TeensMayNeedaTemporaryReplacementforMissingTeeth

Tooth replacement at any age is a challenge, but especially for teenagers. Dental implants in particular may not be possible yet for teens or young adults whose jaws are still developing. Because it’s imbedded directly into bone, the implant will not move with the jaw as jaw growth occurs, making it look potentially unattractive.

The best solution could be a temporary replacement until their jaw reaches maturity. One such option is a removable partial denture (RPD), an artificial tooth set in an acrylic base that resembles gum tissue. Although we associate dentures with older adults, an RPD works well for teens as a temporary measure. Perhaps the best version for a younger person utilizes metal clips that fit over adjacent teeth and hold the RPD in place. Although quite resilient, the wearer needs to be careful when biting into something hard (like an apple or similar firm fruit) or the artificial tooth may break off.

Another option, a bonded bridge, is a fixed solution similar to a traditional bridge. Whereas a traditional bridge is supported by crowns affixed to the teeth on either side of the empty socket (and requiring extensive alteration of the teeth to accommodate them), a bonded bridge attaches to the supporting teeth with wing-like projections of dental material that attaches to the backs of the adjacent teeth, hidden from view. Although not as secure as a traditional bridge, they can conceivably endure until the teen’s jaw structure is ready for an implant or other permanent solution.

Choosing between an RPD and a bonded bridge will depend on a number of factors, including the teen’s individual bite, clenching or biting habits and the health and strength of supporting bone and gums. Regardless of the type of solution chosen, it’s important to maintain good oral hygiene, especially around a bridge. If bacterial plaque is allowed to build up on tooth surfaces, it could result in an infection that can damage both gums and bone, and reduce the chances of a successful implant in the future.

All these and other considerations should be discussed after a thorough examination. From there, we can advise you on the best course of action to restore both appearance and function until it’s time for a permanent restoration.

People with missing teeth have more replacement options than ever before, including the ever popular but often more expensive dental implant. But there has also been an expansion of choice on the more affordable side of dental restorations. The flexible removable partial denture (RPD) is one such choice. 

Though RPDs have been around for some time, the newer flexible RPD offers some advantages over the more rigid traditional RPD. They’re made of a kind of nylon that’s pliable but also strong and durable. This material is thermoplastic, meaning when heated it can be injected into molds based on a patient’s individual mouth to form an accurate denture base. The gum-colored base can also be formed to cover any receded areas of the gums, which can greatly improve smile appearance.

Older versions of RPDs are made of rigid acrylic plastic that stay in place in the mouth with metal clasps that attach to remaining teeth. The flexible RPD, on the other hand, is secured with finger-like nylon extensions that fit and hold in the natural teeth’s concavities near the gum line. This, along with its relatively light weight, offers a more comfortable fit.

But aside from these benefits, flexible RPDs do have a few drawbacks. Although fracture-resistant, they’re not easy to repair or reline to readjust the fit to accommodate mouth changes. They can stain (though not as much as a traditional RPD), so they require diligent cleaning and maintenance.

We consider the whole category of RPDs as “temporary” restorations, meaning they’re intended as a transitional phase between tooth loss and a permanent restoration like a natural tooth-supported fixed bridge or dental implants. For some, however, the flexible RPD might be a more long-term solution. As mentioned before, to extend their life as much as possible they should be removed daily and cleaned thoroughly. And like any form of denture, they should not be worn overnight.

In either case, flexible RPDs offer an effective way to restore not only dental function diminished by missing teeth but an improved appearance as well. With careful maintenance, they could serve you well for some time to come.

WaitingtoAffordImplantsConsideraFlexibleRPDintheMeantime

If you’ve lost some teeth you may eventually want to replace them with dental implants. Implants by far are the restoration of choice due to their life-likeness and durability. But those advantages don’t come cheaply — implants can be expensive especially for multiple teeth.

If you’re forced to wait financially for implants, you still have other intermediary options like a removable partial denture (RPD). The conventional RPD has a rigid acrylic base colored to resemble gum tissue supported by a metal frame with attached prosthetic (false) teeth at the missing teeth locations. They’re held secure in the mouth through metal clasps that fit over the remaining teeth.

But these conventional RPDs can sometimes be uncomfortable to wear and don’t always cover the bottom of the gum completely. If this is a concern, you might consider an alternative: flexible RPDs. The base of this RPD is made of a form of flexible nylon rather than acrylic plastic. They’re much more lightweight but still fit securely in the mouth with thin plastic extensions rather than metal clasps. The base can also be more easily formed to cover areas where gum tissue may have receded.

While flexible RPDs hold up better to wear and tear than their conventional counterparts, they must still be maintained like any other appliance. They can accumulate plaque (bacterial biofilm) responsible for tooth decay and periodontal (gum) disease, so daily thorough cleaning is a must. And if there fit becomes loose they can be more difficult to reline or repair than other types of dentures.

They also share a common weakness with other dentures — they can’t prevent and may even stimulate bone loss. As bone ages, old cells dissolve and new ones form to take their place. As we eat and chew our teeth transmit the forces generated through the teeth to the bone to stimulate it to grow. RPDs and other dentures can’t transmit this stimulus, so the bone replaces much slower to the point that the bone volume can diminish.

That’s why it’s best to consider any RPD as a temporary solution until you can obtain an implant for a more permanent and bone-friendly option. In the meantime, though, an RPD can provide you with a great solution for both form and function for missing teeth.
