Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.
Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.
While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.
But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.
Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.
There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.
The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.
While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.

People are choosing dental implants at an increasing rate to replace missing teeth, either as an individual tooth or as a support for other restorations. But unlike other replacement options, we must surgically install the titanium post at the heart of the system directly into the jawbone.
While the term “surgery” might make you nervous, there's nothing at all to worry about. Here's what you need to know about before, during and after this relatively minor procedure.
Before. While the actual procedure is no more complicated than a tooth extraction, it ultimately depends on careful planning beforehand. Using x-ray diagnostics, we prepare a precise surgical guide to help us locate the best position to place them for a successful outcome. We'll also need to check bone volume to make sure there's an adequate amount to securely anchor the implant. If the bone is insufficient you may need bone grafting to build up the site or another replacement option.
During. The actual procedure begins, of course, with local anesthesia to numb the site — you should feel no pain and very minimal discomfort. We access the bone through the gums; often using a surgical guide for alignment, we create a small channel or hole with a sequence of drills that gradually increase the size until it can accommodate the implant. We remove the implants from their sterile packaging and install them immediately into the channel. After confirming their proper positioning with x-rays, we can close the gum tissues over it for protection during healing or attach a healing abutment that extends through the gum tissue thereby avoiding a second surgical procedure.
After. Because we disrupt relatively little of the soft tissue and bone, there's only minimal discomfort afterward easily managed with aspirin, ibuprofen or similar anti-inflammatory medication. We may also prescribe antibiotics to guard against infection while the gums heal. During the next several weeks, the titanium post, which has an affinity to bone, will become more secure as bone cells grow and adhere to it. It's also during this time that a dental lab creates your permanent crown or other restoration that matches the color and tooth shape so it will blend with your other teeth.
This process is complete when we install the final restoration onto the implant. You'll have a new smile and better function.

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.

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.

What's so special about dental implants — and why should you consider one to replace a missing tooth?
Although they've only been widely available for thirty years, dental implants have climbed to the top of tooth replacement choices as the premier restorative option. Since their debut in the 1980s, dentists have placed over 3 million implants.
There's one overriding reason for this popularity: in structure and form, dental implants are the closest replacement we have to a natural tooth. In fact, more than anything else an implant is a root replacement, the part of the tooth you don't see.
The artificial root is a titanium post surgically imbedded into the jaw bone. Later we can attach a porcelain crown to it that looks just like a visible tooth. This breakthrough design enables implants to handle the normal biting forces generated in the mouth for many years.
There's also an advantage in using titanium dental implants. Because bone cells have a special affinity to the metal, they will grow and attach to the implant over time. Not only does this strengthen the implant's hold within the jaw, the added growth also helps deter bone loss, a common problem with missing teeth.
It's this blend of strength and durability that gives implants the highest success rate for any tooth replacement option. Over 95% of implants placed attain the 10-year mark, and most will last for decades.
Dental implant treatment, however, may not be possible in every situation, particularly where significant bone loss has occurred. They're also relatively expensive, although more cost-effective than other options over the long term.
Even so, implants can play an effective and varied role in a dental restoration. While single implants with attached crowns are the most common type of replacement, they can also play a supporting role with other restorative options. As few as two strategically placed implants can provide a more secure connection for removable dentures or fixed bridges.
You'll need to first undergo a thorough dental examination to see if implants could work for you. From there, we'll be happy to discuss your options for using this "best of the best" restoration to achieve a new, beautiful smile.
