What Happens During a Dental X-ray Procedure

Most dentists, including us, recommend patients get dental x-rays once per year, or more as need dictates.

However, for those who’ve never gone through the process, it can be a bit intimidating. The good news is that there’s absolutely nothing to fear from x-rays. They process is simple and painless, and gives your dentist an in-depth understanding of how your teeth are doing so they can take a proactive role in keeping your teeth and mouth healthy.

In the long run, that means fewer cavities, less mouth pain — and a healthier smile!

To help you understand x-rays, we’ll cover what it’s like to get an x-ray, how they help keep you healthy, as well as cover the different types.

What’s it like to get a dental x-ray?

Most dental x-rays are part of a routine dental check-up.

Once your teeth are cleaned, your hygienist will ensure your chair is adjusted to an upright position, then they’ll place a lead apron over your chest and wrap a thyroid collar around your neck. This is to protect sensitive parts of your body from the light levels of radiation that come from x-rays. It’s just one step that ensures your dental x-rays are safe and beneficial for your health.

Once you’re safe and in position, the hygienist will ask you to open your mouth, then place an x-ray sensor or film along one side of your mouth, then ask you to bite down to keep it in place.

They’ll position the camera, take the picture, and then repeat for the other side of your mouth.

Discomfort

There should be no pain during the preparation for or the taking of your dental x-rays.

However, depending on the size of your mouth, and its shape, there may be some discomfort as the hygienist places the film or sensor in your mouth. This discomfort should be mild. If it feels uncomfortable, let your hygienist know and they’ll do their best to make the experience as comfortable as possible.

If you know you, or a child you’re accompanying, have a sensitive gag reflex, let the staff know and they will take measures to sidestep it.

Types of X-rays

Depending on your needs, there are a variety of x-rays your dentist may take, including:

Bitewing X-Rays

These are the most common dental x-rays, and they are typically taken each year. These give your dentist a good overview of your oral health, from the state of your teeth, their roots and even the bone that serves as the foundation of your bite.

Periapical X-Rays

This is a focussed dental x-ray that your dentist may take when you are having trouble with a certain tooth. It shows the tooth in question from the tip of the root to the crown of the tooth. It helps your dentist understand what the problem is so they can accurately diagnose and tackle the problem.

Occlusal X-Rays

This is one of the least common dental x-rays as it is aimed not at your teeth but at the roof or floor of your mouth. This helps your dentist check for problems like extra teeth or impacted teeth, mouth abnormalities, jaw issues, and growths such as tumours.

Panoramic X-Rays

Typically taken every three to five years, or as recommended by your dentist, panoramic x-rays cover the vast majority of your mouth and help your dentist or orthodontist prepare for braces or surgeries, such as tooth extractions.
