Dental implants have taken restorative dentistry by storm for a number of reasons: They're incredibly life-like; and their unique design allows them to function much like natural teeth. But perhaps the clincher for many is their longevity. Numerous studies show that more than 95% percent of implants are still performing after 10 years.
The reason for their durability is wrapped up in their "unique design" mentioned earlier—a titanium metal post imbedded into the jawbone, to which a dentist attaches the visible crown. The titanium attracts the growth of new bone cells, which adhere and accumulate on the implant surface.
This "integration," a process which occurs over a few weeks after implantation, creates a strong bond between the implant and jawbone. This ultra-strong hold enables the implant to withstand years, if not decades, of chewing forces you generate on a daily basis.
With that said, though, there are rare instances when an implant loses its hold—or doesn't properly develop it. Integration may not fully succeed due to infection either before or right after surgery, which can inhibit bone growth around the implant.
Other conditions can compromise the bone's integrity like a weakened immune system, diabetes or osteoporosis. And even if integration occurs normally, later problems like gum disease or a teeth-grinding habit can damage the connection between implant and bone.
There are things you can do, however, to further minimize the risk of implant failure.
- Brush and floss daily (especially around implants) and maintain regular dental visits to lower your risk of gum disease;
- See your dentist if you notice swollen, reddened or bleeding gums, an indication of a gum infection that could impact your implants;
- Stop smoking, which increases your infection risk, or abstain a few weeks before and after surgery;
- Manage issues like diabetes, osteoporosis, or teeth-grinding that could affect your implants.
Implants can be a great long-term solution to tooth loss. You can help ensure their longevity by looking out for both your oral and general health.

With traditional implant methods, it could take months before you can enjoy your new replacement tooth. That's usually not a big deal for a back tooth that's mostly out of sight. It's a different story, however, for a highly visible front tooth—the extended time without a tooth can be embarrassingly uncomfortable for some.
There is, however, another option, one you may already have seen advertised: same-day tooth replacement. In effect, you receive the implant and a life-like temporary crown in a single dental visit.
During the conventional process, the dentist surgically installs the titanium implant post into a prepared channel in the jawbone. Once it's properly positioned, the dentist then sutures the gum tissue over the implant. This protects the implant while bone cells grow and attach themselves to the post to give it a strong and durable hold within the bone.
But now dentists have developed another method to help address the appearance problem posed by teeth that are more visible. With this method, the dentist affixes a temporary crown onto the implant post immediately after installing it. The patient thus walks out the same day without a missing tooth gap and a full smile.
This is a welcome alternative for people desiring to maintain an attractive smile throughout the implant process. But it does have one major qualification—the patient's underlying jawbone must be relatively healthy and supportive of the implant. If not, the implant may require a longer period of bone growth before and after surgery to fully secure it. In those cases, it may be better to use the conventional method.
As we've already noted, a "same-day" crown isn't the permanent one, especially with single tooth implants. That's because the implant still requires bone integration over several weeks to achieve full durability. For that reason, this initial crown is made slightly shorter than the surrounding teeth to limit its encounter with biting forces generated by daily chewing, from which those forces would likely damage the implant at this stage.
After completion of the bone integration stage, the patient returns to swap out the temporary crown for the fully functional permanent crown. The "same-day" crown has served its purpose—providing the patient a seamless full smile throughout the implant process.

Upgrades can be exciting—moving on to a larger house, the latest smartphone, or maybe a new car. And, the same can apply with tooth replacements: Maybe you're ready now to upgrade your existing restoration to a dental implant, the most advanced tooth replacement method now available.
But you might encounter a speed bump in your plans: whether or not you have enough bone available for an implant. Here's why your bone may not be adequate.
Like any other cellular tissue, bone has a life cycle: older cells die and newer cells form to take their place. This process stays on track because of the forces generated when we chew, which stimulates new growth.
But that stimulus disappears when a tooth goes missing. This slows the bone growth cycle to the point that bone volume can gradually dwindle. You could in fact lose up to a quarter of bone width in just the first year after losing a tooth.
And, you'll need adequate bone to provide your implants with sufficient strength and stability, as well as the best possible appearance alongside your other teeth. If you don't have enough bone, we must either enhance its current volume or opt for a different restoration.
Fortunately, we may be able to do the former through bone augmentation or grafting. With this method, we place a graft of bone tissue in the area we wish to regenerate. The graft becomes a scaffold upon which new bone cells build upon. It's possible for grafting to produce up to 5 mm in additional width and 3 mm in height to supporting bone.
We can also use this method to prevent bone loss by placing a graft immediately following a tooth extraction. Some studies show the graft can help preserve bone up to 10 years, giving patients time to consider or prepare for a dental implant.
There are circumstances, though, where bone loss has been too extensive to make up enough ground to place an implant. If so, there are other effective and life-like restorations to replace missing teeth. But there's still a good chance augmentation can restore the bone you need for a new smile with dental implants.

Here's some good news: Teenagers are less likely than adults to lose teeth to dental disease. But there's also a flip side. Teens can still lose teeth, more likely from traumatic injury.
Fortunately, there are several options for replacing lost teeth like dentures or bridges. But the choice considered best by most dentists and patients is a dental implant. An implant tooth looks and functions like the real thing—and it's durable, capable of lasting for years, if not decades.
But there's a hitch with teens getting an implant: Even though they may have all their permanent teeth by adolescence, their jaws are still growing and developing. Natural teeth, with their attachment to the jaws by way of a periodontal ligament, can keep pace with this growth—but implants can't.
That's because an implant doesn't have this attachment to gum tissue like natural teeth, but to the jawbone alone. Hence, an implant tooth can't keep up with jaw development, and may eventually look like it's "sunk" into the gums in relation to the teeth around it.
It's best, then, to wait until a teen's jaws have fully developed before attempting an implant. In the meantime, though, they don't have to endure a smile marred by missing teeth, but can replace them with a temporary restoration. The two most common options are a partial denture or a modified bridge.
The partial denture is a lightweight version that's quite affordable. Although not as durable as other types of dentures, the appliance is only intended to last until the patient is old enough for a permanent implant.
The modified bridge is a prosthetic tooth with strips of dental material extending behind it that are bonded to the backs of the teeth on either side to hold it in place. It's likewise not as durable as a traditional bridge, but it can fill the bill until time to place an implant.
Although this adds an additional step in a teen's restorative journey after losing a tooth, it's necessary—waiting to place an implant after jaw maturity will help ensure a long-lasting result. In the meantime, a temporary tooth replacement will help them to enjoy a normal smile.

Getting dental implants is going to require surgery. But don't let that concern you—it's a relatively minor procedure.
Currently the “gold standard” for tooth replacement, an implant consists of a titanium post surgically imbedded in the jawbone. We can affix a life-like crown to a single implant or support a fixed bridge or removable denture using a series of them.
Because placement will determine the restoration's final appearance, we must carefully plan implant surgery beforehand. Our first priority is to verify that you have adequate jawbone available to support an implant.
Additionally, we want to identify any underlying structures like nerves or blood vessels that might obstruct placement. We may also develop a surgical guide, a retainer-like device placed in the mouth during surgery that identifies precisely where to create the holes or channels for the implants.
After numbing the area with local anesthesia, we begin the surgery by opening the gum tissue with a series of incisions to expose the underlying bone. If we've prepared a surgical guide, we'll place it in the mouth at this time.
We then create the channel for the insert through a series of drillings. We start with a small opening, then increase its size through subsequent drills until we've created a channel that fits the size of the intended implant.
After removing the implant from its sterile packaging, we'll directly insert it into the channel. Once in place, we may take an x-ray to verify that it's been properly placed, and adjust as needed. Unless we're attaching a temporary crown at the time of surgery (an alternate procedure called immediate loading), we suture the gums over the implant to protect it.
Similar to other dental procedures, discomfort after surgery is usually mild to moderate and manageable with pain relievers like acetaminophen or ibuprofen (if necessary, we can prescribe something stronger). We may also have you take antibiotics or use antibacterial mouthrinses for a while to prevent infection.
A few weeks later, after the bone has grown and adhered to the implant surface, you'll return to receive your new permanent crown or restoration. While the process can take a few months and a number of treatment visits, in the end you'll have new life-like teeth that could serve you well for decades.
