Dental implants are today’s preferred choice for replacing missing teeth. They’re the closest restoration to natural teeth—but at a price, especially for multiple teeth. If implants are beyond your current financial ability, there’s an older, more affordable option: a removable partial denture (RPD).
Similar in concept to a full denture, a RPD replaces one or more missing teeth on a jaw. It usually consists of a lightweight but sturdy metal frame supporting a resin or plastic base (colored pink to mimic gum tissue). Prosthetic (false) teeth are attached to the base at the locations of the missing teeth. Unlike transitional dentures, RPDs are designed to last for many years.
Although simple in concept, RPDs certainly aren’t a “one-size-fits-all” option. To achieve long-term success with an RPD we must first consider the number of missing teeth and where they’re located in the jaw. This will dictate the type of layout and construction needed to create a custom RPD.
In addition, we’ll need to consider the health and condition of your remaining teeth. This can be important to an RPD’s design, especially if we intend to use them to support the RPD during wear. Support is a fundamental concern because we want to prevent the RPD from excessively moving in place.
Besides dental support we’ll also need to take into account how the jaws function when they bite. The RPD’s design should evenly distribute the forces generated when you eat and chew so as not to create undue pressure on the bony ridges of the jaw upon which the RPD rests. Too much pressure could accelerate bone loss in the jaw, a common issue with dentures.
It takes a lot of planning to create a comfortably-fitting RPD with minimal impact on your dental health. But you’ll also have to maintain it to ensure lasting durability. You should clean your RPD daily, as well as brush and floss the rest of your teeth to minimize the chances of developing tooth decay or periodontal (gum) disease. You can further discourage disease-causing bacterial growth by removing them at night while you sleep.
A RPD can be a viable alternative to more expensive restorations. And with the right design and proper care it could serve you and your smile for a long time to come.

Modern dentistry offers several great ways to permanently replace missing teeth, including high-tech dental implants and traditional fixed bridgework. But sometimes, for one reason or another, it isn’t possible to have these treatments done right away. If you need an aesthetic way to temporarily replace missing teeth, a flexible partial denture could be the answer you’re looking for.
Certain kinds of removable partial dentures (RPDs) can be used as permanent tooth replacement systems, especially for people who aren’t candidates for dental implants or fixed bridges. But in the past, if you needed a temporary tooth replacement, one of the few alternatives was the type of rigid RPD often called a “flipper.” This consists of a firm, relatively thick acrylic base that supports one or more lifelike replacement teeth. It attaches to the “necks” of existing natural teeth via metal clasps, which gives it stability and strength.
However, the same rigidity and thickness that gives these rigid RPDs their durability can make them uncomfortable to wear, while the acrylic material they are made of is capable of staining or breaking. Over time, the RPDs are prone to coming loose — and they are also easy to flip in and out with the tongue, which gives them their nickname.
Flexible partial dentures, by contrast, are made of pliable polyamides (nylon-like plastics) that are thin, light and resistant to breakage. Instead of using metal wires to attach to the teeth, flexible RPDs are held securely in place by thin projections of their gum-colored bases, which fit tightly into the natural contours of the gumline. Their elasticity and light weight can make them more comfortable to wear. Plus, besides offering aesthetic replacements for missing teeth, their natural-looking bases can cover areas where gums have receded — making existing teeth look better as well.
All RPDs must be removed regularly for thorough cleaning — but it’s especially important for flexible RPD wearers to practice excellent oral hygiene. That’s because the projections that hold them in place can also trap food particles and bacteria, which can cause decay. And, like most dentures, RPDs should never be worn overnight. Yet with proper care, flexible RPDs offer an inexpensive and aesthetic way to temporarily replace missing teeth.
You would love to replace your missing teeth with dental implants. And for good reason — they're the best way to restore life-like, functional teeth. But there's one problem — implants and fixed bridgework (the next, best option) are financially out of your reach.
There's another viable option, though, that might fit your budget — removable partial dentures (RPDs). Similar to full dentures, RPDs replace only the missing teeth in a dental arch. And they're much less expensive than implants or bridgework.
RPDs are custom made to fit an individual patient and their particular missing teeth locations. Their frameworks are usually made of vitallium, a strong but lightweight metal alloy. With vitallium, the frame can be made thin enough not to be noticeable but still conduct sensation.
A pink resin or plastic that mimics gum tissue covers the frame, to which we attach prosthetic (false) teeth made of porcelain, glass-filled resin or plastic to precisely match the missing teeth locations. The RPD is held in place with small metal clasps that fit around remaining natural teeth.
RPDs are designed to minimize movement and avoid undue pressure on the gum ridges, which could accelerate underlying bone loss. In certain situations, though, the location of some missing teeth could complicate matters. If you're missing a tooth in the back where the appliance coverage ends, the RPD may not be as stable.
The solution, ironically, could be a dental implant placed strategically at the end of the RPD, where it connects securely with the appliance. You would only need one or two implants, which won't dramatically increase costs.
One thing to remember with an RPD: they tend to accumulate bacterial plaque, the trigger for both tooth decay and periodontal (gum) disease. That's why it's important to practice daily effective hygiene by cleaning the RPD and your remaining teeth and gums, as well as taking the RPD out at night.
A well-maintained RPD could last for many years. With this appliance you can still have functional teeth and a winning smile, even without implants.
