X-rays help dentist to detect problems that would be missed by just looking in your mouth, such as:

 Xray Chin

1) cavities between teeth or under fillings

2) trouble with teeth and jaw development in children and teens

3) bone loss from gum disease

4) jaw bone tumors


Sometimes x-rays are needed as part of your dental treatment for diagnosis if you have tooth ache or in case of tooth fracture. 


Types of Dental X-rays


Common x-rays used in the dental office include bite-wing, periapical, and panoramic x-rays. Bite-wing x-rays help dentist check for tooth decay between the back teeth or under dental fillings. Periapical x-rays help dentist observe conditions below the gum line, showing the roots of the teeth and surrounding bone. Panoramic x-rays use a machine that rotates around the head. It produces a long film that shows the entire jaw and all of the teeth in one image.

Cone-beam computed technology is used to create a 3-dimensional image from a series of images. Because it relies on multiple images, the radiation exposure is higher than that of commonly used x-rays and is used for surgical treatments. 


Are Dental X-rays Safe?


Because dental x-rays expose us to radiation, patients sometimes wonder if they are safe. Routinely we are exposed to radiation from a number of sources, even sunshine, air and soil around us. 

To help limit the amount of radiation exposure to your thyroid gland when taking x-rays, your dentist may cover your throat with a special collar.
