Dentists utilize X-rays for a number of reasons, depending on the situation. Sometimes they’re used to keep track of growing teeth and jawbones in children, or they help pinpoint areas of concern if the patient is subject to ongoing issues. Read on for a look at the different types of dental X-rays and the results they show. 

The Types of Dental X-Rays

Bitewing

The bitewing technique requires patients to bite down on a paper or plastic tab while the scan is made, so the dentist can observe the way the teeth line up when closed. They can also use this test to find cavities hidden between the teeth. 

Periapical

This type allows the dentist to see the entirety of two teeth, from the crowns to the roots. It’s used for in-depth information about a particular problem area or to examine a root and its surrounding bone structure.

Panoramic

As the name suggests, the X-ray machine will rotate around the patient’s head. This technique lets dental experts see jaw issues, wisdom teeth problems, or the condition of the jawbone for the possibility of dental implants. 

Occlusal

Done when your jaw is closed, this X-ray type shows how the teeth of your upper and lower jaws line up. It also allows dentists to identify issues with the palate or mouth floor. 

When Dental X-Rays Are Needed 

If you have symptoms of tooth decay, X-rays help your dental professional find weak points so they can be treated before further decay sets in or other teeth begin to break down. X-rays are also used before dental procedures like tooth extractions or root canals, and if you’re switching dentists, the new one may wish to use an X-ray so they have a clear idea of your dental situation from the beginning. 
 
Although dental X-rays involve the use of radiation, the limited exposure makes them safe for the majority of people. However, pregnant women should avoid them unless they’re experiencing a dental issue that requires X-rays before treatment.
