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.

Boston Bruins defenseman Zdeno Chara had a rough Stanley Cup final against the St. Louis Blues this past June. Not only did the Bruins ultimately lose the championship, but Chara took a deflected puck shot to the face in Game Four that broke his jaw.
With the NHL season now over, the 42-year-old Bruins captain continues to mend from his injury that required extensive treatment. His experience highlights how jaw fractures and related dental damage are an unfortunate hazard in hockey—not only for pros like Chara, but also for an estimated half million U.S. amateurs, many in youth leagues.
Ice hockey isn't the only sport with this injury potential: Basketball, football (now gearing up with summer training) and even baseball players are also at risk. That's why appropriate protective gear like helmets and face shields are key to preventing injury.
For any contact sport, that protection should also include a mouthguard to absorb hard contact forces that could damage the mouth, teeth and gums. The best guards (and the most comfortable fit) are custom-made by a dentist based on impressions made of the individual's mouth.
But even with adequate protection, an injury can still happen. Here's what you should do if your child has an injury to their jaw, mouth or teeth.
Recognize signs of a broken jaw. A broken jaw can result in severe pain, swelling, difficulty speaking, numbness in the chin or lower lip or the teeth not seeming to fit together properly. You may also notice bleeding in the mouth, as well as bruising under the tongue or a cut in the ear canal resulting from jawbone movement during the fracture. Get immediate medical attention if you notice any of these signs.
Take quick action for a knocked-out tooth. A tooth knocked completely out of its socket is a severe dental injury. But you may be able to ultimately save the tooth by promptly taking the following steps: (1) find the tooth and pick it up without touching the root end, (2) rinse it off, (3) place it back in its socket with firm pressure, and (4) see a dentist as soon as possible.
Seek dental care. Besides the injuries already mentioned, you should also see a dentist for any moderate to severe trauma to the mouth, teeth and gums. Leading the list: any injury that results in tooth chipping, looseness or movement out of alignment.
Even a top athlete like Zdeno Chara isn't immune to injury. Take steps then to protect your amateur athlete from a dental or facial injury.

Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.
Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.
While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.
But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.
Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.
There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.
The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.
While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.
