Before implants, people often turned to a removable appliance to replace multiple missing teeth. Known as a removable partial denture (RPD), this appliance could restore both appearance and function at an affordable price.
But although implants may have diminished their use, RPDs haven't gone extinct. They're still a viable option for patients who can't afford implants or fixed bridgework, or who can't obtain implants due to the state of their dental health.
Although replacing only a few teeth rather than an entire arch, RPDs are similar in basic concept to full dentures. The prosthetic (artificial) teeth are anchored in a resin or plastic that's colored to resemble the gums, precisely placed to fit into the missing gaps. This assembly is further supported by a frame made of vitallium, a lightweight but strong metal alloy. The appliance fits upon the arch with the missing teeth, supported by vitallium clasps that grip adjacent natural teeth.
Each RPD must be custom designed for each patient to fit perfectly without excessive movement during chewing. Too much movement could warp the fit, reduce the RPD's durability or damage other teeth. To achieve this secure fit, dentists must take into account the number and location of missing teeth to be replaced, and then apply a specific construction pattern to balance the appliance.
There are RPDs that are meant to be used short-term, as with a teenager whose jaw isn't yet mature for dental implants. But the metal-framed RPDs we've described are designed for long-term use. There is, however, one primary downside: RPDs have a propensity to collect dental plaque, a thin biofilm most responsible for dental disease that could further deteriorate your dental health.
To avoid this, you'll need to keep both the RPD and the rest of your teeth and gums as clean as possible with daily brushing and flossing, and appliance care. And like dentures, it's best to remove the RPD when you go to bed at night to discourage the growth of harmful bacteria.
To see if an RPD to replace your missing teeth is an option for you, visit us for a complete dental exam. From there, we can advise you further as to whether an RPD could affordably restore your missing teeth and your smile.

If we were playing word association with the term “oral hygiene,” you'd probably answer “brushing.” And you would be right—brushing cleans tooth surfaces of accumulated bacterial plaque, a thin biofilm most responsible for dental disease.
But brushing is only half of the oral hygiene equation: You also need to remove dental plaque between teeth where brushing can't reach. And, that requires that other practice—flossing.
Unfortunately, brushing is more popular than its hygienic sibling because many people find traditional thread flossing more difficult and messier than brushing. That can make it tempting to skip flossing—but then you're only getting half the benefit of oral hygiene for reducing the risk of tooth decay or gum disease.
There is, however, a way to floss that doesn't involve a roll of thread: oral irrigation. This form of flossing uses a countertop device that directs a pressurized spray of water between teeth through a handheld wand. The directed spray loosens and then flushes away accumulated plaque.
Oral irrigators (also known as water flossers) have been an important tool for decades in dental offices, and have been available for home use since the 1960s. In the last few years, though, the devices have become more compact and easier to use. More importantly, studies have shown they're as effective in removing between-teeth plaque as regular flossing.
These irrigation devices are especially useful for people wearing braces. The attached brackets and wires make it extremely difficult to maneuver flossing thread between teeth. Because of this (as well as similar difficulties in brushing), patients are more susceptible to dental disease while undergoing orthodontic treatment.
But a 2008 study showed that oral irrigators are quite effective for braces wearers in removing between-teeth plaque. It found those who used an irrigator after brushing removed five times the amount of plaque than those that only brushed.
Even if you're not wearing braces, you may still find an oral irrigator to be a useful flossing alternative. Speak with your dentist for recommendations on what to look for in an oral irrigator and tips on how to use it. It could make a positive difference in your dental health.

Kathy Bates has been a familiar face to filmgoers since her Oscar-winning performance as Annie Wilkes in Misery. She's best known for playing true-to-life characters like Wilkes or Barbara Jewell in last year's Richard Jewell (for which she earned her fourth Oscar nomination). To keep it real, she typically eschews cosmetic enhancements—with one possible exception: her smile.
Although happy with her teeth in general, Bates noticed they seemed to be “moving around” as she got older. This kind of misalignment is a common consequence of the aging process, a result of the stresses placed on teeth from a lifetime of chewing and biting.
Fortunately, there was an orthodontic solution for Bates, and one compatible with her film career. Instead of traditional braces, Bates chose clear aligners, a newer method for moving teeth first introduced in the late 1990s.
Clear aligners are clear, plastic trays patients wear over their teeth. A custom sequence of these trays is developed for each patient based on their individual bite dimensions and treatment goals. Each tray in the sequence, worn in succession for about two weeks, places pressure on the teeth to move in the prescribed direction.
While clear aligners work according to the same teeth-moving principle as braces, there are differences that make them more appealing to many people. Unlike traditional braces, which are highly noticeable, clear aligners are nearly invisible to others apart from close scrutiny. Patients can also take them out, which is helpful with eating, brushing and flossing (a challenge for wearers of braces) and rare social occasions.
That latter advantage, though, could pose a problem for immature patients. Clear aligner patients must have a suitable level of self-responsibility to avoid the temptation of taking the trays out too often. Families of those who haven't reached this level of maturity may find braces a better option.
Clear aligners also don't address quite the range of bite problems that braces can correct. Some complex bite issues are thus better served by the traditional approach. But that gap is narrowing: Recent advances in clear aligner technology have considerably increased their treatability range.
With that said, clear aligners can be an ideal choice for adults who have a treatable bite problem and who want to avoid the appearance created by braces. And though they tend to be a little more expensive than braces, many busy adults find the benefits of clear aligners to be worth it.
The best way to find out if clear aligners could be a viable option for you is to visit us for an exam and consultation. Like film star Kathy Bates, you may find that this way of straightening your smile is right for you.
