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.

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.
Dental implants are best known as restorations for single missing teeth. But there’s more to them than that—they can also be used to support and secure removable dentures or fixed bridges.
That’s because a dental implant is actually a root replacement. A threaded titanium post is inserted directly into the jawbone where, over time, bone cells grow and adhere to it. This accumulated bone growth gives the implant its signature durability and contributes to its long-term success rate (95%-plus after ten years). It can support a single attached crown, or serve as an attachment point for a dental bridge or a connector for a removable denture.
The method and design of implants differentiates it from other restoration options. And there’s one other difference—implants require a minor surgical procedure to insert them into the jawbone.
While this might give you pause, implant surgery is no more complicated than a surgical tooth extraction. In most cases we can perform the procedure using local anesthesia (you’ll be awake the entire time) coupled with sedatives (if you have bouts of anxiety) to help you relax.
We first access the bone through small incisions in the gums and then create a small channel or hole in it. A surgical guide that fits over the teeth may be used to help pinpoint the exact location for the implant.
We then use a drilling sequence to progressively increase the size of the channel until it matches the implant size and shape. We’re then ready to insert the implant, which we remove at this time from its sterile packaging. We may then take a few x-rays to ensure the implant is in the right position, followed by closing the gums with sutures.
There may be a little discomfort for that day, but most patients can manage it with over-the-counter pain relievers like aspirin or ibuprofen. It’s what goes on over the next few weeks that’s of prime importance as the bone grows and adheres to the implant. Once they’re fully integrated, we’re ready to move to the next step of affixing your crown, bridge or denture to gain what you’ve waited so long for—your new implant-supported smile.

Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

Implant-supported fixed bridges are growing in popularity because they offer superior support to traditional bridges or dentures. They can also improve bone health thanks to the affinity between bone cells and the implants' titanium posts.
Even so, you'll still need to stay alert to the threat of periodontal (gum) disease. This bacterial infection usually triggered by dental plaque could ultimately infect the underlying bone and cause it to deteriorate. As a result the implants could loosen and cause you to lose your bridgework.
To avoid this you'll need to be as diligent with removing plaque from around your implants as you would with natural teeth. The best means for doing this is to floss around each implant post between the bridgework and the natural gums.
This type of flossing is quite different than with natural teeth where you work the floss in between each tooth. With your bridgework you'll need to thread the floss between it and the gums with the help of a floss threader, a small handheld device with a loop on one end and a stiff flat edge on the other.
To use it you'll first pull off about 18" of dental floss and thread it through the loop. You'll then gently work the sharper end between the gums and bridge from the cheek side toward the tongue. Once through to the tongue side, you'll hold one end of the floss and pull the floss threader away with the other until the floss is now underneath the bridge.
You'll then loop each end of the floss around your fingers on each hand and work the floss up and down the sides of the nearest tooth or implant. You'll then release one hand from the floss and pull the floss out from beneath the bridge. Rethread it in the threader and move to the next section of the bridge and clean those implants.
You can also use other methods like specialized floss with stiffened ends for threading, an oral irrigator (or "water flosser") that emits a pressurized spray of water to loosen plaque, or an interproximal brush that can reach into narrow spaces. If you choose an interproximal brush, however, be sure it's not made with metal wire, which can scratch the implant and create microscopic crevices for plaque.
Use the method you and your dentist think best to keep your implants plaque-free. Doing so will help reduce your risk of a gum infection that could endanger your implant-supported bridgework.
