digital x Ray

Dental X-rays (radiographs) are images of your teeth that your dentist uses to evaluate your oral health. These X-rays are used with low levels of radiation to capture images of the interior of your teeth and gums. This can help your dentist to identify problems, like cavities, tooth decay, and impacted teeth.

Dental X-rays may seem complex, but they’re actually very common tools that are just as important as your teeth cleanings.

Why dental X-rays are performed

If you’re a new patient, you’ll probably undergo dental X-rays so that your new dentist can get a clear picture of your dental health. This is especially important if you don’t have any X-rays from your previous dentist.

Children may need to have dental X-rays more often than adults because their dentists might need to monitor the growth of their adult teeth. This is important because it can help the dentist determine if baby teeth need to be pulled to prevent complications, such as adult teeth growing in behind baby teeth.

Preparing for dental X-rays

Dental X-rays require no special preparation. The only thing you’ll want to do is brush your teeth before your appointment. That creates a more hygienic environment for those working inside your mouth. X-rays are usually done before cleanings.

At the dentist’s office, you’ll sit in a chair with a lead vest across your chest and lap. The X-ray machine is positioned alongside your head to record images of your mouth. Some dental practices have a separate room for X-rays, while others perform them in the same room as cleanings and other procedures.

After dental X-rays

When the images are ready — instantly in the case of digital X-rays — your dentist will review them and check for abnormalities. If a dental hygienist is cleaning your teeth, the dentist may go over the results of the X-rays with you after your cleaning is done. The exception is if the hygienist discovers any significant problems during the X-rays.

If your dentist finds problems, such as cavities or tooth decay, they’ll discuss your treatment options. If your dentist finds no problems, keep up the good work!

The outlook

Depending on your age, health, and insurance coverage, X-rays may be performed every one to two years. Be sure to commit to your appointments and see your dentist sooner if you experience any pain or other changes in your mouth.
