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. McGue 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 Chesterton office. We’re happy to explain the science—and the benefits—of high-tech radiography.

Should a quick bite between meals make us feel guilty? Or worse, make our teeth suffer a greater risk of cavities? Let’s avoid both those possibilities! We have several tooth-healthy snacking strategies designed to help you keep your enamel cavity-free while preventing snacker’s remorse.

But first, a word or two about why we may find snacking unappetizing.

• Please, Don’t Feed the Bacteria!

The bacteria in plaque feed on sugars and leave acidic waste products behind. These acids attack enamel, dissolving the calcium and phosphorus minerals that keep it strong. Weakened enamel leaves teeth vulnerable to decay. That’s why Dr. McGue and our Chesterton team recommend avoiding a steady diet of sugary treats.

Even if you’re not reaching for a soda, or grabbing a candy bar, many snack foods are filled with added sugars. Check the nutritional labels before you indulge to avoid sugar surprises.

• Off Balance?

Bacteria plus sugar equals more acidic conditions in the mouth. This change in the oral pH balance also reduces our natural defenses against cavity-causing acids.

A well-balanced oral environment depends on saliva to keep acids in check. Saliva washes away lingering food particles after meals, and it neutralizes acidic conditions in the mouth over the course of the day.

How does snacking interfere? Immediately after eating or drinking, acids in saliva increase. It takes about 20 minutes for saliva’s neutralizing process to begin. When we snack throughout the day, saliva doesn’t have a chance to reduce acids as long or as effectively.

• Staying Power

Sticky and chewy snacks tend to stick to the tops of molars and between the teeth. This gives bacteria more fuel and more time to attack tooth enamel. It’s not just candies that are the culprits here. Chips, bread, pizza crusts, pastries—these simple carbs stick to teeth and break down easily into sugars.

But we promised some *positive* strategic snacking ideas. Here are some ways to make sure that snacking doesn’t put you at a much greater risk for cavities.

• Be Choosy

Avoid processed treats that are high in added sugars. If you’re craving something sweet, fresh fruits provide sweetness with vitamins included.

Crispy fruits such as apples and Bosc pears, as well as vegetables like celery and carrots, provide gentle scrubbing action to help clean teeth between brushings.

Snacking on cheese helps neutralize acids, and other dairy products are high in calcium and phosphorus, helping rebuild the minerals that acids leach out of enamel.

Eat whole grain breads, pastas, and pastries. They offer more nutrients, and don’t break down into sugars as easily.

Finally, when it’s time to indulge in a sugar-rich treat, save it for a meal. There’s a better chance that other foods will balance the acids created by sugar, and you’ll be getting the most out of saliva’s neutralizing abilities. Speaking of which,

• Stay Neutral

When you’re craving something flavorful without giving bacteria more fuel for acid production, consider sugar-free gum. Sugar-free gum saves you from adding sugar to your diet, and it increases saliva production as you chew. If we give you the all-clear, chewing a piece or two of gum during the day can help curb your sugar cravings and protect your enamel.

Thirsty? Drink water instead of sodas or energy drinks with your snacks. Water washes away food particles, cuts down on acidity, and provides fluoride to strengthen and protect teeth.

• To Brush or Not to Brush?

It’s always a good idea to brush after eating. But since eating sugary or acidic foods can leave enamel vulnerable to toothbrush abrasion, many dentists recommend waiting 30 minutes after you snack before brushing. Ask Dr. McGue what’s best for your teeth.

If you can’t brush, rinse with water after eating or drinking.

If you wear braces or aligners, be sure to check with Dr. McGue about snacking, gum, best times to brush, and any other diet questions.

Talk to Dr. McGue about your snacking habits. Learning when and how to snack is as important as deciding what to snack on. Finding the perfect balance means you can enjoy a mid-day energy boost without guilt—and without risking tooth decay!

The Good News

Carbohydrates are one of the body’s essential macronutrients (along with protein and fat). We use carbs to convert the food we eat into energy. How does this work? It’s a sophisticated process:

• Carbs break down into sugars as we digest them
• Sugars are absorbed into our bloodstream
• The pancreas releases insulin when blood sugar levels rise
• Insulin enables sugars to move from our blood to our cells
• Cells throughout the body use this sugar for energy.

Without the necessary amount of carbohydrates, our bodies lose a vital source of energy. So, why are carbs a dental concern?

The Bad News

Some foods immediately begin breaking down into sugars in the mouth. Sugars are a favorite food source for the oral bacteria that form plaque. They use this sugar to produce the acids that weaken our enamel and lead to cavities. And the more often we eat these foods, and the longer they remain in the mouth, the more damage our enamel suffers.

But there’s a silver lining! We can be healthier physically and get a jump on preventing damage from sugary treats by becoming more discriminating in our choice of carbs and timing our indulgences wisely.

Good Carb/Bad Carb

Unprocessed, complex carbohydrates are found in foods like whole-grain breads and cereals, legumes, and vegetables. They contain the vitamins, minerals, and fibers which are lost when foods are refined. They are composed of larger, more complex molecules, and so they break down gradually for sustained energy.

Some simple carbohydrates break down into sugars more quickly, but also offer important vitamins, minerals, and fiber. Fruits and dairy products, for example, are an important part of a balanced diet.

But some carbs are not pulling their nutritional weight. Refined sugars (think candies, desserts, and sodas) and refined starches (white bread and rice, potato chips, pastries) break down quickly into sugar in the mouth. Worse, many of these foods tend to stick around. Sticky sugars and sticky starches cling to our enamel and hide between the teeth and in the crevices of our molars. Not only do these treats provide a sugary feast for acid-producing bacteria, they take their time doing it!

So, What to Do?

If you have a diet filled with healthy carbs (whole grains, fruit and vegetables, legumes, dairy products), you’re already on the right track. Kudos! But does this mean no desserts? Ever?

No! We all need a cookie sometimes. But you can decrease the chance of enamel damage by interrupting the carbs to cavities cycle.

First, if you are indulging in a rich dessert or some salty chips, better to do it as part of a meal. When you eat a full meal, your body produces more saliva. Saliva not only helps wash away food particles, it also helps neutralize the acids that damage enamel.

Secondly, if you eat simple carbs and sugars all day, your mouth and teeth are being treated to acids all day. If you are going for a snack, there are many great options that don’t use refined sugars and starches. Think fruit smoothies (with a big dollop of vegetables) or whole-grain crackers with hard cheese instead of a can of soda and a bag of pretzels.

Carbs aren’t really bad, they’re just misunderstood. Talk to Dr. McGue at your next checkup at our Chesterton office for ideas for the best carbohydrate choices for healthy metabolisms and healthy smiles!
