Digital X-Rays

Digital radiographs, commonly known as x-rays, are a vital diagnostic and assessment tool for dentists. We offer modern digital x-rays at our practice, both for your convenience and for efficiency of treatment.

In the past, dental x-rays were captured using a film process similar to an analog photograph. With the advent of digital imaging, computerized radiography has become the dental industry standard. Digital x-rays require up to 90% less radiation than conventional film-type x-rays, which were already fairly low risk to begin with. Instead of using the traditional silver-oxide x-ray film, which must be developed and then fixed in caustic and environmentally damaging solutions, the new system takes pictures via a small electronic sensor.

What Is A Digital X-Ray?

X-rays, also known as radiographs, have long been part of preventive care in dentistry. X-rays are a form of electromagnetic radiation that is invisible to human eyes. When scientists first discovered evidence of these electromagnetic rays, they weren’t sure what they were, so they called them x-rays, and the name stuck.

X-rays can pass through the soft tissues of the face and mouth (lips, cheeks, etc.) but are absorbed by the hard material of teeth and bone. This allows the dentist to see potential oral health issues that may not be easily visible from the outside. X-rays are used primarily to find cavities, but dentists also use them to look at tooth roots, to evaluate the health of the bone surrounding the tooth, to assess possible periodontal (gum) disease problems, to analyze tooth and jaw positioning and to keep track of development in younger patients.

Type of Dental Digital X-Rays

While there are several types of dental x-rays (including periapical and full-mouth), the most common kind of dental x-rays are called bite-wing x-rays, based on the wing shape of the films that were once used. These x-rays are done while you’re in the dental chair and capture an image of several teeth at a time, roots included. A dental team member will place a sensor in a certain part of your mouth and ask you to bite down while they aim a tube-shaped device at your face. This is the x-ray emitter, which sends the x-rays through your tissues and onto the sensor in your mouth. No light or heat will come from the emitter. There is usually no discomfort associated with getting dental x-rays.

The Advantage of Modern Digital X-Rays

One other big advantage of modern digital x-rays over the old film type is the lack of a lag time between taking the x-rays and being able to examine them. The x-ray picture of the tooth can be instantaneously transmitted onto a monitor in the treatment room so we can see your teeth and surrounding structures while you’re still in the chair. The immediacy of digital x-rays allows the dentist to assess the health of your teeth and identify potential problems right away. The dentist can easily point out potential trouble spots to you, allowing you to see and understand your oral health condition as the dentist explains it. The digital files are also easy to share with any other dental professionals who might be involved in your care in the future.
