With a 95-plus percent survival rate after ten years, dental implants are one of the most durable replacement restorations available. Implants can potentially last much longer than less expensive options, which could make them a less costly choice in the long run.
But although a rare occurrence, implants can and do fail—often in the first few months. And tobacco smokers in particular make up a sizeable portion of these failures.
The reasons stem from smoking’s effect on oral health. Inhaled smoke can actually burn the outer skin layers in the mouth and eventually damage the salivary glands, which can decrease saliva production. Among its functions, saliva provides enzymes to fight disease; it also protects tooth enamel from damaging acid attacks. A chronic “dry mouth,” on the other hand, increases the risk of disease.
The chemical nicotine in tobacco also causes problems because it constricts blood vessels in the mouth and skin. The resulting reduced blood flow inhibits the delivery of antibodies to diseased or wounded areas, and so dramatically slows the healing process. As a result, smokers can take longer than non-smokers to recover from diseases like tooth decay or periodontal (gum) disease, or heal after surgery.
Both the higher disease risk and slower healing can impact an implant’s ultimate success. Implant durability depends on the gradual integration between bone and the implant’s titanium metal post that naturally occurs after placement. But this crucial process can be stymied if an infection resistant to healing arises—a primary reason why smokers experience twice the number of implant failures as non-smokers.
So, what should you do if you’re a smoker and wish to consider implants?
First, for both your general and oral health, try to quit smoking before you undergo implant surgery. At the very least, stop smoking a week before implant surgery and for two weeks after to lower your infection risk. And you can further reduce your chances for failure by practicing diligent daily brushing and flossing and seeing your dentist regularly for cleanings and checkups.
It’s possible to have a successful experience with implants even if you do smoke. But kicking the habit will definitely improve your odds.

You’ve invested quite a bit in your new dental implants. And it truly is an investment: because of implants’ potential longevity, their long-term costs could actually be lower than other restorations whose upfront costs might be less.
But to better ensure their longevity, you’ll need to keep your implants and the natural tissues supporting them clean of bacterial plaque, a sticky biofilm that can cause periodontal (gum) disease. Although the implant itself is unaffected by disease, the natural tissues around it can be. An infection could ultimately weaken the bone supporting the implant and lead to its failure.
Such an infection involving implants could advance rapidly because they don’t have the natural defenses of the original teeth. Our natural teeth are connected to the jaw through the periodontal ligament, a collagen network that attaches to both the teeth and the bone through tiny tissue fibers. This connection also provides access to antibodies produced by the body to fight infection.
By contrast, we place implants directly into the jawbone. While this creates a very secure attachment, the implant won’t have the same connection as teeth with the body’s immune system. That means any infection that develops in surrounding tissues can spread much more rapidly—and so must be dealt with promptly.
Treating this particular form of gum disease (known as peri-implantitis) is similar to infections with natural teeth and gums, with one important difference involving the tools we use to remove plaque from them. While natural teeth can handle metal scalers and curettes, these can create microscopic scratches in the porcelain and metal surfaces of an implant and create havens for further bacterial growth. Instead, we use instruments made of plastic or resin that won’t scratch, as well as ultrasonic equipment to vibrate plaque loose.
To avoid an infection, it’s important that you brush your implants and surrounding tissues just like you would your natural teeth (be sure you use a soft-bristled brush). And keep up regular dental visits for thorough cleanings and checkups to stay ahead of any developing gum infection. Maintaining your dentures will help ensure they continue to brighten your smile for a long time.

While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

Dental implants are considered the best tooth replacement option available. An implant replaces the root of a tooth and allows for the replacement of the crown via attachments or abutments. They not only look like a real tooth, they function like one too.
Implants, though, for some are a significant investment and may be well beyond a person's financial means if they've experienced a sudden tooth loss. For that reason, many opt for a less expensive tooth replacement option like a removable partial denture.
Later when they can afford it, a person might consider an implant. But this could pose a complication. When a tooth is missing for some time, the underlying bone doesn't rejuvenate normally because it no longer receives stimulation from the tooth. Over time, the amount of bone may diminish. Restorations like dentures can't stop this bone loss and actually aggravates it.
For proper positioning, an implant requires a certain amount of bone volume. So, it's quite possible when the time comes to replace the old restoration with an implant that there may not be enough bone available.
We may be able to overcome this bone loss with bone grafting and regeneration. A specialist such as a periodontist or oral surgeon accesses the area surgically and inserts bone graft material, usually processed material that's completely safe. Properly placed, the bone graft serves as a scaffold that, along with growth stimulators, encourages bone cells to grow.
When the bone grafting has healed enough, we're then able to place the implant. Once imbedded in the bone, one of the implant's unique qualities comes into play. The imbedded post is made of the metal titanium, which is not only bio-compatible with body tissues, it also has an affinity with bone. Bone cells will easily grow and adhere to the implant surface. This further boosts bone growth in the area and strengthens the implant's hold.
These extra procedures to build back lost bone do add to the cost and time for installing an implant. But if you're ready for a more permanent restoration for a missing tooth — not to mention better bone health — the extra time and money will be well worth it.
While it's possible for a teenager to lose a tooth from decay, it's more common they'll lose one from an accidental knockout. If that happens to your teenager, there are some things you should know to achieve a good outcome.
Our top concern is to preserve the underlying bone following tooth loss. Like other tissues, bone has a life cycle: older cells dissolve and are absorbed by the body (resorption), then replaced by new cells. The biting pressure generated when we chew helps stimulate this growth. But bone around a missing tooth lacks this stimulation and may not keep up with resorption at a healthy rate.
This can cause a person to lose some of the bone around an empty tooth socket. To counteract this, we may place a bone graft at the site. Made of bone minerals, usually from a donor, the graft serves as a scaffold for new bone growth. By preventing significant bone loss we can better ensure success with a future restoration.
Because of its lifelikeness, functionality and durability, dental implants are considered the best of the restoration options that can be considered to replace a missing tooth. But placing an implant during the teen years is problematic because the jaws are still growing. If we place an implant prematurely it will appear to be out of alignment when the jaw fully matures. Better to wait until the jaw finishes development in early adulthood.
In the meantime, there are a couple of temporary options that work well for teens: a removable partial denture (RFP) or a fixed modified bridge. The latter is similar to bridges made for adults, but uses tabs of dental material that bond a prosthetic (false) tooth to the adjacent natural teeth to hold it in place. This alleviates the need to permanently alter the adjacent natural teeth and buy time so that the implant can be placed after growth and development has finished.
And no need to worry about postponing orthodontic treatment in the event of a tooth loss. In most cases we can go ahead with treatment, and may even be able to incorporate a prosthetic tooth into the braces or clear aligners.
It's always unfortunate to lose a tooth, especially from a sudden accident. The good news, though, is that with proper care and attention we can restore your teenager's smile.
