Removable partial dentures (RPDs) are a common replacement option for multiple lost teeth. However, they're not the best long-term option; in fact, one particular type of RPD could be a poor choice if you wish to wear them long-term.
Made primarily of plastic, these RPDs are sometimes referred to as “flippers” because of how the tongue can easily flip them out of the mouth. While some people see them as a permanent replacement for their lost teeth, in reality plastic-based RPDs are a transitional replacement — a stepping stone, if you will, to a permanent solution. They are most useful during healing following a periodontal procedure or during the waiting period after implant surgery.
However, they can pose problems to your long-term oral health if worn permanently. Because of the manner in which they fit to the gums and any remaining teeth, they tend to settle into and compress the gum tissues. If you have gum disease, they force infection deeper into the tissues. They also allow and promote bacterial plaque growth. This in turn may lead to increased incidences of decay and gum disease.
On the other hand, a metal RPD, ideally made of cast vitallium or gold alloy, fits more snugly and accurately in the mouth. They still can cause increased plaque and food retention, but if the wearer also adheres to sound daily oral hygiene practices, regular dental checkups and diligent care of the RPD, they can be used successfully for many years.
Although a metal RPD costs more than its plastic counterpart, they cost less than more permanent teeth replacements. They are lighter in weight than plastic RPDs and fit more securely to deflect the forces generated by biting.
In considering your options for replacing lost teeth, you should not view plastic transitional RPDs as a permanent solution, but rather as a temporary one until you can obtain a more permanent solution. And although not the most optimal choice, the metal RPD could be considered a more permanent cost-effective solution.

Many Hollywood luminaries use porcelain veneers to enhance their smiles. Take actress and singer Hilary Duff, who, according to People magazine, had veneers placed on her two front teeth after chipping them on a microphone during what must have been an extremely energetic performance.
Well, you don't have to be a Hollywood star to benefit from a smile enhanced with porcelain veneers. If you have small chips, cracks, slight tooth rotations or minor spacing problems, veneers may be able to give you back your smile — or an even better one.
The word “veneer” refers to a super-thin covering, and in dentistry a veneer is a thin layer of porcelain that replaces your natural tooth enamel. Porcelain is the material of choice because of its strength, translucency, and ability to resist erosion.
In the right hands, dental porcelain can mimic tooth enamel perfectly. To make veneers, a skilled dental technician will mix porcelain powder (in a shade specified by the dentist) with water and then fire the material in an oven like pottery; the porcelain is built up in layers for a truly lifelike effect.
Before a veneer is bonded to a tooth, often we need to remove a tiny bit of the tooth's existing enamel so that the final effect will not be too bulky. The procedure is virtually painless and can be completed in as little as two visits. Because enamel is removed, this particular cosmetic treatment is not reversible. Sometimes veneers can be added directly onto the tooth surface without any tooth reduction and therefore are reversible if used in this way.
Once you have veneers, please keep in mind that while extremely strong, porcelain veneers are not indestructible; you won't want to do things like crunch ice or break nuts open with your teeth. And if you are a teeth-grinder, you should wear a nightguard to protect your beautiful new smile. With proper care, your veneers will last 20 years or more.
