People with missing teeth have more replacement options than ever before, including the ever popular but often more expensive dental implant. But there has also been an expansion of choice on the more affordable side of dental restorations. The flexible removable partial denture (RPD) is one such choice.
Though RPDs have been around for some time, the newer flexible RPD offers some advantages over the more rigid traditional RPD. They’re made of a kind of nylon that’s pliable but also strong and durable. This material is thermoplastic, meaning when heated it can be injected into molds based on a patient’s individual mouth to form an accurate denture base. The gum-colored base can also be formed to cover any receded areas of the gums, which can greatly improve smile appearance.
Older versions of RPDs are made of rigid acrylic plastic that stay in place in the mouth with metal clasps that attach to remaining teeth. The flexible RPD, on the other hand, is secured with finger-like nylon extensions that fit and hold in the natural teeth’s concavities near the gum line. This, along with its relatively light weight, offers a more comfortable fit.
But aside from these benefits, flexible RPDs do have a few drawbacks. Although fracture-resistant, they’re not easy to repair or reline to readjust the fit to accommodate mouth changes. They can stain (though not as much as a traditional RPD), so they require diligent cleaning and maintenance.
We consider the whole category of RPDs as “temporary” restorations, meaning they’re intended as a transitional phase between tooth loss and a permanent restoration like a natural tooth-supported fixed bridge or dental implants. For some, however, the flexible RPD might be a more long-term solution. As mentioned before, to extend their life as much as possible they should be removed daily and cleaned thoroughly. And like any form of denture, they should not be worn overnight.
In either case, flexible RPDs offer an effective way to restore not only dental function diminished by missing teeth but an improved appearance as well. With careful maintenance, they could serve you well for some time to come.

Academy Award-winning actress Kathy Bates knows how important it is to present your best face to the world — and one of the most important features of that face is a beaming smile. But there came a point when she noticed something was a little off. “I've always had good teeth, but it seemed to me as I was getting older that they weren't looking as good,” Kathy explained in a recent interview with Dear Doctor magazine.
That's when she decided it was time to take action. Kathy had orthodontic treatment when she was in her fifties, and she keeps her smile bright with tooth whitening treatments. She uses a kit provided by her dentist with a safe, effective whitening solution.
Of course, a bright, healthy smile looks great anywhere — whether you're on the red carpet or “off the grid.” And you don't have to be a Hollywood star to have professional whitening treatments. In fact, teeth whitening is one of the most popular and affordable cosmetic treatments modern dentistry offers.
The basic options for professional teeth whitening include in-office bleaching or take-home kits. Both types of dentist-supervised treatments offer a safe and effective means of getting a brighter smile; the main difference is how long they take to produce results. A single one-hour treatment in the office can make your teeth up to ten shades lighter — a big difference! To get that same lightening with at-home trays, it would take several days. On the plus side, the take-home kit is less expensive, and can achieve the same results in a bit more time.
It's important to note that not all teeth can be whitened with these treatments. Some teeth have intrinsic (internal) stains that aren't affected by external agents like bleaches. Also, teeth that have been restored (with bonding or veneers, for example) generally won't change color. And you can't necessarily whiten your teeth to any degree: Every tooth has a maximum whiteness, and adding more bleach won't lighten it beyond that level. Most people, however, find that teeth whitening treatments produce noticeable and pleasing results.
What about those off-the-shelf kits or in-the-mall kiosks? They might work… or they might not. But one thing's for sure: Without a dentist's supervision, you're on your own. That's the main reason why you should go with a pro if you're considering teeth whitening. We not only ensure that your treatment is safe — we can also give you a realistic idea of what results to expect, and we will make sure that other dental problems aren't keeping you from having a great-looking smile.
How often does Kathy Bates see her dentist for a checkup and cleaning? “I go about every four months,” she noted. “I'm pretty careful about it.” And if you've seen her smile, you can tell that it pays off.

Dental implants are today’s closest restorative facsimile to natural teeth. And they’re versatile: not only can they replace single teeth but they can also support bridges or dentures.
But since one of their crucial components is made of metal, are you out of luck obtaining this state-of-the-art dental restoration if you have a metal allergy?
The answer is: probably not—it’s rare for implants to cause an allergic reaction. Still, metal allergies can be a potential problem within your mouth as with other areas of health.
An allergy originates from the body’s necessary response to potentially harmful microorganisms or substances. Sometimes, however, this response becomes chronic and exaggerated, creating an allergy. People can have allergies to nearly anything with responses ranging from a minor rash to a potentially life-threatening multi-organ system shutdown (anaphylactic shock).
A small number of people have allergies to particular metals. One of the most common is nickel, which affects an estimated 17% of women and 3% of men; cobalt and chromium are also known to cause allergies. Consumer exposure, particularly metal contact with the skin through jewelry or clothing, is the most prevalent, but not the most concerning. That’s reserved for metal allergies related to medical devices like coronary stents or hip and knee prostheses. And in dentistry, there are rare occasions of inflammation or rashes from metal amalgam fillings.
Which brings us to dental implants: the main metal post that’s inserted into the jawbone is usually made of titanium. It’s the metal of choice for two reasons: it’s bio-compatible, meaning the body normally accepts its presence; and it’s osteophilic, which means bone cells readily grow and adhere to it, a major reason for implant durability.
While it’s possible for someone to have an allergy and subsequent reaction to implants with titanium, the occurrences appear to be extremely low. In one study of 1,500 patients, titanium allergies were estimated to be a factor in implant failures in less than 1% of those studied.
Even so, if you have known metal allergies you should make sure your dentist knows. Being aware of all the facts will help them recommend the best tooth replacement choice for you—and hopefully it will be dental implants.
