The following types of dental X-rays are commonly used:
- Bitewing X-rays use the least amount of radiation and show the upper and lower back
teeth in a single view. They are used to detect decay between the teeth and to show how
well the upper and lower teeth line up. They also show bone loss that usually indicates
the presence of severe gum disease or a dental infection.
- Periapical X-rays show the entire tooth, from the exposed crown to the end of the root
and the bones that support the tooth. These X-rays are used to detect dental problems below the gum
line or in the jaw.
- Orthopantomograph (OPG) X-rays provide a broad view of the jaws, teeth, sinuses, nasal area,
and temporomandibular (jaw) joints. These X-rays reveal problems such as impacted teeth,
bone abnormalities, cysts, solid growths (tumors), infections, and fractures.
