Oral appliances run the gamut from night guards and retainers to full or partial dentures. Millions of people depend on them for restoring or maintaining dental health.
Today's user-friendly appliances reflect the latest advances in technology. But that doesn't mean you can simply "place them and forget them." Their longevity depends on taking care of them.
The most important aspect of appliance care is keeping them clean. Although bacteria have no effect on an appliance's materials, they can accumulate on its surfaces and raise the risk your natural teeth and gums will be infected. To reduce that risk you should clean your appliance every day.
The best way is with a countertop ultrasonic cleaner. These units emit high frequency sound vibrations that loosen plaque (a thin film of bacteria and food particles) from even the appliance's tiniest crevices. Most units cost between $40 and $60, and pose less of a scratching risk to the appliance's surfaces than manual cleaning.
If you'd prefer to use a brush, there are some dos and don'ts to follow. You can use a cleaner especially designed for your appliance, but less expensive mild dish detergent or hand soap (with an antibacterial agent) will work too. Don't use toothpaste — most contain an abrasive ingredient for removing plaque from enamel that could leave microscopic scratches on your appliance. Use a soft-bristle toothbrush (but not the one you use for your natural teeth) or one designed for your appliance.
While boiling kills bacteria, the high heat can soften and warp the plastic material in an appliance. This could alter how the appliance fits in your mouth, making them loose and uncomfortable to wear. You should also avoid bleach: it can whiten acrylic or nylon designed to mimic the red color of real gum tissue.
Unless we've advised you otherwise, don't wear the appliance around the clock, a practice that raises the chances of bacterial accumulation. And be sure you also brush and floss your natural teeth every day.
Keeping both your mouth and your appliance clean helps ensure the best oral health possible — and that your appliance will last longer.
The CAT scan is a relatively recent technique in dentistry, used to get an image of what’s happening deep within your jaws. You may be wondering what a CAT scan tells us that a conventional x-ray picture does not, and whether it is worth the extra expense to get one. And how does a CAT scan compare with a conventional x-ray in terms of radiation exposure?
CAT stands for “computer assisted tomography.” Often it’s just called a CT scan, for “computerized tomography.” The word “tomography” comes from roots meaning “slice” and “write.” Tomographic techniques take repeated two dimensional pictures, similar to repeatedly slicing through an object, and then assembles them with a computer to produce a three dimensional (3-D) image.
The latest type of CT scan used in dentistry is called CBCT, or Cone Beam Computed Tomography. The Cone Beam refers to a spiral beam of x-rays, which is used to create a series of two dimensional images from which a computer creates a 3-D image. Such an image is of great value in assessing problems and planning treatment.
Here are just a few examples of how a CBCT scan can be used. Orthodontists can see skeletal structures and developing teeth that are still inside the jawbone while planning strategies for directing the teeth in order to arrive at a better bite. Oral surgeons can find impacted or missing teeth, see their locations, and view their proximity to nerves and sinuses, assisting them in planning surgeries. These scans are particularly useful for root canal specialists because they show root canals that are less than a millimeter wide and even reveal accessory canals that may not be visible on conventional x-rays. In cases of sleep disorders such as sleep apnea, a CBCT during sleep can be used to view a person’s airway and how it may be blocked by the tongue and other soft tissues in a person’s throat during sleep.
Compared to background radiation, the amount of radiation delivered in dental x-rays is minimal. A CBCT delivers a dose of radiation that is less than a typical full mouth x-ray series but more than a typical two dimensional panoramic radiograph. Generally CBCT scanners deliver lower doses than medical CT scanners.
With one low-dose CBCT scan, we can get an accurate idea of the internal structure of your bones and teeth and how they are situated in relation to each other. Prior to the availability of such images, many of these relationships had to be discovered in the course of a surgery or other treatment. Thus such a scan can aid greatly in the quality of treatment you will receive.
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.

In recent decades civilization's millennia-long search for clean, safe drinking water has become much easier with modern purification methods. Today, there are few places in the United States without adequate access to potable water. And about three-fourths of the nation's tap water systems add fluoride, credited with helping to reduce tooth decay over the past half century.
But in recent years some have voiced concerns about the safety of tap water and popularizing an alternative: bottled water. Manufacturers of bottled water routinely market their products as safer and healthier than what comes out of your faucet.
But is that true? A few years ago a non-profit consumer organization called the Environmental Working Group (EWG) performed a detailed, comprehensive study of bottled water. Here's some of what they found.
Lack of transparency. It's not always easy to uncover bottled water sources (in some cases, it might actually begin as tap water), how it's processed, or what's in it. That's because unlike water utilities, which are rigorously monitored by the Environmental Protection Agency (EPA), the Food and Drug Administration (FDA) oversees bottled water production with less strenuous guidelines on labeling. Eight out of the top 10 selling brands were less than forthcoming about their water's contents in EWG's investigation.
Higher cost. According to the EPA, the average consumer cost in the last decade for tap water was $2.00 per 1,000 gallons (0.2 cents per gallon). The retail cost for even bulk bottled water is exponentially higher. It can be a costly expenditure for a family to obtain most of their potable water by way of bottled—while still paying for tap water for bathing and other necessities.
Environmental impact. Bottled water is often marketed as the better environmental choice. But bottled water production, packaging and distribution can pose a significant environmental impact. EWG estimated the total production and distribution of bottled water consumes more than 30 million barrels of oil each year. And disposable plastic water bottles have become one of the fastest growing solid waste items at about 4 billion pounds annually.
While there are credible concerns about tap water contaminants, consumers can usually take matters into their own hands with an affordable and effective household filtering system. EWG therefore recommends filtered tap water instead of bottled water for household use.

Mouth injuries in children and teens are more common than you might think: about one out of three boys and one out of four girls will have experienced an injury before they graduate from high school. Besides contact sports, other types of accidents like car crashes or falls are high on the cause list.
Although most dental injuries aren’t considered true emergencies, there are a few where prompt action may mean the difference between ultimately saving or losing a tooth. One such situation is a knocked out tooth.
In the event of a knocked out (or avulsed) tooth, your primary goal is to place the tooth back into the empty socket as quickly as possible. Teeth that have been out of the mouth for less than five minutes have the best chance of reattachment and survival. The first step is to quickly locate the missing tooth.
Once you’ve found it, use only cold, clean water run or poured over the tooth to carefully clean off dirt or debris (no soaps or cleansers). You should also avoid touching the tooth root or scrubbing any part of it. After cleaning it of debris, gently place the tooth back in its socket, then immediately contact us or visit an emergency room. While you’re en route to our office the patient should carefully hold the tooth in place. If the tooth can’t be immediately placed into the socket (the patient is unconscious, for example), then you should place the tooth in a clean container and keep it moist with cold milk, a sterile saline solution or even the patient’s saliva.
Taking these steps increases the chances of a successful re-implantation, although the injury may ultimately affect the tooth’s lifespan. Replanted teeth can suffer from root resorption (where the root tissue dissolves) or a process known as ankylosis in which the tooth fuses directly to the jawbone with no healthy periodontal ligament in between. Either of these conditions can lead to tooth loss.
Still, it’s worthwhile to try to save the tooth, even if for a few more years. Those extra years can help you prepare for a future restoration.
