TestYoureBrushingandFlossingSuccesswithaPlaqueDisclosingAgent

Brushing and flossing your teeth provides a lot of benefits, including a brighter smile and fresher breath. But the primary benefit—and ultimate goal—is removing dental plaque. This biofilm of bacteria and food remnants on tooth and gum surfaces is the number one cause for dental disease.

Brushing and flossing can effectively keep plaque under control. Unfortunately, plaque can be a stubborn foe, hiding in areas easily missed if you're not thorough enough.

So how do you know you're doing a good job brushing and flossing? One quick way is to use your tongue or dental floss to feel for any grittiness, a possible sign of remaining plaque. Ultimately, your dentist or hygienist can give you the best evaluation of your hygiene efforts during your three or six-month checkup.

But there's another way to find out more definitively how well you're removing plaque in between dental visits: a plaque disclosing agent. These over-the-counter products contain a dye solution that stains plaque so it stands out from clean tooth surfaces.

A disclosing agent, which can come in the form of tablets, swabs or a liquid, is easy to use. After brushing and flossing, you apply the agent according to the product's directions. The dye reacts with plaque to stain it a distinct color. You may also find products with two-tone dyes that stain older and newer plaque different colors to better gauge your overall effectiveness.

You then examine your teeth in the bathroom mirror, looking especially for patterns of missed plaque. For example, if you see dyed plaque running along the gum line, you'll know you need to concentrate your hygiene there.

After observing what you can do to improve your future efforts, you can then brush and floss your teeth to remove as much of the dyed plaque as you can. The staining from the dye is temporary and any remaining will fade over a few hours.

Using a disclosing agent regularly could help you improve your overall hygiene technique and reduce your risk of disease. Ask your dentist for recommendations on products.

WemayNeedtoBuilduptheBoneinYourJawbeforeImplants

Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.

For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.

Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by  at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.

That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.

If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.

With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.

Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

CrownscannowbemadeIn-OfficewiththeCADCAMSystem

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.
