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.

Getting a new implant tooth in only one day sounds too good to be true. But it's true—up to a point. Whether or not you can undergo an immediate crown replacement (attaching a crown to an implant right after surgery) will depend mostly on the underlying bone.
Traditionally, an implant crown isn't attached until several weeks after surgery to allow bone cells to grow and adhere to an implant's titanium surface (osseointegration). The gums are sutured back in place to protect the metal implant until it develops a durable hold within the bone. But this also leaves you with a noticeable missing tooth gap during the integration period.
A “tooth in a day” procedure gives you a full smile right after implant surgery. There is one catch, though—this first crown will be temporary and it won't be able to receive biting pressure.
Until the bone and implant fully integrate, attaching a full-sized permanent crown can damage the implant. To avoid this, the initial crown is slightly shorter than the future permanent crown. This prevents it from contacting solidly with teeth on the other jaw while biting or chewing, which can generate enough force to potentially damage the implant.
If you undergo an immediate-load crown on your implant, you'll have to return later for the full-length permanent crown. In the meantime, though, you'll avoid the embarrassment of a missing tooth in your smile.
With that said, the target bone must be healthy and intact for you to undergo a “tooth in a day” procedure. That isn't always the case with missing teeth—over time, bone volume can gradually diminish. The subsequent loss can complicate implant placement, which must be exact to achieve the most natural outcome. If extensive bone loss exists, you may need grafting to build up enough bone to adequately support an implant.
Even if an implant can be placed, the bone may still be too weak to allow for immediate crown placement. In that case, the traditional procedure may be the best course to allow the bone and implant to fully bond.
To determine if you're a candidate for a “tooth in a day” implant procedure, you'll first need to have a thorough dental exam that includes an assessment of bone health. If it's sound, you may be able to have a full smile right after implant surgery.

After years battling disease, your troubled tooth reached its useful life's end. It's been extracted, and we've replaced it with a life-like dental implant. So now, as far as the implant goes, disease is no longer an issue…right?
Sorry, no—though not to the same degree as a natural tooth, an implant could be endangered by gum disease. Although the implant's materials can't be infected, the supporting gums and bone can.
In fact, there's a particular type of gum disease associated with implants known as peri-implantitis (“peri” around an implant; “itis” inflammation) that first affects the gums surrounding an implant. Although peri-implantitis can arise from an excess of dental cement used to affix the crown to the implant, it most commonly starts like other forms of gum disease with dental plaque.
Dental plaque, and its hardened form calculus (tartar), is a thin, bacterial biofilm that builds up on teeth surfaces. It can quickly accumulate if you don't remove it every day with proper brushing and flossing. The bacteria living in plaque can infect the outer gum tissues and trigger inflammation.
Gum disease around natural teeth can spread quickly, but even more so with implants. That's because the natural attachment of the gums helps supply antibodies that impede infection. Implants, relying solely on their connection with the bone, don't have those gum attachments. As a result, peri-implantitis can move rapidly into the supporting bone, weakening the implant to the point of failure.
The good news, though, is that peri-implantitis can be treated successfully through aggressive plaque removal and antibiotics. But the key to success is to catch it early before it progresses too far—which is why you should see your dentist at the first sign of gum swelling, redness or bleeding.
You can also prevent peri-implantitis by practicing daily brushing and flossing, including around your dental implant. You should also see your dentist twice a year (or more, if they advise) for cleanings and checkups.
Dental implants overall have a greater than 95% success rate, better than any other tooth restoration system. But they still need daily care and regular cleanings to ensure your implants are on the positive side of those statistics.
Years ago, disease or trauma robbed you of one of your teeth. At the time you might have opted for an affordable solution, like a partial denture. But now you'd like to restore that missing tooth with a dental implant, the most life-like tooth replacement available.
That's a great decision. But there may be a hiccup along the way to your new implant: the state of the underlying jawbone. Implants need a certain amount of bone for proper placement. If not enough is present, that may cause an interruption in your plans—and that could be a real possibility if your tooth has been missing for some time.
That's because, like other living tissues, bone has a growth cycle: Old bone cells die and dissolve, while new cells form to take their place. In the jaw, the force produced by teeth during chewing helps to keep this growth process in the bone functioning at a healthy pace.
When a tooth goes missing, though, so does this chewing stimulation. A lack of stimulation can slow the growth rate for that part of the bone and its volume can diminish over time. It's possible for a quarter of the bone volume to be lost within the first year after losing a tooth.
If you've experienced that level of bone loss, we may not be able to place an implant—yet. You might still have a few options. For one, we could attempt to regenerate some of the bone through grafting. Bone material grafted into the affected area can serve as a scaffold for new bone cells to form and adhere. Over time, this could result in a sufficient amount of regenerated bone to support a dental implant.
Another possibility might be to install a smaller diameter implant like those used to support removable dentures. Because they're smaller they require less bone than standard-sized implants. They're not for every situation, though, and are best suited for situations where aesthetics isn't a priority.
To know what your options are regarding an implant-based restoration, you'll need to undergo a thorough evaluation of your oral health, including supporting bone. Depending on your situation, you may still be able to renew your smile with this premier tooth replacement option.

Losing teeth continues to be an all too common experience for people, especially those in their senior years. Fortunately, there are several ways to replace them, ranging from partial or full dentures to implants.
Some, though, postpone or simply choose not to replace a lost tooth, often because of the cost. But putting off a dental restoration could have a long-term impact on your health, and not in a good way. Continuing bone deterioration is one of the top consequences of delayed restoration.
Like other bones in the body, the jawbone is living tissue with cells that form, grow and eventually wear out. At the end of their life, these older cells give way to new cells. Eating and chewing play an important role in maintaining this growth cycle: the forces we generate as we chew travel up through the tooth roots to stimulate bone growth in the jaw.
When a tooth goes missing, though, the stimulus ends. Over time the bone cell replacement rate can fall off and the bone slowly loses volume. To make matters worse, bone loss can continue beyond the immediate bone underlying the tooth and affect the rest of the jawbone. The jaw can shrink in height and width, and in time become weaker overall and more susceptible to fracture.
But dental implant restorations in particular could help stop or even reverse bone deterioration at the site of the missing teeth. The titanium post implanted in the jaw attracts bone cells, which grow and adhere to its surface. Over time the bone fills in and becomes stronger.
You don't want to wait too long, though, because implants depend on a minimum amount of bone present for secure placement. You should therefore undergo an implant restoration as soon as it's practical after tooth loss. Otherwise, although we may be able to restore some of the lost bone with bone grafting, you may need to consider another restorative option.
When it comes to replacing missing teeth, time isn't on your side. But the right kind of dental restoration undertaken promptly can make for a brighter, healthier future.
