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. Allen 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 San Diego office. We’re happy to explain the science—and the benefits—behind this high-tech diagnostic tool.

X-rays have been a function of dental healthcare for a long time. That in and of itself should be good news, because it means we've had plenty of time to improve them. While there is always some risk in exposure to radiation, dental X-ray exposure has decreased significantly due to all the advances in technology. So there’s risk, but X-rays are quite safe.

Think of X-rays as you would about a car. Automobiles these days have all kinds of technology to make them as safe as possible. There's still a chance that you’ll suffer an accident. Would you stop using a car because of that risk? When it comes to dental X-rays, Dr. Allen and our team believe the positives clearly outweigh the negatives.

X-rays can be done digitally or with film. For film, X-rays require different exposures at different speeds to produce the image. Digital X-rays have software that automatically adjusts the exposure and produces the X-ray in a digital file. Since they substantially reduce your exposure to radiation, digital X-rays are the current standard in dental offices.

In addition to digital X-rays, lead aprons are an essential piece of X-ray safety. They help protect internal organs from X-rays by acting as a shield. They usually come with a thyroid collar as well, since that is one of the most vulnerable areas to X-rays in the body. Lead aprons can absorb up to 95% of any scatter rays that result from an X-ray. Not bad, right?

Although dental X-rays involve some radiation exposure (not all of it can be eliminated), so does everyday life. Getting too much sun, for example, can be dangerous. The truth is, we accumulate radiation in our bodies over a lifetime, so it’s worthwhile to be aware and avoid as much unnecessary exposure as possible. When it comes to your dental health, though, getting an X-ray — especially when your doctor says you need it — offers more benefits than risks.

Now that you have braces, it is more important than ever to maintain good oral hygiene during your treatment, as Dr. Allen will tell you. While we trust you will continue brushing and flossing on a regular basis throughout your treatment at Davis Orthodontics, you also have to mindful of what you eat. While all those sweet, sour, and sticky candies may taste great, these treats can actually damage your teeth and braces!

Sour candies  can be acidic to your teeth, and actually wear down the enamel that protects them, resulting in tooth decay and cavities. If you do indulge in eating these candies at some point during your treatment, be sure to wash your mouth out with water, drink milk or eat a few slices of cheese. These foods will help neutralize the acid in your mouth.

Besides cavities and tooth decay, many people do not realize that good oral health and hygiene are important to your overall health, too; researchers have discovered the connection between periodontal disease and other major health concerns, such as heart disease. Therefore, it is important to maintain a good oral hygiene routine just as you did before your braces. This includes visiting your dentist here in San Diego every six months, brushing and flossing daily, and using an antibacterial mouthwash, as well as visiting Dr. Allen for your regular adjustment appointments.

For more questions about foods you should avoid while wearing braces, or if you have any general questions about your treatment, we encourage you to give us a call, ask us at your next adjustment appointment or ask us on Facebook!
