If you have a few missing teeth but can't afford dental implants or fixed bridgework, consider a removal partial denture (RPD). Although implants may be the superior choice aesthetically and functionally, an RPD can still effectively give you back your teeth.
RPDs are designed to replace one or more missing teeth but not a full arch like a full denture. Considered a permanent restoration, RPDs are also more durable than transitional "flippers," denture appliances that are flexible and light enough to be flipped out of the mouth with a flick of the tongue.
The key to both their affordability and durability is vitallium, a strong but lightweight metal alloy most often used in their frame construction. To it we attach artificial teeth usually made of porcelain or glass-filled resins that occupy the precise location of the missing teeth on the gum ridge. The artificial teeth and frame are surrounded by gum-colored plastic for a more natural look.
Each RPD is custom-made depending on the number and location of the missing teeth. Its construction will focus on minimizing any rocking movement of the RPD during chewing or biting. Too much of this movement could damage the adjacent teeth it's attaching to and cause the appliance to be uncomfortable to wear. We can stabilize the frame by precisely fitting it between teeth to buttress it. We also insert small rests or clasps made of vitallium at strategic points to grip teeth and minimize movement.
RPDs do have some downsides: their unique attachment with teeth encourages the accumulation of dental plaque, the thin bacterial film that's the leading cause of tooth decay and periodontal (gum) disease. These diseases can affect your remaining teeth's health and stability, which could in turn disrupt the fit of the RPD. Also, too much movement of the appliance can make the teeth to which it's attached become more mobile. It's important, then, if you wear a RPD to remove it daily for cleaning (and to thoroughly brush and floss your natural teeth), and to remove it at night to give the attaching teeth a rest.
A RPD can give you back the teeth you've lost for many years to come—if you take care of it. Maintaining both your RPD and the rest of your teeth and gums will help extend the life and use of this effective and affordable replacement restoration.

Tooth loss is a problem that affects many seniors—and since May is Older Americans Month, this is a good time to talk about it. Did you know that more than a quarter of adults over age 75 have lost all of their natural teeth? This not only affects their quality of life but poses a significant health risk.
According to a study in The Journal of Prosthodontics, significant tooth loss is associated with increased risk for malnutrition—and also for obesity. If this seems like a contradiction, consider that when you have few or no teeth, it’s much easier to eat soft, starchy foods of little nutritional value than it is to eat nutritious fresh fruits and vegetables. If all of your teeth are missing, it’s especially critical to replace them as soon as possible.
There are several ways to replace a full set of missing teeth, including removable dentures, overdentures, and fixed dentures:
Removable dentures are the classic replacement teeth that you put in during the day and take out at night. (However, if you suffer from sleep apnea, research has found that keeping dentures in at night may help keep the airway open, so if you have this condition, be sure to mention it to your doctor and dentist it). Dentures have come a long way in terms of how convincing they look, but they still have some disadvantages: For one thing, they take some getting used to—particularly while eating. Also, wearing removable dentures can slowly wear away the bone that they rest on. As that bone gradually shrinks over time, the dentures cease to fit well and require periodic adjustment (re-lining) or a remake.
Overdentures are removable dentures that attach onto a few strategically placed dental implants, which are small titanium posts placed in the bone beneath your gums. Strong and secure, implants prevent the denture from slipping when you wear it. Implants also slow the rate of bone loss mentioned above, which should allow the denture to fit better over a longer period of time. The ability to maintain hygiene is easier because you can remove them for cleaning.
Fixed implant-supported dentures are designed to stay in your mouth all the time, and are the closest thing to having your natural teeth back. An entire row of fixed (non-removable) replacement teeth can usually be held in place by 4-6 dental implants. Dental implant surgery is an in-office procedure performed with the type of anesthesia that’s right for you. After implants have been placed and have integrated with your jaw bone—generally after a few months—you can enjoy all of your favorite foods again without worry or embarrassment.

Today's dental restorations are truly amazing. Not only are they life-like and functional, they can endure for many years a hostile environment of bacteria, acid and heavy biting forces.
Even so, you'll still need to take care of your restorations to help them last. Here's how to extend the life of 3 common forms of dental work.
Fillings. We use fillings, both metal amalgam and tooth-colored materials, to repair holes or cavities in teeth caused by tooth decay. Although strong, dental fillings can break if you subject them to abnormally high biting force (like chewing ice). There's also a chance that if a slight separation occurs between the filling and tooth, bacteria can take up residence and reignite the decay process. To prevent this, practice a daily regimen of oral hygiene to clean away bacterial plaque—and reduce sugar in your diet, a prime food source for bacteria.
Veneers. Usually made of thin porcelain, veneers are bonded to the front of teeth to mask chips, stains, gaps or other blemishes. But although they're strong, veneers aren't immune to damage. Habits like biting nails, the aforementioned ice chewing or unconsciously grinding your teeth could cause a chipped veneer. And if periodontal (gum) disease causes your gums to recede, the exposed part of the tooth may look noticeably darker than the veneer. To protect your veneers and their appearance, avoid habits like ice chewing, and seek treatment for teeth grinding and dental disease.
Bridgework. Bridges are used to replace one or more missing teeth. Traditional bridges use the natural teeth on either side of the gap to support the bridge; for a single missing tooth, implants are a preferable option because they don't require permanently altering the neighboring teeth to support it. With either option, though, you should brush and floss around the restoration to reduce the risk of dental disease. Infections like gum disease or tooth decay could eventually weaken the bridge's supporting teeth or gum disease can damage an implant's gum and bone support.
With any dental restoration, be sure to practice daily oral hygiene, eat a nutritious, low-sugar diet, and see your dentist regularly for cleanings and checkups. Taking care of your dental work will help it take care of you for a long time to come.
