Due to financial circumstances, people often have a lost tooth restored with a removable partial denture, an effective appliance that restores function and a degree of aesthetic appearance. Later, though, they may want to improve both function and appearance with a dental implant.
If this describes you, you’re making a great choice. Dental implants are the closest technology we have to a natural tooth. But there may be a roadblock to your implant, especially if a long time has passed since your tooth loss—there may not be enough bone at the site to place an implant.
The heart of an implant is a titanium metal post surgically imbedded in the jawbone. The titanium naturally attracts bone cells, which grow and adhere to it to form a solid hold that can support a porcelain crown or other restorations like bridges or dentures. But to achieve a natural appearance it’s important that the implant is placed in the right location. To achieve that requires adequate bone.
But there may not be adequate bone if the tooth has been missing for a while. The forces generated when we chew travel through the teeth to the jawbone, which stimulates bone growth. If that stimulus is absent because of a missing tooth, new bone cells may not replace older ones at a healthy rate and the total bone volume begins to diminish. A denture can’t compensate and, in fact, accelerates bone loss.
But there may be a solution: bone grafting. With this procedure we place a donor bone graft into the area of bone deficiency some time before implant surgery. The graft serves as a scaffold for new bone cells to grow upon. Hopefully, this will produce enough healthy bone to support an implant. If the bone deficiency is minor, we may place the implant and the bone graft at the same time.
If you have experienced bone loss, we must first determine the amount of bone at the missing tooth site and whether grafting is a viable option. Bone grafting postpones your implant, but the delay will be worth the wait if we’re successful. With increased bone volume you’ll be able to obtain a new tooth that’s superior to your current restoration.
There’s a lot to like about dental implants for replacing missing teeth. Not only are they life-like, but because they replace the root they also function much like a natural tooth. They also have another unique benefit: a track record for long-lasting durability. It’s estimated more than 95% of implants survive at least ten years, with a potential longevity of more than 40 years.
But even with this impressive record, we should still look at the few that didn’t and determine the reasons why they failed. We’ll soon find that a great number of those reasons will have to do with both oral and general health.
For example, implants rely on adequate bone structure for support. Over time bone cells grow and adhere to the implant’s titanium surface to create the durable hold responsible for their longevity. But if conditions like periodontal (gum) disease have damaged the bone, there might not be enough to support an implant.
We may be able to address this inadequacy at the outset with a bone graft to encourage growth, gaining enough perhaps to eventually support an implant. But if bone loss is too extensive, it may be necessary to opt for a different type of restoration.
Slower healing conditions caused by diseases like diabetes, osteoporosis or compromised immune systems can also impact implant success. If healing is impeded after placement surgery the implant may not integrate well with the bone. An infection that existed before surgery or resulted afterward could also have much the same effect.
Oral diseases, especially gum disease, can contribute to later implant failures. Although the implant’s materials won’t be affected by the infection, the surrounding gum tissues and bone can. An infection can quickly develop into a condition known as peri-implantitis that can weaken these supporting structures and cause the implant to loosen and give way. That’s why prompt treatment of gum disease is vital for an affected implant.
The bottom line: maintaining good oral and general health, or improving it, can help keep your implant out of the failure column. Perform daily brushing and flossing (even after you receive your implant) and see your dentist regularly to help stop dental disease. Don’t delay treatment for gum disease or other dental conditions. And seek medical care to bring any systemic diseases like diabetes under control.

Seven out of ten Americans are missing at least one tooth due to decay, periodontal (gum) disease or injury. Unfortunately, the consequences go far beyond a missing tooth — the loss of even one could set in motion a cascade of problems.
Perhaps the most damaging of these problems is bone loss. Like other living tissue, bone has a life cycle — older cells dissolve (resorb) into the body and are replaced by fresher cells. This growth cycle in the jawbone receives stimulation from forces generated by teeth when we chew or bite. If a tooth is no longer present to provide this stimulation, the affected bone cells won’t regenerate at a healthy rate. Over time this causes the volume of bone to diminish, as much as 25% the first year after tooth loss.
The void left by a missing tooth can also adversely affect remaining teeth. Teeth are held in place by a tough but elastic tissue known as the periodontal ligament that lies between the tooth and the bone. The ligament enables teeth to move gradually in response to mouth changes so that the teeth remain tightly aligned with each other. When there’s a gap from a missing tooth, this tendency will cause the teeth on either side to move (or “drift”) toward the open space. Although a natural phenomena, it can result in a malocclusion (poor bite).
That’s why it’s important to replace a missing tooth with a life-like replica — not just for appearance’s sake, but also to improve function and prevent the rise of these other problems. While many options exist (from removable dentures to fixed bridges) the choice most preferred by dentists and patients is the dental implant.
An implant replaces the tooth root as well as the crown, because it’s imbedded securely into the jawbone. Because of a natural affinity with titanium, the principal metal used in implants, bone cells will grow to its surface. Not only will this anchor the implant more securely, it will slow or even stop bone loss.
If you have a missing tooth, you should visit us as soon as possible to consider your options for a replacement. A new tooth will help stop even greater problems from occurring.

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.

Let’s say you’re traveling to Italy to surprise your girlfriend, who is competing in an alpine ski race… and when you lower the scarf that’s covering your face, you reveal to the assembled paparazzi that one of your front teeth is missing. What will you do about this dental dilemma?
Sound far-fetched? It recently happened to one of the most recognized figures in sports — Tiger Woods. There’s still some uncertainty about exactly how this tooth was taken out: Was it a collision with a cameraman, as Woods’ agent reported… or did Woods already have some problems with the tooth, as others have speculated? We still don’t know for sure, but the big question is: What happens next?
Fortunately, contemporary dentistry offers several good solutions for the problem of missing teeth. Which one is best? It depends on each individual’s particular situation.
Let’s say that the visible part of the tooth (the crown) has been damaged by a dental trauma (such as a collision or a blow to the face), but the tooth still has healthy roots. In this case, it’s often possible to keep the roots and replace the tooth above the gum line with a crown restoration (also called a cap). Crowns are generally made to order in a dental lab, and are placed on a prepared tooth in a procedure that requires two office visits: one to prepare the tooth for restoration and to make a model of the mouth and the second to place the custom-manufactured crown and complete the restoration. However, in some cases, crowns can be made on special machinery right in the dental office, and placed during the same visit.
But what happens if the root isn’t viable — for example, if the tooth is deeply fractured, or completely knocked out and unable to be successfully re-implanted?
In that case, a dental implant is probably the best option for tooth replacement. An implant consists of a screw-like post of titanium metal that is inserted into the jawbone during a minor surgical procedure. Titanium has a unique property: It can fuse with living bone tissue, allowing it to act as a secure anchor for the replacement tooth system. The crown of the implant is similar to the one mentioned above, except that it’s made to attach to the titanium implant instead of the natural tooth.
Dental implants look, function and “feel” just like natural teeth — and with proper care, they can last a lifetime. Although they may be initially expensive, their quality and longevity makes them a good value over the long term. A less-costly alternative is traditional bridgework — but this method requires some dental work on the adjacent, healthy teeth; plus, it isn’t expected to last as long as an implant, and it may make the teeth more prone to problems down the road.
What will the acclaimed golfer do? No doubt Tiger’s dentist will help him make the right tooth-replacement decision.
