People have depended on dentures for generations—and they still do. That's because they work, both in restoring dental function and a smile marred by missing teeth.
But they have one major drawback related to bone health. That's because living bone has a life cycle: as older cells die, new ones form to take their place. The pressure generated when we chew stimulates this growth. But when this stimulus goes missing along with the teeth, the cell replacement rate slows and bone volume and density gradually diminishes.
Traditional dentures can't transmit this chewing pressure stimulus. And because they rest directly on the gum ridges, they can adversely affect the underlying bone and actually accelerate bone loss.
But implant technology potentially solves this bone loss problem with dentures by using implants rather than the gums to support them. It's a two-fold benefit: first, the implants relieve much of the irritation to the gums and bone caused by traditional dentures. Primarily, though, the implants themselves can slow or even stop continuing bone loss.
Most implants are made of titanium, not only because it's compatible with the body, but also because it has an affinity with bone. Over time bone cells grow on the titanium post imbedded in the jawbone. This process not only creates stability and durability, it can improve bone health.
In recent years dentists have incorporated implants with dentures to create two exciting treatment options. With one option, the dentist installs two or more implants in the jaw, to which a specially fitted removable denture can be attached. You would still have the ease of removing the denture for cleaning, while gaining greater stability and a reduced risk of bone loss.
The other option is a fixed denture (or bridge) attached permanently to implants. For this option, a patient's jawbone must be adequate and healthy enough to support at least four to six implants. A fixed denture is also often costlier and more complex than a removable denture, but it can feel more like real teeth. It also promotes better bone health too.
Although both options are more expensive than traditional dentures, they can pay dividends for long-term dental health. Implants could help you enjoy your new dentures and resulting smile for a long time to come.

Many people with diabetes are hesitant about getting dental implants because they’re under the impression their chances of failure are greater than for non-diabetics. But if you’re one of the 26 million Americans with diabetes, that isn’t necessarily so — with a little extra precaution before, during and after implant surgery.
Diabetes is a group of diseases that affect how the body processes glucose. This simple sugar is used by the body to provide energy to cells, but can also cause damage if its volume level in the bloodstream is too high. The body normally regulates this through the hormone insulin produced by the pancreas.
The pancreas in people with Type 1 diabetes doesn’t produce insulin and so they must receive an outside source of the hormone through daily injections with careful daily monitoring of glucose levels. Those with Type 2 diabetes, the most common form of the disease, don’t produce a sufficient amount of insulin or the body no longer responds to the insulin produced. For either type, abnormal glucose levels — either too high or too low — can have adverse affects on the body, including blindness, nerve damage, gangrene, coma or death.
Diabetes can also slow wound healing, increase the risk of infection, and alter the body’s inflammatory response, all of which are major concerns when placing implants. Because implant placement involves minor surgery in which a wound results, there’s been wide concern that a slower healing process could increase the risk of implant failure.
Recent studies, though, are encouraging especially for patients who have their diabetes under control through medication, diet and exercise. Patients with poor glucose control are at higher risk, because it can take longer for the bone to heal around an implant after placement. For such individuals special considerations to guard against infection may be needed during implant surgery.
In fact, the implant success rate for most diabetics is about the same as for non-diabetic patients, 95%. With proper disease management and a little extra wound care, you can be among the many that experience a favorable outcome and a more attractive smile with dental implants.
In real life he was a hard-charging basketball player through high school and college. In TV and the movies, he has gone head-to-head with serial killers, assorted bad guys… even mysterious paranormal forces. So would you believe that David Duchovny, who played Agent Fox Mulder in The X-Files and starred in countless other large and small-screen productions, lost his front teeth… in an elevator accident?
“I was running for the elevator at my high school when the door shut on my arm,” he explained. “The next thing I knew, I was waking up in the hospital. I had fainted, fallen on my face, and knocked out my two front teeth.” Looking at Duchovny now, you’d never know his front teeth weren’t natural. But that’s not “movie magic” — it’s the art and science of modern dentistry.
How do dentists go about replacing lost teeth with natural-looking prosthetics? Today, there are two widely used tooth replacement procedures: dental implants and bridgework. When a natural tooth can’t be saved — due to advanced decay, periodontal disease, or an accident like Duchovny’s — these methods offer good looking, fully functional replacements. So what’s the difference between the two? Essentially, it’s a matter of how the replacement teeth are supported.
With state-of-the-art dental implants, support for the replacement tooth (or teeth) comes from small titanium inserts, which are implanted directly into the bone of the jaw. In time these become fused with the bone itself, providing a solid anchorage. What’s more, they actually help prevent the bone loss that naturally occurs after tooth loss. The crowns — lifelike replacements for the visible part of the tooth — are securely attached to the implants via special connectors called abutments.
In traditional bridgework, the existing natural teeth on either side of a gap are used to support the replacement crowns that “bridge” the gap. Here’s how it works: A one-piece unit is custom-fabricated, consisting of prosthetic crowns to replace missing teeth, plus caps to cover the adjacent (abutment) teeth on each side. Those abutment teeth must be shaped so the caps can fit over them; this is done by carefully removing some of the outer tooth material. Then the whole bridge unit is securely cemented in place.
While both systems have been used successfully for decades, bridgework is now being gradually supplanted by implants. That’s because dental implants don’t have any negative impact on nearby healthy teeth, while bridgework requires that abutment teeth be shaped for crowns, and puts additional stresses on them. Dental implants also generally last far longer than bridges — the rest of your life, if given proper care. However, they are initially more expensive (though they may prove more economical in the long run), and not everyone is a candidate for the minor surgery they require.

You’ve probably heard a lot about dental implants as replacements for missing teeth. So, why are they so popular with both patients and dentists? While other restorations can mimic the color, shape and texture of natural teeth, dental implants have one clear advantage — and it’s all about the bone.
The bone in your jaws provides stability and structure for teeth — without it and the intricate system of gum tissue attachments teeth couldn’t survive the normal biting and chewing forces they encounter every day. That’s why bone health is crucial for maintaining tooth integrity.
Teeth also help bone to remain strong and healthy. The forces we generate as we chew transmit through the tooth roots to the bone, which stimulates continuing growth. If a tooth is missing, however, the bone around it doesn’t receive this stimulation and may begin to lose some of its volume and density — up to a quarter of its width in just the first year after tooth loss.
This bone loss continues even with other restorations because they’re not able to stimulate bone growth. But dental implants can. This is because the portion of the implant imbedded into the bone is constructed most often of titanium, which has a natural affinity toward bone. Bone cells are naturally attracted to titanium and will begin to grow and attach to the metal surface, a process known as osseointegration.
Through osseointegration, the implant develops a durable bond with the jawbone a few weeks after surgery that surpasses other restorations, and is a prime reason for their success rate. Although installing implants can be an expensive undertaking, their proven longevity may result in less maintenance, repair or replacement costs over time than other replacement options.
If you’re considering dental implants, remember it’s what you can’t see beneath the attractive crown that makes them special. And it’s a choice you can depend on to provide you a beautiful smile for years to come.

Most children's permanent teeth erupt on a fairly predictable schedule. Sometimes, though, one or more teeth might not develop as they should — or at all.
These absent teeth pose functional problems for chewing and hygiene, which can affect long-term dental health. But they can also have a disruptive effect on an otherwise attractive smile if the missing teeth are the upper lateral incisors in the most visible part of the smile.
You normally find this pair of teeth on either side of the upper central incisors (the two front-most teeth). On the other side of the lateral incisors are the canine or eye teeth, known for their pointed appearance. Without the lateral incisors, the canines tend to drift into the space next to the central incisors. This can produce an odd appearance even a layperson will notice: only four teeth where there should be six!
It's possible to correct this abnormality, but it will take time and expense. The first step is usually to move the teeth in the upper jaw with braces to their correct position. This puts teeth where they should be and also opens space between the canines and central incisors so we can eventually replace the missing teeth with dental implants.
But the key to all this is timing. It's usually appropriate to undertake tooth movement with braces during late childhood or adolescence. But implants shouldn't be installed until the person's jaw fully matures, usually in early adulthood. An implant placed before then could eventually become misaligned.
To accommodate the time between bite correction and implant placement, the patient can wear a retainer appliance that will keep the newly created space open. We can also attach artificial teeth to the retainer to camouflage the empty space.
It usually takes a team of a family dentist, an orthodontist and a surgeon to see this kind of “smile makeover” project through, possibly over several years. But the gains in better aesthetics and health are well worth the time and expense.
