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.

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 far and away the most “tooth-like” restoration available today for missing teeth. Not only do they look real, they also mimic dental anatomy in replacing the tooth root.
To install an implant, though, requires a minor surgical procedure. And, as with any surgery, that includes a slight risk for a post-surgical infection. For most patients this isn't a major concern—but it can be for people with certain medical conditions.
One way to lessen the risk for implant patients whose health could be jeopardized by an infection is to prescribe a prophylactic (preventive) antibiotic before implant surgery. The American Dental Association (ADA) recommends the measure for patients with artificial heart valves, a history of infective endocarditis, a heart transplant and other heart-related issues.
In the past, their recommendation also extended to people with joint replacements. But in conjunction with the American Academy of Orthopedic Surgery (AAOS), the ADA downgraded this recommendation a few years ago and left it to the physician's discretion. Indeed, some orthopedic surgeons do recommend antibiotic therapy for patients before surgical procedures like implantation for up to two years after joint replacement.
These changes reflect the ongoing debate over the proper use of antibiotics. In essence, this particular argument is over risks vs. benefits: Are pre-surgical antibiotics worth the lower infection risk for patients at low to moderate risk in return for increased risk of allergic reactions and other side effects from the antibiotic? Another driver in this debate is the deep concern over the effect current antibiotic practices are having on the increasing problem of antibiotic-resistant bacteria.
As a result, dentists and physicians alike are reevaluating practices like prophylactic antibiotics before procedures, becoming more selective on who receives it and even the dosage levels. Some studies have shown, for example, that a low 2-gram dose of amoxicillin an hour before the procedure can be effective with much lower risks for side effects.
If you're considering dental implants and you have a medical condition you think could be impacted by the procedure, discuss the matter with your dentist and physician. It may be that pre-surgical antibiotics would be a prudent choice for you.

Dental implants aren't simply prosthetic teeth, but rather an innovative system that restores both smile appearance and dental function. And while an implant can indeed replace a single tooth, they can do so much more. Integrated with removable dentures or a fixed bridge, they provide a secure solution to multiple missing teeth.
Implants essentially replace a missing tooth's root, the basis for their lifelikeness and functionality. As such, they're also the most sophisticated restoration used today, requiring a high degree of technical and aesthetic skill to place them properly. In reality, implantation is more a process than a procedure.
If you're considering implants, that process begins with a comprehensive dental exam. During the exam, we'll assess the exact condition of your oral and facial structures like the length of remaining teeth, your bite and jaw dimensions. We'll use this information to plan the type and placement of your implants. The exam may also reveal problems like bone loss that might postpone your implants or suggest another form of restoration.
Using digital technology, we then locate the exact positions for your implants on the jaw to ensure the best outcome. This often results in the creation of a surgical guide, a plastic template placed over the jaw that accurately pinpoints the locations for the drilling sequence during implant surgery.
In most cases once the implants are surgically installed, gum tissue may be sutured over the implant to protect it while it integrates with the bone. In some cases, though, a visible crown may be placed immediately, so the patient can enjoy a tooth-filled smile the same day. This immediate crown, though, is temporary and will be replaced with a more durable, permanent one in a few months.
During this interim, the titanium in the implant post will attract bone cell growth, which will build up on the implant surface. This increased bone contact will help secure the implant fully in the jaw, giving the implant its signature durability.
Once the integration is complete, the permanent crown is affixed to the implant (or implants in the case of a fixed or removable dental appliance). It may have been a long road, but you'll have the closest thing to real teeth.

You would love to replace a troubled tooth with a dental implant. But you have one nagging concern: you also have diabetes. Could that keep you from getting an implant?
The answer, unfortunately, is yes, it might: the effect diabetes can have on the body could affect an implant's success and longevity. The key word, though, is might—it's not inevitable you'll encounter these obstacles with your implant.
Diabetes is a group of metabolic diseases that interfere with the normal levels of blood glucose, a natural sugar that is the energy source for the body's cells. Normally, the pancreas produces a hormone called insulin as needed to regulate glucose in the bloodstream. A diabetic, though either can't produce insulin or not enough, or the body doesn't respond to the insulin that is produced.
And while the condition can often be managed through diet, exercise, medication or supplemental insulin, there can still be complications like slow wound healing. High glucose can damage blood vessels, causing them to deliver less nutrients and antibodies to various parts of the body like the eyes, fingers and toes, or the kidneys. It can also affect the gums and their ability to heal.
Another possible complication from diabetes is with the body's inflammatory response. This is triggered whenever tissues in the body are diseased or injured, sealing them off from damaging the rest of the body. The response, however, can become chronic in diabetics, which could damage otherwise healthy tissues.
Both of these complications can disrupt the process for getting an implant. Like other surgical procedures, implantation disrupts the gum tissues. They will need to heal; likewise, the implant itself must integrate fully with the bone in which it's inserted. Both healing and bone integration might be impeded by slow wound healing and chronic inflammation.
Again, it might. In reality, as a number of studies comparing implant outcomes between diabetics and non-diabetics has shown, there is little difference in the success rate, provided the diabetes is under control. Diabetics with well-managed glucose can have success rates above 95%, well within the normal range.
An implant restoration is a decision you should make with your dentist. But if you're doing a good job managing your diabetes, your chances of a successful outcome are good.
