Dentures in one form or another have been around for centuries. Although dental implants have earned a well-deserved prominence of late, the denture still remains a viable tooth replacement option.
What's more, dentures aren't reserved for total tooth loss only. Even if you've lost just a few of your teeth, we can fit you with a removable partial denture (RPD). Although mainly considered a temporary solution for missing teeth, some people depend on an RPD for many years due to finances or other issues.
The traditional RPD consists of a rigid acrylic plastic base that resembles gum tissue supported by a metal framework, with prosthetic (false) teeth precisely placed to fill the space of the missing teeth. They're held in place with metal clasps that extend from the metal framework to fit over the remaining natural teeth.
Although they're an effective restoration, traditional RPDs have a few drawbacks. Some people find them uncomfortable to wear or have an allergy to the acrylic plastic. They also have a propensity to stain from beverages like tea, coffee or wine.
But there's a more recent version called a flexible RPD that addresses these and other concerns. It's made of a pliable nylon that's durable, yet comfortable to wear. Rather than metal clasps, they're secured in place with thin, finger-like nylon extensions that fit into the small, natural depressions in the crowns of the teeth around the gum line.
Flexible RPDs are also highly adaptable to appear life-like in many situations. We can fashion the nylon base to cover areas around natural teeth where the gums may have receded due to gum disease.
They do, however, have a few downsides. Unlike traditional dentures, they're difficult to reline or repair. Like any oral appliance, they can suffer from wear and neglect, so you must properly clean and maintain them. And, like any RPD their best role is as a temporary bridge rather than a permanent restoration.
In the meantime, though, you can count on a flexible RPD to restore your ability to eat and speak proficiently, as well as smile with confidence. It's a great affordable way to address a few missing teeth.

A loose baby tooth is normal and expected; a loose permanent tooth is quite another matter: it’s an advanced sign of disease that could lead to losing the tooth.
The reasons for its looseness may vary. You may have experienced “primary occlusal trauma,” in which the teeth have experienced a prolonged excessive biting force beyond their tolerance. This can be caused by habitual grinding or clenching the teeth.
You may have also experienced “secondary occlusal trauma”: although the biting forces are within normal ranges, the teeth still can’t handle the stress due to degraded bone support and gum tissue detachment. Clenching habits combined with weakened bone and gums will only accelerate and worsen the damage.
The most frequent cause in adults for loose teeth is secondary trauma from periodontal (gum) disease. Bacterial plaque built up on teeth from poor oral hygiene causes a chronic infection that eventually weakens gum attachment to the teeth. A loose tooth is a late sign of this damage.
Treatment for disease-based loose teeth has a twofold approach. First, we thoroughly clean the tooth, root and gum surfaces of all plaque and calculus (hardened plaque deposits) to reduce the infection and inflammation and restore tissue health. This is often accompanied by antibiotic treatments to reduce bacteria below the gum tissue.
For the loose teeth themselves, we may need to modify the forces against them while the gums and bone heal. One way to lessen the biting force on a tooth is to reshape its and the opposing tooth’s biting surfaces. For extensive looseness we can also splint the affected tooth or teeth with other teeth. Temporarily, we can apply splinting material to the outside of both the loose and stable teeth or cut a small channel into them and apply bonding material to join them. A permanent option is to crown both the affected teeth and nearby stable teeth and fuse the crowns together.
These and other stabilizing techniques, like occlusal night guards to reduce the effects of teeth grinding or orthodontic treatment, will help secure the teeth. Coupled with disease treatment and renewed dental care and hygiene practices, you may be able to keep that loose tooth from being lost.

For generations, dentures have helped people avoid the dire consequences of total teeth loss. Now, implant technology is making them even better.
Composed of life-like prosthetic teeth fixed within a plastic or resin gum-colored base, dentures are manufactured to fit an individual patient’s mouth for maximum fit, comfort and performance. But dentures also have a critical drawback—they can’t stop bone loss in the jaw.
Bone is constantly regenerating as older cells dissolve and then are replaced by newer cells. In the jawbone, the forces generated when we chew travel through the teeth to the bone and help stimulate this new cell growth. When teeth are missing, though, the bone doesn’t receive this stimulus and may not regenerate at a healthy rate, resulting in gradual bone loss.
Dentures can’t transmit this chewing stimulus to the bone. In fact, the pressure they produce as they rest on top of the gums may actually accelerate bone loss. Over time then, a denture’s once secure and comfortable fit becomes loose.
In the past, most patients with loose dentures have had them relined with new dental material to improve fit, or have new dentures created to conform to the changed contours of the jaws. But implant technology now offers another alternative.
Implants are in essence a tooth root replacement. Dentists surgically implant a titanium metal post directly into the jawbone that naturally attracts bone cells to grow and adhere to it over time (a process called osseointegration). This not only creates a secure and lasting hold, it can also stop or even reverse bone loss.
Most people know implants as single tooth replacements with a porcelain crown attached to the titanium post. But a few strategically placed implants can also support either removable or fixed dentures. Removable dentures (also called overdentures) usually need only 3 or 4 implants on the top jaw and 2 on the bottom jaw for support through built-in connectors in the dentures that attach to the implants. A fixed bridge may require 4-6 implants to which they are permanently attached.
There are pros and cons for each of these options and they’re both more expensive than traditional dentures. In the long run, though, implant-supported dentures could be more beneficial for your bone health and hold their fit longer.
If you think gum disease only happens to the other guy (or gal), think again. If you’re over 30 you have a 50-50 chance for an infection. After 65 the risk climbs to 70 percent.
Fortunately, we can effectively treat most cases of gum disease. But depending on its severity, treatment can involve numerous intensive sessions and possible surgery to bring the disease under control. So, why not prevent gum disease before it happens?
First, though, let’s look at how gum disease most often begins—with dental plaque, a thin film of bacteria and food particles built up on teeth and gum surfaces. If plaque isn’t consistently removed through daily brushing and flossing, it doesn’t take long—just a few days—for the bacteria to infect the gums.
While it’s not always easy to detect gum disease early on, there are signs to look for like red, swollen and tender gums that bleed easily when you brush or floss, and bad breath or taste. The infection is usually more advanced if you notice pus-filled areas around your gums or loose teeth. If you see any of these (especially advanced signs like loose teeth) you should contact us as soon as possible.
Obviously, the name of the game with prevention is stopping plaque buildup, mainly through daily brushing and flossing. Technique is the key to effectiveness, especially with brushing: you should gently but thoroughly scrub all tooth surfaces and around the gum line, coupled with flossing between teeth.
To find out how well you’re doing, you can rub your tongue along your teeth after you brush and floss—you should feel a smooth, almost squeaky sensation. You can also use plaque-disclosing agents that dye bacterial plaque a particular color so you can easily see surface areas you’ve missed. You can also ask us for a “report card” on how well you’re doing during your next dental visit.
Dental visits, of course, are the other essential part of gum disease prevention—at least every six months (or more, if we recommend) for cleaning and checkups. Not only will we be able to remove hard-to-reach plaque and tartar, we’ll also give your gums a thorough assessment. By following this prevention regimen you’ll increase your chances of not becoming a gum disease statistic.
