You may have heard that dental x-rays use radiation, and the lead lined bib may make you a little worried about your child’s safety. However, it is important for parents to understand that the radiation used in dental x-rays is significantly less than medical x-rays used to look for broken bones. X-rays have been proven to be safe and effective ways for doctors and dentists to see what they can’t see normally. X-rays can help dentists make sure your child’s teeth are coming in healthy and help find early signs of tooth decay before they spread.
