Modern dentistry offers several great ways to permanently replace missing teeth, including high-tech dental implants and traditional fixed bridgework. But sometimes, for one reason or another, it isn’t possible to have these treatments done right away. If you need an aesthetic way to temporarily replace missing teeth, a flexible partial denture could be the answer you’re looking for.
Certain kinds of removable partial dentures (RPDs) can be used as permanent tooth replacement systems, especially for people who aren’t candidates for dental implants or fixed bridges. But in the past, if you needed a temporary tooth replacement, one of the few alternatives was the type of rigid RPD often called a “flipper.” This consists of a firm, relatively thick acrylic base that supports one or more lifelike replacement teeth. It attaches to the “necks” of existing natural teeth via metal clasps, which gives it stability and strength.
However, the same rigidity and thickness that gives these rigid RPDs their durability can make them uncomfortable to wear, while the acrylic material they are made of is capable of staining or breaking. Over time, the RPDs are prone to coming loose — and they are also easy to flip in and out with the tongue, which gives them their nickname.
Flexible partial dentures, by contrast, are made of pliable polyamides (nylon-like plastics) that are thin, light and resistant to breakage. Instead of using metal wires to attach to the teeth, flexible RPDs are held securely in place by thin projections of their gum-colored bases, which fit tightly into the natural contours of the gumline. Their elasticity and light weight can make them more comfortable to wear. Plus, besides offering aesthetic replacements for missing teeth, their natural-looking bases can cover areas where gums have receded — making existing teeth look better as well.
All RPDs must be removed regularly for thorough cleaning — but it’s especially important for flexible RPD wearers to practice excellent oral hygiene. That’s because the projections that hold them in place can also trap food particles and bacteria, which can cause decay. And, like most dentures, RPDs should never be worn overnight. Yet with proper care, flexible RPDs offer an inexpensive and aesthetic way to temporarily replace missing teeth.
Nearly half of all Americans have some form of periodontal (gum) disease. Without proper daily hygiene and treatment, this aggressive disease can ultimately cause tooth loss. It also appears the effects of gum disease reach beyond the mouth, as researchers have found relationships between it and other systemic diseases.
Inflammation, the body’s response to infection, is at the center of these relationships. In the case of gum disease, periodontal tissues become inflamed as the body attempts to isolate and fight the infection. If the inflammation becomes chronic, however, it will begin to damage gum tissues.
Inflammation is also a major feature of diabetes, a condition in which the pancreas doesn’t produce enough insulin. Without enough of this hormone that transforms sugar into usable energy for the body, the sugar accumulates in the blood stream; as a result, the patient becomes more susceptible to an exaggerated inflammatory response when the body encounters an infection. This is especially true for periodontal infections: the resulting inflammation can be greater and harder to control in diabetic patients. What’s more, uncontrolled gum disease may worsen their blood sugar levels.
Although not as prominent as with diabetes, cardiovascular disease also seems to share a connection with gum disease. This collection of chronic conditions like high blood pressure or restricted blood vessel flow raises the risk of heart attack or stroke. Like gum disease, inflammation is a major component in the progression of cardiovascular disease — in fact, both diseases leave similar chemical “markers” in the blood that indicate their early development.
Ongoing research has also produced some promising treatment findings for both gum disease and inflammatory diseases, which also include osteoporosis, respiratory disease and rheumatoid arthritis. We’re now finding in many cases that treating one side of the disease connection can have positive effects on the other side. For example, diabetics who receive professional treatment for gum disease may see better blood sugar control.
With this in mind, the best approach is to practice effective, daily oral hygiene to reduce the risk of gum disease, coupled with regular office cleanings and checkups. Not only will this help you maintain optimum oral health, it may also contribute to better management of other conditions you may have.

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.
