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.

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.
One of the best and most successful tooth replacement choices available is the dental implant. No other restorative method is as similar in both form and function to a real tooth as an implant; and with a success rate of 95-plus percent after ten years, it’s one of the most durable.
But there can be extenuating circumstances that make obtaining an implant difficult or sometimes impossible. One possible problematic situation is the systemic disease diabetes.
Diabetes is a hormonal condition in which the body is unable to sufficiently regulate the amount of glucose (a basic sugar that provides energy to the body’s cells) within the blood stream. Normally, the pancreas produces the hormone insulin to reduce excess glucose. But diabetes interferes with this insulin production: if you have Type 1 diabetes, the pancreas has stopped producing insulin altogether; if you have the more common Type 2, the body doesn’t produce adequate insulin or it doesn’t respond sufficiently to the insulin produced.
Over time diabetes can affect other areas of health, especially wound healing. Because the condition gradually causes blood vessels to narrow and stiffen, the normal inflammatory response to disease or trauma can become prolonged. This in turn slows the rate of wound healing.
Slow wound healing can have a bearing on the recovery period just after implant surgery, especially the necessary integration process that takes place between the bone and the titanium metal implant that provides its signature strength. If that process is impeded by slow wound healing caused by diabetes, the risk increases dramatically for implant failure.
That’s the worst case scenario if you have diabetes, but only if your condition is out of control. If, however, you have your blood sugar levels well regulated through medication, diet and exercise, then your chances for implant success could easily be on par with someone without diabetes.
So if you’re diabetic and are considering dental implants for missing teeth, it’s important to discuss the possibility of obtaining them with both your dentist and the physician caring for your diabetes. With your overall healthcare team working together, there’s no reason why diabetes should stop you from enjoying this premiere restoration for missing teeth.

Probably a day doesn’t go by that you don’t encounter advertising for dental implants. And for good reason: implants have taken the world of dentistry by storm.
Since their inception over thirty years ago, implants have rocketed ahead of more conventional tooth replacements to become the premier choice among both dentists and patients. But what is an implant—and why are these state-of-the-art dental devices so popular?
Resemblance to natural teeth. More than any other type of dental restoration, dental implants mimic both the appearance and function of natural teeth. Just as teeth have two main parts—the roots beneath the gum surface and the visible crown—so implants have a similar construction. At their heart, implants are root replacements by way of a titanium metal post imbedded in the jawbone. To this we can permanently attach a life-like porcelain crown or even another form of restoration (more about that in a moment).
Durability. Implant materials and unique design foster a long-term success rate after ten years in the 95-plus percentile. They achieve this longevity primarily due to the use of titanium as the primary metal in the implant post. Because bone has an affinity for titanium, it will grow and adhere to the post over time to create a well-anchored hold. With proper maintenance and care implants can last for decades, making them a wise, cost-effective investment.
Added stability for other restorations. While most people associate implants with single tooth replacements, the technology has a much broader reach. For example, just a few strategically-placed implants can support a removable denture, giving this traditional restoration much more security and stability. What’s more, it can help stop bone loss, one of the main drawbacks of conventional dentures. In like fashion, implants can support a fixed bridge, eliminating the need to permanently alter adjacent teeth often used to support a conventional bridge.
With continuing advances, implant technology is becoming increasingly useful for a variety of restorative situations. Depending on your individual tooth-loss situation, dental implants could put the form and function back in your smile for many years to come.

For generations, dentures have helped people avoid the dire consequences of total teeth loss. Now, implant technology is making them even better.
Composed of life-like prosthetic teeth fixed within a plastic or resin gum-colored base, dentures are manufactured to fit an individual patient’s mouth for maximum fit, comfort and performance. But dentures also have a critical drawback—they can’t stop bone loss in the jaw.
Bone is constantly regenerating as older cells dissolve and then are replaced by newer cells. In the jawbone, the forces generated when we chew travel through the teeth to the bone and help stimulate this new cell growth. When teeth are missing, though, the bone doesn’t receive this stimulus and may not regenerate at a healthy rate, resulting in gradual bone loss.
Dentures can’t transmit this chewing stimulus to the bone. In fact, the pressure they produce as they rest on top of the gums may actually accelerate bone loss. Over time then, a denture’s once secure and comfortable fit becomes loose.
In the past, most patients with loose dentures have had them relined with new dental material to improve fit, or have new dentures created to conform to the changed contours of the jaws. But implant technology now offers another alternative.
Implants are in essence a tooth root replacement. Dentists surgically implant a titanium metal post directly into the jawbone that naturally attracts bone cells to grow and adhere to it over time (a process called osseointegration). This not only creates a secure and lasting hold, it can also stop or even reverse bone loss.
Most people know implants as single tooth replacements with a porcelain crown attached to the titanium post. But a few strategically placed implants can also support either removable or fixed dentures. Removable dentures (also called overdentures) usually need only 3 or 4 implants on the top jaw and 2 on the bottom jaw for support through built-in connectors in the dentures that attach to the implants. A fixed bridge may require 4-6 implants to which they are permanently attached.
There are pros and cons for each of these options and they’re both more expensive than traditional dentures. In the long run, though, implant-supported dentures could be more beneficial for your bone health and hold their fit longer.
