What Are The Types Of Dental X-Rays?

January 26, 2023

Dental X-rays come in two basic varieties: intraoral (meaning the X-ray film is placed inside the mouth) and extraoral ( it implies the X-ray film is outside the mouth).

Intraoral X-Rays

Intraoral X-rays are the most standard type of dental X-rays taken. These specific X-rays allow your walk-in dentist to spot cavities, inspect the state of the tooth root and the bone surrounding it, monitor the development of your baby teeth, and assess the general health and condition of your teeth and jawbone.

Extraoral X-Rays

Although extraoral X-rays emphasize the jaw and skull, they also display teeth. According to a dentist near me is open on Saturday; these X-rays cannot detect cavities or identify issues with specific teeth because they lack the level of detail observed in intraoral X-rays. Extraoral X-rays are instead used to check for impacted teeth, track the growth and development of the jaws relative to the teeth, and find any potential issues with the temporomandibular joint or other facial bones.

What are the main types of intraoral X-rays?

According to dentist offices near me, there are various types of intraoral X-rays, each displaying multiple aspects of teeth.

Bitewing X-Rays

On Bitewing X-rays, you can see the top and bottom teeth of the mouth in detail. Each bitewing has a tooth visible from the crown to the level of the supporting bone. Bitewing X-rays detect dental decay between teeth and changes in bone density brought on by gum disease. These Digital Dental X-Rays are also valuable for determining the fillings’ marginal integrity and the crown’s proper fit (or cast repair).

Periapical X-Rays

Periapical x – rays show the complete tooth, including the crown and the region of the jaw where the tooth is attached beyond the end of the root. Also, the entire tooth dimension is visible on each periapical X-ray, including all the teeth in one upper or lower jaw section. X-rays from the periapical region check for root and surrounding bone structure anomalies.

What are the main types of extraoral X-rays?

Your 24-hour emergency dentists near me may take different extraoral X-ray types.

Panoramic X-Rays

Panoramic X-rays show every tooth in the top and bottom jaws on a single image, including the mouth area. This type of X-ray also helps detect the locations of fully and partially emerging teeth, identify tumors, and spot impacted teeth.


Tomograms can only see one layer, or “slice,” of the mouth; the rest is hidden. This type of X-ray also helps examine complex structures to see clearly. It may include when other structures are very close to the one that needs to be studied.

Cephalometric Projections

Cephalometric projections show the complete side of the head. This particular X-ray also helps assess the teeth concerning the jaw and the patient’s profile. This kind of X-ray allows orthodontists to create their treatment plans.
