Your teeth can take decades of daily biting and chewing and not miss a beat. But they do have a nemesis, dental disease, which can easily get the upper hand. As a result, millions of people lose teeth each year to tooth decay and periodontal (gum) disease.
But while both the living tissue that makes up teeth and gums are susceptible to bacterial attack, the non-living materials in a life-like dental implant are impervious to disease. That being the case, you would think your implants wouldn't need as much hygiene as your other teeth.
But they still do. True, implants in themselves aren't affected by infection, but the bone and other tissues that support them can become diseased. This often happens with advanced cases of gum disease.
There is, in fact, a particular form of gum infection associated with implants called peri-implantitis ("peri"—around; "it is"—inflammation), which occurs in the gums around an implant. Once it starts, peri-implantitis can advance at a rapid pace.
This is because implants don't have the gum attachment of real teeth, which can fight and slow the advance of a gum infection. Because an implant doesn't have this attachment, any infection around it continues virtually unimpeded. If the bone supporting an implant becomes infected, it can weaken to the point that the implant fails.
But this dire scenario can be avoided with continuing hygiene and maintenance of the gum tissues surrounding the implant. You should brush and floss every day around implants to remove dental plaque, the bacterial film most responsible for dental disease, just as you do with natural teeth.
It's also important to keep up regular dental visits for cleanings to remove lingering plaque and tartar (hardened plaque). Your dentist may also notice and clean away any residual cement from the restoration, which can also cause gum inflammation.
And, you should promptly see your dentist if you notice any telltale signs of a gum infection, such as swelling, redness or bleeding, especially around implants. The quicker we diagnose and treat a case of gum disease, particularly peri-implantitis, the less likely it will endanger your implant.
Ed Helms is best known for his role as the self-absorbed, Ivy League sales rep, Andy Bernard, on television's The Office. But to millions of fans he's also Stu, a member of a bachelor trip to Las Vegas in the 2009 movie The Hangover. In it, Stu and his friends wake up from a wild night on the Strip to find some things missing: the groom-to-be, their memories and, for Stu, a front tooth.
In reality, the missing tooth gag wasn't a Hollywood makeup or CGI (computer-generated imagery) trick—it was Ed Helm's actual missing tooth. According to Helms, the front tooth in question never developed and he had obtained a dental implant to replace it. He had the implant crown removed for the Hangover movie and then replaced after filming.
Helms' dental situation isn't that unusual. Although most of the 170 million-plus teeth missing from Americans' mouths are due to disease or trauma, a few happened because the teeth never formed. While most of these congenitally missing teeth are in the back of the mouth, a few, as in Helms' case, involve front teeth in the “smile zone,” which can profoundly affect appearance.
Fortunately, people missing undeveloped teeth have several good options to restore their smiles and dental function. The kind of tooth missing could help determine which option to use. For example, a bridge supported by the teeth on either side of the gap might work well if the teeth on either side are in need of crowns.
If the missing tooth happens to be one or both of the lateral incisors (on either side of the centermost teeth), it could be possible to move the canine teeth (the pointy ones, also called eye teeth) to fill the gap. This technique, known as canine substitution, may also require further modification—either by softening the canines' pointed tips, crowning them or applying veneers—to help the repositioned teeth look more natural.
The optimal solution, though, is to replace a missing tooth with a dental implant which then has a lifelike crown attached to it, as Ed Helms did to get his winning smile. Implant-supported replacement teeth are closest to natural teeth in terms of both appearance and function. Implants, though, shouldn't be placed until the jaw has fully developed, usually in early adulthood. A younger person may need a temporary restoration like a bonded bridge or a partial denture until they're ready for an implant.
Whatever the method, there's an effective way to restore missing teeth. Seeing us for an initial exam is the first step toward your own winning smile.
Even with modern prevention and treatment advances, losing teeth in later life is still a sad but common part of human experience. Just as generations have before, many today rely on dentures to regain their lost dental function and smile.
But although effective, dentures have their weaknesses. The most serious: they can't prevent jawbone deterioration, a common problem associated with tooth loss.
Bone health depends on chewing forces applied to the teeth to stimulate replacement growth for older bone cells. When teeth are gone, so is this stimulation. Dentures can't replicate the stimulus and may even accelerate bone loss because they can irritate the bone under the gums as they rest upon them for support.
But there's a recent advance in denture technology that may help slow or even stop potential bone loss. The advance incorporates implants with dentures to create two hybrid alternatives that may be more secure and healthier for the supporting bone.
The first is known as an overdenture, a removable appliance similar to a traditional denture. But instead of deriving its support from the gums alone, the overdenture attaches to three to four implants (or only two, if on the lower jaw) that have been permanently set into the jawbone. This not only increases stability, but the implants made of bone-friendly titanium attract and foster increased bone growth around them. This can help slow or even stop the cycle of bone loss with missing teeth.
The second type is a fixed denture. In this version, four to six implants are implanted around the jaw arch. The denture is then secured in place to these implants with screws. It's a little more secure than the overdenture, but it's also more expensive and requires good quality bone at the implant sites.
If you've already experienced significant bone loss you may first need bone grafting to build up the implant sites for these options, or choose traditional dentures instead. But if you're a good candidate for an implant-supported denture, you may find it provides better support and less risk of continuing bone loss than traditional dentures.

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.
