X-rays are wildly important – helping your dentist identify and detect problems that can’t be found with a basic oral exam. You’ll take x-rays if you’re joining us as a new patient, and when your dentist deems it necessary to take new ones.

Digital x-rays have taken the place of traditional film x-rays, and provide a wide variety of benefits to both dentists and patients!

What Is a Digital X-Ray?

Instead of the usual paper tabs that fit awkwardly and can cause discomfort, a small sensor is put inside your mouth during a digital x-ray. A small, discreet line connects the sensor to a computer, which records a highly detailed image of your mouth. The image is then sent to a computer and quickly shown onto a screen for the dentist to examine.
Intraoral (from inside the mouth) and extraoral (from outside the mouth) x-rays are the two most common types of dental x-rays. The most common intraoral radiograph is a bitewing x-ray. Previously, uncomfortable bits of the film were inserted inside the patient’s mouth for them to bite down on while the x-ray was taken. The compact sensors of digital technology make this form of imaging much more comfortable. An extraoral x-ray in which a machine rotates around the head is known as a panoramic x-ray. The dentist can see the entire mouth with the images that result.

What Are the Benefits of Digital X-Rays?

In many respects, digital x-rays assist both the patient and the dentist. The following are some of the advantages:

  • Reduced chair time and wait time — results are instantaneous and highly accurate
  • Improved imaging — images can be enhanced, expanded, and optimized in a variety of ways
  • Less radiation —digital imaging exposes patients to 80% less radiation than traditional x-rays
  • Decreased environmental impact — digital x-rays reduce the amount of material and chemical waste generated by traditional film-based x-rays.


How often do I need to have a dental x-ray taken?
The frequency with which you will need to have dental x-rays depends on your overall oral health. If you are suffering from dental decay or disease, you may need to be x-rayed every six months. If you are in good oral health, you may only need a dental x-ray every couple of years.
Are x-rays dangerous?
Though dental x-rays do require very low doses of radiation exposure, they are considered very safe. The use of digital technology further reduces the level of radiation you receive from a dental x-rays.
Is it safe to have dental x-rays taken while pregnant?
Dental x-rays are very safe. However, if you are pregnant, it’s best to minimize dental treatments and avoid dental x-rays if possible. In the case of a dental emergency, your dental provider will take all precautions available to minimize even the slightest risk to your baby.
