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.

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.
It's a common practice among people slowly losing their teeth to have their remaining teeth removed. They find dentures to be less costly than replacing one tooth at a time or caring for those that remain. On the other hand, it's usually healthier for the mouth to preserve remaining teeth as long as possible, replacing them only as necessary.
This latter strategy has up to now been difficult and expensive to achieve. But dental implants are changing that—using these imbedded titanium metal devices with a variety of restorations, we're able to better plan and implement staged tooth replacement.
Most people associate implants with single tooth replacements of a life-like crown cemented or screwed into an abutment attached to the implant post. This can play an early role in a staged replacement plan, but at some point, multiple single-tooth implants can become quite expensive.
Implants, however, have a much broader range of use. A few strategically placed implants can support a variety of restorations, including bridges and removable or fixed dentures. Four to eight implants, for example, can secure a fixed denture replacing all teeth on a jaw, far fewer than the number needed to replace the teeth individually.
Implants may also improve the function of traditional restorations. For instance, dentures can't stop the bone loss that often results from tooth loss—in fact, they will accelerate it as they rub and irritate the bony ridges of the jaw. By contrast, implants stimulate bone growth, slowing or even stopping the process of bone loss.
In a traditional bridge, the outer crowns of the restoration are bonded to the teeth on either side of the missing tooth gap (the middle crowns fill the gap). These support teeth must be permanently altered to accommodate the crowns. But an implant-supported bridge doesn't depend on other teeth for support, thus eliminating the need to permanently alter any teeth.
More importantly, previously placed implants often become part of the next stages of tooth replacement, like building on an addition onto an existing house. All in all, including implants in your ongoing dental restoration can help you enjoy the benefits of preserving your natural teeth for much longer.

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.
