Before implants, people often turned to a removable appliance to replace multiple missing teeth. Known as a removable partial denture (RPD), this appliance could restore both appearance and function at an affordable price.
But although implants may have diminished their use, RPDs haven't gone extinct. They're still a viable option for patients who can't afford implants or fixed bridgework, or who can't obtain implants due to the state of their dental health.
Although replacing only a few teeth rather than an entire arch, RPDs are similar in basic concept to full dentures. The prosthetic (artificial) teeth are anchored in a resin or plastic that's colored to resemble the gums, precisely placed to fit into the missing gaps. This assembly is further supported by a frame made of vitallium, a lightweight but strong metal alloy. The appliance fits upon the arch with the missing teeth, supported by vitallium clasps that grip adjacent natural teeth.
Each RPD must be custom designed for each patient to fit perfectly without excessive movement during chewing. Too much movement could warp the fit, reduce the RPD's durability or damage other teeth. To achieve this secure fit, dentists must take into account the number and location of missing teeth to be replaced, and then apply a specific construction pattern to balance the appliance.
There are RPDs that are meant to be used short-term, as with a teenager whose jaw isn't yet mature for dental implants. But the metal-framed RPDs we've described are designed for long-term use. There is, however, one primary downside: RPDs have a propensity to collect dental plaque, a thin biofilm most responsible for dental disease that could further deteriorate your dental health.
To avoid this, you'll need to keep both the RPD and the rest of your teeth and gums as clean as possible with daily brushing and flossing, and appliance care. And like dentures, it's best to remove the RPD when you go to bed at night to discourage the growth of harmful bacteria.
To see if an RPD to replace your missing teeth is an option for you, visit us for a complete dental exam. From there, we can advise you further as to whether an RPD could affordably restore your missing teeth and your smile.

What happens when you lose a tooth? In the short-run, it can certainly undermine your appearance and ability to efficiently chew and digest food. But a chain of events could also be set in motion that may cause the most harm to your appearance and health—and it all has to do with bone loss.
Our bones aren't just rigid structures providing a frame for our bodies. They're living tissue with other purposes like producing blood cells and regulating the endocrine system. Bone tissue is constantly replenishing itself as older cells die and newer ones take their place.
In the jawbone, the pressure generated by the teeth while biting and chewing travels through the roots to stimulate the growth of new bone. If a tooth goes missing, however, the bone around the tooth also loses this growth stimulus.
This can cause normal bone growth to slow so that dying bone cells aren't sufficiently replaced. The bone may then diminish at an alarming rate—a decrease in width of about 25% in the first year after a tooth loss and several millimeters in height after only a few years.
This bone loss can continue to advance, especially if multiple teeth are lost, until the jaw structure as a whole loses significant height. The bite may then collapse, forcing the front teeth to push forward. In this state, a person may not be able to adequately bite or chew food. It can also damage their appearance—their smile suffers, of course, but their entire face may also appear shrunken.
You may be able to avoid this scenario if you replace missing teeth with dental implants. In addition to their life-likeness and durability, implants can also stop or slow bone loss. This is because titanium, the principle metal used in an implant, has a strong affinity with bone: Bone cells readily grow and attach to the titanium surface and foster new growth.
But don't wait: Bone loss could eventually extend beyond what an implant can accommodate—you may then need grafting to build up the bone or consider a different type of restoration. So, speak with your dentist as soon as possible about an implant restoration for a lost tooth to help avoid significant bone loss.

One in ten Americans has diabetes, a serious condition that may increase the development and severity of other health problems—including gum disease. Because of this latter connection, dental providers join other health professionals during November's National Diabetes Month to call attention to this chronic disease and its effect on health and well-being.
There's another health condition with a diabetes connection that isn't as well known: obstructive sleep apnea (OSA). It's also of keen interest to dental providers, as dentists are often involved in the discovery and treatment of this common sleep disorder.
OSA is the temporary blockage of the airway during sleep by the tongue or other anatomical structures. The subsequent drop in oxygen awakens the body to remove the obstruction. People with OSA may not realize they have the condition, but their bed partner can often attest to their snoring, snorting and gasping for breath during the night. Such episodes can occur several times per night, depriving the person of sufficient sleep.
Chronic OSA can contribute to the development of other health problems, among them Type 2 diabetes. It can do this first by interfering with the metabolization of glucose (blood sugar). It may also increase the body's resistance to insulin, the primary hormone regulating glucose.
Fortunately, properly managing OSA can lower your risk for diabetes, and that's where dentists may be able to help. For one thing, we dentists are often the first to notice early signs of OSA—sometimes even before our patients do.
According to the American Sleep Apnea Association, as many as 80% of the estimated 22 million Americans with OSA may not know they have it. But dentists often identify OSA indicators while examining patients: signs like an enlarged tongue or tonsils, or patients falling asleep in the exam chair. While we can't formally diagnose OSA, we often refer symptomatic patients to a sleep specialist.
Dentists also offer an alternative to the most common OSA therapy, which is continuous positive airway pressure (CPAP). This therapy employs a motorized pump that delivers pressurized air into the throat via face mask to keep the airway open during sleep. Although effective, some people find a CPAP machine noisy and uncomfortable to use.
Alternatively, dentists can provide an oral device that can often help patients with mild to moderate OSA that's worn in the mouth during sleep. Most of the various types of these appliances either reposition the lower jaw with a hinge mechanism to keep the throat open or pull the tongue away from the airway through a suction effect.
Diabetes is one part of a chain reaction that can bring unexpected challenges to your health, including to your teeth and gums. You can slow or even stop its development with proper diet, exercise and good, restful sleep. Dealing with OSA is often part of that equation—and we may be able to help.

We all want to look young and vibrant, or at least “age gracefully.” If you're seeking to reduce the visible effects of aging for a more youthful appearance, be sure you include one very important feature—your smile.
Like other aspects of body and health, our teeth and gums can be affected by aging. Even if you've managed for the most part to avoid the ravages of disease or injury, teeth will still naturally wear from a lifetime of biting and chewing food. The attractive shine of young teeth can also give way to yellowing and other discolorations later in life.
But there are ways to turn back the clock, so to speak, through cosmetic dentistry. And you won't necessarily break the bank to gain a more youthful smile: Many cosmetic procedures are quite affordable and minimally invasive.
If your teeth have become worn and edgy, for example, we may be able to soften those sharper edges with a dental drill. Known as enamel contouring (or reshaping), the single-visit procedure is relatively minor and inexpensive, usually without the need for anesthesia. For heavily worn teeth, you may need to step up to veneers, thin layers of tooth-colored porcelain, or crowns that cover the teeth and make them appear longer.
Mild enamel yellowing and staining often responds well to professional teeth whitening. Using a safe bleaching solution, we can temporarily restore brightness to your teeth that you may be able to maintain for a few years with proper care and occasional touchups. For a more permanent solution you can also turn to veneers, crowns or dental bonding for a brighter smile, especially for discolorations that don't respond well to teeth whitening.
While these techniques can restore a youthful appearance to your smile, don't discount the effect of daily care and regular dental visits. Brushing and flossing are fundamental to healthy teeth and gums—and health and beauty go hand in hand.
Age can take its toll on all of us, especially our smiles. But with proper care and perhaps a little cosmetic magic, you can have an attractive smile throughout your lifetime.

Although energy drinks are but a blip on the historical timeline compared to coffee or tea, they've displaced these traditional stimulants among nearly half of today's adolescents and young adults. But these sweetened “processed” drinks are also controversial among healthcare experts—particularly the effect they may have on dental health.
Besides the added sugar found in many energy drinks—a prime food source for harmful bacteria—many energy drinks and their cousins sports drinks contain significant amounts of acid. High levels of acid soften and erode tooth enamel, which can lead to tooth decay.
During one experimental study, portions of tooth enamel were subjected to a number of name-brand energy and sports beverages. Over the course of a few days, researchers recorded significant enamel loss, especially involving the energy drink samples.
Abstaining from both energy and sports drinks is a sound way to avoid enamel erosion (the best hydrator, it turns out, is simply water). But if you do wish to continue consuming these beverages, here are a few common sense precautions for reduce the risk of harm to your teeth.
Partake only at mealtimes. Among its many abilities, saliva is able to neutralize oral acid and bring the mouth to a neutral pH level within 30 minutes to an hour. But if you're sipping on high-acid beverages throughout the day, your saliva may not be able to compensate effectively. Drinking energy drinks only during a meal helps saliva do its acid-buffering job better.
Rinse with water afterwards. Rinsing with a little water after eating or drinking something acidic can help reduce the pH levels in the mouth. That's because water is by and large neutral on the acidic/alkaline scale. Because it's not adding more, rinsing with water dilutes any concentrations of acid that may still be lingering in your mouth.
Don't brush immediately. Brushing is essential to overall hygiene, but if you do it right after you eat or drink, you could be doing more harm than good. That's because elevated acid levels that naturally occur after consuming foods and beverages can temporarily soften and demineralize the surface enamel. Brushing could remove microscopic bits of softened enamel. If you wait an hour to brush, you'll be giving saliva time to “re-mineralize” your enamel.
