Among dental restorations, implants are the closest prosthetic we have to real teeth. They not only replace the visible crown, but the titanium post imbedded in the jawbone adequately substitutes for the tooth root. Because of their unique design, implants are not only life-like, they’re highly durable and could potentially last for decades.
But while their success rate is remarkably high (more than 95% exceed the ten-year mark), they can fail. Ironically, one possible cause for implant failure is periodontal (gum) disease. Although an implant’s materials are themselves impervious to disease, the tissues and underlying bone that support the implant aren’t. If these natural tissues become infected, the secure hold the implant has can weaken and fail.
A gum infection usually begins with dental plaque, a thin biofilm of bacteria and food particles that builds up on tooth surfaces. Certain strains of bacteria within plaque can infect the gums. One particular form of the disease known as peri-implantitis starts as an initial infection and ensuing inflammation of gum tissues around an implant. The disease can quickly spread down to the bone and destroy the integration between the bone and the implant that helps keep the implant in place.
That’s why it’s important for you to keep the implant and the tissues around it clean of plaque, just as you would the rest of your natural teeth. This requires daily brushing and flossing around the implant and other teeth, and visiting your dentist regularly for more thorough dental cleanings.
You should also be alert to any signs of disease, especially around implants: gum redness, swelling, bleeding or pus formation. Because of the rapidity with which peri-implantitis can spread, you should see your dentist as soon as possible if you notice any of these signs.
Preventing gum disease, and treating it promptly if it occurs, is a key part of implant longevity. Preserving your overall dental health will help make sure your implant doesn’t become a loss statistic.
Every year dentists place over 5 million dental implants for lost teeth, often removing the problem tooth and installing the implant at the same time. But getting a “tooth in a day” depends on a number of health factors, especially whether or not there’s adequate bone available for the implant. Otherwise, the implant’s placement accuracy and success could be compromised.
Bone loss can be a similar problem when a tooth has been missing for a long period of time. If this describes your situation, you may have already lost substantial bone in your jaw. To understand why, we need to know a little about bone’s growth cycle.
When bone cells reach the end of their useful life, they’re absorbed into the body by a process called resorption. New cells then form to take the older cells’ place in a continuous cycle that keeps the bone healthy and strong. Forces generated when we chew travel through the teeth to the bone and help stimulate this growth. But when a tooth is missing, the bone doesn’t receive this stimulus. As a result, the bone may not replace itself at a healthy rate and diminish over time.
In extreme cases, we may need to consider some other dental restoration other than an implant. But if the bone loss isn’t too severe, we may be able to help increase it through bone grafting. We insert safe bone grafting material prepared in a lab directly into the jaw through a minor surgical procedure. The graft then acts like a scaffold for bone cells to form and grow upon. In a few months enough new bone may have formed to support an implant.
Bone grafting can also be used if you’re having a tooth removed to preserve the bone even if you’re not yet ready to obtain an implant. By placing a bone graft immediately after extraction, it’s possible to retain the bone for up to ten years—enough time to decide on your options for permanent restoration.
Whatever your situation, it’s important that you visit us as soon as possible for a complete examination. Afterward we can assess your options and hopefully come up with a treatment strategy that will eventually include smile-transforming dental implants.
Losing a tooth from disease or accident can be traumatic. The good news, though, is that it can be replaced with a life-like replica that restores your smile. One of the most popular and durable solutions is a dental implant, which replaces not only the root of the tooth but the crown as well.
But there's a possible wrinkle with implants — for accurate placement there must be a sufficient amount of bone around it. This could be a problem if you've been missing the tooth for sometime: without the stimulus provided by a tooth as you chew, older bone cells aren't replaced at an adequate rate. The bone volume gradually diminishes, as up to 25% of its normal width can be lost during the first year after tooth loss. A traumatic injury can damage underlying bone to an even greater extent.
There is a possible solution, but it will require the services of other specialists, particularly a periodontist trained in gum and bone structure. The first step is a complete examination of the mouth to gauge the true extent of any bone loss. While x-rays play a crucial role, a CT scan in particular provides a three-dimensional view of the jaw and more detail on any bone loss.
With a more accurate bone loss picture, we can then set about actually creating new bone through grafting procedures. One such technique is called a ridge augmentation: after opening the gum tissues, we place the bone graft within a barrier membrane to protect it. Over time the bone will grow replacing both the grafting material and membrane structure.
Once we have enough regenerated bone, we can then perform dental implant surgery. There are two options: a “one-stage” procedure in which a temporary crown is placed on the implant immediately after surgery; or a “two-stage” in which we place the gum tissue over the implant to protect it as it heals and bone grows and attaches to it. In cases of pre-surgical bone grafting, it's usually best to go with the two-stage procedure for maximum protection while the bone strengthens around it.
Necessary preparation of the bone for a future dental implant takes time. But the extra effort will pay off with a new smile you'll be proud to display.
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.

Everyone has to face the music at some time — even John Lydon, former lead singer of The Sex Pistols, arguably England’s best known punk rock band. The 59-year old musician was once better known by his stage name, Johnny Rotten — a brash reference to the visibly degraded state of his teeth. But in the decades since his band broke up, Lydon’s lifelong deficiency in dental hygiene had begun to cause him serious problems.
In recent years, Lydon has had several dental surgeries — including one to resolve two serious abscesses in his mouth, which left him with stitches in his gums and a temporary speech impediment. Photos show that he also had missing teeth, which, sources say, he opted to replace with dental implants.
For Lydon (and many others in the same situation) that’s likely to be an excellent choice. Dental implants are the gold standard for tooth replacement today, for some very good reasons. The most natural-looking of all tooth replacements, implants also have a higher success rate than any other method: over 95 percent. They can be used to replace one tooth, several teeth, or an entire arch (top or bottom row) of teeth. And with only routine care, they can last for the rest of your life.
Like natural teeth, dental implants get support from the bone in your jaw. The implant itself — a screw-like titanium post — is inserted into the jaw in a minor surgical operation. The lifelike, visible part of the tooth — the crown — is attached to the implant by a sturdy connector called an abutment. In time, the titanium metal of the implant actually becomes fused with the living bone tissue. This not only provides a solid anchorage for the prosthetic, but it also prevents bone loss at the site of the missing tooth — which is something neither bridgework nor dentures can do.
It’s true that implants may have a higher initial cost than other tooth replacement methods; in the long run, however, they may prove more economical. Over time, the cost of repeated dental treatments and periodic replacement of shorter-lived tooth restorations (not to mention lost time and discomfort) can easily exceed the expense of implants.
That’s a lesson John Lydon has learned. “A lot of ill health came from neglecting my teeth,” he told a newspaper reporter. “I felt sick all the time, and I decided to do something about it… I’ve had all kinds of abscesses, jaw surgery. It costs money and is very painful. So Johnny says: ‘Get your brush!’”
We couldn’t agree more. But if brushing isn’t enough, it may be time to consider dental implants.
