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.

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.

For centuries, people who've lost all their teeth have worn dentures. Although materials in today's dentures are more durable and attractive than those in past generations, the basic design remains the same — prosthetic (false) teeth set in a plastic or resin base made to resemble gum tissue.
If you're thinking of obtaining dentures, don't let their simplicity deceive you:Â a successful outcome depends on a high degree of planning and attention to detail customized to your mouth.
Our first step is to determine the best positioning for the prosthetic teeth. It's not an “eyeball” guess — we make a number of calculations based on the shape and size of your jaws and facial features to determine the best settings within the resin base. These calculations help us answer a few important questions for determining design: how large should the teeth be? How far forward or back from the lip? How much space between the upper and lower teeth when the jaws are at rest?
We also can't forget about the artificial gums created by the base. How much your gums show when you smile depends a lot on how much your upper lip rises. We must adjust the base size to accommodate your upper lip rise so that the most attractive amount of gum shows when you smile. We also want to match as close as possible the color and texture of your natural gum tissues.
There's one other important aspect to manage: how your upper and lower dentures function together when you eat or speak. This means we must also factor your bite into the overall denture design. This may even continue after your dentures arrive: we may still need to adjust them while in your mouth to improve function and comfort.
Ill-fitting, dysfunctional and unattractive dentures can be distressing and embarrassing. But with careful planning and customization, we can help ensure your new dentures are attractive and comfortable to wear now and for years to come.

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.
