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.

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.

Considering the costs, many people view replacing a back tooth as less important than a more visible front tooth. They’re rarely seen, so who will notice?
You might, eventually. A missing back tooth can set off a chain reaction of problems that can affect your overall dental health. Besides playing an important role in chewing food, back teeth also redistribute most of the chewing force away from the front teeth. Their absence can also affect the bite: adjacent teeth to the missing one will tend to migrate toward the open space, causing them to tip and rotate into an improper position. This can cause an increase in tooth mobility, excessive wear and erosion, and endanger their survival in the long run.
To avoid these and other problems you should consider some form of replacement. Most dentists prefer a dental implant for its life-like appearance and durability, and because its titanium post has a natural affinity with bone. Bone cells will grow around and permanently adhere to the implant, which may stop and even reverse bone loss in some cases.
Implants, though, require a certain amount of bone structure initially to anchor and position properly. If you have inadequate bone and don’t want to bone graft the area, the next best option is a fixed bridge, in which the missing tooth is replaced with an artificial crown known as a pontic. The pontic is fused between two support crowns that are permanently affixed to the natural teeth on either side of the missing tooth (also known as abutments). While fixed bridges restore function and inhibit tooth migration, they require the natural tooth supporting the bridge to be reduced to accommodate the crowns placed on them. This permanently alters them and places them at higher risk for future nerve damage, gum disease and decay.
One final option is a removable partial denture (RPD). Although RPDs restore function and improve appearance, their movement within the mouth may place additional stress on the teeth that hold them in place. This movement over time could damage or loosen them.
We can discuss which option is best for you after a complete dental exam. The important thing, though, is to replace the back tooth as soon as possible — doing nothing could cost you much more in the long run.
