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.

You may think an office cleaning is mainly cosmetic — giving your teeth that polished look and you that pleasant, “squeaky clean” feeling. But your dental hygienist is doing more than making your teeth look great during your cleaning session — they’re also providing a valuable service keeping your teeth and gums healthy.
Here, then, are 3 things your dental hygienist is doing during a cleaning session that protects your health.
Removing disease-causing plaque. An office cleaning produces more than a fresh and clean smile. Your hygienist is manually removing plaque and calculus (hardened plaque deposits) in hard to reach places or where it has built up despite your best efforts at brushing and flossing. This built-up plaque is a ready source of bacteria producing acids, which give rise to both tooth decay and gum disease. And for actual occurrences of the latter, plaque removal is an important part of the treatment to restore your gums to a healthy pink.
Checking for signs of dental disease. As your hygienist cleans your teeth, they’re also looking for abnormalities in the mouth’s soft tissue — lumps, bumps, sores, or swelling — that may indicate something more serious requiring further examination. They’re also assessing your overall gum health, probing any areas that might indicate gum disease. And, of course, they’re looking for cavities, softened enamel or other signs of tooth decay.
Helping you improve your oral hygiene.Â As proficient as they are, a dental hygienist can only do so much to help prevent dental disease; the rest — daily brushing and flossing — is on your shoulders. But you’re not completely on your own, because your hygienist is your best personal hygiene training partner: not only can they assess how well you’re doing in your daily regimen, but they can also give you expert advice and tips on improving your brushing and flossing performance.

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.
