During your dental X-ray, a small amount of electromagnetic radiation is used to create an X-ray image of your teeth, roots, gums, jaw, and facial bones.
Panoramic x-rays are like panoramic photos. They show the entire mouth instead of just a “snapshot” of a few teeth. Unlike other dental x-rays, these images are taken from outside the mouth instead of inside. The patient stays still while an x-ray machine moves in an arc from one side of their head all the way around to the other.
There are four common types of dental x-rays, each used for different purposes Bite-wing x-rays are the type that most people are familiar with. They get their name from a tab on the x-ray film.
