In general, children need x-rays more often than adults. Their mouths grow and change rapidly. They are more susceptible to tooth decay than adults. The American Academy of Pediatric Dentistry recommends x-ray examinations every six months for children with a high risk of tooth decay. Children with a low risk of tooth decay require x-rays less frequently.

X-rays allow dentists to diagnose and treat health conditions that cannot be detected during a clinical examination. If dental problems are found and treated early, dental care is more comfortable and affordable.

X-ray films detect:

• Cavities
• Erupting teeth
• Diagnose bone diseases
• Evaluate the results of an injury
• Plan orthodontic treatment

Particular care is applied to minimize the exposure of young patients to radiation. With contemporary safeguards, the amount of radiation received in a dental x-ray examination is extremely small. The risk is negligible. In fact, dental x-rays represent a far smaller risk than an undetected and untreated dental problem.

For most people, a complete radiographic survey should be done every 3 years, and a "check up" or "recall" set every 6 to 12 months. A complete set of x-rays is estimated to expose you to the same amount of radiation you get on a flight from San Francisco to Seattle.

Doctors use x-rays as an aid in diagnosing problems. Without x-rays, "seeing" the problem will be difficult if not impossible.
