Dentures in one form or another have been around for centuries. Although dental implants have earned a well-deserved prominence of late, the denture still remains a viable tooth replacement option.
What's more, dentures aren't reserved for total tooth loss only. Even if you've lost just a few of your teeth, we can fit you with a removable partial denture (RPD). Although mainly considered a temporary solution for missing teeth, some people depend on an RPD for many years due to finances or other issues.
The traditional RPD consists of a rigid acrylic plastic base that resembles gum tissue supported by a metal framework, with prosthetic (false) teeth precisely placed to fill the space of the missing teeth. They're held in place with metal clasps that extend from the metal framework to fit over the remaining natural teeth.
Although they're an effective restoration, traditional RPDs have a few drawbacks. Some people find them uncomfortable to wear or have an allergy to the acrylic plastic. They also have a propensity to stain from beverages like tea, coffee or wine.
But there's a more recent version called a flexible RPD that addresses these and other concerns. It's made of a pliable nylon that's durable, yet comfortable to wear. Rather than metal clasps, they're secured in place with thin, finger-like nylon extensions that fit into the small, natural depressions in the crowns of the teeth around the gum line.
Flexible RPDs are also highly adaptable to appear life-like in many situations. We can fashion the nylon base to cover areas around natural teeth where the gums may have receded due to gum disease.
They do, however, have a few downsides. Unlike traditional dentures, they're difficult to reline or repair. Like any oral appliance, they can suffer from wear and neglect, so you must properly clean and maintain them. And, like any RPD their best role is as a temporary bridge rather than a permanent restoration.
In the meantime, though, you can count on a flexible RPD to restore your ability to eat and speak proficiently, as well as smile with confidence. It's a great affordable way to address a few 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.

Besides reduced biting and chewing function, a missing tooth can cause an embarrassing inhibition to healthy social interaction. This can be especially so for teens who greatly value peer relationships and acceptance.
Be that as it may, we typically discourage a permanent replacement for teens with a missing tooth, particularly dental implants. While we value a patient’s psychological needs, the long-term effect on dental health may be too great to advise otherwise.
The effect we’re concerned with involves jaw growth and development. Although a person’s permanent teeth have usually all erupted by early adolescence, the jaws continue to grow until the late teens or early twenties. Natural teeth can adapt to this growth because the periodontal ligament that holds them in place allows for incremental tooth movement. The teeth move in response to jaw growth and are thus able to maintain their proper relationship and alignment in the jaw as growth occurs.
Dental implants, on the other hand, are imbedded into the jaw bone: they, therefore, can’t move like natural teeth and thus can’t adjust their position with jaw growth, particularly the upper jaw as it grows forward and down. This can result in the implants appearing as though they are left behind or retreat into the jaw. It can also affect the position of the gums and inhibit their growth around the implants.
It’s best then to hold off implants and other permanent restorations until the jaw has finished developing. That, however, isn’t always easy to determine: specialized x-ray diagnostics may help, but it’s not an exact science. Your input as a parent will also be helpful, such as whether you’ve noticed the end of growth spurts (not changing clothes or shoe sizes as often) or your child’s recent similarity in appearance to other adult members of your family. It thus becomes a judgment call, based on examination and experience, as to whether it’s safe to proceed with implants — and may require erring on the side of caution.
In the meantime, there are temporary restorations that can improve appearance while you wait for the appropriate time to undertake a permanent restoration. Two of the most useful are removable partial dentures (RPDs) or a bonded bridge, a less invasive form of the traditional bridge. With a proper assessment we can advise you on which option is your best choice.

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.
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.
