When you hear the word “dentures” you probably think of an appliance that replaces all the teeth on a dental arch. But there is another type: a removable partial denture (RPD), which can be a viable option for replacing a few missing teeth.
An RPD rests on the bony gum ridges that once held the missing teeth and are secured with clasps or other attachments to adjacent teeth. While lightweight, RPDs are designed to last for many years — they’re made of vitallium, a light but very strong metal alloy that reduces the RPD’s thickness. Recently, metal-free partial dentures are being used that don’t have the fit or longevity of the vitallium partial dentures, but are considered more of a cosmetic solution.
RPDs are custom-made for each individual patient to accommodate the number, location and distribution of teeth missing throughout the mouth. Their design must also reflect the health and stability of the gums and remaining natural teeth to ensure they won’t move unduly during normal mouth function, and will be as lifelike and unnoticeable as possible.
RPDs have been a mainstay in dentistry for many years and represent a less expensive tooth replacement option than implants or fixed bridgework. But they do have their downsides: because of their method of attachment to the remaining natural teeth they tend to accumulate plaque, which increases the risk of both periodontal (gum) disease and tooth decay. Their fit requires that they attach to the adjacent teeth that will cause some damage and lead to their looseness over time.
If you wear an RPD, there are some things you can do to decrease these problems. First and foremost, you should clean your RPD thoroughly every day, as well as brush and floss your remaining teeth to reduce plaque buildup especially at contact points. Be sure to remove the RPD at night while you sleep. And keep up regular dental visits not only for additional plaque removal but also to allow us to inspect the RPD for problems or wear.
An RPD is a viable option for improving mouth function and restoring your smile after multiple tooth loss. With proper care and maintenance, your RPD can serve you well for many years to come.

Fans of the primetime TV show The Middle were delighted to see that high school senior Sue, played by Eden Sher, finally got her braces off at the start of Season 6. But since this popular sitcom wouldn’t be complete without some slapstick comedy, this happy event is not without its trials and tribulations: The episode ends with Sue’s whole family diving into a dumpster in search of the teen’s lost retainer. Sue finds it in the garbage and immediately pops it in her mouth. But wait — it doesn’t fit, it’s not even hers!
If you think this scenario is far-fetched, guess again. OK, maybe the part about Sue not washing the retainer upon reclaiming it was just a gag (literally and figuratively), but lost retainers are all too common. Unfortunately, they’re also expensive to replace — so they need to be handled with care. What’s the best way to do that? Retainers should be brushed daily with a soft toothbrush and liquid soap (dish soap works well), and then placed immediately back in your mouth or into the case that came with the retainer. When you are eating a meal at a restaurant, do not wrap your retainer in a napkin and leave it on the table — this is a great way to lose it! Instead, take the case with you, and keep the retainer in it while you’re eating. When you get home, brush your teeth and then put the retainer back in your mouth.
If you do lose your retainer though, let us know right away. Retention is the last step of your orthodontic treatment, and it’s extremely important. You’ve worked hard to get a beautiful smile, and no one wants to see that effort wasted. Yet if you neglect to wear your retainer as instructed, your teeth are likely to shift out of position. Why does this happen?
As you’ve seen firsthand, teeth aren’t rigidly fixed in the jaw — they can be moved in response to light and continuous force. That’s what orthodontic appliances do: apply the right amount of force in a carefully controlled manner. But there are other forces at work on your teeth that can move them in less predictable ways. For example, normal biting and chewing can, over time, cause your teeth to shift position. To get teeth to stay where they’ve been moved orthodontically, new bone needs to form around them and anchor them where they are. That will happen over time, but only if they are held in place with a retainer. That’s why it is so important to wear yours as directed — and notify us immediately if it gets lost.
And if ever you do have to dig your retainer out of a dumpster… be sure to wash it before putting in in your mouth!
