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.

You can't correct a poor bite with braces or clear aligners overnight: Even the most cut-and-dried case can still require a few years to move teeth where they should be. It's a welcome relief, then, when you're finally done with braces or aligner trays.
That doesn't mean, however, that you're finished with orthodontic treatment. You now move into the next phase—protecting your new smile that took so much to gain. At least for a couple of more years you'll need to regularly wear an orthodontic retainer.
The name of this custom-made device explains its purpose: to keep or “retain” your teeth in their new, modified positions. This is necessary because the same mechanism that allows us to move teeth in the first place can work in reverse.
That mechanism centers around a tough but elastic tissue called the periodontal ligament. Although it primarily holds teeth in place, the ligament also allows for tiny, gradual tooth movement in response to mouth changes. Braces or aligner trays take advantage of this ability by exerting pressure on the teeth in the direction of intended movement. The periodontal ligament and nature do the rest.
But once we relieve the pressure when we remove the braces or aligners, a kind of “muscle memory” in the ligament can come into play, causing the teeth to move back to where they originally were. If we don't inhibit this reaction, all the time and effort put into orthodontic treatment can be lost.
Retainers, either the removable type or one fixed in place behind the teeth, gently “push” or “pull” against the teeth (depending on which type) just enough to halt any reversing movement. Initially, a patient will need to wear their retainer around the clock. After a while, wear time can be reduced to just a few hours a day, usually during sleep-time.
Most younger patients will only need to wear a retainer for a few years. Adults who undergo teeth-straightening later in life, however, may need to wear a retainer indefinitely. Even so, a few hours of wear every day is a small price to pay to protect your beautiful straightened smile.

Kill Bill fans have been pressing for a third installment of the stylized revenge tale since Kill Bill, Volume 2 hit the theaters in 2004. Finally, filmmaker Quentin Tarantino is talking about the long-awaited Volume 3 as if it might soon become a reality. The third movie in the franchise would most likely focus on the now-grown daughter of the character played by Vivica A. Fox in the first two. Vivica recently made known that should Kill Bill, Volume 3 go into production, she thinks 24-year-old actress and singer Zendaya would be perfect for the role.
Although Zendaya is a few inches taller than Vivica, the two women have a few things in common. Besides being talented movie and television actresses who have won awards for their roles, they both have camera-ready smiles. And both Vivica and Zendaya can thank their dentists for helping their smiles be their best.
In 2016, Vivica told Dear Doctor magazine that her smile needed a boost, so she opted for dental veneers to correct gaps between her teeth—and she's very happy with them. “I love my veneers!” she exclaimed. Zendaya also had help in achieving her Hollywood-perfect smile. In 2011, early in her career on the Disney channel, she wore clear orthodontic aligners to straighten her teeth. To further perfect her smile, she visited her dentist for professional teeth whitening in 2016, inviting a film crew along to show how easy and effective in-office tooth whitening is.
But you don't have to be a celebrity to enjoy smile-enhancing dental treatments. They are great options for anyone who wants to improve the look of their smile.
Teeth whitening. If your teeth are looking yellowed, in-office whitening can make them up to 10 shades brighter in one visit! Some people prefer professional at-home whitening kits, which produce great results more gradually.
Bonding or veneers. For small chips and cracks, cosmetic bonding can cover flaws by adding layers of a tooth-colored material over the tooth. For bigger flaws, heavy discoloration or gaps between teeth as Vivica had, dental veneers may be the answer. These custom-made thin porcelain shells cover the front-facing surface of the tooth, hiding imperfections to give anyone a Hollywood smile.
Orthodontics. Crooked teeth can detract from the look of a smile. While traditional braces are an option, many people with mild to moderate alignment issues find removable clear aligners the perfect way to get the smile they desire with minimal impact on their daily activities. Clear aligners are very subtle and can be removed for eating and cleaning as well as for special occasions—or for filming scenes, as Zendaya knows.
