The timing around losing a tooth may not always sync with your financial ability. It's not unusual for people to postpone getting a dental implant—by far the best option for replacing a missing tooth—because of its expense.
So, if you have to postpone dental implants until you can afford them, what do you do in the meantime to keep your smile intact? One affordable option is a temporary restoration known as a flexible removable partial denture (RPD).
Composed of a kind of nylon developed in the 1950s, flexible RPDs are made by first heating the nylon and injecting its softened form into a custom mold. This creates a gum-colored denture base to which prosthetic (false) teeth are affixed at the exact locations for missing teeth.
Differing from a permanent RPD made with rigid acrylic plastic, a nylon-based RPD is flexible and lightweight, making them comfortable to wear. They're kept in place with small nylon extensions that fit into the natural concave spaces of teeth. And, with a bit of custom crafting, they can look quite realistic.
RPDs are helpful in another way, especially if you're waiting for an implant down the road: They help preserve the missing tooth space. Without a prosthetic tooth occupying that space, neighboring teeth can drift in. You might then need orthodontic treatment to move errant teeth to where they should be before obtaining a permanent restoration.
Flexible RPDs may not be as durable as acrylic RPDs, and can be difficult to repair or reline if needed to adjust the fit. Though they may not stain as readily as acrylic dentures, you'll still need to clean them regularly to help them keep looking their best. This also aids in protecting the rest of your mouth from dental disease by removing any buildup of harmful bacterial plaque on the RPD.
But even with these limitations, patients choose RPDs for the simple fact that they're affordable and temporary. And the latter is their greatest benefit—providing you a “bridge” between losing a tooth and replacing it with a durable dental implant.

Dentures have come a long way since George Washington's time. Today, they're more comfortable, more secure and more lifelike than our first president's famous hippopotamus ivory appliance.
But one thing hasn't changed: Dentures still require regular care and cleaning. And one of the best things you can do for both your dentures and your health is to take them out at night when you go to bed.
Modern dentures are often so comfortable to wear, it's easy to forget you have them in your mouth. But setting a daily habit of taking them out when you turn in for the night will help you avoid a few potential problems.
For one, wearing dentures 24/7 can increase your risk for both oral and general diseases. Constant denture wear can cause greater accumulations of dental plaque, a thin biofilm responsible for gum disease and inflammation. The increase in bacteria could also make you more susceptible to pneumonia and other diseases.
Wearing your dentures non-stop can also worsen bone loss, a common problem associated with dentures. Normally, the biting forces generated when we chew stimulate bone growth in the jaw. A person loses much of this stimulation when they lose teeth, resulting in gradual bone loss.
Dentures can't replace this lost stimulation, and the pressure they exert on the jaw's bony ridges they rest upon can accelerate the process of bone loss. In time, any bone loss could affect the denture's fit as the bone beneath them gradually shrinks. By taking them out at night, you can help slow the pace of bone loss.
In addition to giving them and your mouth a rest at night, be sure you're also keeping your dentures clean: Take them out and rinse them off after meals and brush them with a small amount of antibacterial soap (not toothpaste) at least once a day. And don't forget to brush your gums and tongue every day with a soft toothbrush (different from your denture brush) to further reduce dental plaque.

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.

Even in the 21st Century, losing most or all of your teeth is still an unfortunate possibility. Many in this circumstance turn to dentures, as their great-grandparents did, to restore their teeth. But today's dentures are much different from those of past generations—and dental implants are a big reason why.
The basic denture is made of a gum-colored, acrylic base with artificial teeth attached. The base is precisely made to fit snugly and comfortably on the patient's individual gum and jaw structure, as the bony ridges of the gums provide the overall support for the denture.
Implants improve on this through two possible approaches. A removable denture can be fitted with a metal frame that firmly connects with implants embedded in the jaw. Alternatively, a denture can be permanently attached to implants with screws. Each way has its pros and cons, but both have two decided advantages over traditional dentures.
First, because implants rather than the gums provide their main support, implant-denture hybrids are often more secure and comfortable than traditional dentures. As a result, patients may enjoy greater confidence while eating or speaking wearing an implant-based denture.
They may also improve bone health rather than diminish it like standard dentures. This is because the forces generated when chewing and eating travel from the teeth to the jawbone and stimulate new bone cell growth to replace older cells. We lose this stimulation when we lose teeth, leading to slower bone cell replacement and eventually less overall bone volume.
Traditional dentures not only don't restore this stimulation, they can also accelerate bone loss as they rub against the bony ridges of the gums. Implants, on the other hand, can help slow or stop bone loss. The titanium in the imbedded post attracts bone cells, which then grow and adhere to the implant surface. Over time, this can increase the amount of bone attachment and help stymie any further loss.
An implant-supported denture is more expensive than a standard denture, but far less than replacing each individual tooth with an implant. If you want the affordability of dentures with the added benefits of implants, this option may be worth your consideration.

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.
