Dentures, removable restorations for missing teeth and gum tissue, can take a number of different forms, but are usually of two different types: complete and partial. A complete denture replaces all the teeth in a given arch. A removable partial denture (RPD), on the other hand, replaces several missing teeth while using the remaining teeth as support.
A common type of RPD formed of plastic is known as a “flipper” because it’s lightweight enough to be “flipped out” or moved around with the tongue. They serve an important purpose as a temporary appliance for use between periodontal treatment, implant placement and similar treatments before obtaining a more permanent restoration. In fact, they’re often referred to as “transitional” RPDs because they’re not designed for permanent tooth replacement.
Because of their low cost relative to other restorations, however, they often become the permanent choice for many people. While a well-constructed, properly fitting RPD in a healthy mouth can be an affordable alternative for people on modest budgets, their long-term use may increase the risk of dental disease and accelerated bone loss. Decades of research verify that people who permanently wear RPDs encounter more tooth decay and periodontal (gum) disease than non-wearers.
This is because the attachment points of a plastic RPD to remaining teeth increases bacterial growth, which can cause both tooth decay and gum disease. This doesn’t only endanger the survival of the remaining teeth, it can lead to bone loss that will affect the RPD’s fit.
While the better course is to consider RPDs as a stepping stone to dental implants or a fixed bridge, there’s an intermediary RPD constructed of cast vitallium or gold alloy that could be considered a permanent choice. These are even lighter weight than plastic and less obtrusive in their attachments in the mouth, which can reduce plaque stagnation and promote a better oral environment.
Regardless of your choice in dentures, it’s always important to maintain good consistent oral hygiene with daily brushing and flossing and semi-annual professional cleanings and checkups. Keeping a healthy mouth will help reduce your risk of dental disease and increase your satisfaction with your denture of choice.

Not long ago, the most affordable option for total tooth loss was a removable denture. Dentures, prosthetic (false) teeth set in gum-colored acrylic plastic bases, can effectively restore function and appearance. But the appliance continues to have one major drawback: it can accelerate bone loss in the jaw.
Like other living tissues, older bone cells die and become absorbed into the body (resorption). Normally they're replaced by newer cells. The forces generated when we chew our food travel through the teeth to stimulate this new growth. This stimulus ends when we lose our teeth, and so cell replacement can slow to an abnormal rate. Eventually, this causes bone loss.
Removable dentures can't provide this stimulation. In fact, the pressure generated as they compress the gums' bony ridges can even accelerate bone loss. That's why over time a denture's fit can become loose and uncomfortable — the bone has shrunk and no longer matches the contours of the dentures.
In recent years, though, a new development has been able to provide greater support to dentures while at the same time slowing or even stopping bone loss. We can now support dentures with dental implants.
Implants are best known as individual tooth replacements: a titanium metal post replaces the root, while a life-like porcelain crown attaches to the post to replace the visible tooth. In addition to providing a longer-lasting alternative to removable dentures, implants provide a very important health benefit: they improve bone density because they mimic the function of natural teeth. Bone cells are naturally attracted to the titanium; they adhere to the titanium post and are stimulated to grow through the action of chewing, increasing bone density and securing the implant's hold in the jaw.
Using the same technology we can support removable dentures, or even full fixed bridges. Rather than rest directly on the bony ridges, a denture can make a secure connection through a coupling system with just a few strategically placed implants. We can also permanently attach a full bridge by fastening it to a few implants with screws.
Not only do we eliminate the pressure from dentures compressing the gums and bone tissue, we can actually stimulate bone growth with the implants. Although more costly upfront than traditional dentures, unlike traditional dentures which must be replaced every five to seven years, long-lasting implants may be more cost-effective over the long-run.

Maybe you don’t like to be without teeth — ever. Or maybe you get a little forgetful sometimes. Whatever the reason, if you’re wearing your dentures to bed at night, we have one message for you: Please stop!
Sleeping in dentures can have serious health consequences. A recent study published in the Journal of Dental Research found that nursing home residents who wore their dentures to sleep were 2.3 times more likely to be hospitalized or even die of pneumonia as those who did not sleep in dentures. But how can wearing dentures at night more than double your chances of getting a lung infection?
As the study noted, pneumonia-causing bacteria can readily be moved from the mouth to the lungs simply by breathing. And dentures that are not removed at night can become breeding grounds for all kind of bacteria and fungi (such as yeast). That’s what makes them potentially dangerous.
Another condition often seen in people who wear upper dentures continually is called denture stomatitis, which is characterized by a red, inflamed palate (roof of the mouth) that has been infected with yeast. The yeast microorganisms can also infect cracked corners of the mouth, a condition known as angular cheilitis. Moreover, it has also been shown that people who sleep in dentures have higher blood levels of a protein called interleukin 6, which indicates that the body is fighting an infection. Need we go on?
Wearing dentures is supposed to improve your quality of life, not reduce it. So promote good health by taking your dentures out at night, and sticking to a good daily oral hygiene routine:
- Remove and rinse your dentures after every meal.
- Brush your dentures at least once a day with a soft toothbrush or denture brush and dish soap, liquid antibacterial soap, or denture cleanser (but don’t use toothpaste — it is too abrasive).
- Store your dentures in water or a solution made for this purpose.
- Brush your gums and tongue every day with a soft toothbrush (not the same one you clean your dentures with).
- Rinse your dentures in clean water before you put them back in your mouth.
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.

What does the term “two-implant overdentures” mean?
For more than a century, complete dentures were the only care option for edentulous (toothless) people. As a solution, these left a lot to be desired, particularly for the lower jaw. Now dental technology has developed a better alternative that combines two strategically placed dental implants and a traditional lower denture that has been modified to fit over the two implants — thus the term.
What are the problems with traditional dentures?
The problem is that when you lose teeth, the bone that supported the missing teeth begins to shrink away. This is known as resorption, and it is the reason that dentures fitted too soon after teeth are lost quickly become loose. Bone loss happens most rapidly during the first year and is four times greater in the lower jaw than in the upper.
Why not just use dental adhesives to hold dentures tightly to the lower jaw?
Zinc, a major ingredient in most dental adhesives, has been associated with neurological disorders and may be unsafe. In addition, dental adhesives are expensive and the cost of frequent usage adds up.
Besides dental adhesives, are other health problems associated with dentures?
Yes, edentulism has been related to poor nutrition. Many edentulous people switch to soft foods with high fat content because they find healthier foods like vegetables and proteins difficult to chew.
What are dental implants?
Dental implants are replacements for the roots of teeth, the parts that are below the gumline and anchored in bone. They are usually covered with a crown that shows above the line of the gums.
What are the benefits of implants?
Most importantly, implants reduce the amount of bone resorption. Studies have shown about 75% less resorption in parts of the jaw with implants compared to areas without them. Since most of the bone loss occurs within the first year after tooth loss, it is important to place implants within this time period.
Is a complete set of dental implants a good solution for edentulism?
Yes, it can be a good solution, but it is not for everyone. Some patients, who have lost a great deal of bone support, need another solution for cosmetic reasons that offer more facial support like an implant overdenture. In addition, depending on their resources and insurance, some people require a less expensive solution.
Why does the two-implant overdenture work better for the lower jaw?
Based on differences in bone volume, density and other factors, we think that four to six implants are needed to retain an upper implant overdenture. Thus a two-implant overdenture is a good solution to consider for a lower jaw, but other options might be preferred for an upper jaw.
