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 treatmentParticular care is applied 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.
