Dental X-rays: The Inside Story

May 27th, 2020

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. Christopher Trentini 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 Greensboro, NC 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!

Digital X-rays

May 20th, 2020

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. Christopher Trentini 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 Greensboro, NC office. We’re happy to explain the science—and the benefits—behind this high-tech diagnostic tool.

Water Flossers and Braces

May 13th, 2020

You devote a lot of energy to your orthodontic treatment. Appointments, rubber bands, adjustments, cleaning (so much cleaning)—and why? Because you know that your attractive, healthy smile will be well worth the effort.

But if you find that keeping your teeth and braces clean requires more time and energy than it should, and you’re still not getting the results you’d like, a water flosser might be just the tool you need to help make your cleaning routine easier and more effective.

Plaque and tartar can be a real problem when you wear braces. Cleaning around braces and wires can be a challenge, and it can be difficult to get floss between your teeth and close to your gums, even with special threaders or floss designed to slip behind your wires.

But ignoring bacteria and plaque build-up can lead to cavities, weakened or discolored enamel, and gum problems. Fortunately, a water flosser can help wash away food particles, bacteria, and plaque even in tight, hard-to-reach spaces, while providing gentle cleaning along sensitive gums.

Water flossers use a pulsing stream of water to remove food particles and plaque between and around teeth. You can adjust the water pressure to apply just the right amount of cleaning power, and then direct the flow to your gum line, between your teeth, around your brackets, or anywhere else you need. Some models even offer tapered heads with brushes designed specifically for cleaning braces.

You might consider investing in a water flosser if you have:

  • Mobility issues. If you have joint or mobility issues, a water flosser will let you clean those hard-to-reach areas more easily.
  • Lingual braces. Because lingual braces are on the inside of the teeth, they can be more difficult to clean effectively with regular brushing and flossing.
  • Problems removing plaque. If you find that you are brushing and flossing regularly, but still have plaque build-up around your braces, give water flossing a try.

A beautiful smile is well worth all the time and effort you are devoting to it. If you think a water flosser might save you a bit of that time and effort, and provide better cleaning power, talk to Dr. Christopher Trentini  about your options during your next visit to our Greensboro, NC office. We’ll let you know if traditional flossing, a water flosser, or a combination of the two will give you your cleanest, healthiest smile.

Gums and Braces

May 6th, 2020

“Yes,” you’re thinking, “I shouldn’t be chewing sugary, sticky gum while I’m wearing my braces.” Or perhaps, “I should check with my orthodontist to see if this sugar-free gum is safe for my braces.” And these are both great thoughts—but today, we’re thinking about gums of a different sort!

While you’ve been taking care of your teeth with regular brushing and flossing, you’ve also been taking care of your gums. And now that you’re wearing braces, your gums need a bit of special attention to keep them their healthiest.

We tend to think of gum disease as an adult problem. In fact, periodontitis, or serious gum disease, is one of the most common chronic infections in the adult population. But young gums need care, too! Gingivitis, a milder form of gum disease, is unfortunately a common problem for both children and adults.

Gingivitis is an inflammation of the gums caused by the build-up of plaque and tartar. When plaque builds up, it irritates delicate gum tissue. And while gingivitis is not as serious as periodontitis, the symptoms caused by this disease are nothing to smile about:

  • Redness
  • Tenderness and soreness
  • Swelling
  • Bleeding
  • Bad Breath

If you’re already feeling a little tender or swollen after an adjustment, the added discomfort caused by gingivitis is the last thing you want. But even worse, neglected gingivitis can lead to more serious infections of gum and even bone tissue. Luckily, gingivitis is both preventable and treatable with proper dental care.

So, how to protect your gums? We have some suggestions.

  • Brushing Better with Braces

It can be hard to brush around your brackets and wires, but keeping these areas free of food particles and plaque makes for healthy gums—and fewer cavities! There are specially designed manual toothbrushes made for braces wearers, and tiny interproximal brushes that can reach tight spaces. Or, perhaps an electric toothbrush will do a better job for you. Just be sure to brush after each meal for the most complete removal of bacteria and plaque.

  • Learn New Flossing Techniques

You might wonder how on earth you’ll get in between your teeth with your wires and brackets in the way. We have the answers! We know the best techniques for flossing your specific braces, and we’ll recommend specially designed flossing tools to make the job easier. Water flossers can also be a great help for cleaning in tight spots. Be sure to make flossing part of your daily routine—you’ll be able to remove plaque from places brushing just can’t reach.

  • Rinsing? Recommended.

Talk to Dr. Christopher Trentini about the best dental rinses for reducing plaque and tartar, or how gargling can help prevent irritation. And drink water! Water helps wash away plaque and bacteria, and is a great way to rinse teeth and braces if you absolutely can’t brush after eating.

  • Keep up with Professional Cleanings

Be sure to keep up with your regular dental exams and cleanings. Your dentist or hygienist will be able to remove any plaque or tartar build up that home brushing can’t handle.

We want your time in braces to be as healthy—and comfortable—as possible. If you have any gum discomfort, swelling, or sensitivity, give our Greensboro, NC office a call. With prompt action, gingivitis can be treated, and with careful attention to your cleaning routine, gingivitis can be prevented altogether. Something to think about!
