Last updated December 19, 2006

Dentists use X-rays (also called radiographs) for many reasons. X-rays can help diagnose tooth decay, gingivitis and periodontal disease. They allow the dentist to see the sizes and positions of teeth that haven't come in yet. X-rays also can show problems with fillings or crowns, and help your dentist plan for braces, dentures, implants or other kinds of dental work.

If you're wondering why your dentist wants you to have a certain type of X-ray, or how often you should have X-rays taken, check out the chart below. It's based on guidelines put out by the American Dental Association and the U.S. Food and Drug Administration.
