X-rays are a vital diagnostic tool for any dental professional. X-rays help your endodontist perform a root canal, your orthodontist check the position of a tooth’s root, your oral surgeon discover a fracture. X-rays reveal what we can’t see with the naked eye—and that’s why they are an especially important tool for Dr. Chad Vanourny as well.

Why Are X-rays Necessary?

There’s a lot going on below the surface. An X-ray can reveal such conditions as cavities between teeth or underneath fillings, abscesses and other infections in the bone, impacted wisdom teeth, and cysts and tumors. They can also show the size, shape, and density of the bone beneath the teeth, which is essential information for dental implant procedures or dentures.

How Do X-rays Work?

Traditional X-rays, or radiographs, make use of film just like traditional cameras. When you have an intraoral X-ray, for example, the film is sealed in a moisture- and light-proof packet, and placed inside the mouth to capture images of specific teeth and the bone around them.

The X-ray machine is aligned precisely with the film and an exposure is taken. The image at this point is latent, and won’t show on the film, because, just like photo film, traditional radiographs need to be chemically processed before they produce a visible image.

Digital technology, on the other hand, uses an electronic sensor instead of film. For an intraoral digital X-ray, a small sensor is positioned in the mouth just like a film. When the X-ray is taken, a digital image capture device produces an image which is formed by a matrix of pixels instead of a photo-like film exposure. This format allows the image to be sent directly to a computer for immediate display without requiring processing.

Even though these methods seem very similar, digital X-rays offer some significant advantages over traditional films. Let’s look at how they compare, more or less.

• More Diagnostic Advantages

A traditional X-ray is a fixed image. It cannot be modified or enhanced. Here the digital X-ray offers a clear advantage in diagnosis.

Just as you can enlarge certain types of images on your computer without blurring or losing detail, a digital X-ray uses computer software to magnify images while keeping their details sharp. They can also be enhanced through brightness and contrast applications to make details stand out even more. Both of these benefits are extremely helpful for diagnosis, especially when looking for small cavities, problems in the roots and surrounding bone, or developing wisdom teeth.

There is even digital subtraction radiography software available that can be used to compare recent images to older ones, removing (“subtracting”) all the similarities in the two images to display only the changes in the two—even small changes—that have taken place over time.

• Less Exposure to Radiation

Dental X-rays expose patients to very low levels of radiation, and modern technology means traditional X-rays expose patients to less radiation than ever before. Even so, digital X-rays have significant advantages. Radiation exposure can be reduced by an additional 10%, 20%, or more with a digital radiograph.

• More Convenient for Sharing and Transmitting

If you need to share your X-rays with another dental specialist or physician, digital technology allows you to simply have them e-mailed to another office or multiple offices. You no longer need to worry about preserving physical copies, either.

• Less Waste

Unlike traditional X-rays, digital X-rays don’t need to be processed, so you save time in the office. And while the processing time is not significant (usually several minutes), if you need to repeat some X-rays for a clearer picture, or require different images for several teeth, this time can add up.

Digital X-rays are also more eco-friendly.  The fact that they don’t need to be developed means that the chemicals used to process traditional films are no longer necessary—which also means that there is no need to dispose of chemical waste products afterward.

Our goal is to provide you with the safest, most efficient, and most effective dental treatment possible, and digital X-rays help us do that. If you have any questions about digital X-ray technology, contact our Charlotte office. We’re happy to explain the science—and the benefits—of high-tech radiography.

Many varieties of fillings are available at our Charlotte office. Most people are familiar with traditional amalgam fillings: those big silver spots on top of teeth.

Made from a mixture of silver, tin, zinc, copper, and mercury, amalgam fillings have been used to fill cavities for more than 100 years. They offer several advantages, including:

• High durability for large cavities or cavities on molars
• Quick hardening time for areas that are difficult to keep dry during placement
• Reduced placement time for children and special-needs patients who may have a difficult time keeping still during treatment

Although dental amalgam is a safe and commonly used dental material, you might wonder about its mercury content. You should know that when it’s combined with the other metals, mercury forms a safe, stable material.

The American Dental Association, U.S. Centers for Disease Control and Prevention, U. S. Food and Drug Administration, and World Health Organization all agree that based on extensive scientific evidence, dental amalgam is a safe and effective cavity-filling material.

White Fillings

Newer, mercury-free, resin-based composite fillings (white fillings) are also available at our Charlotte office. Composite resin fillings are made from plastic mixed with powdered glass to make them stronger.

Resin-based fillings offer several benefits for patients, including:

• They match the color of teeth
• Less tooth structure needs to be removed than with amalgam fillings
• BPA-free materials can be used

Resin-based composite fillings also have some disadvantages, including:

• Higher cost than amalgam fillings
• Inlays may take more than one visit
• Requires more time to place than amalgam fillings

There’s a lot to think about when you have to get a cavity filled. We recommend you do your homework and speak with Dr. Chad Vanourny before deciding what’s best for you or your family.

Before electric toothbrushes, before dental floss, before fluoride rinses, in fact, before recorded history, people who cared about their dental health had one primary tool—the toothpick. Ancient bronze toothpicks, bejeweled Renaissance picks, and the more humble modern wooden picks have been instrumental in promoting dental hygiene for centuries.

And, while that clean, simple design is still a good one, modern technology has found a way to build an even better toothpick. Today’s interdental picks not only dislodge food particles effectively, but now gum stimulation, cleaner orthodontic appliances, and fresher breath are available literally at our fingertips. Most important, these picks are just as effective as floss for removing plaque.

• Wood? Still Good!

Today’s softer wooden picks come in several shapes designed to fit comfortably and snugly between the teeth. Using a gentle in-and-out motion, you can clean between your teeth as you remove plaque from the tooth surface. But that’s not the only benefit! As you move the wide end of the pick up and down between teeth and gums, you are actually stimulating your gum tissue as well.  They even come with mint flavoring to refresh your mouth as you clean. And, of course, wood and bamboo picks are biodegradable.

• Plastic? Fantastic!

If you’d like something a little more yielding than wooden dental picks, you have options. Soft dental picks are available that use rubber “bristles” on a plastic stem to gently ease their way between teeth. The heads are available in different diameters to accommodate tight or wide spacing between the teeth. Straight or curved stems provide the accessibility you need. If you have latex allergies, be sure to choose a rubber product that is latex-free.

• Interproximal Brushes? Here’s What the Buzz Is

You might have missed these miniature brushes in the dental care aisle, but they are worth looking for. Interproximal brushes have small cone-shaped heads with nylon bristles for cleaning food particles and plaque from between the teeth. They are good for more than one use, and some are available with angled or bendable handles for hard-to-reach spots. They come in different diameters, from wide to extremely fine, to suit the spacing of your teeth. Interdental brushes are especially useful for braces wearers, who can use these clever tools to clean tight, tricky areas under wires and around brackets.

Even though bronze, bejeweled, or golden toothpicks aren’t available in the dental aisle of the local drugstore, increased efficiency and function are well worth the trade-off. If for any reason you have trouble flossing, or if you like the idea of massaging your gums as you clean your teeth, or if you wear braces, or if you want a burst of mint flavor—for any number of reasons today’s dental picks are worth a try. Talk to Dr. Chad Vanourny at your next visit to our Charlotte office, and we’ll be happy to give you some recommendations. 

Anyone who has had a compromised tooth knows that the amount of discomfort it causes can be extremely unpleasant. Although no one looks forward to a root canal, this procedure is actually the best way to both eliminate pain and save your tooth. If the pulp inside your tooth is infected or damaged, a root canal is probably necessary.  

The process is relatively straightforward and can take place over one or two visits to our Charlotte office. The area around the tooth is numbed, the pulp is removed from the inside of the tooth, the area is thoroughly cleaned, and a temporary filling or crown is placed on the tooth to prevent bacteria and food from entering the site. A permanent crown will be fabricated and affixed to the tooth at a later visit.

Once your root canal is finished, recovery is usually only a matter of days. What can you to keep yourself as comfortable as possible during that time?

• The area around the affected tooth might be somewhat sore or sensitive for a few days. Let us know, and we can talk about medication to reduce pain and inflammation. If you are prescribed antibiotics, be sure to take the entire course of medication as directed.
• Taking an ibuprofen (if this is a pain reliever that is safe for you) before the anesthetic wears off will reduce the soreness in the hours immediately after the procedure.
• Wait until the numbness is gone before eating to avoid biting down on a temporary filling (or your tongue). Hot drinks are also best avoided.
• Avoid chewing on the side of the affected tooth until the restoration is complete. A soft diet is recommended for the first several days—chewy, sticky, and crunchy foods should wait.
• Continue with regular brushing and flossing.
• Call Dr. Chad Vanourny immediately if you experience severe pain or visible swelling, if you have an allergic response to medication, if your bite feels uneven, or if you lose the temporary filling.

Follow the instructions we’ll give you carefully, and feel free to call us with any concerns. We want to ensure that your root canal is as pain-free and worry-free as possible.
