Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

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.

In real life he was a hard-charging basketball player through high school and college. In TV and the movies, he has gone head-to-head with serial killers, assorted bad guys… even mysterious paranormal forces. So would you believe that David Duchovny, who played Agent Fox Mulder in The X-Files and starred in countless other large and small-screen productions, lost his front teeth… in an elevator accident?
“I was running for the elevator at my high school when the door shut on my arm,” he explained. “The next thing I knew, I was waking up in the hospital. I had fainted, fallen on my face, and knocked out my two front teeth.” Looking at Duchovny now, you’d never know his front teeth weren’t natural. But that’s not “movie magic” — it’s the art and science of modern dentistry.
How do dentists go about replacing lost teeth with natural-looking prosthetics? Today, there are two widely used tooth replacement procedures: dental implants and bridgework. When a natural tooth can’t be saved — due to advanced decay, periodontal disease, or an accident like Duchovny’s — these methods offer good looking, fully functional replacements. So what’s the difference between the two? Essentially, it’s a matter of how the replacement teeth are supported.
With state-of-the-art dental implants, support for the replacement tooth (or teeth) comes from small titanium inserts, which are implanted directly into the bone of the jaw. In time these become fused with the bone itself, providing a solid anchorage. What’s more, they actually help prevent the bone loss that naturally occurs after tooth loss. The crowns — lifelike replacements for the visible part of the tooth — are securely attached to the implants via special connectors called abutments.
In traditional bridgework, the existing natural teeth on either side of a gap are used to support the replacement crowns that “bridge” the gap. Here’s how it works: A one-piece unit is custom-fabricated, consisting of prosthetic crowns to replace missing teeth, plus caps to cover the adjacent (abutment) teeth on each side. Those abutment teeth must be shaped so the caps can fit over them; this is done by carefully removing some of the outer tooth material. Then the whole bridge unit is securely cemented in place.
While both systems have been used successfully for decades, bridgework is now being gradually supplanted by implants. That’s because dental implants don’t have any negative impact on nearby healthy teeth, while bridgework requires that abutment teeth be shaped for crowns, and puts additional stresses on them. Dental implants also generally last far longer than bridges — the rest of your life, if given proper care. However, they are initially more expensive (though they may prove more economical in the long run), and not everyone is a candidate for the minor surgery they require.

When it comes to replacing a missing tooth, you have several options, including a removable partial denture or a fixed bridge. But the premier choice is “the new kid on the block” at just over thirty years old: dental implants. Implants are by far the most popular tooth replacement choice among both patients and dentists.
But they also happen to be the most expensive option, at least initially. So the question is, why invest in dental implants over less costly choices?
Here are 3 reasons why implants could be well worth their price.
More Like a real tooth than other restorations. Implants can match the life-like appearance of any other replacement choice, often utilizing the same types of materials. But where they really excel is in function—how they perform while biting and chewing. This is because the dental implant’s titanium post imbedded in the jawbone replaces the tooth root. No other dental restoration can do that—or perform better when comparing the resulting functionality.
Best long-term solution. As we mentioned before, the initial implant cost is typically higher than either dentures or bridges. But you should also consider their durability compared to other choices. It could be potentially much longer—possibly decades. This is because the titanium post creates an ultra-strong hold in the jawbone as bone cells naturally grow and adhere to this particular metal. The resulting hold can withstand the daily forces generated during eating and chewing. With proper care they might even last a lifetime, and actually cost you less in the long run over other choices.
Adaptable to other types of restoration. Implants have greater uses other than as individual tooth replacements. A few strategically placed implants can also be used to support removable dentures or a fixed bridge for multiple teeth or an entire dental arch. As the technology continues to advance, implants are helping to make other restoration options stronger, more stable and longer lasting—and adding more value to your investment.

For whatever reason, you’ve put off replacing a missing tooth for awhile. Now you want to fill that empty gap in your smile with a dental implant restoration.
But if your tooth’s been missing for a long time, there could be a problem with space. This is because the teeth on either side of the space may have gradually drifted into it, leaving no room for the implant. You could need orthodontic work first to return these teeth to their proper position.
We could use braces, metal orthodontic devices with wires threaded through brackets bonded to the teeth that are then anchored, usually to back teeth. The orthodontist uses elastics or springs as well as possibly incrementally tightening of the wire against the anchors. These techniques create pressure or tension on the teeth for the desired direction of movement. The teeth’s natural mechanism for movement does the rest.
But while effective, braces can be quite noticeable, an embarrassing thought for many adults having to wear them over several months of treatment. But there may be an alternative: clear aligners, a succession of slightly different plastic trays usually worn in two-week intervals. Sequentially wearing each tray gradually moves the teeth to their desired positions.
Though not appropriate for all bite situations, clear aligners have a number of benefits when they can be used. They’re nearly invisible to others and can be removed for hygiene tasks or rare special occasions. What’s more, the orthodontist may attach a temporary prosthetic (false) tooth to the trays to camouflage the missing space during treatment.
There’s one other issue you may have to deal with: if your tooth loss was related to periodontal (gum) disease, the gums and underlying bone may be in poor condition. In fact, substantial bone loss could rule out an implant altogether. But we may be able to remedy both gum and bone deficiencies through grafting or plastic surgery. It may be possible to regenerate enough bone to support the implant; and surgically repairing your gums will help ensure the implant appears natural.
If you have problems like these, don’t give up on your restoration goal just yet. With some orthodontic and dental work ahead of time, we may still be able to make implants a reality for you.
