Dental x-rays are typically taken as part of a routine dental examination to help dentists diagnose and treat various dental problems, such as cavities, gum disease, and oral infections. They can also be used to monitor the development and placement of adult teeth in children and teens, and to evaluate the extent of damage caused by dental trauma.
There are several different types of dental x-rays, including bitewing, periapical, panoramic, and cone beam computed tomography (CBCT) scans. The type of x-ray used will depend on the specific dental issue being examined and the information that needs to be obtained. Dental x-rays are generally considered safe when performed by trained professionals, and the amount of radiation exposure is typically very low.
