Although getting an implant requires surgery, it's usually a minor affair. Chances are good that after just a few days recuperation you'll be back completely to your normal activities.
But like many other minor surgeries, an implant procedure does pose a slight risk of post-op infection. That's especially so with any dental procedure like implant surgery, since the mouth harbors numerous strains of bacteria that could escape into the bloodstream. For most people, though, a post-op infection doesn't pose a major problem since their immune system kicks in immediately to defeat it.
But some patients with less than robust immune systems or other health problems can have serious complications from an infection. Among other things, infected tissues around an implant may not heal properly, putting the implant at significant risk for failure.
If you have a condition that makes a post-op infection problematic, your dentist or physician may recommend you take an antibiotic before your procedure. Known as prophylactic (preventive) antibiotic treatment, it's intended to give a weakened immune system a head-start on any potential infection after a procedure.
Using antibiotics in this way has been a practice for several decades, and at one time were recommended for a wide list of conditions. That's changed in recent years, though, as evidence from numerous studies seems to show the risk to benefit ratio isn't significant enough to warrant its use in all but a handful of conditions.
Both the American Dental Association and the American Heart Association recommend prophylactic antibiotics for patients with prosthetic heart valves, past infective endocarditis, a heart transplant and some congenital heart conditions. Some orthopedists may also recommend it for patients with prosthetic joints.
Even if you don't fall into these particular categories, prophylactic antibiotics may still be beneficial if you have a compromised immune system or suffer from a disease like diabetes or lung disease. Whether or not a prophylactic antibiotic is a prudent step given your health status is a discussion you should have with both your physician and your dentist.
If they feel it's warranted, it can be done safely in recommended doses. If your health isn't as robust as it could be, the practice could give you a little added insurance toward a successful implant outcome.

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.

Introduced to the United States in the 1980s, dental implants have quickly become the go-to restoration for tooth replacement. And for good reason: they're not only incredibly life-like, they're highly durable with a 95% success rate.
But as desirable as they are, you may face a major obstacle getting one because of the condition of the bone at your implant site. To position the implant for best appearance and long-term durability, we must have at least 4-5 mm of bone available along the horizontal dimension. Unfortunately, that's not always the case with tooth loss.
This is because bone, like other living tissue, has a growth cycle: Older cells die and dissolve (resorb) and newer cells develop in their place. The forces transmitted to the jaw from the action of chewing help stimulate this resorption and replacement cycle and keep it on track. When a tooth is lost, however, so is this stimulus.
This may result in a slowdown in cell replacement, causing the eventual loss of bone. And it doesn't take long for it to occur after tooth loss—you could lose a quarter of bone width in just the first year, leaving you without enough bone to support an implant. In some cases, it may be necessary to choose another kind of restoration other than implants.
But inadequate bone isn't an automatic disqualifier for implants. It's often possible to regenerate lost bone through a procedure known as bone augmentation, in which we insert a bone graft at the missing tooth site. The graft serves as a scaffold for new bone cells to grow upon, which over time may regenerate enough bone to support an implant.
Even if you've had a missing tooth for some time, implementing bone augmentation could reverse any loss you may have experienced. In fact, it's a common practice among dentists to place a bone graft immediately after a tooth extraction to minimize bone loss, especially if there will be a time lag between extraction and implant surgery.
Bone augmentation could add extra time to the implant process. But if successful, it will make it possible for you to enjoy this popular dental restoration.

Daily oral hygiene and regular dental cleanings help keep your natural teeth and gums healthy and disease-free. But they're also a priority with dental implants. Here's why.
Unlike other restorations, an implant replaces both a tooth's crown and root, the latter by way of a titanium metal post imbedded into the jawbone. Bone cells grow and adhere to the metal surface, forming a secure and lasting hold.
But although quite durable, this hold differs significantly from natural teeth, which are actually held in place by a tough, elastic tissue called the periodontal ligament. The attachment of the ligament's tiny fibers to both tooth and bone secure the tooth in place, as well as supply it and the surrounding gums with nutrients and defensive antibodies to fight infection.
Implants don't have this relationship with the periodontal ligament. The tissues around an implant are thus susceptible to an aggressive form of periodontal (gum) disease called peri-implantitis. This kind of gum infection can progress rapidly, leading eventually to bone loss and possible failure of the implant.
Daily brushing and flossing of both natural and implant-supported teeth lowers the risk of gum disease, particularly peri-implantitis. It's also imperative that you undergo regular cleanings, at least every six months, with your dentist or dental hygienist.
These, however, won't be the typical cleanings performed on natural teeth. Hygienists don't use metal cleaning implements to remove plaque and tartar deposits because they can scratch the metal materials of the implant and crown. These microscopic scratches can then attract bacteria that trigger gum infections. Instead, they'll use instruments made of plastics or resins.
Hygienists also rely heavily on ultrasonic equipment that vibrates plaque loose on or around implants, which are then flushed away with water. The tips used with these instruments are also typically made of nylon or plastic sheathing.
Even with the extra hygiene care needed, implants still enjoy a 95% or higher survival rate after ten years. You can ensure your implants achieve that level of durability by keeping them clean and seeing your dentist at the first sign of a gum infection.
