You probably can’t remember a time without your teeth — and can’t imagine life without them. But now it’s a reality: one by one your teeth have become casualties in a long-standing war with dental disease until now they’re all lost.
Total tooth loss (edentulism) can be difficult in more ways than the loss of function — it can be psychologically traumatic as you must now transition from natural teeth to dentures or other restorations. To add to the stress, you probably won’t be able to obtain your permanent restoration immediately because the extraction sites must heal.
To help you with this transition and provide a means for you to have teeth during the healing period, we may fit you with an appliance known as an immediate denture. With these temporary teeth replacements, you can maintain your smile appearance, chew food and speak unimpaired.
Initially, immediate dentures should fit well, but over time your gums will tend to shrink as they heal. This can loosen the dentures’ fit and make them uncomfortable to wear. If the healing process is still ongoing and you still need to wear the immediate dentures, they can be relined with more denture material to fine-tune the fit.
At some point, though, we must consider creating a new, permanent set of dentures. When your mouth is fully healed, we can make a more accurate impression that we can then use to construct your new set. There are also other options, such as using dental implants to support a denture or a fixed bridge. This option will only be possible, however, if you have sufficient bone available to fully support it, which we might also be able to augment with grafting.
Immediate dentures serve a worthwhile purpose, but only for a temporary period. We’ll be happy to discuss all your options with you to help you find the right permanent solution that fits both your mouth’s condition and your financial ability.

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.
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.

People who’ve lost all their teeth have benefitted from a solution that’s been around for generations: removable dentures. These appliances have helped millions of people chew and eat food, speak, and smile confidently.
But for all their benefits (including affordability) there’s still some things you need to do to get the most out of them like cleaning them daily or having us check them regularly for damage and wear. And, there’s one thing you shouldn’t do: wear them around the clock. Not removing them when you sleep at night can harm your oral health and reduce your dentures’ longevity.
Dentures are fitted to rest on the gums and the bony ridges that once held your natural teeth. This exerts pressure on the underlying bone that can cause it to gradually dissolve (resorb). This loss in bone volume eventually loosens your denture’s fit. If you’re wearing them all the time, the process progresses faster than if you took them out each night.
The under surfaces of dentures are also a prime breeding ground for bacteria and fungi. Besides unpleasant odors and irritation, these microorganisms are also the primary cause for dental disease. Research has found that people who sleep in their dentures have higher occurrences of plaque, a thin film of bacteria and food remnants that cause periodontal (gum) disease. They’re also more prone to higher levels of yeast and the protein interleukin-6 in the blood, which can trigger inflammation elsewhere in the body.
To avoid these and other unpleasant outcomes, you should develop a few important habits: remove and rinse your dentures after eating; brush them at least once a day with dish or anti-bacterial soap or a denture cleanser (not toothpaste, which can be too abrasive); and take them out when you sleep and place them in water or an alkaline peroxide-based solution.
Be sure you also brush your gums and tongue with an extra soft toothbrush (not your denture brush) or wipe them with a clean, damp washcloth. This will help reduce the level of bacteria in the mouth.
Taking these steps, especially removing dentures while you sleep, will greatly enhance your well-being. Your dentures will last longer and your mouth will be healthier.
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.
