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 you would like more information on RPDs, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Removable Partial Dentures.”
Most of us have no clue how the ancient holiday tradition of kissing under the mistletoe originated—but it sure doesn't stop us from keeping the tradition alive! Yet although eager to join a certain someone under the hanging twig, you still might hesitate to apply the old smackeroo out of fear your breath isn't as fresh as it should be.
Bad breath has tormented us humans long before we started osculating (kissing) under trimmings of viscum album (the scientific name for mistletoe). Our resulting discomfort has inspired a myriad of remedies, from ancient Egyptian toothpastes containing natron (also used in embalming mummies) to 19th Century American breath mints made of ingredients like cardamom, essence of rose and licorice root.
Today, we're much better at relieving common bad breath because we've uncovered its primary source: bits of food and mucus accompanied by oral bacteria on undisturbed areas the mouth, particularly the tongue. As the debris interacts with the bacteria, it releases chemical compounds called VSCs (volatile sulfur compounds) that emit a classic rotten egg smell.
The key then is to remove the source of these VSCs. You might think that means doing a better job of brushing and flossing, and you're right. But it can involve more.
Keeping your tongue clean. Since the tongue is a prime collecting point for debris and bacteria, it makes sense to keep it clean. That might simply mean brushing its surface when you brush your teeth. You might, however, benefit from using a tongue scraper if you have more stubborn accumulations.
Maintaining your dentures. These and other dental appliances can accumulate food debris that if not removed can cause a “stink.” You should clean dentures daily using a denture cleaner or mild antibacterial soap and then rinse them off thoroughly. It also helps to take them out at bedtime.
Seeking dental care. Another source of bad breath could be tooth decay or gum disease, or even older dental work in need of repair. Treating these and other conditions (like an oral yeast infection) not only improves your dental health, it could do wonders for your breath.
There are also other sources of foul breath unrelated to the mouth—and some can be serious diseases like diabetes, cancer or lung infections. If your chronic bad breath doesn't respond to your hygiene efforts, it's a good idea to get checked medically.
Now as to holiday traditions, we can't help you maneuver your prospective sweetheart under the mistletoe with you—you're on your own, pal (or gal). But by following these tips for sound oral care, we're sure you'll have the “fresh breath” confidence to follow through from there.
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.
