Implant-supported fixed bridges are growing in popularity because they offer superior support to traditional bridges or dentures. They can also improve bone health thanks to the affinity between bone cells and the implants' titanium posts.
Even so, you'll still need to stay alert to the threat of periodontal (gum) disease. This bacterial infection usually triggered by dental plaque could ultimately infect the underlying bone and cause it to deteriorate. As a result the implants could loosen and cause you to lose your bridgework.
To avoid this you'll need to be as diligent with removing plaque from around your implants as you would with natural teeth. The best means for doing this is to floss around each implant post between the bridgework and the natural gums.
This type of flossing is quite different than with natural teeth where you work the floss in between each tooth. With your bridgework you'll need to thread the floss between it and the gums with the help of a floss threader, a small handheld device with a loop on one end and a stiff flat edge on the other.
To use it you'll first pull off about 18" of dental floss and thread it through the loop. You'll then gently work the sharper end between the gums and bridge from the cheek side toward the tongue. Once through to the tongue side, you'll hold one end of the floss and pull the floss threader away with the other until the floss is now underneath the bridge.
You'll then loop each end of the floss around your fingers on each hand and work the floss up and down the sides of the nearest tooth or implant. You'll then release one hand from the floss and pull the floss out from beneath the bridge. Rethread it in the threader and move to the next section of the bridge and clean those implants.
You can also use other methods like specialized floss with stiffened ends for threading, an oral irrigator (or "water flosser") that emits a pressurized spray of water to loosen plaque, or an interproximal brush that can reach into narrow spaces. If you choose an interproximal brush, however, be sure it's not made with metal wire, which can scratch the implant and create microscopic crevices for plaque.
Use the method you and your dentist think best to keep your implants plaque-free. Doing so will help reduce your risk of a gum infection that could endanger your implant-supported bridgework.

While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

There are several reasons why dental implants are so popular. Perhaps the most important, though, is their longevity: if maintained properly implants can last for decades. However, they’re not indestructible—certain mouth conditions could put them at risk for early failure. But if you address emerging problems early, you may be able to prevent that unfortunate outcome.
Your implants may be in danger, for example, if you have a teeth grinding or clenching habit. This occurs when a person involuntarily and repeatedly bites down on their teeth when not chewing or speaking. Usually triggered in adults by high stress, teeth grinding can subject both natural teeth and implants to damaging levels of force. Over time this can cause bone loss around an implant and weaken their support. It could also cause a direct break in an implant.
But there are ways to stop or at least reduce the effects of teeth grinding. One effective way is a custom-made bite guard you wear while you sleep. Made of hard plastic, the guard prevents the teeth from making solid contact with each other, reducing the amount of force generated.
A more prominent problem is periodontal (gum) disease, a bacterial infection caused by built-up dental plaque on tooth surfaces. This can trigger inflammation, a normal defensive response that when it persists for an extended period of time can damage tissues and supporting bone. It can also cause a specific form of gum disease related to implants called peri-implantitis, in which the tissues that support an implant become infected and weaken, leading eventually to possible implant failure.
If you have implants, then, you should brush and floss daily to prevent gum disease, as well as see your dentist at least every six months for cleanings and checkups. And if you notice anything like reddened, swollen or bleeding gums, see your dentist immediately. The sooner you undergo treatment, the better the outcome for your implants as well as your overall health.
Dental implants can give you years of great service and can prove to be well worth the cost. But you’ll have to stay on your guard against gum disease and other mouth conditions that could endanger them down the road.

If you’re considering a dental implant as a replacement for a lost tooth, you’re looking at a restoration method with an amazing 95% success rate after ten years. But that being said there’s still a risk, albeit quite low, the implant might fail.
And if you smoke, the risk is slightly higher. In a recent study of implant patients, twice as many of the failures occurred in smokers compared to non-smokers. If you’re a smoker, you can increase your chances of a successful outcome if you quit the habit.
Nicotine, a chemical within tobacco, is the primary cause for this higher risk. Besides its effect on the pleasure centers of the brain, nicotine also restricts smaller blood vessels that are abundant in the mouth and skin, causing less blood flow. As a result, the mouth doesn’t have as many antibodies and other substances available to fight infection and help traumatized tissues heal.
Because of this, as well as reduced saliva flow due to the habit, smokers have an increased risk of dental disease and are slower to respond to treatment. This can be especially problematic if the gum tissues around an implant become infected, which could lead to a catastrophic failure. Slower healing also impacts the post-surgery period when bone cells in the jaw are growing and adhering to the implant surface, forming a stronger bond.
To avoid these potential risks you should stop smoking before you undergo implant surgery. If you can’t completely kick the habit, you should at least stop a week before surgery and for two weeks after. It’s also critical that you practice good oral hygiene — both brushing and flossing — to minimize the occurrence of dental disease and see us for regular checkups and maintenance appointments.
Taking these steps will greatly increase your chances of being in the vast majority of people who continue to enjoy success with their implants for many years.

For generations, dentures have helped people avoid the dire consequences of total teeth loss. Now, implant technology is making them even better.
Composed of life-like prosthetic teeth fixed within a plastic or resin gum-colored base, dentures are manufactured to fit an individual patient’s mouth for maximum fit, comfort and performance. But dentures also have a critical drawback—they can’t stop bone loss in the jaw.
Bone is constantly regenerating as older cells dissolve and then are replaced by newer cells. In the jawbone, the forces generated when we chew travel through the teeth to the bone and help stimulate this new cell growth. When teeth are missing, though, the bone doesn’t receive this stimulus and may not regenerate at a healthy rate, resulting in gradual bone loss.
Dentures can’t transmit this chewing stimulus to the bone. In fact, the pressure they produce as they rest on top of the gums may actually accelerate bone loss. Over time then, a denture’s once secure and comfortable fit becomes loose.
In the past, most patients with loose dentures have had them relined with new dental material to improve fit, or have new dentures created to conform to the changed contours of the jaws. But implant technology now offers another alternative.
Implants are in essence a tooth root replacement. Dentists surgically implant a titanium metal post directly into the jawbone that naturally attracts bone cells to grow and adhere to it over time (a process called osseointegration). This not only creates a secure and lasting hold, it can also stop or even reverse bone loss.
Most people know implants as single tooth replacements with a porcelain crown attached to the titanium post. But a few strategically placed implants can also support either removable or fixed dentures. Removable dentures (also called overdentures) usually need only 3 or 4 implants on the top jaw and 2 on the bottom jaw for support through built-in connectors in the dentures that attach to the implants. A fixed bridge may require 4-6 implants to which they are permanently attached.
There are pros and cons for each of these options and they’re both more expensive than traditional dentures. In the long run, though, implant-supported dentures could be more beneficial for your bone health and hold their fit longer.
