While anyone can lose a permanent tooth, the cause often varies by age group. Adults usually lose their teeth to disease, while those under twenty lose a tooth to accidents.
For adults, a dental implant is usually the best way to replace a missing tooth. Teenagers and younger, on the other hand, must wait to get implants until their jaws fully develop. An implant placed on an immature jaw will eventually look and feel out of place.
For most, their jaws won't reach full maturity until their early twenties. Even so, they still have a couple of good options for restoring their smiles in the meantime, albeit temporarily.
One is a removable partial denture or RPD, a device with the replacement prosthetic (false) tooth or teeth set in a gum-colored acrylic base. Of the various types of RPDs, most teenagers do well with a rigid but lightweight version called a “flipper,” called so because it can be flipped in and out of place with the tongue.
These RPDs are affordable, their fit easily adjusted, and they make cleaning the rest of the teeth easier. But they can break while biting down hard and—because they're dentures—aren't always well accepted among teenagers.
The other option is a bonded bridge. Unlike a traditional bridge secured with crowns cemented to natural teeth, a bonded bridge uses a strip of dental material affixed to the back of the prosthetic tooth with the ends of the strip extending outward horizontally. With the prosthetic tooth inserted into the empty space, these extended ends are bonded to the backs of the natural teeth on either side.
Though not as secure as a traditional bridge, a bonded bridge is more aesthetic and comfortable than an RPG. On the other hand, patients who have a deep bite or a teeth-grinding habit, both of which can generate abnormally high biting forces, run a higher risk of damaging the bridge. A bridge can also make hygiene tasks difficult and time-consuming, requiring a high degree of self-discipline from the patient.
Whichever you choose, both options can effectively replace a teenager's missing tooth while waiting for dental implants. Although temporary, they can make the long wait time for a teenager more bearable.
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.

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.

In an ideal situation, you would transition from a missing tooth to a permanent replacement with as little time in between as possible. Unfortunately, reality can intrude on the best of intentions.
For example, dental implants are one of the best ways to regain the form and function of a lost tooth. They are, however, initially expensive, especially if you’re replacing multiple teeth. Your financial ability may force you to wait — which means you need a solution now, if only temporarily.
Fortunately, a removable partial denture (RPD) could be the temporary solution you’re looking for. There are various kinds and all quite affordable; one of the more versatile is a flexible version made of a form of nylon. Due to its thermoplasticity, the nylon is quite pliable when heated and can be easily molded into a denture base with attaching prosthetic teeth. They’re comfortable to wear and attach to the remaining teeth at the gum line with flexible, finger-like clasps.
Â RPDs are designed as a transitional replacement between tooth loss and a permanent restoration such as implants, bridges or permanent dentures. Their light weight, comfort and affordability also make them tempting to consider as a permanent replacement.
They do, however, have some drawbacks that make them less desirable for long-term use. They weren’t designed for relining or repair, so such efforts can be difficult. The clasp holding them in place may also trap food and bacteria that increase the risk of dental disease to the gums and remaining teeth. You can minimize some of these weaknesses by properly cleaning and maintaining the RPD, and taking them out at night to inhibit the growth of bacteria while you sleep.
Mainly, though, you should primarily consider a RPD as a temporary bridge between lost teeth and a permanent restoration. To that end, we’ll work with you to develop a treatment and finance plan that will help you achieve a more permanent and satisfying restoration.
