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.

Millions of microorganisms call your mouth home—and while most are friendly, some are not. An invasive procedure like implant surgery can disrupt the mouth's soft tissues and allow disease-causing bacteria to enter the bloodstream.
This isn't necessarily a major concern if your immune system is sound—your body will move quickly to quash any developing infection. But if your body's defense is weak or compromised by other health conditions, an ensuing infection could cause you problems. In the case of a dental implant, a localized infection around it could lead to its failure.
The bone normally grows and adheres to the surface of an implant soon after it's placed, giving it the added strength and durability for which implants are best known. A bacterial infection, though, could impede bone integration and weaken the implant's hold within the jaw.
One way to avoid this is by treating patients at high risk for infection with an antibiotic before the procedure. In one recent study, researchers concluded that patients receiving a 2-gram dose of amoxicillin an hour before implant surgery helped reduce the risk of future implant failure.
But before taking this route, the dentist must first decide whether antibiotic pre-treatment might be more detrimental than beneficial to an individual patient. Antibiotics can cause side effects in certain people ranging from diarrhea to allergic reactions. Healthcare providers must also be prudent with administering antibiotics for the good of society in general—overuse can potentially give rise to antibiotic-resistant bacteria.
A number of healthcare associations highly recommend antibiotic pre-treatment for any dental patient with prosthetic heart valves, a history of infective endocarditis, a heart transplant and similar heart conditions. They also recognize patients with conditions like prosthetic joints, weakened immune systems, diabetics or other serious health problems could also benefit from antibiotic pre-treatment, but leave it to the physician's discretion on whether or not it's appropriate for an individual patient.
If you're planning to undergo implant surgery or a similar procedure and are concerned about infection, speak with your dentist about whether you would qualify and benefit from antibiotic pre-treatment. If appropriate, taking an antibiotic beforehand could minimize your infection risk.

Although costly in the beginning, dental implants often turn out to be the least expensive tooth replacement option. That's because their enviable record for longevity often outpaces dentures or bridges. Over the long-term you might spend less for implants than these other restorations.
But even with the high success rate of dental implants (greater than 95% survive the ten-year mark), we can't guarantee they won't fail. And if you're a tobacco smoker, the risk of failure might be even higher. One study, for example, found early implant failures were twice the rate for smokers over non-smokers. Although implant failures overall are low, smoking seems to be a factor in those that do.
There are a number of reasons to account for this. For one thing, inhaled smoke can damage salivary glands, reducing the flow of this important fluid. Saliva helps control bacterial growth and neutralize mouth acid, so without it you're more susceptible to tooth decay or periodontal (gum) disease. Either infection could ultimately weaken implant-supporting bone.
The nicotine in tobacco can also restrict oral blood vessels and lower their ability to supply antibodies and nutrients to the teeth and gums. This slows healing, which could have one particular effect on implant durability.
During the intervening weeks between implant placement and crown attachment, the implant's titanium post attracts bone cells that grow and adhere to its surface. The effects of nicotine on healing, especially right after implant surgery, can interfere with this integration process so that the implant doesn't anchor in the bone as well as it should.
If you're a smoker, you can increase your chances of implant success—and have a healthier mouth overall—by quitting smoking beforehand with the help of a cessation program. Or at the least, consider stopping smoking for one week before implant surgery and for two weeks afterward.
And be sure to brush and floss your teeth daily and visit your dentist regularly to keep your teeth and gums as healthy as possible. Stopping smoking and practicing effective oral hygiene could make a big difference in the success or failure of your implant.
