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.

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.

Losing teeth to tooth decay or periodontal (gum) disease is never easy. But with implant-supported bridgework, you can regain lost function and appearance with a restoration that could last for many years.
Don’t think, though, that dental disease woes are a thing of the past with your new implants. Although your restoration itself can’t be infected, the supporting gums and underlying bone can, often through bacterial plaque accumulating around the implants. The bone that supports the implants could deteriorate, dramatically increasing your chances of losing your restoration.
It’s essential, then, that you keep the area between the bridge and gums clean of plaque through daily hygiene. This definitely includes flossing around the implants.
Flossing with an implant-supported bridge will be different than with natural teeth: instead of flossing between teeth you’ll need to thread the floss between the bridge and gums. Although this is a bit more difficult, it can be done with the help of a floss threader, a device with a loop on one end and a long, thin plastic point on the other—similar to a sewing needle.
To use it, thread about 18” of floss through the loop and then pass the threader’s thin end first through the space between the bridge and gums toward the tongue until the floss threader pulls through. You can then take hold of one end of the floss and then pull the threader completely out from beneath the bridge. Then, you wrap the ends around your fingers as you would normally and thoroughly floss the implant surfaces you’re accessing. You then release one end of the floss, pull out the remainder, rethread it in the threader and repeat the process in the next space between implants.
You also have other hygiene tool options: prefabricated floss with stiffened ends that thread through the bridge-gum space that you can use very easily; or you can purchase an interproximal brush that resembles a pipe cleaner with thin plastic bristles to access the space and brush around the implants.
Some patients also find an oral irrigator, a handheld device that sprays a pressurized stream of water to loosen and flush away plaque, to be an effective way of keeping this important area clean. But that said, oral irrigators generally aren’t as effective removing dental plaque as are floss or interproximal brushes.
Whatever flossing method you choose, the important thing is to choose one and practice it every day. By keeping bacterial plaque from building up around your implants, you’ll help ensure you won’t lose your restoration to disease, so it can continue to serve you for many years to come.
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.

Not long ago, the most affordable option for total tooth loss was a removable denture. Dentures, prosthetic (false) teeth set in gum-colored acrylic plastic bases, can effectively restore function and appearance. But the appliance continues to have one major drawback: it can accelerate bone loss in the jaw.
Like other living tissues, older bone cells die and become absorbed into the body (resorption). Normally they're replaced by newer cells. The forces generated when we chew our food travel through the teeth to stimulate this new growth. This stimulus ends when we lose our teeth, and so cell replacement can slow to an abnormal rate. Eventually, this causes bone loss.
Removable dentures can't provide this stimulation. In fact, the pressure generated as they compress the gums' bony ridges can even accelerate bone loss. That's why over time a denture's fit can become loose and uncomfortable — the bone has shrunk and no longer matches the contours of the dentures.
In recent years, though, a new development has been able to provide greater support to dentures while at the same time slowing or even stopping bone loss. We can now support dentures with dental implants.
Implants are best known as individual tooth replacements: a titanium metal post replaces the root, while a life-like porcelain crown attaches to the post to replace the visible tooth. In addition to providing a longer-lasting alternative to removable dentures, implants provide a very important health benefit: they improve bone density because they mimic the function of natural teeth. Bone cells are naturally attracted to the titanium; they adhere to the titanium post and are stimulated to grow through the action of chewing, increasing bone density and securing the implant's hold in the jaw.
Using the same technology we can support removable dentures, or even full fixed bridges. Rather than rest directly on the bony ridges, a denture can make a secure connection through a coupling system with just a few strategically placed implants. We can also permanently attach a full bridge by fastening it to a few implants with screws.
Not only do we eliminate the pressure from dentures compressing the gums and bone tissue, we can actually stimulate bone growth with the implants. Although more costly upfront than traditional dentures, unlike traditional dentures which must be replaced every five to seven years, long-lasting implants may be more cost-effective over the long-run.
