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.

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.

The timing around losing a tooth may not always sync with your financial ability. It's not unusual for people to postpone getting a dental implant—by far the best option for replacing a missing tooth—because of its expense.
So, if you have to postpone dental implants until you can afford them, what do you do in the meantime to keep your smile intact? One affordable option is a temporary restoration known as a flexible removable partial denture (RPD).
Composed of a kind of nylon developed in the 1950s, flexible RPDs are made by first heating the nylon and injecting its softened form into a custom mold. This creates a gum-colored denture base to which prosthetic (false) teeth are affixed at the exact locations for missing teeth.
Differing from a permanent RPD made with rigid acrylic plastic, a nylon-based RPD is flexible and lightweight, making them comfortable to wear. They're kept in place with small nylon extensions that fit into the natural concave spaces of teeth. And, with a bit of custom crafting, they can look quite realistic.
RPDs are helpful in another way, especially if you're waiting for an implant down the road: They help preserve the missing tooth space. Without a prosthetic tooth occupying that space, neighboring teeth can drift in. You might then need orthodontic treatment to move errant teeth to where they should be before obtaining a permanent restoration.
Flexible RPDs may not be as durable as acrylic RPDs, and can be difficult to repair or reline if needed to adjust the fit. Though they may not stain as readily as acrylic dentures, you'll still need to clean them regularly to help them keep looking their best. This also aids in protecting the rest of your mouth from dental disease by removing any buildup of harmful bacterial plaque on the RPD.
But even with these limitations, patients choose RPDs for the simple fact that they're affordable and temporary. And the latter is their greatest benefit—providing you a “bridge” between losing a tooth and replacing it with a durable dental implant.

Over the years, dentists have become quite proficient in treating even the most severe periodontal (gum) disease. Many of these positive outcomes are achieved through manual effort using simple hand instruments called scalars and conventional periodontal surgery.
But that might be changing soon: Periodontists (specialists who care for the gums and other supporting dental structures) are starting to use a different kind of tool for gum disease treatment—surgical lasers.
Although lasers are more commonplace in other fields of medicine, recent developments hint at a more prominent future role for them in dentistry. One of these developments is a laser procedure called Laser Assisted New Attachment Procedure (LANAP®) that treats deep spaces of infection called periodontal pockets, which develop advanced gum disease.
These pockets form as infected gums gradually detach from a tooth as the supporting bone is lost. This widens the normally narrow gap between the teeth and gums. The ensuing pocket fills with infection that must be removed to adequately treat the gum disease. As the pocket extends down to the root, it's often necessary to perform a surgical procedure through the adjacent gum tissue to fully access it.
But with the LANAP® procedure, the dentist can use a laser to access a deep pocket without opening the gums. Moving from above into the gap between the tooth and gums, the light from the laser has the ability to remove diseased tissue without damaging healthy tissue.
The dentist follows this with ultrasonic equipment and manual scalers to further decontaminate the tooth root surface. The laser is then employed once again to facilitate the formation of a blood clot between the teeth and gums to seal the area with a fibrin clot. Once treated, the dentist will monitor the tooth to ensure maximum bone regeneration and gum reattachment.
Although outcomes are the same for the most part, this laser technique for periodontal pockets may have some advantages over conventional surgery. Studies so far show that LANAP® causes less tissue removal and bleeding, less potential for gum recession and less discomfort experienced by patients.
It's not likely that lasers will fully replace conventional gum disease treatments any time soon. But if the encouraging evidence thus far continues, the laser will one day become as commonplace alongside the other tools used for gum disease treatment.

Ashley Graham has a beautiful and valuable smile—an important asset to her bustling career as a plus-size model and television host. But she recently revealed on Instagram a “confrontation” between one of her teeth and a frozen oatmeal cookie. The cookie won.
Holding her hand over her mouth during the video until the last moment, Graham explained how she sneaked a cookie from her mom's freezer and took a bite of the frozen treat. Taking her hand from her mouth, she revealed her broken tooth.
Okay, maybe it wasn't an actual tooth that was broken: the denticle in question appeared to have been previously altered to accommodate a porcelain veneer or crown. But whatever was once there wasn't there anymore.
Although her smile was restored without too much fuss, Graham's experience is still a cautionary tale for anyone with dental work (and kudos to her for being a good sport and sharing it). Although dental work in general is quite durable, it is not immune to damage. Biting down on something hard, even as delicious as one of mom's frozen oatmeal cookies, could run you the risk of popping off a veneer or loosening a crown.
To paraphrase an old saying: Take care of your dental work, and it will take care of you. Don't use your teeth in ways that put your dental work at risk, tempting as it may be given your mouth's mechanical capabilities.
Even so, it's unwise—both for dental work and for natural teeth—to use your teeth and jaws for tasks like cracking nuts or prying open containers. You should also avoid biting into foods or substances with hard textures like ice or a rock-hard cookie from the freezer, especially if you have veneers or other cosmetic improvements.
It's equally important to clean your mouth daily, and undergo professional cleanings at least twice a year. That might not seem so important at first since disease-causing organisms won't infect your dental work's nonliving materials. But infection can wreak havoc on natural tissues like gums, remaining teeth or underlying bone that together often support dental enhancements. Losing that support could lead to losing your dental work.
And it's always a good idea to have dental work, particularly dentures, checked regularly. Conditions in the mouth can change, sometimes without you noticing them, so periodic examinations by a trained dental provider could prevent or treat a problem before it adversely affects your dental work.
We're glad Ashley Graham's trademark smile wasn't permanently harmed by that frozen cookie, and yours probably wouldn't be either in a similar situation. But don't take any chances, and follow these common sense tips for protecting your dental work.
