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.

Ever since childhood, when her career as a model and actress took off, Brooke Shields has enjoyed worldwide recognition — through advertisements for designer jeans, appearances on The Muppet Show, and starring roles in big-screen films. But not long ago, that familiar face was spotted in an unusual place: wearing a nasal anesthesia mask at the dentist's office. In fact, Shields posted the photo to her own Instagram account, with the caption “More dental surgery! I grind my teeth!” And judging by the number of comments the post received, she's far from alone.
In fact, researchers estimate that around one in ten adults have dental issues that stem from teeth grinding, which is also called bruxism. (Many children also grind their teeth, but it rarely causes serious problems, and is often outgrown.) About half of the people who are teeth grinders report problems like persistent headaches, jaw tenderness and sore teeth. Bruxism may also result in excessive tooth wear, and may damage dental work like crowns and bridges; in severe cases, loosened or fractured teeth have been reported.
Researchers have been studying teeth grinding for many years; their findings seem to indicate that it has no single cause. However, there are a number of factors that play a significant role in this condition. One is the anatomy of the jaw itself, and the effect of worn or misaligned teeth on the bite. Another factor relates to changes in brain activity that occur during the sleep cycle. In fact, nocturnal (nighttime) bruxism is now classified as a sleep-related movement disorder. Still other factors, such as the use of tobacco, alcohol and drugs, and a high level of stress or anxiety, can make an individual more likely to experience bruxism.
What can be done for people whose teeth grinding is causing problems? Since this condition may have many causes, a number of different treatments are available. Successful management of bruxism often begins by striving to eliminate the factors that may cause problems — for example, making lifestyle changes to improve your health, creating a soothing nighttime environment, and trying stress-reduction techniques; these may include anything from warm baths and soft music at bedtime, to meditation and mindfulness exercises.
Several dental treatments are also available, including a custom-made occlusal guard (night guard) that can keep your teeth from being damaged by grinding. In some cases, a bite adjustment may also be recommended: In this procedure, a small amount of enamel is removed from a tooth to change the way it contacts the opposite tooth, thereby lessening the biting force on it. More invasive techniques (such as surgery) are rarely needed.
A little tooth grinding once in a while can be a normal response to stress; in fact, becoming aware of the condition is often the first step to controlling it. But if you begin to notice issues that could stem from bruxism — or if the loud grinding sounds cause problems for your sleeping partner — it may be time to contact us or schedule an appointment.

If you’re seeing your dentist regularly, that’s great. But if that’s all you’re doing to stay ahead of dental disease, it’s not enough. In fact, what you do daily to care for your teeth is often the primary factor in whether or not you’ll maintain a healthy mouth.
Top of your oral care to-do list, of course, is removing daily plaque buildup from teeth and gums. This sticky film of bacteria and food particles can cause both tooth decay and periodontal (gum) disease. You do that with effective daily brushing and flossing.
Effective brushing starts with the right toothbrush—for most people a soft-bristled, multi-tufted brush—and fluoride toothpaste. As to technique, you should first avoid brushing too hard or too often (more than twice a day). This can damage your gums and cause them to recede, exposing the tooth roots to disease. Instead, use a gentle, scrubbing motion, being sure to thoroughly brush all tooth surfaces from the gumline to the top of the teeth, which usually takes about two minutes.
The other essential hygiene task, flossing, isn’t high on many people’s “favorite things to do list” due to frequent difficulties manipulating the floss. Your dentist can help you with technique, but if it still proves too difficult try some different tools: a floss threader to make it easier to pull floss through your teeth; or a water flosser, a handheld device that directs a pressurized water stream on tooth and gum surfaces to loosen and flush away plaque.
And don’t forget other tooth-friendly practices like avoiding sugary snacks between meals, drinking plenty of water to avoid dry mouth, and even waiting to brush or floss about an hour after eating. The latter is important because acid levels rise during eating and can temporarily soften enamel. The enzymes in saliva, though, can neutralize the acid and re-mineralize the enamel in about thirty minutes to an hour. Waiting to brush gives saliva a chance to do its job.
Lastly, keep alert for anything out of the ordinary: sores, lumps, spots on the teeth or reddened, swollen, bleeding gums. All these are potential signs of disease. The sooner you have them checked the better your chances of maintaining a healthy mouth.
