Pediatric dentists are particularly careful to minimize the exposure of child 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.
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.
