IF WE ASKED you to list three things that happen in a typical dental exam, dental X-rays would probably be one of them. But do you know what they’re used for? It depends on the type of X-ray, so let’s look at what these are.

Getting The Wide Shot With Panoramic X-Rays

If you’ve ever stood on a circular thing with your chin on a little platform and been told to stand still for a few seconds while a machine spun around your head, you’ve had a panoramic X-ray. This is the most common type of extraoral (outside the mouth) X-ray.

Panoramic X-rays show the entire mouth in one image. In them, we can see incoming adult teeth and wisdom teeth, including impacted ones, which is how we can determine whether there is enough room for them and if they’ll come in without any extra help. This type of X-ray also makes it easier to detect abscesses, tumors, and cysts.

Enhance: Periapical X-Rays And Bitewing X-Rays

In photography, wide shots show a lot, but they aren’t as useful for details as a closeup. The same is true in X-rays, which is why we don’t rely only on the panoramic image. The next level of dental X-rays are the bitewing X-rays. These intraoral (inside the mouth) X-rays focus on a specific area inside the mouth at a time, and we usually take one for each of the four quadrants of your mouth.

Bitewing X-rays give us a better view of the gaps between teeth, which are hard to see with the naked eye. These images make it easy to check for tooth decay and cavities in those areas. When we need to get even more detailed, we take periapical X-rays, which hone in on an individual problem tooth . These can be taken alongside bitewing X-rays.

Are Dental X-Rays Safe?

Dental X-rays involve brief exposure to low levels of radiation, but they are considered extremely safe. The short exposure time and protective coverings like the lead apron ensure that radiation exposure is as low as possible. We also only take X-rays as often as we absolutely need to, which further reduces exposure.

Factors that determine whether or not X-rays are necessary include the patient’s age, stage of dental development, oral health history, risk factors for various conditions, and whether or not they are presenting symptoms of oral health problems.
