Why does the dentist take X-rays?

Many diseases of the teeth and surrounding tissues cannot be seen when the dentist examines the 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, and some types of tumors. Finding and treating dental problems at an early stage can save time, money and often unnecessary discomfort. X-rays can detect damage to oral structures not visible during a regular exam. If you have a hidden tumor, X-rays may even help save your life. Your dentist will evaluate your need for X-rays based on the conditions present and your dental history. There are many benefits to having X-rays taken. Any additional questions or concerns should be discussed with your dentist.
