Many diseases of the teeth and surrounding tissues cannot be seen when your dentist examines your mouth. An X-ray examination may reveal:

• small areas of decay between the teeth or below existing restorations (fillings);
• infections in the bone;
• periodontal (gum) disease;
• abscesses or cysts;
• developmental abnormalities;
• some types of tumors.

Finding and treating dental problems at an early stage can save time, money and unnecessary discomfort. It can detect damage to oral structures not visible during a regular exam. If you have a hidden tumor, radiographs may even help save your life.
