X-Ray Use and Safety

Q: How often should a child have dental X-ray films?

A: Since every child is unique, the need for dental X-ray films varies from child to child. Films are taken only after a complete review of your child's health, and only when they are likely to yield information that a visual exam cannot.

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.

Q: Why should X-ray films be taken if my child has never had a cavity?

A: X-ray films detect much more than cavities. For example, 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 more comfortable and affordable.
