Concered about Dental X-rays?

Why should X-ray films be taken if my child has never had a cavity?
X-ray films detect more than cavities. X-rays may be needed to survey erupting teeth, diagnose bone diseases, evaluate the results of an injury, or plan orthodontic treatment. 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 often more successful, comfortable and affordable.

How safe are dental X-rays?
Pediatric dentists are particularly careful to minimize the exposure of pediatric patients to dental x-rays. With the contemporary safeguards our office has in place, the amount of radiation received in a dental X-ray examination is extremely small and the risk of dental X-ray related disease is negligible. Dental X-rays, in fact, represent a far smaller risk to a child than an undetected and untreated dental problem.
