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.

Your teeth and gums are filled with nerves that make the mouth one of the most sensitive areas in the body. But thanks to local anesthesia, you won't feel a thing during your next dental procedure.
The word anesthesia means “without feeling or pain.” General anesthesia accomplishes this with drugs that place the patient in an unconscious state. It's reserved for major surgery where the patient will be closely monitored for vital signs while in that state.
The other alternative is local anesthesia, which numbs the area that needs treatment, while allowing the patient to remain conscious. The anesthetics used in this way are applied either topically (with a swab, adhesive patch or spray) or injected with a needle.
In dentistry, we use both applications. Topical anesthesia is occasionally used for sensitive patients before superficial teeth cleaning, but most often as an “opening act” to injected anesthesia: the topical application numbs the gums so you can't feel the prick of the needle used for the injectable anesthetic. By using both types, you won't feel any pain at all during your visit.
Because of possible side effects, we're careful about what procedures will involve the use of local anesthesia. Placing a sealant on the exterior of a tooth or reshaping enamel doesn't require it because we're not making contact with the more sensitive dentin layer beneath. We've also seen advances in anesthetic drugs in which we can now better control the length of time numbness will persist after the procedure.
All in all, though, local anesthesia will make your dental care more comfortable — both for you and for us. Knowing you're relaxed and comfortable allows us to work with ease so we can be unhurried and thorough. By keeping pain out of the equation, your dental care has a better chance for a successful outcome.

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.
