When visiting your dentist, it’s not uncommon to undergo an X-ray. These diagnostic procedures are used to look for hidden issues with your teeth, such as developing cavities or impacted wisdom teeth. Dentists use a variety of X-rays, each of which serves a distinct purpose. 

A Guide to Common Types of X-Rays

1. Periapical

Periapical (PA) X-rays are capable of capturing an image of the entire tooth, from the crown to the area where the root is attached to the jaw bone. To take a PA X-ray, dentists use a device that consists of a metal rod and ring, which is situated at one end.

You’ll be asked to bite down on the device so the ring is surrounding the area being imaged. PA X-rays are often used to assess the health of the jaw bone and tooth root, which can be compromised by infection or decay. 

2. Bitewing 

Unlike PA X-rays, bitewings capture your teeth above the gum line and a portion of the root, as opposed to the entire tooth. They’re integral in identifying decay hiding between teeth, which can be difficult to detect otherwise.

To take a bitewing X-ray, your dentist will place a cardboard or plastic film in your mouth, which is kept stable when you bite down on it. An X-ray camera will then be positioned near your mouth to capture the image.

3. Full Set or Full Mouth

Dentists sometimes combine X-ray techniques to get a comprehensive view of your oral health. This is the case with full mouth X-rays, which are also referred to as a full set. Taking individual photos of each area of the mouth—which entails undergoing both bitewing and PA—provides insight into cavities, abscesses, impacted teeth, bite, and jaw bone health.

Full mouth X-rays are usually taken when a patient visits a new dentist for the first time, as they establish a baseline for oral health going forward.
