How It Is Done
Dental X-rays are taken in the dentist's office. The X-ray pictures are read by your Reference dentist Opens New Window.
- A dental technician will cover you with a heavy lead apron as you sit upright in a chair. This apron shields your body from X-rays. The technician can cover your neck with the collar of the apron (called a thyroid shield) to shield the Reference thyroid gland Opens New Window from radiation.
- Everyone else in the room wears a protective apron or stays behind a protective shield.
- The dental technician will have you bite down on a small piece of cardboard or plastic. The cardboard or plastic holds X-ray film. You may do this several times to get pictures of all your teeth. Some X-ray machines have a camera that circles your head and takes pictures of your teeth while you sit or stand.
- You may want to rinse your mouth before and after the X-rays.
Some dentists use digital radiography. This method uses an electronic sensor instead of X-ray film. An electronic image is taken and stored in a computer. This image can be viewed on a computer screen. Less radiation is needed to make an image with digital radiography than with standard dental X-rays.
