Modern orthodontic technology has changed the way you wear braces. Brackets are smaller and come in a variety of shapes and colors. Wires are more efficient. Clear aligners can eliminate the need for brackets and wires altogether. And your high-tech advantages don’t stop there—today’s digital X-rays make creating your treatment plan even more convenient and efficient.

Why Are X-rays Necessary?

Beautifully aligned teeth and a healthy bite are the visible result of your orthodontic work, but there’s a lot going on above and below the surface that needs to be discovered and taken into account before your treatment even begins. X-rays help Dr. Meehan evaluate:

• The size, shape, and position of your teeth, including impacted teeth and wisdom teeth
• The size, position, and health of your roots throughout treatment
• The size and shape of your jaw bones, and how they affect your teeth alignment and bite
• Your progress during different phases of treatment
• The most effective type of retainer for protecting your beautiful smile after treatment.

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 evaluating your teeth and the bone structure surrounding them.

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.

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

Modern technology means traditional X-rays expose patients to less radiation than ever before, but digital X-rays have significant advantages here as well. Radiation exposure can be reduced by an additional 10%, 20%, or more with a digital radiograph.

And while all types of dental X-rays expose you to very little radiation, it’s always best to reduce exposure whenever possible.

• More Convenient for Sharing and Transmitting

If you need to share your X-rays with another dentist 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 treatment possible. Digital X-rays are an important tool for orthodontists, helping us to provide you with the best treatment plan possible. If you have any questions about digital X-ray technology, contact our Palos Heights, IL office. We’re happy to explain the science—and the benefits—behind this high-tech diagnostic tool.

Plaque is a sticky subject! It sticks to the enamel of our teeth above and below the gum line, and it collects around braces. Plaque is one of the major causes of tooth decay and gum disease, and our teeth are under daily attack by this filmy menace.

What are the facts about plaque, and how can we fight back? Read on for some effective strategies!

What Is Plaque?

Plaque is a sticky film that builds up on our teeth, largely made up of millions of different types of oral bacteria. Plaque is a colorless biofilm at first, but as it collects, it takes on a white or yellow tint. If you haven’t brushed for a few days, that fuzziness you feel on your teeth is plaque build-up. Unless it’s removed, plaque hardens within a matter of days to become tartar.

• Tip: You can remove plaque with careful brushing and flossing, but it takes a dental professional to remove tartar. Be proactive!

Why Does Plaque Cause Cavities?

Bacteria in plaque use our food as their food, especially sugars and carbs. They can then transform these nutrients into acids, which attack our tooth enamel, weakening it and leaving it vulnerable to further erosion and eventual decay.

• Tip: Cavities aren’t the only damage caused by accumulated plaque. Plaque also collects along and below the gum line. If tartar forms here, it irritates delicate gum tissue, leading to gingivitis and more serious gum disease. Make sure you don’t forget your gums when you brush and floss.

When Does Plaque Build Up?

The short answer? Plaque is always forming, because oral bacteria are a natural part of our biology. (In fact, there are even oral bacterial which are beneficial.) Plaque starts building up within minutes after eating, and during the night as we sleep.

That’s why we recommend brushing for two minutes at least twice a day, and flossing at least once a day. When you wear braces or aligners, brushing more often is a good idea. Food collecting around braces or inside aligners is a feast for plaque! Ask Dr. Meehan for suggestions for your best brushing schedule.

• Tip: Just because plaque is unavoidable, that doesn’t mean we need to give the bacteria in plaque any additional encouragement. Every time you have a meal or a snack that’s heavy in carbs and sugars, you are providing more fuel for acid production. Cutting down on foods like sugary desserts and sodas is not only nutrition-healthy, it’s tooth-healthy!

Where Does Plaque Collect?

Plaque builds up all over tooth surfaces, at the gum line, and even below the gum line. It’s especially easy to miss in hard-to-reach places like the irregular surfaces of molars, between the teeth, behind our front teeth, and near the gum line. Plaque also collects around your braces, and requires special care to make sure your teeth don’t suffer cavities or the white spots caused by demineralization.

• Tip: One of the ways plaque avoids detection is its invisibility. Fortunately, if you’re having trouble brushing away all your plaque, there are plaque-disclosing toothpastes and chewable tablets available in the dental aisle which reveal the plaque hiding between, behind, or around your teeth by tinting it with a can’t-miss color. Just brush the color away, and you’ve brushed the plaque away as well.

How Do We Clean Away Plaque?

Use the Right Tools

Floss at least once a day. There are different materials, sizes, and coatings for floss, so you can find one that’s comfortable for you. Floss reaches those spots in between teeth and around the gum line that brushes miss.

Choose a soft toothbrush (soft bristles are better for your enamel) and change it every three to four months, or as soon as the bristles show wear. Make sure the head is the right size—too big, and it’s not only uncomfortable, but you won’t be able to reach all the surfaces you need to.

• Tips: There are special dental flosses created just for your braces. You can also use interproximal brushes water flosser to clean around wires and brackets. If you have trouble removing plaque around your teeth and braces with a manual toothbrush, consider an electric model. Several studies have shown a reduction in plaque with the use of an electric brush.

Use the Right Toothpaste

There are many toothpastes specifically formulated to fight plaque and tartar. And fluoride toothpastes not only fight cavities, they can strengthen your enamel.

• Tip: Studies have shown that toothpastes with baking soda, in particular, are effective in reducing plaque. Ask Dr. Meehan for a recommendation the next time you’re at our Palos Heights, IL office.

Use the Right Technique

What not to do?  A forceful, horizontal sawing motion is awkward, hard on your enamel, and misses plaque and debris between the teeth. Technique is important—not for style points, but for cleaner teeth!

Hold your toothbrush at a 45-degree angle, especially at the gum line, to gently remove plaque from teeth and gums. Use short strokes or a circular motion to clean as much of the surface and between the teeth as possible. Brush the inside of your front teeth with careful vertical strokes—remember, that’s one place where plaque is easy to overlook. The same holds true for the tops of your molars, so thoroughly clean those uneven surfaces.

If you wear braces, be sure to clean thoroughly around brackets and wires, where plaque can accumulate quickly.

• Tip: If you wear clear aligners, don’t forget to give them a gentle brushing as well! Plaque can stick to aligners, causing discoloration and odors, so follow our cleaning instructions carefully.

Who Can Help You Fight Plaque?

Even when you do your best at home, plaque can still be a sticky problem. That’s why we advise regular professional cleanings, which not only remove any plaque that’s hiding away, but also eliminate any built-up tartar around your braces. And, of course, there you can learn all about how to keep your teeth their cleanest.

True, you’re fighting plaque every day, but you have all the tools you need to make sure your teeth and gums stay healthy. You’re winning the battle with plaque every time you eat a nutritious meal, and every time you brush and floss. With that kind of strategy, plaque doesn’t stand a chance. And your bright smile and healthy teeth and gums? That’s a victory worth celebrating!

We’re all friends here, so if you sometimes feel a bit nervous before your orthodontic appointments, no judging! Ask us about any worries you might have. We are happy to explain procedures, equipment, and your orthodontic options so you know exactly what is going on during treatment. And if X-rays are a concern, we can put your mind at ease here as well.

What Exactly Are X-rays?

Sometimes patients feel reluctant about the process of imaging because X-rays are a kind of radiation. But the fact is, radiation is all around us. We are exposed to radiation naturally from our soil and water, sun and air, as well as from modern inventions such as cell phones, Wi-Fi, and air travel.

Why is radiation so common? Because matter throughout the universe constantly gives off energy, and the energy that is emitted is called radiation. This radiation takes two forms—as particles (which we don’t need to consider!) and as traveling rays. This second type is known as electromagnetic radiation, created by photons traveling in regular waves at the speed of light.

We are exposed to electromagnetic radiation every day, because, whether we can see them or not, these different wavelengths and frequencies create various forms of light. Radio waves, microwaves, infrared, visible, and ultraviolet light, X-rays, and gamma rays are all part of the electromagnetic light spectrum.

Different types of radiation on this spectrum have different wavelengths and different frequencies, and produce different amounts of energy. Longer wavelengths mean lower frequencies and less energy. Because X-rays have shorter wavelengths and higher frequencies than, for example, radio waves and visible light, they have more energy.

How Do Dental X-rays Work?

An X-ray machine produces a very narrow beam of X-ray photons. This beam passes through the body and captures images of our teeth and jaws on special film or digital sensors inside the mouth (intraoral X-rays), or on film or sensors located outside the mouth (extraoral X-rays). These X-ray images are also known as radiographs.

Why are X-rays able to take pictures inside our bodies? Remember that higher energy we talked about earlier? This energy enables X-rays to pass through the softer, less dense parts of our bodies, which are seen as gray background in a radiograph. But some substances in our bodies absorb X-rays, such as the calcium found in our bones and teeth. This is why they show up as sharp white images in radiographs. 

There are many different types of dental X-rays used in orthodontics, including:

• Occlusal X-rays, which show the entire arch of teeth in the upper or lower jaw.
• Panoramic X-rays, which use a special machine to rotate around the head to create a complete two-dimensional picture of teeth and jaws.
• Cephalometric X-rays, which show the patient’s entire profile, and the position and development of the teeth and jaws.
• Cone Beam Computed Tomography, an external device which uses digital images to create a three-dimensional picture of the teeth and jaws.

Why Do We Need X-rays?

You might have noticed that these X-rays, unlike, for example, typical bitewing X-rays, don’t take images of individual teeth. That is because orthodontists deal with the teeth in relationship to each other and to the structures around them.

Beautifully aligned teeth and a healthy bite are the visible result of your orthodontic work, but there’s a lot going on above and below the surface that needs to be discovered and taken into account before your treatment even begins. X-rays help us evaluate:

• The size, shape, and position of your teeth, including impacted teeth and wisdom teeth
• The size, position, and health of your roots throughout treatment
• The size and shape of your jaw bones, and how they affect your teeth alignment and bite
• Your progress during different phases of treatment

How Do Orthodontists Make Sure Your X-rays Are As Safe As They Can Be?

First of all, the amount of radiation you are exposed to with a dental X-ray is very small. In fact, a typical panoramic X-ray provides roughly the same amount of radiation we are exposed to through our natural surroundings in just one day. Even so, Dr. Meehan and our team are committed to making sure patients are exposed to as little radiation as possible.

Radiologists, the physicians who specialize in imaging procedures and diagnoses, recommend that all dentists and doctors follow the safety principal known as ALARA: “As Low As Reasonably Achievable.” This means using the lowest X-ray exposure necessary to achieve precise diagnostic results for all dental and medical patients.

The guidelines recommended for X-rays and other imaging have been designed to make sure all patients have the safest experience possible whenever they visit the dentist or the doctor. We ensure that imaging is safe and effective in a number of ways:

• We take X-rays only when they are necessary.
• We provide protective gear, such as apron shields and thyroid collars, whenever needed.
• We make use of modern X-ray equipment, for both traditional X-rays and digital X-rays, which exposes patients to a lower amount of radiation than ever before.
• When treating children, we set exposure times based on each child’s size and age.

And now that we’ve talked about some things you might like to know,

Please Let Us Know If . . .

• You are changing orthodontists and have had previous orthodontic X-rays taken. Ask to have your older X-rays sent to our office so we have a complete record of your orthodontic history. (With digital X-ray technology, this transfer can be accomplished with e-mail!)
• You’re pregnant, or think you might be pregnant. Even though radiation exposure is very low with dental radiographs, unless there is a dental emergency, dentists and doctors recommend against X-rays for pregnant patients.

X-rays play an important part in helping us make sure your orthodontic treatment provides you with a lifetime of beautiful and healthy smiles. If you have any concerns, contact our Palos Heights, IL office. When it comes to making sure you’re comfortable with all of our procedures, including any X-rays that might be necessary, we’re happy to give you all the inside information!

Press Pause

If you are getting braces in the near future, it’s very important to see your regular dentist first. That way, any cavities or other dental problems can be treated before your first orthodontic appointment at our Palos Heights, IL office.

Play it Safe

Once you have your braces, you’ll hearing a lot about how you need to be especially careful with your dental hygiene. Why? Because wires and brackets are obstacles to getting your teeth and gum area their cleanest. Plaque and food particles tend to stick to braces, and all too often can be missed while brushing. Plaque builds up around your gum line and brackets, and, in a very short time, can lead to sensitivity, demineralization, and cavities.

What can you do to prevent tooth decay?

• Increase Your Brushing Time

Instead of brushing twice a day, start brushing for two minutes after every meal. Put together a travel bag with a small toothbrush, toothpaste, floss, and interproximal brushes to clean your teeth when you’re on the go. If you absolutely can’t brush, rinse carefully with water, and then brush as soon as you can.

• Flossing—More Important than Ever

Use the flossing tools designed just for braces to make sure you’ve removed food particles and plaque from around your braces and gums. A water flosser can be helpful if manual flossing isn’t effective.

• Keep Up with Your Regular Dental Care

Schedule regular checkups and professional cleanings at your dentist’s office. They will be able to remove plaque you might miss at home.  

• Follow Our Advice

We’ll give you instructions on how to brush and floss, what products to use, and diet suggestions (such as keeping sugary and sticky foods off the menu and away from your braces). If we notice plaque building up around your gums and brackets, we’ll let you know that you need to step up your hygiene habits. We can also suggest rinses and toothpastes that help fight plaque.

But if, despite all your efforts, you do get a cavity? There are options!

• Ignoring Your Cavity?

Not an option. You shouldn’t wait until you are out of braces to get a cavity treated. This just gives decay a chance to spread further.

• Working With Your Braces

Repairing a cavity means removing the decay in the tooth, cleaning the area, and then filling the tooth. If your cavity isn’t located near your bands, brackets, or wires, your dentist might be able to work around your braces, and you can get your cavity treated during a regular dental appointment.

• Removing Parts of Your Braces for Treatment

Sometimes a cavity is located in a spot that your dentist can’t reach because of your braces. In that case, we’re able to coordinate with your dentist and remove a wire or bracket temporarily so you can have your tooth filled. Make an appointment to replace your bracket and re-attach your wire, and you’ll be back on schedule as soon as possible.

Fast Forward
