You already know that taking care of your teeth can help prevent tooth decay and the need for extensive work such as root canals or implants, which can be inconvenient and expensive. But the benefits of good teeth can go far beyond having an attractive smile and being able to crunch carrots and chew meat.

The American Dental Association explains that healthy teeth are linked to a lower risk for heart disease and diabetes. Furthermore, recent research published in the British Journal of Sports Medicine states that good teeth can improve athletic performance among elite athletes.

Researchers examined the oral health of nearly 300 athletes in 25 sports at the 2012 Olympics in London. They looked for conditions such as dental caries, gingivitis, dental erosion, and periodontal disease, and asked about recent visits to a dentist.

Study investigators also asked athletes whether their oral health interfered with quality of life or athletic training and performance. The study concluded that poor oral health and fewer dental visits led to interference with preparation for competition.

This can happen for a few reasons. Tooth pain can disrupt sleep, which leads to slower reaction times. Oral health conditions can indicate chronic inflammation in the body, which means suboptimal performances on an elite level. Tooth pain can interfere with focus during training and competition.

Unfortunately, merely taking good care of your teeth won’t turn you into an Olympic gold medalist. However, the benefits can still be worthwhile. Even if healthy teeth provide little if any detectable gain in your athletic abilities, the potential benefits of maintaining a healthy mouth clearly go far beyond an attractive smile.

Practicing good oral hygiene and seeing Dr. Chad Vanourny regularly can promote your physical health, and maybe – just maybe – you will start to achieve an advantage over your weekend athletic opponents.

It's a moment many of our patients have experienced. One second you're chewing on a piece of gum, then suddenly you forget to keep chewing and swallow the entire rubbery gob whole! It's at this point you remember your mother warning you as a child that if you swallow gum it will stake a claim and take up residency in your belly for seven years. Dr. Chad Vanourny and our team at Catawba Valley Dental Care hate to take all the fun out of the mystery, but the truth is that chewing gum, when swallowed, will enter your stomach and move through your digestive system just like any other piece of food. So, if you ever accidentally swallow a piece of gum, there is no need to worry!

That being said, it's important to know that gum does not have any dietary benefits, so while it’s not exactly harmful to swallow, you still want to avoid swallowing it. If you are an avid gum-chewer, we encourage you to chew sugarless gum, especially if you are wearing braces, because gum with sugar can lead to cavities. Sugarless gum still has the same amount of flavor, but has fewer cavity-causing ingredients. In fact, many brands contain an additive called xylitol, a natural sweetener known to fight cavity-causing bacteria. Xylitol is also known to increase salivary flow as it rinses away plaque and acid.

The fact is, when the bacterium in your mouth breaks down sugar, what’s left behind is acid. This acid eats away at the enamel coating of your teeth, causing holes that we call cavities. Cavities can lead to other long-term mouth problems if they are not treated in time, so it is best to try and avoid overexposing your teeth to too many harmful substances!

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.
