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.
There's no doubt about it — dentures have changed your life. Now you can eat and speak normally, and smile again with confidence. But if you're going to continue to benefit from your dentures, you'll need to take care of them. One of the best things you can do is not sleep with them in.
There are a couple of important reasons why you should take your dentures out when you go to bed. First, dentures tend to compress the bony ridges of the gums that support them. This contributes to the loss of the underlying bone, an occurrence common with missing teeth. Wearing dentures around the clock can accelerate this bone loss, which eventually loosens your denture fit.
Constant denture wearing also contributes to mouth conditions conducive to dental disease. You're more likely to develop tongue and denture plaque (a thin film of bacteria and food particles) that can cause gum inflammation or yeast development. The presence of the latter could also trigger a chronic response from your immune system that might make you more susceptible to other diseases.
Good oral hygiene is just as important with dentures as with natural teeth. Besides removing them at night, you should also take them out and rinse them after eating and brush them at least once a day with a soft tooth brush. And be sure to use regular dish or hand soap (especially antibacterial) or denture cleanser — toothpaste is too abrasive for denture surfaces.
It's also a good habit to store your dentures in water or, better, an alkaline peroxide solution. This will help deter plaque and yeast development. And don't forget the rest of your mouth: brush your tongue and gums with a very soft toothbrush (different from your denture brush) or clean them off with a damp cloth.
Taking care of your dentures will ensure two things. You'll lower your risk for disease — and you'll also help extend your dentures' life and fit.
After a long struggle with dental disease, you have finally lost the last of your remaining teeth.Â Like over a quarter of Americans in their 60s and 70s, this unfortunate development can have a profound impact on your health and self-image.
While there are a number of advanced methods for replacing lost teeth, there's one tried and true option that's centuries old — the removable denture. It's the option millions of people have chosen to lessen the impact of missing teeth.
Fashioned properly, removable dentures restore the form and function you once had with your natural teeth. The prosthetic (false) teeth are precisely placed in an acrylic, gum-colored base that closely follows the contours of your gums. Because they're removable, they're fairly easy to clean and maintain.
They do have a disadvantage, though, and it's related to bone health after tooth loss. Like other living tissues, bone has a life cycle: as older cells die, new cells form to take their place. The forces your teeth generate when you chew stimulate new bone growth. But without teeth to provide this stimulation, new bone won't keep up the pace of replacement at a healthy rate. As a result you may gradually lose bone, as much as a quarter of its normal width within a year of losing a tooth.
Dentures don't transmit any stimulation to the gum and bone from chewing. Furthermore, the compressive forces transmitted to the gum and underlying bone tissue contributes to bone loss. As the bone continues to diminish, your denture fit becomes looser to the point you will eventually need them relined with new acrylic material or have a new set made.
There is another alternative when patients loose all of their teeth: an implant-supported removable denture. Dental implants can be used to keep the dentures more secure and can also slow or even halt bone loss where the implants are placed. In this case we strategically place a few implants to serve as supports for a removable denture. The denture has connection points that join up with the implants to hold it more securely in place. As few as two implants are needed in the lower jaw, while the upper jaw does better with three or four implants.
Losing all your teeth can be traumatic, but there are effective ways to overcome it. With new technology, the traditional restoration of removable dentures may be the vehicle for achieving that.

Edentulism, the loss of all of a person’s teeth, is more than an appearance problem. As one in four Americans over 65 can attest, total tooth loss can lead to emotional suffering, social embarrassment and a lack of nutrition caused by limited food choices.
But there are solutions like the removable denture, an effective dental restoration for more than a century. In its current advanced form, the removable denture is truly a functional, affordable and attractive way to restore lost teeth.
Creating an effective denture begins first by taking detailed impressions of a patient’s gum ridges. We use the measurements obtained from this process to create a plastic resin base colored to resemble the natural gums. Using old photos and other resources documenting how the patient looked with teeth, we choose the best size and shape of porcelain teeth and then position them onto the base.
Finally, we fine-tune the dentures the first time they’re in the patient’s mouth to make sure they have a secure fit and a balanced bite when the jaws come together. We also want to be sure the dentures are attractive and blend well with other facial features. The result: a new set of teeth that can do the job of the old ones and look nearly as real and attractive.
Dentures, though, do have one major drawback: they can’t stop bone loss, a common consequence of missing teeth. In fact, they may even accelerate bone loss due to the pressure they bring to bear on the gum ridges. Continuing bone loss could eventually cause their once secure fit to slacken, making them less functional and much more uncomfortable to wear.
But a recent innovation could put the brakes on bone loss for a denture wearer. By incorporating small implants imbedded at various places along the gums, a denture with compatible fittings connects securely with the implants to support the denture rather than the gum ridges. This not only relieves pressure on the gums, but the titanium within the implants attracts bone cells and stimulates their growth.
Thanks to this and other modern advances, dentures continue to be a solid choice for tooth replacement. Not only can they restore a lost smile, they can improve overall health and well-being too.

Some patients who wear dentures face a kind of Catch-22: their denture fit may have loosened and become uncomfortable over time due to continued bone loss, yet the same bone loss prevents them from obtaining dental implants, a superior tooth replacement system to dentures.
But there may be a solution to this dilemma that combines the stability of implants with a removable denture. A set of smaller diameter implants — “mini-implants” — can support a removable denture with less bone than required by a conventional implant.
Like all living tissue, bone has a life cycle: after a period of growth, the older bone dissolves and is absorbed by the body, a process known as resorption. The forces generated when we bite or chew are transmitted by the teeth to the jawbones, which stimulates new bone formation to replace the resorbed bone. When the teeth are lost, however, the stimulation is lost too; without it, resorption will eventually outpace bone growth and repair, causing the bone mass to shrink.
Removable dentures also can’t supply the missing stimulation — bone loss continues as if the dentures weren’t there; and due to the compressive forces of a denture, bone loss accelerates. As the jawbone structure used to originally form the denture’s fit eventually shrinks, the denture becomes loose and difficult to wear. It’s possible to adjust to the new jaw contours by relining the dentures with new material or creating a new set of dentures that match the current bone mass. Without adequate bone, fixed crowns or bridges anchored by conventional implants may also be out of the picture.
On the other hand, mini-implants with their smaller diameter need less bone than the traditional implant. A few strategically placed within the jaw are strong and stable enough to support a removable denture. One other advantage: these mini-implants can be installed in one visit with local anesthesia and usually without the need for incisions or stitches.
