The traditional way to restore a tooth with an artificial crown takes several weeks and multiple office visits: from tooth preparation and impression molding to crown production by a dental laboratory, followed by adjustments and cementing. Now, there’s an alternative that reduces this process to a fraction of the time, and all from your dentist’s office.
Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) is a digital system that enables dentists to create dental restorations with laboratory-grade materials in minutes rather than weeks. As it continues to innovate, you’ll see more and more dentists investing in the new technology for their patients.
A crown restoration with CAD/CAM begins like any other with decay removal and preparation of the tooth. It diverges, though, from the traditional in how an impression of your teeth and gums is obtained: instead of rubber-like molding materials to create a physical impression, we lightly dust the mouth interior with a reflective powder. Using a scanning wand, the reflective powder allows us to capture multiple, detailed images of your mouth that the CAD/CAM computer transforms into an accurate three-dimensional model.
We use the model to first assess if the tooth has been effectively prepared for a restoration. If so, the design feature of the system will provide us with thousands of tooth forms to choose from to match with your natural teeth. You’ll be able to view the proposed size and shape of the new crown via computer simulation before signing off on the design.
Next is the actual manufacture of the crown that takes place right in the dentist’s office. A pre-formed block of ceramic material is inserted in the milling equipment where, following the pre-determined computer design, the milling heads carve the ceramic block. After milling, we fine-tune the crown surface and apply stains or glazes fired to create a life-like color and texture that matches your natural teeth. We can then adjust the crown in your mouth and permanently affix it to the tooth.
While much of the CAD/CAM system is automated, ultimate success still depends on the dentist’s expertise and artistry. CAD/CAM enhances those skills with greater precision and in much less time than traditional crowns. It’s certainly a growing option for many people to restore the form and function of decayed teeth.

It's September—and that means football season is underway. Whether you're playing, spectating or managing a fantasy team, the action is about to ramp up. Unfortunately, increased “action” also includes injury risk, especially for a player's teeth, mouth and jaws.
Injury prevention is a top priority for all players, whether the pros or the little guys in Pee Wee league. For oral injuries, the single best way to avoid them is by wearing an athletic mouthguard. This soft but durable plastic appliance helps cushion the force of a direct blow to the face or mouth. Wearing one can help prevent tooth and gum damage, as well as lessen the risk for jaw or facial bone fractures.
Mouthguard use is fairly straightforward—a player should wear one anytime there's player-to-player contact. That's not only during game time, but also during practice and informal play. But what's not always straightforward is which type of mouthguard to purchase. That's right: You'll have to decide from among a variety of mouthguards on the market.
Actually, though, most fall into one of two categories: the “Boil and Bite” found in most retail stores with a sports gear department; or the custom mouthguard fashioned by a dentist.
The first are called Boil and Bite because the mouthguard must first be softened with hot water and then placed in the intended wearer's mouth to bite down on in its softened state. When the mouthguard cools and re-hardens, it will retain the bite impression to give it somewhat of an individual fit. These retail guards are relatively inexpensive and reasonably effective in cushioning hard contact, but they can also be on the bulky side and uncomfortable to wear.
In contrast, custom mouthguards are formed from an accurate impression of the wearer's bite taken in the dental office. Because of the individualized fit, we can create a guard with less bulk, greater comfort and, due to their precision, better effectiveness in preventing injury.
A custom guard is more expensive than a retail mouthguard, and younger players may need a new upgrade after a few seasons to accommodate fit changes due to jaw development. But even so, with its higher level of protection and comfort (making it more likely to be worn during play), a custom mouthguard is a worthwhile investment that costs far less than a devastating dental injury.
So, if you or a family member will be hitting the gridiron this fall (or, for that matter, the basketball court or baseball diamond later in the year), be sure you invest in a mouthguard. It's a wise way to ensure this football season will be a happy one.
Since the discovery a century ago of its beneficial effect on tooth enamel, fluoride has become an important part of tooth decay prevention. It's routinely added to toothpaste and other hygiene products, and many water utilities add minute amounts of it to their drinking water supplies. Although there have been questions about its safety, multiple studies over the last few decades have eased those concerns.
Children especially benefit from fluoride during their teeth's developing years. Some children are at high risk for decay, especially an aggressive form known as Early Childhood Caries (ECC). ECC can destroy primary (baby) teeth and cause children to lose them prematurely. This can have an adverse effect on incoming permanent teeth, causing them to erupt in the wrong positions creating a bad bite (malocclusion).
For children at high risk for decay, dentists often recommend applying topical fluoride directly to the teeth as added protection against disease. These concentrations of fluoride are much higher than in toothpaste and remain on the teeth for much longer. Topical applications have been shown not only to reduce the risk of new cavities, but to also stop and reverse early decay.
Children usually receive these applications during an office visit after their regular dental cleaning. There are three different ways to apply it: gel, foam or varnish. To prevent swallowing some of the solution (which could induce vomiting, headache or stomach pain) the dentist will often insert a tray similar to a mouth guard to catch any excess solution. Varnishes and a few gels are actually painted on the teeth.
The American Dental Association has intensely studied the use of topical fluoride and found its application can result in substantial decreases in cavities and lost teeth. They've concluded this benefit far outweighs the side effects from ingesting the solution in children six years and older. With proper precautions and waiting to eat for thirty minutes after an application, the possibility of ingestion can be reduced even further.
While topical fluoride can be effective, it's only one part of a good dental care strategy for your child. Consistent daily brushing and flossing, a nutritious diet low in added sugar, and regular dental visits still remain the backbone of preventive care.
Tara Lipinski loves to smile. And for good reason: The Olympic-gold medalist has enjoyed a spectacular career in ladies' figure skating. Besides also winning gold in the U.S. Nationals and the Grand Prix Final, in 1997 Lipinski became the youngest skater ever to win a World Figure Skating title. Now a sports commentator and television producer, Lipinski still loves to show her smile—and counts it as one of her most important assets. She also knows the importance of protecting her smile with daily hygiene habits and regular dental care.
Our teeth endure a lot over our lifetime. Tough as they are, though, they're still vulnerable to disease, trauma and the effects of aging. To protect them, it's essential that we brush and floss every day to remove bacterial plaque—that thin accumulating film on teeth most responsible for tooth decay and gum disease.
To keep her smile in top shape and reduce her chances of dental disease, Lipinski flosses and brushes daily, the latter at least twice a day. She also uses a tongue scraper, a small handheld device about the size of a toothbrush, to remove odor-causing bacteria and debris from the tongue.
Lipinski is also diligent about visiting the dentist for professional cleanings and checkups at least twice a year because even a dedicated brusher and flosser like her can still miss dental plaque that can then harden into tartar. Dental hygienists have the training and tools to clear away any lingering plaque and tartar that could increase your disease risk. It's also a good time for the dentist to check your teeth and gums for any developing problems.
The high pressure world of competitive figure skating and now her media career may also have contributed to another threat to Lipinski's smile: a teeth-grinding habit. Teeth grinding is the unconscious action—often while asleep—of clenching the jaws together and producing abnormally high biting forces. Often a result of chronic stress, teeth grinding can accelerate tooth wear and damage the gum ligaments attached to teeth. To help minimize these effects, Lipinski's dentist created a custom mouthguard to wear at night. The slick plastic surface of the guard prevents the teeth from generating any damaging biting forces when they clench together.
The importance of an attractive smile isn't unique to celebrities and media stars like Tara Lipinski. A great smile breeds confidence for anyone—and it can enhance your career, family and social relationships. Protect this invaluable asset with daily oral hygiene, regular dental visits and prompt treatment for disease or trauma.
A shingles outbreak can be painful and embarrassing. It could also interfere with many areas of your life—including your dental care.
Known medically as herpes zoster, shingles is a viral form of chicken pox. The virus can lie dormant for many years or decades in people that had chicken pox as a child, breaking out later in life (sometimes repeatedly). It's estimated about a quarter of people who had chicken pox as a child, about 90% of adults, will experience a shingles outbreak.
In the beginning, a person with shingles may notice an itching or burning skin irritation, as well as numbness or sensitivity to touch. In time, a red, crusty rash can develop, usually forming a belted or striped pattern on the torso, head or facial areas. The patterning is caused by the virus's disruption of nerves that serve those parts of the body.
Shingles could impact your dental care because it can be contagious early in an outbreak. As such, it can be transmitted to other people via contact with the rash or through airborne respiratory particles. Dental staff members or other patients who are pregnant, undergoing cancer treatment or with other conditions that compromise their immune systems can develop serious health problems if they contract the virus.
If you have an upcoming appointment, it's best then to let your dentist know you've been diagnosed with shingles. If your treatment involves physical contact that could spread the virus, they may wish to reschedule you until the outbreak clears up.
There are ways to hasten the healing process with antiviral treatments like acyclovir or famciclovir. For best results, these treatments should begin within 3 days of a shingles outbreak. There is also a shingles vaccine that can help you avoid an outbreak altogether. The U.S. Centers for Disease Control (CDC) recommend it for adults over 60.
Having shingles can be painful and stressful, and pose a major interruption of your daily life and routine. With proper management, though, it can be contained so you can get on with your life—and your dental care.
