires adequate bone.
But there may not be adequate bone if the tooth has been missing for a while. The forces generated when we chew travel through the teeth to the jawbone, which stimulates bone growth. If that stimulus is absent because of a missing tooth, new bone cells may not replace older ones at a healthy rate and the total bone volume begins to diminish. A denture can’t compensate and, in fact, accelerates bone loss.
But there may be a solution: bone grafting. With this procedure we place a donor bone graft into the area of bone deficiency some time before implant surgery. The graft serves as a scaffold for new bone cells to grow upon. Hopefully, this will produce enough healthy bone to support an implant. If the bone deficiency is minor, we may place the implant and the bone graft at the same time.
If you have experienced bone loss, we must first determine the amount of bone at the missing tooth site and whether grafting is a viable option. Bone grafting postpones your implant, but the delay will be worth the wait if we’re successful. With increased bone volume you’ll be able to obtain a new tooth that’s superior to your current restoration.
It's a common practice among people slowly losing their teeth to have their remaining teeth removed. They find dentures to be less costly than replacing one tooth at a time or caring for those that remain. On the other hand, it's usually healthier for the mouth to preserve remaining teeth as long as possible, replacing them only as necessary.
This latter strategy has up to now been difficult and expensive to achieve. But dental implants are changing that—using these imbedded titanium metal devices with a variety of restorations, we're able to better plan and implement staged tooth replacement.
Most people associate implants with single tooth replacements of a life-like crown cemented or screwed into an abutment attached to the implant post. This can play an early role in a staged replacement plan, but at some point, multiple single-tooth implants can become quite expensive.
Implants, however, have a much broader range of use. A few strategically placed implants can support a variety of restorations, including bridges and removable or fixed dentures. Four to eight implants, for example, can secure a fixed denture replacing all teeth on a jaw, far fewer than the number needed to replace the teeth individually.
Implants may also improve the function of traditional restorations. For instance, dentures can't stop the bone loss that often results from tooth loss—in fact, they will accelerate it as they rub and irritate the bony ridges of the jaw. By contrast, implants stimulate bone growth, slowing or even stopping the process of bone loss.
In a traditional bridge, the outer crowns of the restoration are bonded to the teeth on either side of the missing tooth gap (the middle crowns fill the gap). These support teeth must be permanently altered to accommodate the crowns. But an implant-supported bridge doesn't depend on other teeth for support, thus eliminating the need to permanently alter any teeth.
More importantly, previously placed implants often become part of the next stages of tooth replacement, like building on an addition onto an existing house. All in all, including implants in your ongoing dental restoration can help you enjoy the benefits of preserving your natural teeth for much longer.

If you're thinking about getting dental implants, you may be curious about how long it might take. The answer depends on the health of your supporting bone.
Bone is an integral part of implant functionality as bone cells gradually grow and adhere to the newly placed implant to give it its characteristic strength. The implant also requires an adequate amount of bone to accurately position it for the best appearance outcome.
If the bone is sufficient and healthy, we can proceed with the surgical placement of the implant. The most common practice following surgery is to allow a few weeks for the bone integration described previously to take place before finally attaching the crown. With an alternative known as a “tooth in one day” procedure, we install a crown right after surgery, which gives you a full smile when you leave.
There's one caveat to this latter method, though—because the implant still requires bone integration, this immediate crown is temporary. It's designed to receive no pressure from biting or chewing, which could damage the still integrating implant. We'll install the permanent crown after the implant and bone have had time to fully mesh.
So, if your supporting bone is sound, the complete implant process may only take a few weeks. But what if it's not—what if you've lost bone and don't have enough to support an implant? In that case, the length of process time depends on the severity of the bone loss and if we're able to overcome it. In some cases, we can't, which means we'll need to consider a different restoration.
But it's often possible to regenerate lost bone by grafting bone material at the implant site. If the bone loss is moderate, it may take 2 to 4 months of regrowth after grafting before we can perform implant surgery. If it's more significant or there's disease damage to the socket, it may take longer, usually 4 to 6 months. It largely depends on the rate of bone regeneration.
In a nutshell, then, the health of your jaw's supporting bone has a lot to do with whether the implant process will take a few weeks or a few months. Regardless of the time, though, you'll gain the same result—new, functional teeth and a more attractive smile.
