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.
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.

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.
