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.

Although they can be expensive upfront, dental implants often prove to be a wise investment in the long-term. With a success rate that outperforms other teeth replacement restorations, dental implants could be the answer to a more attractive smile that could last for decades.
But while their success rate is high (95% still functioning after ten years), they can and do occasionally fail. Of those that do, two-thirds happen in patients who smoke.
This unfortunate situation stems from smoking's overall effect on dental health. The nicotine in tobacco constricts oral blood vessels, inhibiting the flow of nutrients and antibodies to the teeth and gums. Inhaled smoke can scald the inside skin of the mouth, thickening its surface layers and damaging salivary glands leading to dry mouth.
These and other effects increase the risk for tooth decay or gum disease, which in turn makes it more likely that a smoker will lose teeth than a non-smoker and require a restoration like dental implants. And blood flow restriction caused by nicotine in turn can complicate the implant process.
Long-term implant durability depends on bone growth around the imbedded implant in the ensuing weeks after implant surgery. Because of their affinity with the titanium used in implants, bone cells readily grow and adhere to the implant. This integration process anchors the implant securely in place. But because of restricted blood flow, the healing process involved in bone integration can be impaired in smokers. Less integration may result in less stability for the implant and its long-term durability.
To increase your chances of a successful implant installation, you should consider quitting smoking and other tobacco products altogether before implant surgery. If that's too difficult, then cease from smoking for at least one week before surgery and two weeks after to better your odds of implant success. And be as meticulous as possible with daily brushing and flossing, as well as regular dental visits, to reduce your risk of disease.
There are many good reasons to quit smoking. If nothing else, do it to improve your dental health.

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.

Complete tooth loss is a common condition among older adults, gradually occurring one or two teeth at a time. There often comes a point of realization, though, that all the teeth will eventually be lost.
This can create a dilemma: Do you replace teeth as they're lost, or go ahead and have all of them removed at one time?
Up until recently, the latter choice seemed the most practical and affordable. But most dentists would agree that keeping natural teeth for as long as practical is better for a person's overall oral health and to slow any potential bone loss.
The emergence of dental implants has made this less of a dilemma: We can use this technology to more affordably replace teeth in stages rather than all at once. This is because an implant is technically a root replacement: a dentist inserts a titanium metal post into the jawbone. Because of an affinity with titanium, bone cells grow and adhere to the implant surface, which creates a stronger hold. It also impedes bone loss.
We can, of course, use implants as individual tooth replacements. But the expense of this approach with multiple teeth puts it well out of reach financially for many people. But implants can also be used as connective points between the patient's jaw and other kinds of dental restorations like bridges, partial dentures, and full removable or fixed dentures.
Using this approach, we can adopt a strategy of allowing healthier teeth to remain until it's necessary to remove them. We initially place implants to support a bridge, for example; later we can use the same implants along with additional ones to support a larger restoration, even a fixed full denture.
An implant-supported restoration is typically more expensive than traditional bridges or dentures, but far less than replacing teeth with individual implants. And because the stages of restorations may occur over a long period of time, the cost can be spread out to make it more manageable.
If you're facing a future where it's likely you'll lose all your teeth, you don't have to lose them all at once. Staged restorations with implants could help you hold on to your natural teeth for as long as possible, slow bone loss and make for a healthier mouth.

What happens when you lose a tooth? In the short-run, it can certainly undermine your appearance and ability to efficiently chew and digest food. But a chain of events could also be set in motion that may cause the most harm to your appearance and health—and it all has to do with bone loss.
Our bones aren't just rigid structures providing a frame for our bodies. They're living tissue with other purposes like producing blood cells and regulating the endocrine system. Bone tissue is constantly replenishing itself as older cells die and newer ones take their place.
In the jawbone, the pressure generated by the teeth while biting and chewing travels through the roots to stimulate the growth of new bone. If a tooth goes missing, however, the bone around the tooth also loses this growth stimulus.
This can cause normal bone growth to slow so that dying bone cells aren't sufficiently replaced. The bone may then diminish at an alarming rate—a decrease in width of about 25% in the first year after a tooth loss and several millimeters in height after only a few years.
This bone loss can continue to advance, especially if multiple teeth are lost, until the jaw structure as a whole loses significant height. The bite may then collapse, forcing the front teeth to push forward. In this state, a person may not be able to adequately bite or chew food. It can also damage their appearance—their smile suffers, of course, but their entire face may also appear shrunken.
You may be able to avoid this scenario if you replace missing teeth with dental implants. In addition to their life-likeness and durability, implants can also stop or slow bone loss. This is because titanium, the principle metal used in an implant, has a strong affinity with bone: Bone cells readily grow and attach to the titanium surface and foster new growth.
But don't wait: Bone loss could eventually extend beyond what an implant can accommodate—you may then need grafting to build up the bone or consider a different type of restoration. So, speak with your dentist as soon as possible about an implant restoration for a lost tooth to help avoid significant bone loss.
