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.
When dental implants hit the scene in the 1980s, they revolutionized the field of dental restorations. But as groundbreaking as they were then, they're even more advanced now.
Some of the advancements have to do with improvements in implant design and manufacturing. Implant sizes and shapes were once quite limited, but today they come in a variety of forms to better match the types of teeth they replace.
But there has also been important progress in complementary technologies that help us realize better outcomes. Many of these other advances have had a positive impact on the planning and surgical stages of implant installation.
CT/CBCT scanning. For the best outcome, it's critical to install an implant at the most appropriate location on the jaw. This can be difficult to determine, however, because of the location of oral and facial structures like nerves or sinuses that might interfere with implant placement. But using a type of computer tomography (CT) scanning called cone beam CT, we can produce a 3-D computer graphic image that helps us navigate possible obstructions as we pinpoint the ideal location for an implant.
Digital smile displays. We're now able to produce digital models of the mouth, which can assist with more than implant placement—we can also use them to visualize what a new smile with implants will look like before we install them. This is especially helpful in situations where only a few teeth need to be replaced: We want to ensure that the new implant crowns blend seamlessly with the remaining teeth for the most natural appearance.
Custom-made surgical guides. We've been using surgical guides to mark the exact drilling locations during implant surgery for many years. But 3-D printing technology can now help us produce surgical guides that are even more useful and precise. Using a 3-D printer, we can produce oral devices based on the patient's individual dental dimensions captured through digital scanning. That produces a better fit for the guide on the teeth and more accurate implant placement.
Together, these and other technological advances are helping us achieve even more successful results. Not only can they help us produce implant outcomes that can last for years or even decades, but also the most beautiful smiles possible.

Even in the 21st Century, losing most or all of your teeth is still an unfortunate possibility. Many in this circumstance turn to dentures, as their great-grandparents did, to restore their teeth. But today's dentures are much different from those of past generations—and dental implants are a big reason why.
The basic denture is made of a gum-colored, acrylic base with artificial teeth attached. The base is precisely made to fit snugly and comfortably on the patient's individual gum and jaw structure, as the bony ridges of the gums provide the overall support for the denture.
Implants improve on this through two possible approaches. A removable denture can be fitted with a metal frame that firmly connects with implants embedded in the jaw. Alternatively, a denture can be permanently attached to implants with screws. Each way has its pros and cons, but both have two decided advantages over traditional dentures.
First, because implants rather than the gums provide their main support, implant-denture hybrids are often more secure and comfortable than traditional dentures. As a result, patients may enjoy greater confidence while eating or speaking wearing an implant-based denture.
They may also improve bone health rather than diminish it like standard dentures. This is because the forces generated when chewing and eating travel from the teeth to the jawbone and stimulate new bone cell growth to replace older cells. We lose this stimulation when we lose teeth, leading to slower bone cell replacement and eventually less overall bone volume.
Traditional dentures not only don't restore this stimulation, they can also accelerate bone loss as they rub against the bony ridges of the gums. Implants, on the other hand, can help slow or stop bone loss. The titanium in the imbedded post attracts bone cells, which then grow and adhere to the implant surface. Over time, this can increase the amount of bone attachment and help stymie any further loss.
An implant-supported denture is more expensive than a standard denture, but far less than replacing each individual tooth with an implant. If you want the affordability of dentures with the added benefits of implants, this option may be worth your consideration.

Dental implants are popular with both patients and dentists for their durability and likeness to natural teeth. That natural look, though, can be difficult to attain, especially in what’s known as the “smile zone” — the area of the mouth where teeth are most visible when you smile.
Our biggest concern is the upper front teeth, where the gums are most visible, especially if you smile widely. It takes considerable skill, experience and artistry to position implants in this area so that they appear to naturally emerge from the gums and blend well with other teeth.
To obtain that natural look, we must first assess whether or not there’s enough bone present, which tends to dissolve (resorb) when a tooth is missing, to sufficiently anchor the implant in the right position. There also needs to be sufficient bone around adjacent teeth to support the tiny triangles of gum tissue between teeth called papillae. Without the papillae an unattractive black hole may result between the implant and an adjacent tooth or implant.
Another factor we must consider is the type of gum tissue you have. Everyone generally inherits one of two types of tissue from their parents: thin or thick. The type you have can influence the way the implant appears to emerge from the gums. If you have thick gums, they’re easier to work with and can cover more of the implant. Thinner tissues aren’t quite as easy and are less forgiving if an implant isn’t placed as precisely as possible.
In recent years, improvements in implant design have sought to provide greater stability around bone and gum tissues to offset some of the issues we’ve mentioned. A variation on the design of the top of the implant (where the crown is attached) changes the direction of growth for gum tissues from a horizontal orientation to a vertical one, which can help with the final appearance.
The first step, if you’re considering dental implants for a tooth in the smile zone, is to visit us for a complete examination to see if any of these factors may have an impact on your situation. We can then advise you on the best course of action to achieve the most attractive smile possible.

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.
