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
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. Dentist will evaluate your need for X-rays based on the conditions present in development. There are many benefits to having X-rays taken. Any additional questions or concerns should be discussed with your dentist.
