Losing all your teeth can dramatically impact your life for the worst. Fortunately, we can give you your "teeth" back. The most common way, at least until a few decades ago, is with custom dentures, which reasonably restore life-like appearance and dental function. But it does have one major drawback—it can't stop bone loss.
Loss of bone in the jaws often occurs with missing teeth. Normally, the bone continuously generates newer cells to replace older ones that have died. Chewing stimulates this growth as the force generated travels up through the teeth to the bone. But when teeth go missing, new bone growth slows, eventually causing the bone's volume and density to decrease.
Dentures can't reactivate this lost stimulation, and so bone loss may continue. Dentures even accelerate this loss as the compressive forces applied to the bony ridge are detrimental. This often leads to a "loosening" of a denture's fit that can make them uncomfortable and less secure to wear.
Today, however, patients with total tooth loss have another option that could alleviate the problem of bone loss—dental implants. Since their inception forty years ago, implants have become the preferred method of both dentists and patients for tooth replacement.
Implants consist of a titanium metal post that's surgically imbedded into the jawbone. Bone cells are attracted to this particular metal, readily multiplying and adhering to the implant's titanium surface. Because of this, an implant can slow or even stop bone loss.
Most people are familiar with the single tooth implant with an attached lifelike crown. Although this use of implants could be used to restore total tooth loss, it can be quite costly replacing over two dozen teeth individually.
But implants could still be part of the answer for someone with complete tooth loss, because they can also be used to support traditional restorations. A few implants strategically placed around the jaw can support either a removable denture or a fixed bridge.
Besides being a cost-effective way to add support to these traditional tooth replacements, the inclusion of implants will likely decrease continuing bone loss. Most importantly, it can give you back your dental function—and your smile to boot.

Around one in ten U.S. adults have diabetes, a metabolic disease that can disrupt other aspects of a person's health like wound healing and vision. It could also cause complications with dental implants, the premier replacement choice for missing teeth.
There are two basic types of diabetes. In type 1 diabetes, the pancreas stops producing insulin, a hormone needed to regulate the amount of sugar glucose in the bloodstream. With the more prevalent type 2 diabetes, the body either doesn't produce enough insulin or doesn't respond efficiently to the insulin produced.
Uncontrolled diabetes can contribute to several dangerous health conditions. In addition to vision impairment and poor wound healing, diabetics are at higher risk for other problems like kidney disease or nerve damage. Drastic swings in blood glucose levels can also cause coma or death.
Many diabetics, though, are able to manage their condition through diet, exercise, medications and regular medical care. Even so, they may still encounter problems with wound healing, which could complicate getting a dental implant.
An implant is composed of a titanium metal post imbedded into the jawbone. Because of its affinity with titanium, bone cells naturally grow and adhere to the implant's metal surface. Several weeks after implant surgery, enough bone growth occurs to fully secure the implant within the jaw.
But this integration process may be slower for diabetics because of sluggish wound healing. It's possible for integration to not fully occur in diabetic patients after implant surgery, increasing the risk of eventually losing the implant.
Fortunately, though, evidence indicates this not to be as great a concern as once thought. A number of recent group studies comparing diabetic and non-diabetic implant patients found little difference in outcomes—both groups had similar success rates (more than 95 percent).
The only exception, though, were diabetic patients with poor glucose control, who had much slower bone integration that posed a threat to a successful implant outcome. If you're in this situation, it's better if you're first able to better control your blood glucose levels before you undergo surgery.
So, while diabetes is something to factor into your implant decision, your chances remain good for a successful outcome. Just be sure you're doing everything you can to effectively manage your diabetes.

Losing teeth can make it more difficult to eat, not to mention the effect it can have on your smile. But that could be just the beginning of your problems. Missing teeth can contribute to extensive bone loss within your jaws and face. Here's why.
Bone is like any other living tissue—cells develop, function and eventually die, and new cells take their place. Forces generated during chewing stimulate this new growth, helping the jawbone maintain its normal volume and density.
But you lose this stimulus when you lose teeth. This can cause a slowdown in bone cell regrowth that can eventually diminish bone volume. And it can happen relatively quickly: you could lose a quarter or more of jawbone width around a missing tooth within a year.
As this loss continues, especially in cases of multiple missing teeth, the bone can eventually erode to its base level. This loss of dental function can make chewing more difficult, place more pressure on the remaining teeth and adversely affect facial appearance. It could also prevent an implant restoration to replace missing teeth.
Dentures and other forms of dental restoration can replace missing teeth, but not the chewing stimulus. Dentures in particular will accelerate bone loss, because they can irritate the bony gum ridges they rest upon.
Dental implants, on the other hand, can slow or even stop bone loss. Implants consist of a metal post, typically made of titanium, imbedded into the jawbone at the site of the missing tooth with a life-like crown attached. Titanium also has a strong affinity with bone so that bone cells naturally grow and adhere to the implant's surface. This can produce enough growth to slow, stop or even reverse bone loss.
This effect may also work when implants are combined with other restorations, including dentures. These enhanced dentures no longer rest on the gums, but connect to implants. This adds support and takes the pressure off of the bony ridge, as well as contributes to better bone health.
If you've lost a tooth, it's important to either replace it promptly or have a bone graft installed to help forestall any bone loss in the interim. And when it's time to replace those missing teeth, dental implants could provide you not only a life-like solution, but a way to protect your bone health.

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.

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.
