Dentists Use Them for Diagnosis

Dental x-rays are an important diagnostic tool used by dentists to identify dental issues that are not immediately visible during a dental examination. Dental x-rays are used to evaluate things including: cavities (especially between the teeth), the health of the tooth roots and jawbone, and the presence of wisdom teeth.

There are different types of intraoral x-rays known as: bitewing, periapical, and occlusal x-rays. These x-rays are used to evaluate the health of the teeth, roots, and surrounding bone. They can also be used to detect cavities. While extraoral x-rays encompass the entire mouth, intraoral x-rays tend to focus on a specific area.
