We’ve come a long way in our ability to restore missing teeth. Today’s top choice is dental implants, prized not only for their close resemblance to real teeth but also their durability.
The rise of implants, though, hasn’t put older restorative methods out to pasture—many continue to offer patients a viable and affordable choice for tooth replacement. One example is the removable partial denture (RPD).
Once quite common, RPDs’ popularity has only slightly diminished with the advent of implants. They’re a fair option in terms of dental function and appearance, and much less expensive than implants or fixed bridges.
Similar to a full denture—a removable appliance that replaces all the teeth on a dental arch—a RPD can replace multiple missing teeth in a variety of configurations. A traditional RPD is usually constructed of vitallium, a lightweight but strong metal alloy, which allows for a very thin and comfortable frame. It’s covered in a gum-colored resin or plastic with prosthetic (false) teeth precisely set at the missing teeth’s locations. The appliance stays in place through a series of clasps that attach to the remaining teeth.
Each RPD is custom-made to fit a patient’s mouth contours and the locations and patterns of the missing teeth. The top design goal for each individual RPD is to minimize any rocking movement during chewing; achieving that goal will depend not only on how many teeth are missing and where, but also what type of teeth are being replaced. For example, teeth missing from the back would require a different support design than teeth missing from the side or front.
RPDs’ biggest benefits are comfortable fit, effective dental function and good appearance. However, their means of attachment can create difficulties keeping remaining teeth clean of disease-causing bacterial plaque. Furthermore, an ill-fitting or unstable RPD could damage or even loosen natural teeth. It’s therefore essential for wearers to diligently practice daily hygiene (including cleaning the RPD) and undergo regular fit monitoring with their dentist.
Even with these constraints, a RPD can do an acceptable job providing dental function. What’s more, it can definitely improve your smile.

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.
